WMV lag problem - Touch Diamond2, Pure Q&A, Help & Troubleshooting

I find that Diamond 2 has lag problem on play back some WMV format media.
For example, ORB, I did tests on Dell V51 (updated to wm6.1), Atom O2 (WM 5.0) and Diamond2 with Bandwidth limited to 160kbps from WIFI.
Both O2 and Dell works fine. However, Diamond2 has serious lag problem.
I increased the bit rate from 160kbps and 320kbps, it did not improved anything on Diamond 2.
I also find some WMV file storaged in memory card has similar problem, while it does not happen in neither Dell nor Atom.
I doubt Diamond 2 has problem on play back WMV.
Anyone has similar experience?

I haven't tried many wmv files yet, but video playback is somewhat bad if you dont convert it to mp4 (H264+AAC).
So have a quick look here: http://forum.xda-developers.com/showpost.php?p=3830181&postcount=11
If you have to use WMV then reduce resolution, framerate or bitrate.

Did you try test of CSPAN from http://test.orb.com/streamtest/wmp.jsp?
It seems that it is ok for playback of CSPAN.
If I connect to my ORB server, however, it lags seriously no matter how low bit rate it is. It does not happen in Dell or Atom.
Therefore, I doubt Diamond 2 may have trouble on some WMV encoded format and its WMV implementation may have bugs.

video playback, cpu to slow?

I replaced my qtek2020 (400mhz) with the tytn2. With my qtek i was able to play almost anything (divx with high bitrate, vcd files, streaming 800kbps video over activesync) . The tytn2 seems to be to weak to play these files.
www.streamingpda.nl --> humortv (800kbps) stutters.
Divx --> without reencoding stutters.
Does anybody know a solution, please help, its the only thing i am dissapointed in with my new baby.
thx
anybody?
Ok, maybe no one has a solution but can somebody confirm that he has the same problem?

I went to the site you reproted and saw the same problem. The video seems to play ok for about 20 seconds and then goes in to a jerky frame mode. The sound is still clear though.
Oddly, I went to the windows media site from the windows media player that this site seems to demand and watched some clips there that played flawlessly.
Might it have to do with the way your site is encoding their stuff?
I am a noob but the windows media player offers almost no options to fiddle with to try to make things better. How to force the video to play with TCPMP?
I tried windows media player (not a lot of options indeed) , tcpmp (the latest version) and Makayama liveTv. They all sem to have the same problem. It is ok if the bitrate is below 500 kbps. I am giong to try that windows media site.
I'm having the same problem. As the video plays it will skip parts of it. but as you say the sound is fine.
have you tried setting your video driver to GDI? i would think that would solve the problem
How do you do that?

In TCMP: Options>Video>GDI
Oh Ok, I tought you know how to hack the WMP.
I use CorePlayer (and TCPMP) and I use RawBuffer ... Works fine (faster than WMP).

GDI or Rawbuffer?
what does GDI do?
so we have to use tcmp? wmp is useless if we want some kind of quality or flow? What the hell were you thinking HTC? give us some new drivers that works with wmp! allways a guinea-pig.
Posted this in another thread, but it applies here as well.
I'm using the Core Player and I tried "GDI" vs "Raw Frame Buffer" and the benchmark tells me;
GDI=Ave Speed of 135%
RawFrameBuffer=Ave Speed of 168%
Guess I'll stick with Raw, it plays my Divx vids perfectly, but I encode mine at 320x240 just for small gear like this and iPods. They look very sharp and clear at these modest rates.
I also tried RawFrameBuffer with the Keyboard Open=163%
So is my TyTN 2 worthless for playing back h.264 videos ?
I'm trying to playback the DL.TV podcasts in native ipod video encoded .mp4
It is already formatted 320x240 at under 400 kb/s w/AAc audio...
The sound plays fine, but the video stutters along.
Benchmarking only comes up eith 58%
Do I need to fix the settings ?

I am using TCPMP 0.72
I have tried both GDI and Raw Buffer with no noticeable difference in quality.
Both stutter along on that video.
Is there a web pae or post with the correct option setting for all of these other sub menus ?

