Adds support for the pict_type field in AVFrame to amf_h264 and
amf_h265 simultaneously. This field is needed in cases where the
application wishes to override the frame type with another one, such
as forcefully inserting a key frame for chapter markers or similar.
Additionally this abuses AV_PICTURE_TYPE_S for marking Skip frames, a
special type of frame in AVC, SVC and HEVC which is a flag for the
decoder to repeat the last frame.
This patch has been tested with the small tool I wrote here:
https://github.com/Xaymar/ffmpeg-test. It works in both H264 and H265
and produces the correct sequence of IDR, I, P and Skip frames -
including the visual corruption that AMD's Skip frames have.
As there currently seems to be no active maintainer for amfenc files, is
there any chance of this getting merged into ffmpeg? Personally I can
work with a patch for ffmpeg, but it makes building the project a bit
more difficult (integrating make plus cross compiling tools is a bit much).
Sincerely
