TCMP Wifi playback.

Has anyone managed to get a standard divx type format playing without having to buffer over wifi ?
Playing like a 700mb divx, avi or whatever it will stop to buffer every minute or so. Is there any way to play with any of the buffer settings to get it to play a file back without any buffering ?
I know I can convert the files to ppc and they would play fine but I was just wondering if there was a way to avoid this.

+1 Yeah, I would love to know this one. Is there any way to get a player to load a sufficient amount into memory (SD, storage) to play smoothly? I am using Resco Explorer 2005 and TCPMP.

No answer here, but I'd like to know this too! I tried to watch something over WiFi and it was shocking. Damn... that... spinning... pie... chart... thing! :lol:

I'm kinda surprise..certain wmv files I've played does not have any buffer..
But i've compared 2 video in Mpeg and Wmv format. the Wmv format (320X240 pixel, bit rate 234kbps,16bit,2(stereo) audi sample rate 32Khz) can play the movie smoothly.Perhaps we should look into the size and format or the bitrate?Sorry I'm not a pro in this..

Spooling via VLC (Macintosh) to TCPMP over WiFi works smoothly without buffering on all the files i have tried. For those formats not supported you can transcode the video and audio and set the bit-rate at whatever you want.

Been playing with the settings, and while the video only is a little choppy on higher bitrate stuff with fast movement, I'm no longer experiencing the dreaded piechart for most stuff.
Could not tell you which of my settings are affecting it though, but theoretically, how can the wifi network be the weak link? Even the slower version of wifi should be able to stream this amount of data....?
Of whats in my vid folder right now, I'm experiencing the following:
Surface - not full 24fps via wireless, but extremely watchable, no piechart
xvid - 624x352 - 1104kb/s, 128kb/s audio
Sleeper Cell - not full fps but again extremely watchable, no piechart
xvid - 624x352 - 865kb/s, 131kb/s audio
Powaqqatsi - awful jerky quality. No piechart, but the video freezes every couple of secs, while audio continues. Unwatchable
divx5 - 592x320 - 1654kb/s, 448kb/s audio
Hidden Fortress - Works perfectly due to low bitrate/screensize, either in 100% mode or fit-screen mode - tcpmp doesn't do subtitles though, argh!!
xvid - 416x176 - 509kb/s, 192kb/s audio
Intoxicated - Works well enough in 100% or fit-screen mode - got one piechart though
xvid - 512x288 - 946kb/s, 115kb/s audio
Used GSpot to find out bitrate etc, highly recommend it.

Indeed, 802.11b at feeble rate SHOULD be able to handle it. It can make a difference if the hard-disk on the network PC is fragmented.
I would defragment mine, but they are too full so it'd take hours... doh!

Good tip - mine WILL be highly fragmented, I let it get near full a few times.
Will run it overnight, see if it improves matters.

Still found it had to buffer even when switching the audio to mono and reducing the video quality to low.
There is obviously a bottle neck somewhere on the universal. I had this problem on the wizard but the impression I got was it was down to the cpu. I thought the Uni may have been okay but its just the same.
Im assuming maybe the cpu is doing so much in tcmp to decode the file, there isnt enough time left to actually get the wifi running smooth enough.
Has anyone tried to run a file of large divx size from a memory card to see if its even an issue from there ?

Will do that right now with powaqqatsi, the highest bitrate one from my list above.
EDIT: Works perfectly at 100% and fit-screen mode. Smooth as a babys bum, even fast moving stuff.
Processor ain't the bottleneck as such...

Yup agree with you,I've tried a large divx size movie and it play the move smoothly on SD card

So maybe the answer is the tcmp streaming ? Having said that its the same with webpages. They dont load anywhere near as quick as on a desktop so for me even b wifi isnt getting anywhere near to capacity never mind bringing g into the mix.

