Hi,
I developed and app for win.mob.6 for video capture live streaming using direct show filter. WMV9 encoder has very low performance of framerate no more 4 fps with lower res.
I am testing the app on HTC touch dual. I tried to enum all filters availables, but I found only WMV9 Encoder. The original app cam coder can create 3gp file with h263+amr-nb. I'd like to know how is possibile this !!! no h263 filter encoder are available.
I am looking for an htc WM5/6 model that can capture video frames encoded to 15 fps with a mid res 170x140.
help please.
thanks
Hi fala70,
I am sorry but I couldnt quite understand what it is your current status.
Have you developed the application and it is working or you would like to do it now?
What do you mean 'original' application. Are you based on an open source example or something?
Nice subject though!
This issue has been discussed quite a number of times (I asked the same thing a few months ago) but no resolution as come out so far. I think HTC does not allow its "private" encoders to be "enumerated".
My status it that I want understand if is possible to use an other codec encoder different from WMV9. WmV9 is too slow.

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,
Marti
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

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!
Hi!
I hope you guys can help me with a little question: Is the Galaxy time limited (e.g. 60mins max) or size limit (e.g. 4GB max) while video recording? I hope that the only limiting factor is the size of the used SD-Card...
Is it possible to record while holding the device in landscape or in portrait orientation with same resolution without having a video standing on the head at the end?
Which container and codec does the recording use and how many space is needed for a specific recording time (e.g. 1GB for 100mins)?
Thanks for now!

Much appreciated if anyone can tell me what I need to do to be able to change the bitrate setting in media_profiles.xml under /system/etc. I have root but it won't let me save the new value into the file.
I would like to be able to record at lower bitrate since the file size in 1080p and 720p are so huge. Looks like the max bit rate is up to 20mbit/s. default for 1080p is 17mb and 720p is 12. I want to lower to 4mb for 1080p and 2 mb for 720p and see what the quality is like.
If anyone knows of a better way plz let me know. thanks.

Changed the settings on my media_profiles.xml but it still doesn't record at different bitrate. Much appreciated if anyone can help or have been able to change their recording bitrate. Is there something else different regarding the samsung s4 cam settting?
Anyone? much appreciated. thanks
hi to all,
I would like to add new media profile under CameraID = 0
right now I have the default profiles (1080p/720p/480p....)
and I want to add a hi-resolution low bit-rate profile without loosing any of the mentioned above, so in the camera app I will have something like this:
in the video quality settings - 1080p, 720p, 480p, 1080p-lowbitrate (for example)
my question is how can I add such a profile?
when I tried to just copy one and change the bit rate (and profile name ofc) I had bootloops
thanks in advance for helpers