What video settings work (all rants off please :) )

I think most of the active members are aware of the video difficulties SO please (please, please) turn your rants off for this thread. What I am trying to find is a combination of settings that DO work.
My preferred codec is MP4.
From some suggestions in other threads, I have tried these encoding settings.
Screen resolution: 320x240
Frames Per Second: 30
Kbps: 300
Audio codec: [email protected]
...and I am playing back on TCPMP 0.72RC1 using these settings
Options/Video: Raw FrameBuffer
Options/Video/Dither: Off
Options/Video/Pixel Aspect Ratio: Auto
Options/Settings/Advanced/Slow Video Memory: On
Options/Settings/Buffering/Preload at Underrun: 85%
Using this, all I get for video is about 1 frame every 3 seconds. Audio is fine.
So can anyone add this this for getting MP4 to work?
Do I need to use a different codec? If so, I would prefer something other then AVI, since I have a mixed environment. Does anyone have suggestions on the best cross platform Codec, that has work well on the Kaiser?
I'd be interested in this too. I can play back videos taken from the video camera flawlessly but when trying to encode them to the same MP4 codec they can get choppy. Not sure what gives :0
Using WMV here
I couldn't get the mp4 output from my ATI Multimedia Centre software to work at all on my TyTN II so I've settled on WMV 9 at 352 x 288 resolution and 372 kbps (thats at 15 fps). Anything with higher bit rate than that seems to cause problems with to much screen tearing during fast movement scenes.
You might want to follow this thread... seams that the Core Player is attacking this known problem for the Tilt. I'm by no means an expert on this, but seems like the Qualcomm QTV technology for the video has some issues:
http://www.corecodec.com/forums/index.php?topic=596.0
I use PDXE, Lathe, and a few others to encode Divx videos at 320x240 video quality at "28" audio in stereo at 96 or 128k MP3 with a total bitrate under 500k (usually shoot for 475kbps). If the encoder allows it, for portable video I bump the audio volume by 15% and I increase brightness as well. To me most movies look darker on the small screen. If cropping is allowed I crop widescreen content, cutting off some of the sides of the picture to get closer to the 3:4 ratio of PDA screen. I also like to turn the brightness down as much as possible to increase battery life so the bump in brightness helps there as well. An average movie 1:50 length is about 480MB
I've used Core and TCPMP (currently using TCPMP for the youtube capability) and use Rawframe buffer as well. I'm sure that Core 1.2 will make things even better.
I get 30FPS and normal fluid video, looks like my other 8525, hx4700, and Archos 320 and 400 units with crisp clear video, no complaints.

There's lots avout video formats in the wiki here:

FWIW my mp4s recorded on my TyTN II wont playback on my PC either, it's simply a case of finding a suitable codec.

Hey thanx for the reply but VLC is what i got installed and doesnt work, thought someone else had the same issue like mine. The .MP4 files that the TiLT records doesnt playback properly. PROBLEM is : I get the video portion just fine, but no sound. I have the. I tried in Media Player, VLC, QuickTime, RealPlayer, etc.... All the same... video plays but no sound.
I googled the issue and found out some other HTC phone users got it too and a couple solutions i found are.
1. In QuickTime it says: "Error 2041 - Invalid sample description in movie"
Solution: Checked the Apple.com or quicktime forums, if you use quicktime, change the file name from .MP4 to .3GP and it will work, it will not work otherwise. (if you dont know how to rename the files or dont see extension, Windows vista or XP go to tools>folder options>view>uncheck hide file extensions for known file types and voila)
2. Since I did so much reading on this, I got a new player (KMPlayer) that beats vlc in my books it plays the files recorded from the tilt just fine unlike VLC latest build, its fast and does all vlc does but it has a better GUI and plays anything you throw at it. you can get kmplayer here
Conclusion: The TiLt is fine, just that I couldnt get the right player to run the video files it records. apparently there is some issue with the qualcomm processor and the video output files of .MP4, some others have reported issues with any .MP4 files and had to do the same listed above.
Hope this helps someone here...
if you want an mp4 player on your pc for free, go to nokia.com

MANY THANKS! zulualpha7,
I have had the error 2041 problem for a long time and have never been able to play vids recorded on my TyTn II on my PC.
I almost installed various codec packs as other forum members have done but after reading about potential problems of having multiple codecs for same file type and upsetting the system I decided not to do this.
I have some really important 'once in a lifetime' family moments like my friend's son catching his first fish etc... I though they were all lost for ever.
I just downloaded latest Quicktime and renamed file extensions to ".3gp" like you said and now I can watch everything!!!!
Thank you so much this really has been a big improvement for me.
ONCE AGAIN THIS FORUM ROCKS! Thanks to everyone for so much fantastic helpful info.

