Video playback problem (not that it's slow). Garbled screen.

So it seems that I'm unable to play back any video format besides WMV.
WMV's play back fine while other formats (e.g. xvid, divx) do not play back at all. Coreplayer crashes to today screen or shows me a green garbled screen with vertical lines.
WMP just freezes and does nothing.
Is this a known issue (I didn't find anything using search)?
Any format of audio plays back perfectly fine (as long as it is not embedded in a video).

I had this, you need to change the Video driver to Raw frame buffer and all will be well. I use TCPMP and this was what I had to do for it to work.

I had done this at first initially too, but simdeo (fellow member) suggested Imageon setting, but NOT Imageon Hardware decoder. This has massively improved speed and visual quality, but you will get intermittent lines across the interface, but not in full screen mode. Settings should be:
TCPMP:
Video Driver = ATI IMAGEON
Buffering = Microdrive (ticked)
Advanced = Tick only: D-Pad, Use System Vol, Benchmark (none od these settings affect performance, just my preference - but selecting other options may adversly affect performance)
Direct Draw = YV12 and tick 'Overlay with colorkey' only.
That's it. Best performance to date and can play torrent or own DVD rips perfectly, providing they were not encoded as high as 640x480.

I'm having the same problems but cannot for the life of me find any settings on Coreplayer that will let me change the buffer settings or the driver.
I'm sure I'm missing something here.
Coreplayer version =1.0.4 build 716
It's the latest version afaik.

Ok, I found the settings in Coreplayer (yeah, I know, should have looked harder..) and all is now well.

Ok, so I've got really decent playback from standard 350mb XVid TV programs but I'm still having what appear to be buffering problems.
Does anyone know what the ideal buffer settings are?
Adey

I have found that overclocking the CPU yields in much better playback (although not perfect).
If I want to view a 640x480 video I run the CPU at 728 Mhz (what program would allow higher?), but still the fps is not up to par. I would say the playback is around 90-95%.

Hi Calavaro. What app are you using to o/c the CPU? & exactly what settings do you use? Oh and lastly what's the power consumtion like if left on 728 Mhz all the time?
Cheers.

we use PHM to overclock our device, if you set to 728 and push mail and bluetooth all the time, you won't last for whole day, maybe just about 7 hours. But really you don't need your device on 728 all the time, and personally i think 728 is a bit unstable, so i use 662 when my device is on, otherwise 228 the rest of the time to save battery.
You MUST disable the internal scale from the PHM setting, otherwise it won't work

just wanted to say thanks for this thread. was going nuts with the same problem re: vertical lines, pink screen, etc. almost made a post to ask you guys what kind of parameters or settings you used for your video players. i use core and i confirm that the "raw frame buffer" works well.
cheers

About TCPMP with the best settings applied as mentioned in this thread, is there something else we can do to further improve the playback quality?
I have some clips that feature "fast moving action" e.g. action scenes in movies. These clips will actually play, but when the "fast moving action" is there, you can see that it isn't going really that smooth/fast enough, resulting in noticeable, fast upcoming blocks/lines when you look closely. I'm not sure how to describe this effect best, but I guess pretty much everyone knows what I mean here.
Thanks!!

Hi.
Try playing any 3 minute segment of the video you have then click on File/Media Info and check the resolution of your video. If its below 640x480, then the problem is most likely a low bit rate used to encode the video, hence the pixelated blocks in high speed.
You can get away with less, but I encode now only at 480x320 @850kbps and get superb results each time...DVD quality and High definition quality too when I encode from HD source.
Can't say anymore than that. Click on my name and look through my posts, there will be a recent one entitled something like 'Excellent playback via Coreplayer & TCPMP'. This should help a bit if you have the time to read.

