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? -

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
~~~~~~~~~~~~~~