Is there any way to get large videos to play @ full speed?

I second that Especially the new Zune is really nice. You can connect via your router to sync your music. I just hate the zune syncing software it's such a pain in the ass. I wish we could sync with WMP. I mean come on seriously.
Pocket Divx encoder
I had the same problem with my touch. TCPMP would not play large video's .avi even though it supports it. I used Pocket Divx Encoder to reduce the .avi according to my screen size and now I can watch any .avi without any problems and the audio and picture is still incredibly clear. I max out video and audio quality still with no problems during playback.
Pocket Divx Encoder is free
Hope this works for you and enjoy your video's
I use CorePlayer (based on TCPMP ) to play my Divx files (700 to 900 Mo each resolution 660*360, datarate 1010kbps) without any specific Mobile transcoding and it plays quite well with the right settings, with some rare glitches (but i guess it will never work flawlessly until we have the real Kaiser drivers).
TCPMP is good, but Coreplayer is faster on the Kaiser from my own experience.
The only down side about Coreplayer (aside from the fact its not freeware) is that it cannot play AC3 sound unlike TCPMP (due to open source licence)
why i dont understand it...when i had my standard att WM 6.0 rom that came with my tilt...i watched avis and mpeg4//divx movies CRYSTAL CLEAR....and thatt was with no htc ca driver or none of that ****. And now ive upgraded to WM 6.1..first duttys hybrid then L26 and now garmins...and each rom has the same problem...old tcpmps crash and when i use the repack tcpmp app and it works....i have SLUGGISH and chopppy fps when i watch avi movies and mpeg stufff. How is this possible with all the new drivers and such....it was crystal clear to watch movies with WM 6.0..but with 6.1 its choppy and ****ty playback? has anybody found a better fix for this other then converting the movies to sccreen resolution?
have lookedeverywhere for pocket divx encoder but unable to d/l it can anyone post please?
Try xvid4psp. It's free, fast and has enough options. I use MP4 iPod 5.0G settings for Kaiser.
thanks will give it a shot

Sorry, my previous post was meant to be reply to felixthecat.
So, to make things clear:
- XviD4PSP is not media player for PPC.
- XviD4PSP is software for converting videos. You can find it here.
- MP4 iPod 5.0G is just one of the format settings in Xvid4PSP.

I use Core Player for videos. Videos converted with XviD4PSP using my settings does not play well in WM player. You can try it with some other settings.
Here are my current settings:
- Format: MP4 iPod 5.0G
- Denoise/Sharpen: Disabled
- Brightness/Contrast: Disabled
- Video encoding: XviD HQ Ultra
- Audio encoding: AAC-LC ABR 128
I don't know what you mean with "bigger vids", but I use it for converting my divx/xvid movies and shows to MP4 and it works well. I think it supports even DVD files, but i didn't try that.
Last time i checked it took 6 minutes to convert some 30 minutes divx show to MP4 (Athlon X2 4000+, 2GB RAM, GeForce 8800GT).
One more thing about Core Player
Core Player with default setup gives me audio out of sync. But you can adjust that in options.
i tried those settings and didn't get a good result
works now i have upgraded coreplayer ... thanks alot

Slow video playback

Is anyone having problems with video playback?
WMV files they are played very slow (loosing a lot of frames). With MP4 I got best results but not the best. Any suggestions??
Thanks
WMV
I can't even get the above files to play
are you using Media Player? as video playback has always been awful on Medial Player on every pocket pc or smartphone ive everhad.
install TCPMP and video playback will be perfect, and will play any file you throw at it

Has anyone been able to play a full resolution file without skipping?
I am using CorePlayer now but if another player works better, please say so.
With Coreplayer I benchmark about 85%, which is not good enough.
I believe the Diamond should be able to get 100%.
I found that an encoded mp4 file would play about the same as the original avi xvid file...
What do you use to encode videos specifically for the Diamond?
Come on!! Post your results!