Large & CIF Camera Video resolutions hack

HKLM\Software\HTC\Camera\P2\MainCamSupportCapSize = dword:0x0A (10)
change to dword:0x3A (58) and you will have Large & CIF resolutions.
Dmitry

can u explain better how to do it because when i go in i cant change the dword value and its # is 10 for me

Use any registry editor (like Resco Registry Editor or PHM Registry editor) and going to the HKLM\Software\HTC\Camera\P2\MainCamSupportCapSize . Default value is 10 decimal (0xA hex). Change value to 58 decimal (0x3A hex).

I modified the registry for these values and it does seem to increase the quality but not the image size of the pictures or video.

After registry patch the L & CIF resolutions will be available in video camera mode. Try to click on resolution icon on top bar or select it in options.

the new resolutions are
L = 320x240
CIF = 352x288
which are much better than
S = 128x96
M = 176x144
thanks for the info

i made the edit and it enabled the two resolutions in the options, but when i actually tried to take a video with those settings (either large or CIF) it came out as the same low resolution it normally does, but the video quality is even worse (very choppy). is there a way to get around this?

No problem. HKLM\Software\HTC\Camera\Recparam\MP4Large\Bitrate
default value 128000. I chaged it to 1024000 and now video quality is better.

hey, thanks for the reply...did what you said, and picture quality is better, but video is still very choppy and still much below the framerate id get while recording in medium. id be happy if I can just get it up to 15 frames per sec at this quality.

MJPEG @ 15FPS seems to be the sweet spot with Dmitri's tweak
Thanks for this tweak Dmitry! After spending few hours testing various settings, I found that using MJPEG @ 15 FPS got me the best results in both visual quality and framerate consistency (FPS for MJPEG can be set under Recparam\AVILarge although 15FPS is the default, if I recall right). Anything higher than 15-20 FPS with high motion videos will result in erratic captures.
Note also that you'll want a fat MicroSD card to store MJPEG videos as these can become large fairly quickly.

This is an amazing reg tweak, i knew it was a matter of time before this leaked out. This camera is more powerful than whats let on and i know it
Now if only we can get some frame rate tweaks in here that work

Well I actually got the frame rate to not be so choppy by just changing HKLM\Software\HTC\Camera\Recparam\MP4Large\FrameRate to 5 Hell you may even be able to go lower. Because that's all I kept doin an it just seemed to get better each time I lowered it.

Changing the framerate to 5FPS for Mpeg4 yields horrible playback results. It's not even worth taking videos with the setting at 5 because of the slow, jerky movements.

5 frames per second? That is REALLY choppy, maybe you meant 15?

i've done some testing and it seems like mpg4 just uses too much processing power to do the compression and that motion jpeg (AVI) at 15fps yields pretty good results. will try and do some more testing and report back.

my only problem with using motion jpg is that audio stream format doesnt work with tcpmp, so all my beautiful movie automaticly become silent films out side pocket media player

I messup. I changed the maincamsupportcaptsize and dont remeber the org setting. the 2nd problem is that i could not add change to dword:0x3A (58) it would only let me change from 8 to 58 but not the 0X3a?

Not sure if changing this messed up my MMS but I haven't changed any other feature. Right now after doing this hack, my MMS won't send out, giving me an error that says my image size of 16k or whatever is over the 0k limit?

Reseting to default
thanks for the info but I have tried that reg hack and it will stay at 58 until i launch the camera/camcorder function then i go back in and it is back at 10. don't know if i need to soft reset before i launch cam? any help would be a appreciated.

"Perfect" HandBrake settings for TP2?

So is there such a thing as "perfect" handbrake settings for TP2?
I've been playing with it a couple of hours, and these are the settings I'm down to using:
Output Settings, Format: MP4 file
Picture Settings tab: 640 x 400 (what are you guys using?)
Video Tab: Video Codec MPEG-4 (FFmpeg), framerate 29.97, 2 pass encoding, average bitrate (kbps) 600
Audio&Subtitles tab: Automatic Source, AAC Audio Codec, Mixdown Dolby Pro Logic II, samplerate Khz Auto, Bitrate (kps) 160
I haven't really touched anything else, but with these settings I seem to be getting the slightest lag where sometimes I can perceive the frame rate, for lack of a better term. It's as if the smoothness is about 90% - 95% there, but not quite. Anything I can do about that? I tried making the width x height numbers smaller, but it didn't seem to work.
What are you guys using for handbrake settings? Are you touching any other settings than the ones I mention above?

