[FFmpeg-devel] [PATCH 18/18] fftools/ffmpeg_enc: set AV_PKT_FLAG_TRUSTED on encoded packets

[Anton Khirnov <anton@khirnov.net>]

This allows using WRAPPED_AVFRAME encoders with loopback decoders in
order to connect multiple filtergraphs together.

Clear the flag in muxers, since lavf does not need it for anything and
it would change the results of framecrc FATE tests.
