Rematrixing supports up to 64 channels. However, there is only a limited number
of channel layouts defined. Since the in/out channel count is currently
obtained from the channel layout, for undefined layouts (e.g. for 9, 10, 11
channels etc.) the rematrixing fails.
This patch changes rematrix i

Of course, I will update the patch and send it out shortly.
Using in.ch_count should be ok. The relevant check is in swresample.c:292,
so we should never reach that code if the in.ch_count is 0.

This could negativly affect the performance of the changed inner loop
have you checked that

And add it to the list of configurable components in Makefile, so changes to
the file will be tracked and the usual warning to suggest re-running configure
will be shown.

Hello
Patch in attach add support for prores 444 profile in AW prores encoder
Need to be apply after patch in discussion "avcodec/proresenc_aw
improvments"
Speed (from prores 422 HQ file -> Prores 444)
./ffmpeg -i prores422hqfile.mov -pix_fmt yuv444p10 -c:v prores -an

Patch 002 : change the header of the output file only, not the compress
data.
Patch 003 : change the output file mainly for near uniform bloc, where the
low scale quantif value where used.
But IMHO is better by default to be close to official
Hi!
Attached patch fixes a warning on ppc32:
libavformat/mov.c: In function ‘mov_read_saio’:
libavformat/mov.c:6207:45: warning: assignment from incompatible
pointer type [-Wincompatible-pointer-types]

Hello,
Patch in attach improve some part of the prores_aw encoder.
001 : use scantable in prores_data instead of a duplicate one.
002 : use for the frame header, primaries, transfert, colorspace like in
proresenc_ks
avoid color shift on some software (update fate test)
003 : change qp start value