I've tried all sorts of setting with HandBrake (including yours, just now) and there always appears to be a bit of a stutter. I've had much more luck using SUPER encoder (encoding to AVI).

I just reencoded a divx file to MP4 using x.264 compression and it plays smooth as silk using the HTC album application. That was on the latest 6.5.1 (504) Valkyrie (sp?) ROM as of a couple of days ago. I am probably going to flash to the new 28002 Energy ROM tonight so we'll see if it still works there.

What were you other settings on handbrake? I guess you selected h.264(x264) under the video tab. What did you use for avg. bitrate on the video tab and what did you use for width/height or anything else under the "picture settings" tab?
I'm not familiar with the ROM stuff you're referring to.
Thanks for the info. I'm still playing with these handbrake settings!

Sorry, the site freaked out and I couldn't finish my post. Anyways, I actually used the free version of Any Video Converter and not handbrake (I got them both about the same time. That theoretically shouldn't make that much of a difference though when using the same settings. It just seems a bit easier to me to use.
I went with the original size. It might not make a difference but I have this nice, high-res screen, might as well take advantage of it, right? Original size in this case was 592x320. Video bitrate was set at 768k and the audio was 128k AAC. Windows shows them slightly lower in the file properties for whatever reason, though, 749k and 125k respectively.
My final file size was around 554 MB compared to right around 1000 MB for the original xvid. This was for an hour and a half movie.
I think you could approximate the settings by using the xbox 360 profile and changing the target bitrate for video and audio to something closer to the values I used.
Edit: This is the link to the ROM I was using. You will note that it appears to have updated D3D drivers so that might make a difference as I have heard of people having stuttering issues with WM 6.5 using the HTC album player in Manila. I point that out because the HTC player is apparently one of the only ones capable of taking advantage of the GPU accleration in the phone to handle the video decoding. Other players are more likely to stutter due to doing CPU decoding.

Presets
I haven't used Handbrake in about a month. I used 0.93 for Windows. When I converted something for my phones, I would use the Iphone/Ipod Touch preset. It's converts to a h.264 MP4 file. I would dial back the resolution for my Tilt. With my Tilt2 I raise the preset resolution to 800 instead of 640. I play it with the latest Coreplayer or TCPMP GF5500 Edition. The videos are amazing. I have been trying the GUI posted earlier because it's much faster.

Ok thanks. I'll have to try the x264 setting. I thought I tried that once with handbrake when I was playing with a 10 minute DVD trailer, but for some reason my TP2 wouldn't play it. It might have been just a bad file conversion that particular time, but I assumed at the time it was just an unusable conversion type. I have been using the MPEG4 (FFmpeg) file and that seemed to work every time. I haven't a clue what the difference is.
I think I'm still using WM 6.1. I'm relatively new to this stuff and I'm not too sure about what a ROM is. I know it means "read only memory," but how it applies to my phone or how I can modify it and what the consequences are of changing it- I don't understand.

Ive used Super to convert a DVD rip of Iron Man to my TP2 @ 720x 480 resolution @ 1200kbps in MP4 h246 and it looks sexy! you have to make sure all other apps are closed and surprisingly enough, Windows Media Player handles this file with ease(Windows media player actually works now!It only took 10 years!lol) and framerate is movie speed @29.970. Even more surprising is the fact that this is playing on a virgin device( running the stock ATT ROM till tomorrow....) and the current ROM is incredibly bloated.

"Avidemux" is an awesome program to easily convert your movies. I use "Handbrake" to RIP but I find "Avidemux" much better for movie/video conversions. it has presets but will also let you setup formats, crops, etc. anyway you want. It has enormous capability and still easy to use. I use it to convert to 640 x (?) (xvid) mp4 @ 700 kbps with 128 kbps AAC audio for use with the Album player and it is sharp with no stuttering. I am going to use it to convert to x264 mp4 @ 1000 kbps and see how WMP handles it as a test but I generally despise WMP.