Hello all first post on forum.
I need some feedback on this:-
I have changed the TCPMP Player settings as follows
Normal Buffer size 49984KB
Preload at underrun 200%
I still get the video to stop with pie chart appearing but its less frequent but the stop is a bit longer. It’s a bit better but not perfect maybe someone can try some other numbers and combinations. For me these are the best I could get.

Could someone give me some tips as to how i can stream video's on my PC to my jasjar.
I have a Linksys WAG54G router.
Appreciate it.

Doc:
You have to make the files on the host pc 'shared' (right click> properties > sharing.. on windows xp). Once youve done that, use a file explorer program such as Resco File Explorer to access the host PC from your phone via your wifi network. Browse to the file you want, then tell it to play!

Hi Richard,
Thanks for the quick reply.
I have already done what you have said. But when i try to map a drive through resco explorer,i get an error saying "No computer found in the network. Check your network card or modify settings to specify your network subsets"
What do you suppose i am doing wrong?
Thanks.

Itll be an issue with the way windows manages networks... check settings such as the workgroup/domain you are on (My computer > Computer name)
Just fiddle around until it works

Ummm, sorry if i am sounding thick Richard.
I haven't setup any workgroup or domain. This is my home wireless network and i am the only one using it. My computer name is "Universal". When i try to map a network drive through resco explorer, it doesn't even see a computer with that name.
What do you think?

Dont worry :-D
The only reason I know a lot about wireless networks is that mine is always breaking ;p
Workgroups and domains are silly little things the Microsoft likes you to organise your computers on a network into. Regardless of the fact that you only have one, that one PC still needs to be grouped, so old Bill is happy. I havent the foggiest what the practical differences are between workgroups and domains, but I know you may only be in one of the two at once. Check on the My computer page I mentioned, see if anything looks awry. Failing that, tick/untick boxes until it works....

Hi again Richard,
Well, i finally got my jasjar to see my computer through resco file explorer.
NEW PROBLEM!!!
When i click on the share button, i get the following error:
"Cannot map network path. Network resource cannot be found or you do not have a permission to access the network. Contact your network administrator".
All firewalls are off. I dont know what is blocking it. Suggestions?

Recommended Bitrate for good sound quality

Hi,
I was wondering if any of you guys know whats like the ideal bitrate of a file (especially mp3 files) before putting them onto the phone. I'm using this great software called cdex that allows me to downsize a file majorly by reducing the bitrate. But am I compromising on sound quality for space on my card by doing this? The software turns a 6MB mp3 file into like 3MB. I remember reading somewhere that most handheld devices (phones, MP3 players etc) cant play files of a bitrate higher than 80-90kbps. Meaning u cant tell the difference in sound quality after 90 kbps. Is that really true? If someone out there knows....please do let me know.
Thanks in advance

Man, the guy who wrote it probably was from XV century
I'm always copying the same files I have on PC, without converting or something. Just copy - paste. Elf supports SD cards up to 16 GB, so I don't think file size is a problem. If you really want to convert files, use 128 kbps, it should sound good and don't take too much space.

