[FFmpeg-devel] [PATCH v3] QP tables API

[Anton Khirnov]

Hi,
a new iteration of the QP tables/video encoding parameters patches. The
set now passes FATE and could be pushed if there are no further
comments.

Changes from last iteration include:
- type is now passed to the constructor, allowing for type-specific
  per-block data to be added later
- QP type is now int32_t
- TYPE_H263 (equivalent to FF_QSCALE_TYPE_MPEG1) is gone, since it's
  semantically equivalent to TYPE_MPEG2 divided by two. So we just
  multiply by two on export and do not clutter the API with too many types.

4/9 on its own breaks FATE (since the decoders start exporting the data
in a different format), which is fixed by 5/9 and 6/9. We might want to
merge those so that every commit passes FATE. Alternatively we could
consider a compatibility layer, but given the obscurity of this feature
that does not seem to be worth the effort.

Some filters (codecview, fspp, pp7, spp, uspp), and mjpegdec, are not
converted yet. Since those have no tests, this does not break FATE.
I may convert them later or someone else is welcome to do it.

Please comment