Handbrake
I've never posted here before but after trying Core Player and its stuttering after I installed Mighty Rom i found that using the standard IPod Touch and Iphone settings showed video clear as all hell with no stutter (changed resolution - increased a little).
Try it?

The Best Settings and the best CONVERTER For TP2
In 2 weeks I've tried it all. 8 converters to be exact. The best one out there worth anyones time is a converter call AVS Video Converter 6.3(not free but reall worth it trust me). It has it all! It's pretty quick compare to the rest, but most importantly pumps out excellent video quality with smooth framerate. There's a few that's faster but most of them has bad famerates, bad quality, or both. Yes bad framerate playing on my super computer. The best settings that work for my TP2 is the following:M4vipod at 415 bitrate, 24fps, 640X384. Plays smooth looks great can't ask for more!
Converters I Tried: Handbrake 9.3 too slow
Handbrake 9.4 got sound no video?
Iwisoft choppy framerate looks very promising waiting for a newer version
Ultra mobile 3gp not enough settings file comes out to big and to slow
Any Video Converter when it works it very good, freezes to often during conversions plus to slow.
And a few others I don't remember.
Thanks hope I can help.

how come I only got the sound with no video from the H264 files I converted with Handbrake on max OS X....

I have been trying to get my new Sprint Touch Pro 2 to run movies smoothly using Windows Media Player Mobile. This is a very difficult task... I think I have just succeeded. At first, I was using Handbrake to encode my DVD using the 640 resolution setting. This worked great for playing on my home computer, but after using Mobile Device Center to Sync my TP2 and playing the MP4 in Windows Media Player Mobile, I only got video to play and NO AUDIO.
This was very frustrating for a long time. I finally solved the problem. I increased the video resolution to 720 in Handbrake (leaving the audio settings as is), and bingo....the audio and video both play using Windows Media Player Mobile. I used the 23fps, 16:9 setting and 768 bitrate and it plays pretty well. Not sure why audio is not playing using the 640 resolution...any ideas???

So I must be doing something wrong. Im using a failry new pc (Acer Iconia Tablet PC) and I started to convert a file in Handbrake last night around 12, 8am this morning its still converting.. what is the deal here?
I am trying to convert a .m4v file to .mp4 and the issue is that the file has subtitled I need to have burned in. I typically use videora but it didn't recognize the file.
I did the settings here (iphone settings) and i actually queued up 2 versions one with ac3 audio and one with aac, not sure which one i was supposed to choose.
Everything else was standard (subtitles burned in).
the movie is a 2.5 hour movie why is it taking so long.
I wish I was better with using vlc's conversion settings.

Double post on accident

I don't know the perfect settings, but these at least get you going with good results. They require modifying a profile which is x264 level 2.1 before I found this out I had some hit and miss results with 0.9.3 occasional green screen with sound in the Album player and consistently no video in the higher versions.
I'm using 0.9.5 now. The first thing you want to do is uncheck "always use iPod friendly file extension (.m4v) for mp4" in Tools>Options>General and maybe enable Query Editor tab in Tools>Options>Advanced/Other.
Then you want to pick the level 2.1 Apple preset: iPhone & iPod Touch
Change the Audio Mixdown to Stereo, Samplerate to 48
Change the Video to Avg Bitrate 1000 for lower res, 650 for near or full 800x480
Preset>Save Preset
Minor changes to the new preset can now be saved by right clicking on it.

Encoders need raw power your tablet PC has a specialised processor. I don't think you can burn in subtitles yet in Handbrake unless the source is DVD and they're VobSub (unsure about BluRay source) and the Audio must be set to AAC.
I think you will need to use Avidemux which has support for burning in many subtitle formats. I didn't have much luck with it up to now as it appears the Windows stable version r7200 is quite broken, partially rendered VobSubs, and crashing during encoding. So far so good using the latest beta r7317 hosted by Gruntster on the iPod preset.

