[FFmpeg-devel] [RFC] 2 Alternative approaches for AVFrame QP Tables

[Michael Niedermayer]

[PATCH 1/4] Remove all uses of AVFrame QP tables and related fields
[PATCH 2/4] avutil/frame: Rename QP related fields so unintentional

These 2 are common in both options, they break API but not ABI so
should not be applied before the next release


[PATCH 3/4] avutil: frame Update the existing QP API

This is a rough sketch of how the existing API can cope with a much
wider range of codecs.
I did not check if this is enough to handle every codec that has QP
values but a variant if this should be able to work with all.


[PATCH 4/4] libavutil: AVEncodeInfo data structures

This is the alternative to 3/4, which is Juan De Leóns patch
which was previously posted and discussed.
IIUC there where no objections to this previously but it
was not applied by anyone.
So Maybe we can just use this. The disadvantage here that i
can see is primarely that every codec has to convert its
internal format to the one specified in the API.
In effect this would need a switch to only export
such data when needed. Because otherwise it would waste time.