What video settings do you use with coreplayer ?
DirectDraw, GDI or what ?
This is what i get:
With these configs.:
But with some other videos i have i get only 88% speed and some frame drops and tearing.
Doesnt the Diamond has a good video hardware.
Imo, it shouldnt lag at all.
Ive read somewhere that it doesnt use the hardware correctly since the drivers were not fully implemented. Not sure if its true.
Still looking for a good solution... any more help?
Coreplayer is still choppy ...
Yeah, I wasn't able to get WMVs to play using this, either.
I think what we need to have a look at is which encoding, resolution, bitrate, fps, etc are optimal for the diamond using core player.
I'm experimenting a bit. Will report back in a bit...
I've just got my Ignito (diamond) a couple of days ago, but I've got a long history of video playback on hand helds. Since this is my first time post, and I happen to have a bit of time on my hands.... I'm going to convert a file into a series of different resolutions and settings to see which one will perform the best. I know the objective is to get a full res one to play, but I'll see what I can come up with.
Also, I'm using the default ROM at this time.
With Coreplayer you should use the 'QTv' display option - this is hardware accelerated and beats 100% benchmark on every AVI I have tried. If you get a blank display using this mode, you are using an old version and need to update.
Alright. After trying a bunch of different codecs, encoders, video and audio formats at various resolutions I came the conclusion that for now, full resolution video is just not possible without jerky movements during continuous motion or fast action scenes.
My eyes are very sensitive and I get really irritated if playback is not perfectly smooth.
So far what works the best in achieving this kind of natural playback is AVI as the output container with XviD video codec at 480 x 360 resolution, and mp3 audio. I set the video and audio bitrates to match whatever the source video was (min 864 kbps and max 1008 kbps for video and 192 kbps for audio).
Even then, CorePlayer is a must with the following settigns: QTv On, TytnII driver mode On and Smooth Zoom On.
Every now and again CorePlayer will show only a purple screen during playback when QTv mode on. At that point I usually do a soft reset and it starts working again.
This issue may be resolved with an upcoming release of CorePlayer (1.3) but until then, the solution above works exceptionally well.
I'd be very interested in anyone else is having success in other ways...
320 by 240 versus 640 by 480
I have done some playing with conversion and have found that the Diamond (currently) does not support the 640 by 480 settings with a good bitrate. The BEST conversion I have found (using Coreplayer to play back the files) is using the BETA Version of the Pocket Divx Encoder (http://www.pocketdivxencoder.net/EN_index.htm) and using the HTC Diamond Template (NON VGA!!!!, there is a VGA and non VGA) that team has developed. They have done an excellent job!
The output settings -
Dimensions 320 by 240
Video Quaility - "36" ... 584 kb bitrate
Hopefully an update by HTC or coreplayer will be released to fully utilize the resolution that the Diamond SHOULD be able to support, but for a clear, non jerky playback, this is my 2 cents
im able to play those axxo dvdripson using coreplayer without any sort of convertion....
I want to share my experience. I am using core player and trying to recode unprotected high-definition TV shows (original resolution of 1920x1080) that I've recorded on Windows Media Center (.dvr-ms files) to watch on my Sprint Diamond. Unfortunately .dvr-ms are poorly supported, and the only program I've found to recode is TMPGEnc 4.0 Xpress.
I am using Core Player version 1.2.5 build 4506, and my video output is QTv Display with the Tytn II driver mode enabled.
Like everyone else here, I have had horrible results when converting the shows to DivX at 640x360 at any usuable bitrate (above 500 kbps). Benchmarking in Core Player yielded a playback speed of 66% or so (completely unacceptable, obviously). So I played around with the resolution and bitrate, and finally settled on the following:
Format: DivX
resolution: 512x288 (maintains the 16:9 aspect ratio of the original)
Video bitrate: 850 kbps
Frame rate: 29.97 fps (progressive)
Audio: MP3
Audio bitrate: 80 kbps, 48kHz sample rate
With those settings, I have a 104% playback benchmark with around 25 dropped frames compared to several thousand played, and about 29.5 fps. Basically, it is completely smooth audio and video.
I was still PO'd that I had to sacrifice so much resolution and bitrate on a supposed media device, so I played around with other formats. WMV was awful. MPEG-2 was awful, and avi was passable, but no better than DivX. I also decided to try h.264 (MPEG-4 AVC). Here are the settings I used:
Video Format: MPEG-4 AVC (saves as .mp4)
Resolution: 640x360 (still maintaining the original 16:9 AR)
Video bitrate: 1000 kbps
frame rate: 29.97 fps (progressive)
Audio format: AAC
Audio bitrate: 96 kbps, 48kHz sample rate
Core Player absolutely choked on this. It was unwatchable, and the benchmark revealed a playback speed of 50%. Dropped frames were higher than played frames (!) and framerate was 13 fps. Obviously not successful.
But, before I deleted the file, on a whim I decided to try Windows Media Player and...it was completely FLAWLESS playback. Absolutely beautiful, smooth motion, no audio stuttering, slow and fast pans were the best I've ever seen on a WM device.
Why??? Is there something I'm missing about this that someone can elaborate on? Is this the fabled "hardware acceleration" that I've read so much about? I should note that WMP had a hard time on a 320x240 .wmv file, so I can't really understand how it is able to play a 640x360 .mp4 file so smoothly. In any event, I have found my perfect file format, and, surprisingly, it doesn't involve Core Player in any way.
-R
The thing is that HTC didn't release any kind of SDK for Diamond or Touch Pro and companies like CoreCodec have hard time trying to figure out how to use the HW acceleration but they are trying very hard to improve the situation so maybe with time they will be able to use the HW for now the only way we wan't to watch videos with HW acceleration is only WMP which means recoding or atleast remuxing files.
Cheers
P.S. Could you post exact specs of the .mp4 file? What kind of AVC it was and things like that.
in regards to the WMP hardware acceleration.
is it better on battery life than having coreplayer trying its hard out to render a video. even if its a small 320x vid that plays at 120%. Does that mean that the cpu is running near max?

