The codec used is determined by the pixelformat of the capture queue. 
So if it is V4L2_PIX_FMT_H264 then H264 elementary stream would be produced.
This control would only be used for multiplexed streams - when the pixelformat
is set to V4L2_PIX_FMT_MPEG.

You mean the documentation, yes? If so it is a good idea, I could add a list of
supported video codecs for such controls.

I am not sure whether the documentation is available for download on the web.
I actually doubt it... So I will think which controls should have
more documentation.

IDC stands for 'indicator', this abbreviation is commonly used in the H264
standard.
If I understand correctly the meaning of this control is different than
V4L2_CID_MPEG_VIDEO_ASPECT and I think I should change its name to
V4L2_CID_MPEG_VIDEO_H264_VUI_SAR_IDC (AR -> SAR). This control defines the sample
aspect ratio - this the aspect ratio of the pixels. So SAR equal to 1:1 can be
used to describe a 1280x720 movie that has overall aspect ratio of 16:9.
And yes, it is a good catch that it should be a menu control.

Right, I think it's a good idea to add 'VUI' to the names of the controls you
have mentioned.

My bad, I forgot to change the documentation after we've decided to split
V4L2_CID_MPEG_LEVEL into V4L2_CID_MPEG_H264_LEVEL and V4L2_CID_MPEG_MPEG4_LEVEL.

Thanks, I have missed the Extended profile. The Stereo one was missing from my
H264 spec,
so I think I might have an outdated version.
