If this happens, it's a sign of parsing issues earlier in the process, or misuse by the calling module. Prevents writing invalid bitstreams. Reviewed-by:

Previously, prompeg_write() would only report to caller that bytes we written when a FEC packet was actually created. Not all RTP packets are expected to generate a FEC packet however, so this behavior was causing avio to retry writing the RTP packet, eventually forcing the FEC state machine to send a FEC packet erroneously (and so breaking out of the retry loop). This was resulting in incorrect FEC data being generated, and far too many FEC packets to be sent (~100% FEC overhead). fix #7863 Signed-off-by:David Holroyd <david.holroyd@m2amedia.tv> (cherry picked from commit ffc1208266c2890a1b0e2391e0a536fe9698e69c)

It is a constant known at codec init, so set it in ff_frame_thread_init(). Also, only set it for video, since the meaning of this field is not well-defined for audio with frame threading. Fixes availability of delay in callbacks invoked from the per-thread contexts after 1f4cf92c. (cherry picked from commit 6943ab688d0c75dbab3222b5b80457ab72a0615f)

current_picture was not writable here because a reference existed in at least avctx->coded_frame, and potentially elsewhere if the caller created new ones from it. Signed-off-by:

This causes regressions in end to end timestamps with mp3s and ffmpeg. The revert is to avoid this regression in the 4.3 release See: [FFmpeg-devel] [PATCH] Don't adjust start time for MP3 files; packets are not adjusted. This reverts commit 460132c9.
