Improves compatibility with Resolume products by adding an additional
hashtable for DXT color+LUT combinations, and padding the DXT texture
dimensions to the next largest multiple of 16. Produces identical
packets to Resolume Alley in manual tests.

Hi,
I'm Dariusz from Samsung Electronics, you can know me from last VDD in
Korea, I was presenting APV.
I'm glad that Mark created native APV decoder. As you might know we're also
working on APV implementation for FFmpeg.

I considered it but adding support to substitute in padding seemed
like a rather large refactor.

We want to warn once each time reading is resumed but only for the first

This patch introduces PCM dumping support between AVFilter links, intended for
audio debugging.
It adds a configure-time option `--dumpdir=PATH` to specify the output

Two commands are exposed to control dumping:

Hi,

Perhaps I can add a `mode` enum parameter to the FFHashtableContext to
control behavior? Then we can benchmark different behaviors on a
per-use-case basis.

Both the audio and video sidx boxes at the end point to a range corresponding
to the final mdat atom. Since there is no mfra following the final mdat when
recording crashes, current logic sets the flag frag_index.complete flag on the
penultimate sidx atom since it points to the end of the file.
