Hi, as far as i know stream based format are not yet supported in UVC driver. and UVC 1.1 specifications defines the H.264 payload specifications. I dont think they are implemented yet.
I have a camera with me which outputs H.264 stream using MPEG2-TS container format. If you have any idea how to add support for MPEG2-TS please let me know. --Ajay ----- Original Message ----- From: "Alexey Fisher" <[email protected]> To: "Kofi Jedamzik" <[email protected]> Cc: [email protected] Sent: Wednesday, June 15, 2011 8:10:36 PM Subject: Re: [Linux-uvc-devel] Webcam with H264 encoder not in Devicelist Hi, theoretically this should do it: gst-inspect-0.10 v4l2src ! video/x-h264 ! ffdec_h264 ! autovideosink but, if i'm correct, current kernel do not support h264. There was a patch for some time, but im not sure if Laurent applyed it.