Video playback problems - Coreplayer, TCPMP : SOLVED/SOLUTION

PROBLEM SOLVED - CONCLUSION OF THREAD updated 9/3/10:
1). Coreplayer and TCPMP don't work well on my device when playing back avi (divx/xvid) because they don't support hardware accelaration, although others seem to have no problems which still confuses me. Playback is juddery dropping many frames. I have tried Shasaraks settings (which are the best) and all others with no luck.
2). Because WMP and the HTC player don't support avi (divx/xvid) converting to mp4 is the only option for me.
3). CONVERSION: I have tried many converters including: TMPGEnc.XPress, handbrake, xvid4psp, mediacoder and others. The ones that do work well for the HD2 all have the same problem and that is a delay in audio putting speech out of sync when played back on the device. Even when playing back avi's in coreplayer i had to manualy adjust the sync.
The only converter that works well and is fast and can put the audio in sync for playback on HD2 is winmenc available here (freeware) http://winmenc.blogspot.com/
Download my profile which has the audio sync tweak already in it (thanks to Kr00ton) and put it into the profiles folder. I have tweaked Kenkiller's original profile, see here for info: http://forum.xda-developers.com/show...7&postcount=38
I have changed Kenkillers profile from 2000 to 1000 kbps to save file size and have also got rid off the 2 pass encoding to save time (and lots of it!). You also need to tick FIT TO WIDTH AND SPEED & QUALITY CONTROL AND MOVE IT TO FASTEST. I done various tests and found no noticeble difference to SD videos doing it my way. This speeds up conversion time to around 30 mins for a 700mb avi and keeps the file size about the same as the original.
If you have more time on your hands and or you are converting HD then maybe use Kenkillers original profile, although i converted HD stuff in my profile and it looked great. It all depends if file size and conversion time is an issue for you.
4). For some reason the HTC player still judders for me, i'm pretty sure it didn't do that in stock rom 1.44 but it certainly does on my 1.66 ROM leaving only WMP that performs perfectly It's a shame that it isn't very finger friendly for srolling through the video etc but i'll live with that.
I can only report my findings and experiences, you may not have the same issues i have had. Conversion may wield different reults on other OS's. I'm using windows 7 64 bit and can confirm that when i used winavimp4 converter on xp it was perfect but used on windows 7 it puts audio out of sync. Having said that it is without a doubt the fastest converter i have come accross converting a 700mb file in around 10 mins on windows 7 64 bit. It was around 30 mins on my old xp machine.
5). I can now relax and enjoy my films on my HD2, which is the main reason i bought it!
ORIGINAL 1ST POST
I bought this phone because of its screen. I watch movies on my long journeys to work and i'm getting increasingly frustrated with the phones poor performance on playback.
Coreplayer judders with many dropped frames no matter what settings (tried shasaraks direct draw settings) or version of coreplayer i use and disabling sense and using plane mode makes no difference whatsoever. It will play flawlessly for a while then judder then be ok then judder on and on...
So i decided to convert to mp4:
coreplayer still has poor performance. HTC player was ok but since upgrading to 1.66 it's performing worse than coreplayer now (yes, i did a hard reset after flashing)
The only player that works is wmp. I now have some questions:
1). Is there an option in wmp to sync the audio manualy like in coreplayer? some films are slightly out of sync.
2). are there any other players that work well on the HD2 apart from tcpmp (tried that, same results as coreplayer)
3). CONVERSION:
What are the best settings for video conversion for the HD2? If I can't use coreplayer to play avi this is my only solution and aslo solves the problem of coreplayer not supporting ac3 audio. I'm talking bitrate etc for video and audio. If you are succesfully converting video what converter and settings do you use? PLEASE!
I tried searching but couldn't see a thread dedicated to optimum conversion settings for the HD2.
4). Could the problem lie with my 16gb sandisk sd card? i noticed another thread for the blackstone where a cab was designed to speed up the cards performance by 3 times, is there something like this for the HD2 and would me formatting it to fat 32 make any difference at all to my problem?
This is really winding me up now and i've spent hours messing with settings etc, the one function i really need and it wont perform which i find very surprising for a phone that has this super fast snapdragon processor.
PLEASE HELP ME
END OF ORIGINAL POST, PROFILE FOR WINMENC BELOW

1) no
2) none even close to that
3) can't tell, as I don't really do it much, coreplayer works well for me
4) could be, as coreplayer works well for me.

Could well be the card, as it sounds like it gets to the end of a buffer, buffers, then continues, causing the lags.

