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?

Perhaps you could tell us what you are attempting to play these with.

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 ?
Thanks again,

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.

This MP4 doesnt play on my pc only the phone???

I have an TiLt and when i try to record videos on my phone in MP4, it appears to work fine and i can play it back on my phone using TCPMP. but when i try to run this on my computer rnning vista it only shows video with no sound.
What can be causing this, is there a way to fix this and has anyone else noticed this..
ps. i hope ths has not been spoken about b4, i hate sounding like a nubie

There's lots avout video formats in the wiki here:
http://wiki.xda-developers.com/index.php?pagename=The H.264 (a.k.a. MPEG-4 Part 10 and AVC) Bible
FWIW my mp4s recorded on my TyTN II wont playback on my PC either, it's simply a case of finding a suitable codec.

recorded videos on Tilt not playing on vista with sound!! I GOT IT FIXXX

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.

Playing video on Tilt (Choppy picture)

I just installed CorePlayer and when I play video (WMV) It's extremely choppy. I also tried it on WMP and its also very choppy. Any suggestions on how to remedy this? TIA

check your specs on the video,codec,bitrate, etc

Check out Coreplayer, it really improved the view and choppiness on my movies.

LOL, he already said he tried coreplayer

set the video settings to raw frame buffer and see if it helps

Call HTC and ask them to send you the video drivers for your phone.

Are there any specific or recommended settings for converting to AVI of WMV? Divx or Xvid? What setting for those of you that have gotten video to play what settings do you use? I'm using TMPGEnc to process the video.
The phone is not even 3 months old. Doesn't it come with the latest HTC drivers? Can I download them?

The "drivers" is a joke. They Kaiser is missing the Hardware Graphics acceleration drivers. Check out http://htcclassaction.org.

My problem is that video playback seems random.
I've converted some video clips I've downloaded from the internet, using PocketDivXEncoder, and am using CorePlayer for playback.
The first time I view, the quality is great - but subsequently they are choppy to the point where they are unwatchable.
I can't understand why this should happen.
I've played around with a few things - I thought I'd got it sussed when I moved the clips to the DCIM folder, but again it only worked the first time.
Weird...
As a side issue, for future reference, what are the recommended settings for quality/size/bitrate etc. when trying to load video onto my TyTN II?

It seems to me that you have some program running that sometimes uses a lot of CPU resources and prevents the video player from using them.
As for encoding, I'm usually using ~350kbps divx video/128kbps mp3 audio in 320x240 frame size.

I thought that...
Closed all apps, even did a soft reset...
(Thanks for the numbers by the way)

Coreplayer for Xperia jerky and skips.

Guys i recently installed coreplayer for xperia. The issue i faced is the video playback is not upto the mark. Its kinda jerky and stops skips videos in between and not smooth.
Has anyone faced this issue with X1 by the way my friend has omnia and the same verison of coreplayer installed on his cell but the video playback is perfect without any skips.

same here...bought x1 5 days ago tried everything and that piece of crap doesnt work same as coreplayer :/ i downloaded the Video...Encoding...GUI_Full.HD stuff which converts video...converted one but the movie on X1 doesnt look like a movie !! it looks like a slideshow but guess what windows media player plays this video Perfectly...written by the big P so im asking wtf ??

the X1 does have some performance issues. this has been discussed several times in the past
the omnia performs a lot better because it has a much faster CPU and because the resolution is 1/4th of that of the xperia so it does not need to work as hard to get smooth playback

core player doesnt support x1 hardware acceleration... thats the main problem there

ok ok but what to do ? im playing aroung with it from the day i bought it and nothing that i tried helped and im a bit frustrated :/ i dont wanna use wmp

Maybe you should get an IPhooon its click and play no hussle and stuff no need to tweak and every thing works (well every thing that comes with it)

install custom rom... gfx booster... convert videos with tool posted here on forums and play them in media panel... no lag at all...

Media panel and converted movies is best solution. And no, you don't need custom rom.
Crystal player is just useless. Yeah, it's sad.

well thats wierd, i play 700mb highres avi files on coreplayer without any problem, maybe its the videos you try to play..? i only face lagging with flv files.
btw i have stock uk r3aa010

I found that some people find 80% speed 'perfect'. I can spot single dropped frame.
Run benchmark a post the results, subjective value is meaningless.
And yes, of course, it does depend on the movie. I play most of the 700mb movies under 90%.

i have not had any problems with coreplayer either....

The movie i am playing is in mkv format and around 500megs in size

1-Use HTC Touch HD video converter
2-Play your converted video with windows player or the media panel
3-Have fun

I have CorePlayer 1.3.2 and i played recently a movie DVD-Rip of 1.45 Gb straight copy and paste from my computer on Xperia. Had no problems, i watched the whole movi without lags, frameskips or sound not synchronized with video...

