1) there are changes to make to the list of channel layouts not requiring
PCE
==> AV_CH_LAYOUT_5POINT0 to AV_CH_LAYOUT_5POINT0_BACK
since the previous is
5.0(side) while the latter is 5.0 which is what is in spec (table 1.19
ISO/IEC 14496-3:200X(E) or table 42 ISO/IEC 13818-7:2004(E) )
see patch in attachment (can't be applied directly due to rebasing issues
from your initial patch)
Did you test what effect this patch has on ffmpeg (the command line
interface)
when encoding five- or six-channel aac from back and side source?
yes I did check, this patch reverts aac encoder to previous behaviour with
5.0 and 5.1 (when there was no PCE)
more accurately: 5.0 5.1 back is reverted to previous behaviour , but
5.0 5.1 side is not because it uses now PCE, which agrees with spec (no
weird channel rematrixing though); sorry for the inaccuracy.
Thank you for the explanation!
Carl Eugen
