13: Hugues Fruchet: Video codecs
- Drivers that require proprietary user space components will stay out of
mainline
- Multi-format buffers could be useful here
- The hardware/firmware needs a lot of data extracted from the bitstream
next to the bitstream itself. This is a custom format, so it is OK to add a new pixelformat for each of those formats. The parsing should be done in userspace in libv4l2.
- If very little parsing is required (MPEG), then that can be done in the
kernel instead.
- Recommendation is to start simple with e.g. just an MPEG implementation.
Hoping for an RFC on this in the near future please! Thanks, Pawel
