#5521 new enhancement

access decoder/demuxer error messages in ffprobe

Reported by: dericed Owned by:
Priority: wish Component: ffprobe
Version: git-master Keywords:
Cc: Blocked By:
Blocking: Reproduced by developer: no
Analyzed by developer: no


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

The decoder errors can then be associated with pts and pos via:

ffmpeg -i -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" best_effort_timestamp="28160" best_effort_timestamp_time="2.200000" pkt_duration="512" pkt_duration_time="0.040000" pkt_pos="768674" pkt_size="11877" width="640" height="480" pix_fmt="yuv420p" sample_aspect_ratio="1:1" pict_type="I" coded_picture_number="55" display_picture_number="0" interlaced_frame="0" top_field_first="0" repeat_pict="0">
    <side_data side_data_type="GOP timecode" side_data_size="8" timecode="00:00:02:06"/>
    [mpeg2video @ 0x7ff5cc001000] invalid mb type in I Frame at 29 1

Ooooh... This sounds very interesting and useful!

Especially considering the increasing amount of born-digital material we're receiving in A/V archives these days.
