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