how to improve video playback

i know the Diamond is positioned as a multi media phone, but every video/movie file i play on it is very jerky. From cartoons (southpark) to music videos and converted movies, they all play like crap. is there a way to improve the performance of video playback?
What player are you using?
I use CorePlayer. It plays perfectly smoothly. (both AVI's and H.264 mp4's)
I've just been using the stock player
Use CorePlayer.
When people ask a question, they put a question mark at the end.
so no free solutions/players to solve this issue, eh? Wasn't planning on spending $20 for a media player.
You can try TCPMP (the seed of CorePlayer). It´s not as much optimized but it´s much better than the Windows Media Player, and plays much more formats.
Search the forum for "TCPMP-0.72RC1-ARM-PPC-recomp-03.CAB". The standard version of TCPMP doesn't run in WM6.1, but this one does and includes the more common plugins (MP4, AC3, etc...).
Good luck.
I got some nasty vsynch issues when playin back AVIs using Coreplayer, both in Directdraw and GDI modes. I convert AVIs to 320x240 using SPB DVD, because native resolution (DVD format for the most) is quite sluggy. In 320x240 it's perfectly smooth, except those v-synch issues. Do you have the same issue ?

I rendered to 320x240 also using tcpmp it plays smoothly, but only uses a small part of the screen. switching to fullscreen or zoom -> framelags about 20! secs. very disgusting. This Phone seems NOT to be a multimediaPhone
I'm using TCMP, think i use GDI mode.
No Vsync issues, no problems. 90% of media files work perfect (avi,divx,etc)

yes but in what quality and bitrate
edit: now thats weird I tried play same movie 640 x 364 avi and benchmark:
coreplayer QTv mode high quality 96%
TCPMP RAW dither on 99% so where is problem with QTv support??? Yeah and there is with GDI and also RAW discusting vsync issue
anyone know if its better xvid or divx in case of performance???
