Hi Mauro,
This PR finalizes the stateful encoder support by adding the stateful encoder
spec. It was delayed quite a bit and the main reason was how framerates should
be handled given the constraints of what existing stateful encoder drivers
implemented.
Michael, can you make a allegro patch that sets the V4L2_FMT_FLAG_ENC_CAP_FRAME_INTERVAL
flag in that driver and have it behave according to this updated spec?
Many thanks to all who contributed, with honorable mention of Tomasz who wrote
the original version of this spec.
Regards,
Hans