That I simply cannot believe. Post benchmark results, and movie info (resolution, bitrate).

Me neither. 80% is what I usually get as speed with 1.3.2. Btw this DVD-Rip may be some small resolution, like 640x272.
I just don't get it, such a good phone with such a lousy movie playing capabilities.

OK... here's the facts.
It's all about perception. Some individuals can watch a movie that displays at 24fps (frames per second, which is the standard) and see a perfectly smooth movie. The brains fills in the gaps between each image and creates the illusion of full motion.
Some lucky individuals can look at a movie playing at 20fps and still see a smooth movie while most of us will perceive it as jerky.
Some unlucky individuals (myself included) find anything less than 30 fps to be jerky.
And finally. Coreplayer + xvid files do not use the acceleration feature of the chipset hence the standard *cough* downloaded tv show will usually be and 624 x 352 with a 912Kbps bit rate (These are average stats)
Will run at about 80%-85% framerate on your X1 giving you a fps of about 20fps.
If you reenconde using the sticky programme GUI you can play the same file at 100% USING ONLY WINDOWS MEDIA PLAYER/MEDIAL PANEL!!! (coreplayer will still run it at 85% ish)

Yes .. I just want those people who can watch movies at 80% to realize how lucky they are

Well, there has been so many threads on this subject...
I don't see where the problem is to use Windows Media Player to watch a movie, it's just perfect. Files that cannot be opened by WMP (like flv for example) can be opened with CorePlayer, that's nice.
I don't want to hurt anybody, but maybe people whose mind totally deny this very simple concept should may be go to see a psy We have the right tools, they work perfectly, so why do you want to re-invent the wheel ?

Well most people want to watch AVI movies .. and those are not watchable in WMP and jerky in CorePlayer. If you don't want to watch them, good for you.

what do i have to do to get smooth video?

This is a great place!
I have been reading all the threads that might have anything to do with video playback.
I've installed those 3D drivers and graphics were improved on that hologram thing and "light 3d"
Still, video playback is choppy and im grinding my teeth seeing it!
I have converted videos in all kinds of formats in all kids of FPS and KBPS and kept VGA resolution and still no use.
Have i missed something?
thanks!!

what media player are you using dude? ive been using TCMP for the longest time and i have no problems on playing my videos/movies...

i tried using the built in windows media player, coreplayer, and i have used tcpmp once but the bottom taskbar was black so i didnt know what problem that program had.
anyways, the tcpmp didnt play smooth. maybe i had a bad version?

Have you tried viewing some other content other than your own converted files? try using the attached sample avi with all 3 players and see how that goes.

ive tried the videos that came with the phone.
windows media player handles videos much better than coreplayer but still no smooth video.
this is weird, on other ppc's that ive had (a few) coreplayer/tcpmp played videos much better than wmp.
over here its the exact opposite.
how come?

what ROM are you using?

original ROM that came with the diamond.
in my case its 2.o3
israel orange

help? anyone?

I don't know anyone here who is on the same ROM. you could try upgrading the ROM??

what ROM should i use?
can i extract the hebrew that comes with the ROM currently on my diamond?
i kinda need it

well of course that the built in WMP will play the video smoother than the core player. It`s because only WMP can use the hardware accelerator in the phone.
still the core player don`t have the proper drivers to access to the GPU.

ya it plays smoother, but still not smooth.
and theres all this tearing.

make sure you use qtv

With TCPMP set Video to GDI.

i installed tcpmp and when i ran it it came up with a message "crashed"
and it won't run.
i used Qtv with the coreplayer and it was still slugish

Be sure you use the version on this thread:
http://forum.xda-developers.com/showthread.php?t=519543&highlight=TCPMP
It works great on my Diamond.

Ive installed a tcpmp from another thread from this forum.
It works and plays videos but its still slugish.
Is there a patch or a fix i was supposed to install?

Smooth video playback
Hi all,
I was having problems with jerky video playback.
I did some searching and found this link-
http://forum.xda-developers.com/showthread.php?t=467112
It works a treat really smooth and in 640 480
WELL DONE

I saw this too...
It doesn't play smooth on my device.
still, this is the program i use to convert video if i wanna play something on my diamond
even tho it stinks (the diamond not the program!)

Hi idandavid,
PM me your email and I will send you a mov video of my Diamond playing a smooth video.
Or send me a video, I will conver it and try playing it on my Diamond. I can then send you the converted file to compare on your Diamond.
Hope this helps
