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 ------------------ .. contents:: :local: 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 .MOV -c:v copy -c:a copy -map_metadata 0 .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 ~~~~~~~~~~~~~~ No suggestion determined.
