v4l2src

[Chuck Crisler]

Thank you for the prompt reply. Your samples show using a caps filter,
don't they? Does that cause the source filter to actually capture in the
desired format, or does it convert what is captured to that format, or
either, depending on the capabilities of the actual device? You said that
mpeg is generally YUV. Does that mean that it won't contain H264? Can't you
encapsulate H264 in mpegts?
