Wizard Speed Question

Why is it that an ipod with a dual 90mhz processor can run high quality video at higher framed per second than a wizard that runs a dual 200mhz which can be overclocked to 264mhz? video on an ipod really beats the quality of video on a wizard. just a silly question that just wanted to know.

I'm pretty sure the iPod video has a dedicated video decoding chip that deals with MPEG4/H.264 encoded streams, so the 90Mhz processor doesn't really do much at all when it comes to decoding the video.

What application are you using to playback video? I use TCPMP to watch various video files without any problems (MPEG, Divx). The included Windows Media Player is pretty terrible in comparison. The Wizard will choke on high bitrate and large-sized videos that aren't scaled down to its native 320x240 res. You have to remember that the 200Mhz processor in the Wizard is a general CPU. It's a multitasking processor geared for non-specific tasks, whereas the iPod Video CPU has been designed from the ground up to handle dedicated audio and video. It's not a fair comparison to look at just the amount of Mhz each processor is running at. For what the Wizard is capable of, it's really a nifty device. Although, I wouldn't mind more horsepower either. :wink:

well i found what it was, ipods use the mpg format i think which runs very crisp and clear at high bitrates. the wizard can handle mpg formats crisp and clear too! the only downfall is how much memory it eats on my storage card. the windows media format sucks at handling high bitrates and gives out ugly results on videos. so im going to download my music videos in mpg format from now on . its quite fast and clear exactly like an ipod. thanks to all the replies above. it was really helpful.

Smooth video that is also in-sync (seems a tall order for the Trinity)

Hi
I have an Orange SPV-M700, running the original WM5. Try as I might I am finding it difficult to get videos to play without dropping frames and often the audio being out of sync.
I know that the bitrate of videos makes a difference, and if I use very low bitrate videos admittedly the frame-dropping reduces. However, I am basing my results on the fact that I have owned several PDAs and the SPV-M700 is the latest, with the 400hz processor and yet it plays videos worse than any previous PDA I have owned.
I am testing using the same bunch of videos which played absolutely fine on my XDAIIi and also on my old HP4150. Software I am trying is TCPMP (7.2), Pocket TV, Windows Media Player 10 etc. I have performed exhaustive tests with almost every configurable setting each player offers. But whatever I try I find the video performance of the SPV-M700 disappointing and considering it has a fast processor I am very puzzled.
I have even tried three different makes of SD card and that seems to make hardly any difference. Do you think that the SD cards are not reading quick enough on this device, as surely the processor should be able to play videos efficiently?
I gather that TCPMP (which has always been my favourite media player for the Pocket-PC) doesn't properly support the Imageon chip - does the Core Player that you have to purchase work any better? - I believe that it comes from the same background as TCPMP.
I would appreciate any input or thoughts, and what your experience has been like with videos on the Trinity. It's really bugging me. I don't want to have to encode all my videos at lower bitrates - it's taking a step backwards and I purchased the SPV-M700 as an upgrade, not a downgrade!!!
At the moment, although it's bulkier, I am starting to think I'd be better off sticking with my XDAIIi and dumping the SPV-M700. I say this because I have also had much frustration with the well known Mini-SD card compatibility problems that the Trinity suffers.
A beautifully sized device like the Trinity is sadly let down by these sort of issues.
Thanks in advance
Spivvy.

Well, I had no problems with playback at all.
I use MPEG4 video at 512-640 bitrate with AAC audio at 96 bitrate all in a 3GP container. With these settings I get crystal clear results.

Hi OrageSpiv,
Before i used to own a Hermes that had a bad issue with it's imageon chip and TCPMP and Coreplayer (early versions). I paid something like $20AUS and it not only solved the issue on my Hermes but increased the perfomance so when I benchmarked my 320x240 512kb-Divx 128kb-mp3 movies to run on 300%-400% average. I tried it on my new Trinity 3600i and it sores along at 400% + I think since you have a 400mhz processor your perfomance will be similar to what I got on my Hermes Samsung 400mhz processor. I'd strongly recommend getting their newest version instead of the TCPMP betas.
Hope this helps.
Regards,
Slither2006.

