6 Codec Interface
9 A V4L2 codec can compress, decompress, transform, or otherwise convert
10 video data from one format into another format, in memory. Typically
11 such devices are memory-to-memory devices (i.e. devices with the
14 A memory-to-memory video node acts just like a normal video node, but it
15 supports both output (sending frames from memory to the codec hardware)
16 and capture (receiving the processed frames from the codec hardware into
19 for both capture and output to start the codec.
21 Video compression codecs use the MPEG controls to setup their codec

29 Memory-to-memory devices function as a shared resource: you can
30 open the video node multiple times, each application setting up their
31 own codec properties that are local to the file handle, and each can use
33 the codec and reprogram it whenever another file handler gets access.
34 This is different from the usual video node behavior where the video
