 Summary of the enhancement:

 I'd like to access error messages from demuxers and decoders output via
 ffprobe output.

 For instance a broken file can be produced via:
 ffmpeg -f lavfi -i mandelbrot -c:v mpeg2video -bsf noise=100000 -vframes
 100 -g 1 fuzzed_mpeg2video.mov

 The decoder errors can then be associated with pts and pos via:
 ffmpeg -i fuzzed_mpeg2video.mov -f null -vf showinfo -

 I'd like to decode the video with ffprobe to produce something like

 <frame media_type="video" stream_index="0" key_frame="1" pkt_pts="28160"
 pkt_pts_time="2.200000" pkt_dts="28160" pkt_dts_time="2.200000"