Hi Slither
Many thanks for the reply - that's exactly the sort of information I was looking for. I know that I could lower the bitrate of videos etc but I am more interested in playing videos that used to play well on older Pocket PCs.
I will consider buying CorePlayer and I will let you know how I get on.
Thanks
Spivvy

Hi
Well, I said I would get back to you if I decided to purchase CorePlayer. Slither's post was encouraging so I purchased CorePlayer and I can happily say that my initial tests are very good.
I have tried playing some of the video files that were not running as well as I had hoped and they play smoother, with fewer dropped frames and better audio sync than they did previously with TCPMP, MediaPlayer, Pocket TV etc.
The above findings are without changing any of the default settings within CorePlayer so I reckon there may even be scope for further improvement.
At the moment I am a very happy chappie - it's early days but the signs are good and I already feel that I have a better video player on my SPV-M700.
I'll report back later when I have made more tests etc. If any of you have had similar experiences it would be good to share them on here.
Cheers for now
Spivvy

Hi OrangeSpiv,
How was yr coreplayer testing so far? r u manage to play DIVX movie smoothly using this software? I recently bought a p3600i but experincing the same problem you mentioned earlier. Trying to play divx movie i downloaded such as "Heroes" using TCPMP 0.72 but experiencing the lose of frame rate (lagging). Any other software which can play divx smoothly on our 3600 ? Thks.

Slow video playback?

Hey all.
So the HTC Touch Diamond has a VGA screen. How can I get it to play VGA quality videos? or is this not possible? I would of thought it would be with its own graphics processor and decent cpu. I have tried .mp4 at 512kbits 640x480, but struggle more than 7 or 8 fps. It works good enough at half the resolution, but is still dropping some frames. Not as good at video playback as some reviews would have me believe.
I am using TCPMP , which has been modified to work with Windows Mobile 6.1
Many thanks.
Gary.

Well, I have played some movies that have higher resolution than 640x480 with -very- smooth framerates in CorePlayer (easily over 20 fps).
Specifically: HellBoy Sword of Storms, Eagle vs. Shark.
No problems at all.
HTC Touch Pro.

Yep, i have high res files playing in coreplayer as well (touch pro). coreplayer doesnt fully support diamond (or touch pro) so it can only get better in the future

Taken from Coreplayers site, this looks good:
GPU support: Intel 2700g, ->ATI Imageon<-, QTv, Marvell Monahan Processors
CPU Support: ARM9, ->ARM11<-, MIPS
Both the processor and gpu will be used really well on our diamonds/touch pros.

coreplayer works fine for me in vids much higher than the screen res, you must be doing something wrong or that "hack" to make the player work in 6.1 really isn't a good idea

Ok, thanks for all your replies. What format are you using to get decent fps with Coreplayer, and what bit rate normally?
Its a shame coreplayer do not have a trial version, so I want to be pretty certain first that it will work.
TCPMP hasnt been developed for a few years i dont think so that might also not help.

Well i splashed for Coreplayer anyway, but I still get rubbish fps
.AVI (xvid) 640x480, 24fps, 748kbits.
Am I using the wrong codec?

24fps!?
That's supposed to be quite good (100% for most movie rips).

Using Coreplayer, VGA .avi videos play very smoothly on my diamond as long as I'm not using A2DP. Once I pop on my Jabra BT8010, the high res vids start to skip a little. I hope Coreplayer fixes that up soon!

Hmmm, could one of you do a favour please?

Download the PSP version of the trailer, and then try to play that on your HTC Touch Diamond. It won't even play that for me Then let me know if it works fine for you or not. I get alot of tearing and skipping. I have gone as low as 640x480 avi at 512kbits and its still jolting around and skipping. I have used all the different types of rendering, and currently have Coreplayer 1.25
Not the good playback I was expecting
Thanks
Gary

After some tweaking around with the bitpool and some searching, I've gotten the A2DP performance hit down to a minimum.
Bitpool: 58
Maximum Bitpool: 80
That seems to reduce the stuttering when playing VGA vids using coreplayer. They still stutter a little during some demanding action scenes when using A2DP, but the stutter is much better and the audio and video are in sync.
Once Coreplayer is optimized for the Diamond, this thing is going to scream!
Overall, I'm pretty impressed with this little phone.

What version include this ?? or is just for a future version ??
And what is the GPU that comes with diamond ?? that "ati Imageon" ??
TY

So there are no video apps that are currently programmed to use HTC Touch Diamonds fancy bits? like the graphics processor etc?

use the divx labs divx player!!! lol

OK, I did what you said and I ran the video in Coreplayer benchmark mode. The best I could get was 70%. Perhaps it's the h264 format that is so demanding?
The more I use the Diamond the more I get dissapointed.