Video recording not working in 640x480

Guys, my video recording does not work in 640x480 nor in 320x240. Sound is recorded, but no video... Only CIF works like expected (Video with sound).
Anyone else with that prob?
Thanks,
Marti

Hi,
i got the same problem.. there are only sound on the video recording..

The same after installing "ringtone-patch".

got the same problem. only works in CIF resolution with H.264

I do not have any problem recording video both on momory and SD card and with sound in 640x480 / MP4.
Could you explain how to reproduce this behaviour ?

I fixed it by deleting HKLM\Software\HTC\Camera\recparam\MP4VGA registry key.
If you afraid of deleting, try to rename it.

YESSSSSS!!!
It works fine after deleting of this reg key.
Best regards to all,
Marti

is it really working?
when I bought HD Mini the recording in VGA quality worked fine. I did some customizing (nothing unusual- just installed some apps and tweaked manila to my liking) and.... the VGA mode stopped working. It records audio only. I tried to delete the MP4VGA registry key and after this HD Mini records video in VGA but:
1) the video quality is very poor when compared to the recordings before problems. I checked the files- the resolution is the same (640x480) but the bitrate is drastically lower- it is 375 and used to be 1441. it looks awful
2) the funny thing is that when I opened the registry editor the deleted key is back again. I am a newbie to registry editing and have no idea if I deleted it the "wrong" way and how it restores itsef. I tried several times and after soft reset the key is back again
My most important question is: mrmartischmi and darknos- can you record a high quality files ( hi bitrate?) after the tweak?
thank you

@robertszydlo:
Sorry for the late answer.
You are right:videos have a very low bitrate and thus are of bad quality.
Its false to delete the folder MP4VGA.
I restored it from my backup and set the key "Bitrate" to 1500000.
This made my Videos look much better and the Bitrate returned to be about 151 kBps instead of only 40. Higher values did not work though.
Hope this helps, I am investigating more at the moment...
(maybe someone can post the complete "original" keys of the MP4VGA folder?)
Thanks so far,

yeah! this one really works (Thanks mrmartischmi!) but it gets me even more confused
after setting the value to 1500000 my phone records great looking videos but the files and the bitrate(well over 3000 now ) are huge! I don't have a problem with large files - it just makes me think:
-what was the original value ( can someone please check and post?)
-why in the world it stopped working? can I expect now to work continuosly and not fail while recording my masterpiece video ?
thank you

@robertszydlo:
I only got 151 kBps, how can yours be 3000?
Did you check on the PC with Quicktime or something else?
Could you post the size, duration and bitrate of a sample video so I can check with the parameters of one of mine?
I am pretty confident, we will understand it in the near future

(maybe someone can post the complete "original" keys of the MP4VGA folder?)
Thanks so far,

I'm using 1.32.479.2 WWE ROM with the last HTC hotfix installed. Bellow is MP4VGA key folder, exported from my registry and a screen with info about a short video i've just made.
I've checked the "bitrate" key and mine is 1500000 too.
Hope it helps.
EDIT: the keys have the original values and i don't have any problem with video recording.

mrmartischmi,
I am not any math expert so I can make mistakes- that's why I don't try to convert bits to bytes or do any math I just give you the numbers I see on my mac screen when I "get info" about the new file (value in registry set 1500000) it says it is 640x480, codecs MPEG-4 Video, AAC duration 00:16 audio channels 1 , Total bit rate 3,217. It is probably the bitrate of audio+video in bits? I am not sure how it compares to your 151kBps but your bitrate can be video only expressed in KB.... there are probably many guys on this forum that can enlighten us
ci6i,
thanks for help, the one thing that is strange to me is that before any tweaks my phone recorded files with much smaller total bitrate ( get info says 1486) so maybe in my rom the original registry value was lower?
anyway, yesterday I recorded really long files and everything works, so I am happy

@robertszydlo:
Sorry, it was not my intention to bother you with maths... I was just wondering, why the rates are so different although using the same keys in registry. Could you post the filesize of the small clip you mentioned before so I can compare these parameters to a clip of mine?
@ci6i:
Thanks a lot for your help. I compared the values of the reg key to the ones I have now and they are ecactly the same.
So the question is: why did robertszydlo recorded videos with a much smaller bitrate before the tweaking? Maybe there are other keys to change ...

