[14:26] <Ford_Prefect> Hello
[14:26] <Ford_Prefect> Looking at the buffer flags set by the v4l2 driver on a Logitech C920, I don't see the keyframe flag set where appopriate
[14:26] <Ford_Prefect> And I didn't see any code that should be doing this in the kernel either
[14:27] <Ford_Prefect> Is this missing functionality, or ...?
[14:35] <prabhakarlad> Ford_Prefect: If I am not wrong the there isnt any driver logitech c920 camera, It probably uses UVC
[14:36] <Ford_Prefect> prabhakarlad: correct, I was looking at the uvc-related code
[14:36] <stormer> pinchartl: ^
[14:39] <prabhakarlad> Ford_Prefect: Yea there isnt any functionality in UVC as of now. But I feel it should be easy to add. Altough Laurent would be better person to answer this

[14:41] <Ford_Prefect> Cool, would be nice to have
[14:48] <pinchartl> Ford_Prefect: I suppose you're referring to H.264 support ?
[14:48] <pinchartl> UVC 1.5 isn't supported in the mainline kernel at the moment
[14:50] <Ford_Prefect> pinchartl: yes, the h.264 support. So uvc 1.5 is where this information is available?
[14:53] <pinchartl> logitech might also implement H.264 over UVC 1.1 in the C920, I'm not sure
[14:53] <pinchartl> but that's not well-standardized
[14:53] <pinchartl> and requires specialized userspace
[14:53] <pinchartl> it should really be handled using UVC 1.5
[14:54] <Ford_Prefect> Got it, thanks
[14:54] <pinchartl> patches have been posted
[14:54] <pinchartl> I've reviewed all of them but the last one
[14:54] <pinchartl> it's "just" a matter of finding time to finish the work
[14:54] <Ford_Prefect> :)
