Analyses

Analysis

The repair add the following line to the ffmpeg output: ‘Guessed Channel Layout: stereo.’ The markers to the unexisting chapter are probably removed. The error message does not prevent playing the streams. The message could possibly be also ignored.

Is it a bug in the validating software? -

Possible solutions

Recreate file with automatically selected audio and video streams

The suggestion

Copy automatically selected audio and video streams and copy ‘global metadata’ to the new file.

Execution

ffmpeg -i <input file>.MOV -c:v copy -c:a copy -map_metadata 0 <output file>.MOV

Tested with: FFmpeg 6.0

Effects

The selected audio and video streams are copied along with top-level metadata (-map_metadata 0) to the output file.

The automatic selection principles are described in FFmpeg’s documentation: https://ffmpeg.org/ffmpeg.html#Automatic-stream-selection

Justification

The file contains single audio and video streams.

Migrated files
