[FFmpeg-devel] [PATCH v4 0/7] APV support

[Mark Thompson]

v4: minor changes from previous version reflecting review comments.

This seems to be converging so will consider pushing soon and then working on top of it (the patches from Dawid Kozinski for ISOBMFF support will also apply on top of this).

My next thoughts here are around improving the entropy decoding because with the optimised transquant it is taking >90% of the decoder time at the highest bitrate bands.

Thanks,

- Mark
