Coreplayer Audio

I've set my Coreplayer up as per the posts elsewhere in the Athena threads and the video quality is almost perfect now.
I'm using 320x240, DivX 6, 500-700KBps constant bitrate files.
Stereo MP3 audio. 96kbps or 128kbps.
After 10 mins of playback the audio slowly starts to lose sync (it plays fine on my PC).
Has anyone got any ideas what I need to do to stop the audio from losing sync?
Any help greatly appreciated.

hi
when you say "outof sync", does this mean that the audio is fine but the video is not "in time"? if yes, that's exactly what i was going to ask in the forum =) but i'll be trying the parameters you set. i've been meaning to ask the "optimized" setting for this application.
cheers

Yep, that's exactly it. It starts off fine, then ever so slowly the video gets ahead of the audio.
I've 'fiddled' with just about every setting I can think of within Coreplayer but have yet to find a solution.

well, at least your video gets ahead. for me it's the other way around...the video is late yet the audio sounds perfect =)

ive already asked this question. with no replys. ive tried every setting and format possible. still loses sync. it doesnt matter if its from the sd card micro drive or streaming. it still loses sync. ive even tryed disabling the auto scaler and running tcpmp over clocked. still loses sync. im a a loss. if you find a solution let me know.

I guess we need to wait for the next version of Coreplayer which will (hopefully) be released on the 18th of June. It supposedly fixes some of the ATI issues.

I am so sick to death of this subject!! Not mad at you guys, but at ATI/AMD. This has been an ongoing issue since September last year when the TyTN was released with the ATI Imageon chip, and due to no input or support from ATI/AMD, Corecodec cannot fix this issue as it's to to with the Imageon hardware.
Bottom line is find the settings that work best for you. For me, I find TCPMP v0.72RC more stable and versatile than CorePlayer v1.04. Also set Video driver as Imageon (NOT Imageon decoder!) this yields best performance and visual quality 'during' playback.
If you're using DVD-Rips use the above setting, but if your playing/stretching QVGA 320x240 on your Athena, then Rawframebuffer mode is even more stable in the GUI, but lacks the ooomph of the Imageon driver, which to some extent might well eradicate your lipsync issues.
One more test folks. Play your video whilst your Athena is pluggen in to mains power. See if the lipsync is still out. If it is make manual adjustments in the A/V offset in TCPMP under Advanced.

How cam that you can use it.
I'v tried 0.72 version as well as 0.81 and both give me the "crash.txt" error while starting TCPMP.
Oh, you are using CorePlayer not TCPMP, right?

im using coreplayer the latest version becuase tmcp as you said keeps on crashing, (for me too).
With a hard reset playing even a video in windows media player still gives a audio lag. Its so bad, now i don't care about quility just let me have a video with audio i don't care how bad the video looks like.
Does anyone have any solution? ive tried all kinds of "video output" settings and it still gives audio lag (even raw framebuffer)

FINALLY! ah found it after lots of searching of google and forums and sites...
its -400ms and its perfect thought the whole video..
(Note: the best method that i use to see if its in sync is to watch a lecture and then watch their mouth real careful and you'll see that -400ms gives the best results )

What is this -400Ms?

-400ms is -400 milliseconds as in time. The minus sign means "start playing the video 400 milliseconds ahead of the audio. Its perfect for core player put all the settings on max just take acceleration and dithering off. And it plays a DVD rip perfectly no conversion very sweet on its 5 inch screen
If you don't know put the -400 in the settings next to "manual A/V offset +/-" and just type in "-0.400"

Does it play flv files as well?

Coreplayer plays flv files, yes. There's no need to separately install additional component. It benchmarks better than TCPMP in my test.

Graphics performance, QTv

Good afternoon!
I have the following problem: performance of my screen graphics while in full screen (ie movie, games) is rather slow. I have CorePlayer installed and it has a major FPS drop when there is a fast picture change in a movie. I've increased alot buffer allocation and put some settings that could ease the situation. I should note, that it happens only to movies that are not encoded before transferring to phone (they remain as is).
Also, I am unable to use QTv option as it gives me sound output only and my screen remains black.
Experience pretty slow graphics in games too.
If you could help me a bit with this problem, I would really appreciate it!
ROM: R2AA008 UK, but had same problem with previous version (R1AA017).

Good Afternoon,
please make sure you read one of the many many threads on this!
coreplayer DOES NOT support hardware playback on our devices at the current time..

Thank you for your reply.
I did a research already and all I found was that there is expected to be "better" support of QTv in v 2.0 of coreplayer. I assume better means that it is still working on current version.
Anyway, QTv is just a mere problem. The main problem when using any other type of video drawing, ie DD.
Also, I did not find much information about having slow graphics on X1. All I found were tweaks (some of which I have applied) and general performance issues, which I don't have.
If you would be so kind to address me to the right topic where the solution/discussion was mentioned, I'd appreciate it.