I know that reporting my own experience is of relatively low usefullness to you as it's not step by step instructions on how to solve your problem, anyway:
1) I use TCPMP to watch AC3 audio-encoded series like frasier
2) I use Coreplayer to watch non AC3 encoded series like sex and the city
3) tcpmp is slower than coreplayer for those videos that coreplayer CAN play, I get ~120% bench for SATC in coreplayer and ~90% in tcpmp, but nonetheless I can watch everything (...that I tried until now) in tcpmp without noticing the slightest issues, and I always "zoom to fit screen", which means the video fills the entire 800x480 resolution
4) I watched videos on my old ipaq 214 as well, sure we're talking about a different device, but we're aso talking about a device with a 600MHz cpu and without an accelerated graphics subsystem (and I do have chainfire patch for the graphics subsystme of my hd2)... well I only used tcpmp on the 214 and no issue there... and I watched the whole Death note series, crappy bench results but no issues with jumps in the video
5) I have a 16gb class 2 sandisk microsd, and despite it being class 2, I get ~7mb/s transfers both ways in the sd reader of my laptop, so if we're using the same memory card, that should not be the problem...
6) probably you watch "heavy" encoded movies?

Look at this:
http://forum.xda-developers.com/showpost.php?p=5331497&postcount=38
Post Nr. 38 and download th profiles.
Use Winmenc 0.81 Beta (Freeware). Copy the downloaded profiles into Winmenc subfolder "profile".
Edit the profile like told in this thread
http://forum.xda-developers.com/showthread.php?p=5341496#post5341496 Post Nr. 32 from krooton.
Important ist to set the audiodelay.
With this solution you can get very good *.mp4 Files with audio in sync playable with Manila album or Mediaplayer.
I tried a lot of things but this was the only way to get good video with audio in sync.
Sorry, but english is not my first language.

For coreplayer i'm using v 1.3.5 build 7340 but the newer 1.3.6 build 7427 also performs the same.
What version are you guys using?
Failing that i'll format the card to fat32 to see if that makes a difference and have a look at that winmenc.
Any other suggestions are very welcome

defo not this. I converted a film to the lowest spec audio and video wise and it resulted in 350mb file... It played the same as the 1.2g original!

I used handbreak to convert to MP4 and then used the built in player in sense.
Seemed to be HW accelerated as 45minutes of playback took about 8% of the battery charge and I would expect doing soft decode of H264 would take more than that.
Only downside was waiting 15minutes to go from 720p to iPhone profile in handbreak. I am going to experiment with remuxing
Jim

I have created a preset in handbrake specifically for the HD2 - Let me get home and post it back for you.
have been using this - converted about 20 movies and loaded up around 10 on the HD2 for a trip. All of them played perfectly in HTC album (Looks like it's hardware accelerated). Approx 4-5 hours on a single full charge (around 2 1/2 movies back to back).
Best part - converstion takes about an hour on a 4 yr old laptop - should happen much quicker on new ones.
Source files are all mkv (for Blu-ray rips) or iso (for standard DVD)

please do mate, looks like a nice converter, if you post the sttings you are using i'll give it a bash tonight.
I don't know what is going on with coreplayer, i used it a while ago and it played lovely, about 2 drops in 10 mins. I just tried again, 11 drops in 10 seconds what does this tell us!?!?!?!?

Could also be that you have something running in the background that's using the CPU badly...

This thread is worth checking out for video settings: http://forum.xda-developers.com/showthread.php?t=582122
A converter that is reasonably idiot-proof (although its maximum bitrate is a teensy bit too low, IMO) is MP4ForHD, which you can find here: http://forum.xda-developers.com/showthread.php?t=478050 I think it lets you incorporate an audio delay into the video (thus negating the need to do it in the player).

I've bought Core PLayer and Kinoma PLay but the only one i use to play my videos and series is TCMP, its litter and complete doing its tasks.
I prefeer TCMP.

Is what i thought but no, everything is shut down. Does the same after a soft reset. Disabling sense and using plane mode also makes no difference.
But like i say, soemtimes it works and sometimes it drops like a mother f*****
it's completely random
what i will try is another sd card, i got the 2gig one indoors, i'll put the same vid on that and report back... all rather boring but it's doing my head in and i don't like being beaten

thanks, will take a look

I just don't see the point in encoding especially for a mobile device.
That's iphone madness, not ours
I've been watching videos encoded for proper pc's since when I had my ipaq hx2400 back then, after that I kept doing it with my ipaq 214, and now I am happily doing the same on the HD2. I am sure there's something that's preventing jonbaker from watchgin movies normally, and using an alternate encoder is not a "solution" but a complication. Occam would say the same.
More specific info on file size/length/codec/bitrate/tcpmp-coreplayer bench results/microsd transfer rate (tested with read/write operation in usb disk mode) would be useful.

