Hi Srinivas,
Patches are attached here... There are more modifications I did to uvc_video to
set size of buffer + fid bit toggle after 44 MPEG2-TS packets. What kind of
camera are you using?

Thanks Ajay! I just got a B990, and am trying to stream out H264.

Hi Srinivas,
UVC fixes wont be needed for you to get your cam output..
You can build gstreamer0.10-ffmpeg to decode H.264 stream, Robert has used
fluendo package for decoding.

Hi,
I would like to add support for H.264 stream format in guvcview, Could you
post some stream info, or even better an example of raw data output (does
the capture buffer contains an exact frame like in MJPEG ?)

Paulo

Hi Srinivas,
Hi Paulo,
I am not having H.264 camera, My camera is similar to Facevision's Touchcam E1.
It sends out MPEG2-TS stream encoded with H.264. I have recorded some videos
during my testing if that is fine for you I can send across... it would be
great if guvcview can show compressed streams :) we
Hi,
I was thinking on using ffmpeg (libavcodec) since this is already a guvcview
dependency for enconding the streams, decoding them shouldn't be to hard, I
just need to understand how they are handled by the driver.
This is the reason I need the raw data, you should be able to use the v4l2
Hi,
have you tried the open svc decoder (
http://sourceforge.net/projects/opensvcdecoder/ ) ?
It would probably be easier to add as dependency.

Hi Paulo,
i have video dump from Robert, not v4l2... The problem with it is
Hi Paulo,
for me ffdec_h264 worked perfectly... I used current stable release of
gstreamer-ffmpeg. It has many more formats...

Hi Robert,
As you know its a development camera... I think my camera need some fixing.. my
hardware decoder does not work with H.264 stream directly... I added h264parse
element before h264 decoder in gstreamer pipeline to make it work.

Well one important thing to notice is the pixel format returned by the
driver, will it differentiate between avc and svc streams, or even
mpeg2 ?
If not maybe then it becomes harder for generic apps to decode it,
unless we use a bunch of switch cases for the different cameras
(something like this
Hi,
see attached a patched capture example, for saving the driver output
buffer into raw files (200).
I haven't been able to test build it, but the changes are minimal so
it should work.
You just need to change the resolution, and maybe the pixel format to
whatever the driver expects.
see lines
Just remember to set the -o option when grabbing the frames (the
output will be redirected to the files and not stdout as displayed in
the help message)
These files should allow me to add support for the camera in guvcview.

Paulo