Best playback now is to convert the video into mp4 using HTC HD convertor (easy to find here) .. and then to play it in media panel or WMP. You can play movies in 800x480 totally smooth like that.
Second option is to use Core Player 1.3 with qTV .. but you will rarely find movie which will play at 100% with no conversion. Anyway CorePlayer is lot slower, which is easy to compare if you let it play those mp4 which play great in WMP.
Then there is TCPMP .. but that will hardly play anything any good.

scroll down or press page 2 (or maybe even page 3 as repeated threads like these push everything back) and you'll see there's at least two threads started by nawfalah, from the last week.

Managed to enable QTv support without decoding.
Thanks for your replies fards, Dr.Sid.

Still give it a try. It's really much better with conversion.

i use itje's touch-it 3.5 rom and im using coreplayer and i havent converted a dvd-resolution movie and it runs buttery smooth on my x1. its file type is .avi

Video, What am I doing wrong.

I have tried several trials on video converters and no matter what I do I get great picture but the voice is way behind.
How do I get the voice to catch up with the film. ( sorry I know it is not techy language)

I use MediaCoder to transcode video. It's free.
http://mediacoder.sourceforge.net/
The even got the iPod Edition which u can use for simplicity reason.

Thank you, can you tell me what settings you have used on that programme.

Core player, THE best media player you can get imo.
Will even play .mkv!!!

He is talking about encoding the movie.
You can try Windows Media Encoder (from Microsoft).
It's also free, and does a good job on encoding movies.

hi guys,
i seem to be having the same problem with the whole audio and video out of sync. i have tried a range of format eg. wmv, mp4, 3gp etc but all are about half a second out of sync. i have even tried core player and tmpcp but with no luck. did anybody else have this problem and manage to fix it? any help will be much appreciated

Hello,
I use the HTC Touch HD Video Converter which is very good. He is especially for WVGA 800 x 480 screens, and the quality of the movie is very good.
HTC Touch HD Video Converter v1.21

DVDFab6
I have not (yet) seen the problem with the sound you describe here.
I use DVDFab6 since a while, originally to convert videos to my iPod, but now also to my HD2.
I have a Touch Diamond too, but the screen is a bit too small to watch for longer time and it drains the batteries also very fast. I haven't tried yet fully, but my first tests show me I can do 3-4 hrs of video on one battery and still have enough power left to use it as a phone. Which is very useful if you have to do a lot of short flights.
I use the PS3 settings in DVDFab6 and adjust the display to 800x444 size, depending on the original size. I found that I can not play them directly from Mediaplayer, but if I click on them in the FileExplorer they start playing without any problem.
BTW, also the iPod m4v files play nicely without delays on the HD2

Yeah i have the same problem, the video/audio file is perfect on my pc but about half a second out of each other on my HD2. You can adjust the audio/video sync in core player but it shouldn't be happening in the first place.

hi guys, thanks for your help. i called htc tech support but all they were able to say was perform a hard reset, which sadly didnt fix the problem! even mp4 videos downloaded straight from the net have the same problem. such a shame because apart from that its an amazing phone. will keep trying and post up if i have any luck

I just tried the one that Braakie suggested and although it converted my 700Mb AVI film to a 500Mb MPEG 4 film, when i tried to copy it to my SD card on my HD2 it said the MPEG 4 format wasn't supported. Can someone enlighten me as to what formats are supported and/or what movie player they use.

I'm having the same audio sync issues as others here. I'm encoding using handbrake and when I play it back on the PC it is perfectly in sync. However when I play it back on the HD2 using the HTC video player the audio lags slightly but noticeably behind the video. When I copy it to my wife's Touch HD it plays fine, so it seems to be a problem with the HD2 software.
I'm running the stock Vodafone 1.43 ROM with all hotfixes applied. Will a ROM update fix this? Anyone else with this ROM having/not having this problem?
I'd be very grateful for any input.

Chaps,
Somewhere on XDA is Chainfire's video driver update (or a reference to it) which you should find and install to help overcome the lip synch issue.
If you can't find it using Search...http://www.google.com/advanced_search?q=+site:http://forum.xda-developers.com&hl=en&lr=&as_qdr=all then go onto the Modaco site and its there somewhere under the Toshiba TG01 device.
Good hunting.

Thanks for your help - I've found the driver here:
http://forum.xda-developers.com/showthread.php?t=592663
However, as far as I can see that's a 3D OpenGL driver and not something that I would expect to affect video/audio synchronisation. Unless, of course, you had the same problem and this fixed it for you? I don't really want to mess about with video drivers unless I'm sure it will fix it.

I was a little dubious and cautious myself but installing the driver did seem to make a difference, sufficient for me not to notice it as much.
Installation is a personal choice. You might want to make a full backup of your device using, say, SPB Backup, before you install. That way you can do hard reset and restore if you don't like the driver.
All the best,
WB

I have the same problem with youtube vids too, just had a replacement hd2, but it's just the same, skyfire, coreplayer, youtube you name it, audio lags the video...
Real pain in the butt for a device who's main feature is a huge screen...!!!