If memory card access is causing the problem with CorePlayer then you could try increasing the amount of memory CorePlayer uses to buffer. You could also try out these registry settings which sometimes improve SD card performance: http://forum.xda-developers.com/showpost.php?p=5547319&postcount=8

any chance you can suggest what i increase the settings to in the coreplayer memory buffer? not sure what im doing there! wouldnt mind giving that a go.

I'm operating entirely on guesswork, so no, no chance at all!!! I guess it needs to still be small enough that there is no danger of running out of memory on the phone, but larger than the default value. Might not make any difference, of course, depends on what's causing the bottleneck.
Have you tried getting CorePlayer to play video and audio in the background and then opening up the task manager to see what the CPU usage is doing? That might at least tell you whether it's a lack of processing power as opposed to something else.

RIGHT i set coreplayer to play in background: BUILT IN TASK MANAGER:
mem - 7.94m CPU sitting around 45 - 65%, then will drop to around 20% then back up to 60%
RESCO TASK MANAGER:
mem - reports 2.68m
don't know why they give different results memory wise don't think resco task manger gives cpu usage
is all that normal?

streaming 1080p from a media server on a dual band connection on this

Anyone dont it without too much stutter? A good buffer? I find Vplayer the best for building up a buffer with PS3 Media server.
I'm in the market for my first tablet and want to know whether the Nexus 10 or any tablet can do this before I commit to a purchase.
That or wait. Or just buy a simple e-reader

Even though I don't have a dual band router I found that using an OTG Ethernet adapter gave me the best throughput for stutter free HD video playback. Of course the bitrate of your videos will determine your ultimate experience. I also use Ethernet powerline adapters to extend my wired network to rooms where a WiFi signal is problematic.

Yes the Gigabit Ethernet adapter reviewed in the link is a USB adapter, which I attached to a an OTG microUSB to USB cable to the Nexus 10 microUSB port. That specific adapter is supported by stock Android v3.3.x and higher, which means out-of-the-box compatibility. If you purchase an Etherent adapter make sure its chip set is supported on Android many are not supported.
I successfully tested streaming 1080p video (11.2Mps) but my comments are all about maximizing the bitrate that can be streamed to your Nexus 10. With ordinary single band WiFi I can watch stutter free 1080p YouTube videos but those videos have significantly lower bitrates than Blu-ray video files. A 720p HD video with a very high bitrate could overwelm your network bandwidth resulting in stutter.
The post I linked mentioned the bitrates of the various video files I test. Check to see how much higher your videos are versus what I tested.
I'm going to suggest that you copy a sample 1080p video file from your collection, who's bitrate is typical of what you want to stream, to your Nexus 10's internal storage. Then play it to see if its stutter free. That will eliminate knowing if network bandwidth is your limiting factor. You will need to use a video player that configured to use hardware playback such as MX Player or to acheive an acurrate test.

Thanks Sammy. One problem I have that I can use a suggestion is testing that network stutter, bandwidth, transfer feeds and pings WITHIN my network...are there programs that allow me to easily do this (ie test the speed between my computer and the router)? This seems to be one of the most useful yet difficult things to test.

I once looked for such an app but found most them were Internet focused. You could try either of the suggestions below.
If you don't want to install apps or root your Nexus 10 then simply pick a video file at least over 300Mgs. Get its exact byte count (file size). Using an android file browser (e.g. ES File Explorer) that can access your networked server, do a file copy from your server to the Nexus 10 while timing how long it took. Repeat the test 5 times recording each copy time. Then apply this formula to calculate bandwidth.
File size in bytes / total seconds for all 5 copy test runs / 5 / 1024 / 1024 = Megabytes / sec
OR from the link specifically look at the "Test descriptions" section it shows how I did the tests and made the calculations of the bandwidth average that WiFi and Ethernet could achieve.
You would need to install Busybox (root required) and a Terminal app from the playstore. I would also suggest an alternate keyboard for when you use the terminal "Hacker's Keyboard". The Hackers Keyboard includes keys that emulate a PC keyboard. I found it to be a God send.
You need Busybox for the "wget" utility and a web server on your network with a file of known size.