I'v discovered days ago that this bug is generated by using BsB Tweaks with option "Video MPEG4 Bitrate" enabled or HD2 Tweak with corresponding option enabled..........don't use this tweaks utils if not certified with HD MINI....

hi mrmartischmi,
I uploaded 2 videos- nr 1 is recorded the first day I got the phone, no tweaks
nr 2 i after the last tweaks (value 1500000 in registry) ... bigger bitrate ant bigger file. Can I see difference in quality? well- I am not sure- see for yourself
@ SoftWord: you are probably right! I switched the bsb bitrate tweak on, and this could cause the whole problem, thanks for your input

The best quality I got when remove all keys from MP4VGA registry folder except one: BitRate = 1500000. but 15 seconds video is almost 6Mb on card
Notice: If you leave FrameRate = 20 or 30 in MP4VGA, video file size will be about twice less and quality will be worse.

def that's the problem why the video recording not working. without it my video recording's working fine.
watch out with this setting, guys!

Media_profile.xml modifications

I was looking at the media_profile.xml file from the Xoom forums (posted and edited by bracken21, Thanks for the work) and noticed that the file was different than the Asus TF one. Instead of trying that file on my TF I modified the TF profile.
I have experienced no problems so far with this modified file but try at your own risk, replacing the file with the original should resolve any issues you might experiences, but no promises. I highly recommend backing up your own media_profile.xml instead of using my backed up original.
A few questions for anyone that knows.
For the camera app what is 'high' quality? I assume it is the 720p profile do to the outcome I had. I ask because in the media profile there is no youtube video quality but is on the app. other video quality names aren't listed in the app either.
What do the video decoder and audio decoder caps do exactly? I turned them off only because they where turned off on the Xoom, and I wanted to see if it prevented video from playing or caused glitch's (I saw no issues in the video I played)
I set the camera to the rear and "high" for quality then recorded a video before the changes and one after then transferred them to my desktop. The details in properties shows both at 37 seconds long and a frame rate of 1280x720. the data rate for the 3gp was 7478kbps while the mp4 was 20350kbps. Total bitrate increased from 7574kbps to 20446kbps. Frame rate dropped from 28fps to 24fps. file size increased to 93MB from 33.7MB. I noticed a small improvement in quality at full screen on my monitor, it was a slow video so I couldn't tell if it had more or less tearing.
more info: You will need to reboot to see any chances. setting any setting the camera can't use will result in the camera app force closing. I tried setting the frame rate to 40 in one profile and the camera app crashed every time I tried to access the rear camera (that profile was already selected so was auto loading). placing the xml with the correct framerate back into the /system/etc folder and rebooting fixed the issue.
Since it is a busy day today for me I just did some quick modifications. If anyone else wants to make a modified file with better changes (specially someone who knows audio/video better) it would probably be appreciated by all.
Placing this file where it needs to go requires root and a file browser that can mount the system folder in read/write.
The XML file should be placed in /system/etc. the full path is /system/etc/media_profiles.xml
changed:
All 3gp encoding to mp4 encoding
Rear Camera 720p quality bitrate from 8,000,000 to 25,000,000
Front Camera high quality bitrate from 4,000,000 to 8,000,000
Changed both "imageencoding quality from 90/80/70/20,000,000 to 100/99/95/250,000,000
Turned off videodecodercap and audiodecodercap
Again thank you to bracken21 for doing the Xoom's profile, which provided a base to go off of.