Well I installed the 3D driver, which was easy enough, but unfortunately it made no difference at all to the video/audio sync in either of the two driver modes so I uninstalled it again. (No need for a hard reset, thankfully). I'm using the video in this thread to test since you can easily tell whether it's properly in sync or not.

Oh well, it was worth a try - thanks for the suggestion.

Xvid / DivX etc video playback

Hi all,
Looking to use a HD2 to watch xvids / divx's while on the train. Realise this will (most probably) kill the battery etc. but in some situations (when there's a power source at destination!) it seems a good way to kill time to me.
Any recommendations on the best player for such? Previously I've heard good things about Coreplayer.. although it seems not to be so good on this platform? Alternatives?
Thanks in advance.

Basically, if you want support for as many formats as possible, Coreplayer and TCPMP are the way to go. Coreplayer pefroms fine on HD2, even without supporting the graphics card capabilities, merely because of the powerful processor. About the only real-life limitation I've encountered with it is lack of AC3 sound support. For AC3 you can use TCPMP. Its UI is ugly as hell (in fact it's so ugly that I personally prefer not to watch movies with AC3 sound at all) but it does the job.

if you go for coreplayer be sure to set it to GDI and smooth zoom in video settings to get the best possible result

strange one that because i would recommend raw frame buffer!
probably depends on what media you're using?

Both settings will work.... but that also depends on your content. Best practice for the HD2 (and in general) is to do benchmarks on that content with each video output setting (GDI Vs. Raw Framebuffer) to see what works best.

Just an extra footnote, I'd recommend searching for TCPMP version 0.71, as the later v0.72 (both RC versions) wouldn't even run for me!
I use TCPMP to watch films on train journeys, and can get a couple of films watched and use about 60% of the battery. So yeah, it's a drain, but not too bad.

Divx Player Mobile
http://labs.divx.com/MobileCommunity

Hopefully this thread will work and not trying to hijack.... I've tried the included WMP and CorePlayer and cannot for the life of me get any video to playback on my HD2. I've tried stock xvid, wmv, etc. The closest i've come is sound but no video. What's the trick????

In CorePlayer, go to Menu - Tools - Preferences - Select Page - Video. Change Video output to GDI, Raw Framebuffer or DirectDraw (I'm not sure which setting will yield best results, but you need to disable Qtv, it doesn't work).

1.48 ROM?
Thanks for all the above advice!
I had Coreplayer working fine, playing two Xvids I had on the storage card well with either settings.
I've now upgraded to the 1.48 ROM however playback now seems to be stuttering badly (same two files). Might be just one of those things as I've messed around a little with install apps etc, so need to do a hard reset this evening and give it another try, however yup just want someone else to confirm this by saying they are having good success with playback via Coreplayer on 1.48 ROM..?
Cheers.

Re. the above - are these the only 'optimum' settings I need to go for? (withstanding the debate over GDI vs. raw etc). For smooth zoom should this be On or 50%? Anything else?

Core player problem...

Hello guys. I installed core player and I am trying to watch a video but, I don't know why, the playing is very very slow, with the software displaying many times the icon of "waiting status"... unwatchable!
If I try with in-built windows media player the same file is good and smooth...
the file is in .mp4
I also try divx player, but the GUI is very small and the buttons too small...not good for me.
any ideas?
Thanks a lot to everybody in advance.

More information please - what version of Coreplayer, what settings?

if wmp is playing smooth then why would u need coreplayer! if u wanna watch flash from browser....get skyfire.

sorry for few info, but i was in a hurry.
Core player 1.3.6
I have installed also the driver patch 1.1 by chainfaire (if it is related...)
My rom as in signature.

Go to Menu>Tools>Settings>Select Page>Video and then change the Video output to GDI. That should fix your performance issues.

THANKS
thank you jakem.
Now works perfectly. There are a lot of settings and I don't know exactly what they are. Unfortunateky I haven't found yet a manual on the net
But anyway, great software. I managed also to rotate landscape with BsB the software. Did I do it right or there was a solution inside coreplayer? (because sometimes it gets slow with few framerates)

There is setting for rotation. It's in the main menu .. take some time experimenting.
Actually I found that raw frame buffer video mode is a just few percent faster, but I may just imagine things.

I'm having the same problem. Videos stutter until they are unwatchable.
I opened the same video in WMP and it runs without any lag.
I selected GDI in Core Player and still the same performance continues.
I have the ChainFire driver installed, would that be related?

This happened to me yesterday.
And ironically, the benchmark was ok! only the playback was horrible. Couldn't find out what caused it. I removed Chainfire's patch but that didn't help. Had to hard reset at last.
And by the way, I tried all 3 video output modes, no avail...
Coreplayer 1.3.6