Hi, I'm having the same problem on my Touch Pro (i'd post in the TP forums, but no app/software category there), however I don't have Core Player because I won't pay for something if I can't see if it works first.
My question though is: Are there any similar movie file players like Core Player that are free?
(sorry if this was a bit off-topic, and I've tried searching but did not find anything useful)

If I see correct, madagascar is h.264 coded. It's a codec that is used to prepare hd video(b-r,hd-dvd etc.). It needs a powerfull processor or a hardware acceleration from graphic card. Some of new computers have problem with decoding it (i.e. with embaded video chip) and you're trying to play it on diamond. The 70% you're getting is a great score.

I have Coreplayer v 1.1.0 Build 1408
I get some lag for my music videos I have on my phone.
File Size: 78,924KB
Video Size: 640 * 480
Frame Rate: 29.970
is there a reason why it's laggy?

Why don't you try the latest build which is v1.2.5 I believe.

Just updated and still has the same problem, maybe it's the file that is the issue.

Improving Framerate of Coreplayer on Xperia

is there any tweak or setting to improve it?
due to the TyTN II driver..it does play videos good and not need to re-encode..just drag n drop n play.
but i noticed the framerate is still not good enuff ..if it cud be improved..it wud be the perfect portable DVD player in your pocket.

i also noticed in Portrait mode...framerate is higher than in Landscape mode.

Lower the bitrate of video and audio until it's acceptable. I have a specific one I always using when re-encoding files. I'll have a look later if I remember

Ways to improve framerate without having to convert the videos? Converting takes up lots of time. For shows like 24, the X1 does not play very smoothly

X1 is using cpu to decode movie, so overclock cpu will speed up the coreplayer playback performance,hehe...

so i guess only solution is to convert the videos like u have to do for iphone/ipods?
kills the fun...because i dont have so much time for conversion..and whats the point when u waste more time on conversion than watching the show itself

im using coreplayer and it runs around 22-24 fps

[Q] Android Video Player?

I cant seem to find a single video player in the Market that plays a range of formats, primarily wmv and avi that I have downloaded.
Any suggestions?
I have to make the commute to work a little more bearable since I broke my Sony e-reader...

i know that the 'rock player' plays avi and mkv files, have you tried that one?

Thanks for your reply, I just checked out rock player and it doesn't seem to work.... opens the video for a split second before closing it again...
I guess I'll keep looking.
Any dev looking to port VLC over to android?

oh thats strange, it works on my hero (they have different versions for different devices, make sure you downloaded the ARMv6 one)
but tbh its not great because theres a lag between the video and the audio, most probably because of the hero's slower processor. i'm looking for a good video player as well

Hmm.. Rock Player started to work by itself.. kinda.
Plays the video for about 15 seconds (very choppy, even after all tasks killed and using a blank Sense Scene) and then freezes the phone, have to remove the battery..

Have u overclocked?
My hero wouldnt run RockPlayer on 691MHz as MAX. Had to down it to 652.
in the end i deleted it, since the video was choppy. i guess the processor just isnt up to handling large video + i hate ruining films on a small screen.
there are some forum posts on VLC Forum about porting to Android... i think the conclusion was that it wasnt going to happen?

My phone is indeed overclocked, to 672Mhz.
I'll try messing around with the OC settings and see if it makes a difference.
I know the processor is *only* 528MHz (stock), but I remember watching videos perfectly well on my Packard Bell 166Mhz, 32mb RAM, 2mb Video card pc...
I think Android should be doing a LOT better with with handling Video, see my post in the "Android 2.3?" thread...

There is a significant difference between the low quality avi files of the past and the h264 mkv content of today. Some of the recent files require a minimum of a 2GHz processor to run (understandably 1080p content, but still). And lets not forget about the instruction sets which provide desktop cpu's with a boost in those areas. Furthermore, considering your phone only has a cpu and no dedicated or otherwise gpu it isn't all that surprising.
Even running an average quality dvd rip avi file my CPU is running at between 15-25% and I have an overclocked dual core 3.33GHz intel cpu E7300 (25% is roughly 833MHz). Not to mention GPU usage, which at this time I can't be bothered to record.
I understand that this is not definitive evidence but I am using it to show that you are simplifying the problem. TV shows and movies that are ripped now have much higher quality resolutions and bitrates than those of the past, it is not surprising that they require higher processing power. Realistically a 528MHz low power phone cpu is unlikely to be able to keep up with these improvements. Just like the low power Intel Atom desktop chips fail to run 1080p video (even the dual core one) running somewhere in excess of 1GHz (think its 1.6GHz).
That wasn't meant to be such a huge rant...

HAHA! I know I totally simplified it but I guess I was just trying to say that a smart phone in 2010 should be able to handle video with no problems...
My upgrade is due in January, so new handset here I come!
Will be funny to see the (still awesome, despite my rant) HTC Hero become my backup phone...
