Tomasz Figa 051f8d2d86 media: docs-rst: Document memory-to-memory video decoder interface
Due to complexity of the video decoding process, the V4L2 drivers of
stateful decoder hardware require specific sequences of V4L2 API calls
to be followed. These include capability enumeration, initialization,
decoding, seek, pause, dynamic resolution change, drain and end of
stream.

Specifics of the above have been discussed during Media Workshops at
LinuxCon Europe 2012 in Barcelona and then later Embedded Linux
Conference Europe 2014 in Düsseldorf. The de facto Codec API that
originated at those events was later implemented by the drivers we already
have merged in mainline, such as s5p-mfc or coda.

The only thing missing was the real specification included as a part of
Linux Media documentation. Fix it now and document the decoder part of
the Codec API.
