#9402: FFmpeg 4.4 - Incorrect processing of media with timecode
----------------------------------+---------------------------------------
Reporter: Andrew | Type: defect
Status: new | Priority: important
Component: avformat | Version: unspecified
Keywords: timecode | Blocked By:
Blocking: | Reproduced by developer: 0
Analyzed by developer: 0 |
----------------------------------+---------------------------------------
'''Summary of the bug:''' Media with timecode metadata is processed
incorrectly. For the sample media, which is ~6.5 seconds with basic
timecode metadata output incorrectly has a duration of 10x/fps of 1/10th
the original. This results in a file that plays "normally" for the
expected duration and then persists the final frame for about 6 minutes.
I have replicated this on multiple original files with timecode
information. It does not happen on original files without timecode
information. Unclear on the impact of other non A/V metadata/tracks.
'''How to reproduce:''' Use of "-map" is required to recreate this issue.
Example command:
ffmpeg -i Earth_6s_59-94.mp4 -loglevel error -preset medium -map 0:v:0
-c:v libx264 -profile:v main -x264opts qpmin=0 -bf 0 -pix_fmt yuv420p -g
50 -vsync 0 -tune film -map 0:a:0? -c:a libfdk_aac -b:a 128k -ac 2
-movflags +faststart EarthOut.mp4