Great stuff Sammy I appreciate it. When I do have the time to test this stuff out I will post an update. This is the kind of testing I do on my end vs (it works with MXplayer) and is really great to test Metrics. I appreciate the thoughtful posts from you brother

Best way to convert long recorded lecture(wav) to mp3

Best way to convert long recorded lecture(wav) to mp3
Finally, found a good recorder which flawlessly records my long lectures and easy transfer to pc. App name : yovisoft recorder.
But size of the recording is huge, 300mb for 2.30 hours lectures. And it gets too heavy on my sd card.
I tried audicity software to convert the wav to mp3 which gave me 200 mb mp3 file. Still huge, isn't it.
Than I directly copied wav to my lumia via mtp. As soon as i copied it prompted to convert. I selected yes, it gave 14mb file but it very dull quality.
I don't have deep knowledge of sounds/frequency/bitrates, please gave me best way of good quality and low in size (up to 25~50mb) way to convert. I have 16gb sd card.
Quick questions
1. Which is best audio format for hearing recorded lectures.
2. Which bitrates-frequency will be ideal for recorded lectures.
3. Any direct software on pc, dedicated for such jobs?

Try audacity. It is a good converter between various formats.

He tried (and misspelled) Audacity, but he clearly didn't know how to use it because he got a huge file. Set the quality of the created file to something like 64kbps (if you use constant bitrate MP3 for voice, that's probably good enough, although MP3 isn't great for voice) and probably mono instead of stereo (halves the size, at the cost of losing the difference between right and left channels if those are present to begin with).
Actually, the fact that over two hours of uncompressed audio was only 300MB is *very* suspicious. For perspective, an audio CD (which is uncompressed, much like WAV) is only 72 minutes of audio (half of what you're trying to store) for roughly 700MB of data. Storing the amount of audio you're talking about at the quality of a CD would take about 1.5GB, not 300MB. Making it mono instead of stereo would halve that, but you're still talking a factor of 2.5x compression that isn't accounted for. Either the recording quality is very poor, or it's already compressed.

Well, the default lame encoding properties offer pretty good compression rate.
He either:
a) didn't have WAV as the original file format
b) Didn't convert to mp3 but to some lossless format.
c)messed up with the lame encoder properties.
hint: usually, bigger numbers tend to generate bigger files. The only exception is the compression rate, which only appears for lossless codecs.

Both of you guys (#2 #3) are genius.
Than thanks for understanding my typo @GoodDayToDie.
I use yovisoft recorder as i said, it gives me wav file, i dint knew all what you detected and conveyed me.
I need time to understand as my background is Accountancy Finance and Taxation.
I will do R&D and revert asap.
Thank you, i found exactly what i was looking for. Stay connected please.

is it stable to record long lectures? About 3 hours.

I'm not shure about 3 hours, but it recorded without problem 1,5 hour which was something about 60 Mb. Than you have three options to share:
By creating a file server, uploading to skydrive or saving it to a phone music library and than usual way of sharing files with pc. You can try this app without paying. I'm not shure if it is stable on gdr3 as I'm waiting on my official update for Lumia 920.

Free version fails in long recording, it doesn't even show last recording.
Yovisoft is only the working one. But strange format and size.

Try Wavepad Sound Editor. You would be able to trim any unnecessary parts and when you save it, you can set the bitrate that you want it to be.

There was an update to Instant Incognito Recorder that adressed some bugs (crashes, etc), you can try it again and see if it works, also the dev. added an option to save to music collection so you can copy recordings via USB cable.
