[linux-uvc-devel] uvc h264 in guvcview testing required

Hi,
I've just added uvc1.1 h264 stream support to guvcview, the last git
version can be checkout with:
git clone git://git.code.sf.net/p/guvcview/git-master guvcview-git-master


You will need the h264 codec from libavcodec for decoding, I think
this is in the extra package:
libavcodec-extra

If you want to mux the stream into avi or matroska, make sure you
choose the h264 codec from the video codec list, this also requires
the encoder codec, although if no video filters are applied guvcview
will mux the raw stream, no software encoding, ( very cool ;)
***@30fps on a usb2 plug even on a 7 year cpu).

I must thank logitech for sending some cameras for testing, without
them it would have been mission impossible.

I stiil need to clean up the code a bit, add a codec check for
disabling h264 support if the codec is missing and add the stream
controls, but I would like anyone with h264 uvc cameras to test the
current code and report any errors/bugs or whatever issues that may
come up.

I also have a c930 (uvc 1.5) that I would like to add support, but the
current uvc driver version needs patching (
http://www.mail-archive.com/linux-***@vger.kernel.org/msg66203.html
) to natively support uvc1.5 h264 streams, so I rather concentrate on
uvc1.1 for now.

Thank you,
Paulo
