Subject: [PATCH 0/3] MPEG-2 stateless API cleanup
Date: Tue, 29 Sep 2020 20:39:06 -0300	[thread overview]
Message-ID: <20200929233909.6935-1-ezequiel@collabora.com> (raw)

Hello everyone,

Following the H.264 API cleanup, and with all the learning lessons
from it, here's a revisit on the MPEG-2 API.

The biggest changes are:

* Drop slice size and offset parameters, given the API doesn't
  seem to be designed to work per-slice.

* Convert all the 1-bit syntax elements from structure fields
  to bits in a bit field flags field, following the other codec APIs.

* Split the sequence, picture and slice headers to separate controls.

This is build tested only, I haven't yet modified the existing
Ffmpeg-based implementation, as I'd like to have some consensus first.

Reviews and feedback are appreciated!

Thanks,
Ezequiel
