Stateless video decoders require explicit codec specific metadata
derived from video bitstream parsing.
This plugin aims to silently convert the user provided video bitstream
to a parsed video bitstream, ie the video bitstream itself + additional
parsing metadata which are given to the driver through the V4L2 extended
control framework.
This plugin can support several codec dependent parser backends, enabling
of the right parser is done by intercepting the pixel format information
negotiated between user and driver (enum_fmt/try_fmt/get_fmt/s_fmt).
This patchset provides a MPEG-2 parser backend using GStreamer
codecparsers library.
It has been tested with STMicroelectronics st-delta kernel driver.
