stream_spec is a stream specifier as described in the Stream specifiers chapter. A metadata specifier can have the following forms: Optional metadata_spec_in/out parameters specify, which metadata to copy.

Note that those are file indices (zero-based), not filenames. Set metadata information of the next output file from infile. map_metadata infile (output,per-metadata) It should leave MP4s without chapters untouched.The documentation for the -map_metadata option for FFmpeg reads: It might not be super fast for large files, as I think fb2k automatically re-writes the MP4s to optimise their layout, although I'd have to check so don't quote me on that. It only applies to MP4/M4A, and the menu item won't appear unless all the selected items in the playlist are MP4/M4A, but you can load multiple MP4s into a playlist, highlight them all, use the right click option and fb2k will strip out any chapters. There's a right click option 'Utilities/Strip MP4 Chapters'. If they have chapters, when the MP4s are loaded into a playlist, fb2k will display them as individual 'tracks'. Someone else may have a clever way to do it, otherwise.Įven though it's an audio player, foobar2000 will open MP4s containing video. I'm not sure how you'd about it using ffmpeg off the top of my head, assuming it's possible. If you only want to re-mux the MP4s with chapters and leave the rest alone.

Once you have it working you can drag and drop files onto the GUI and click 'Go'. i '' -y -threads 1 -codec copy -map_chapters -1 -movflags disable_chpl '.mp4'Ĭreating a preset for AnotherGUI is pretty easy.

To do only what you asked about and nothing more: That should strip out unnecessary metadata, set the title in metadata to match the file name and optimise the MP4 layout. i '' -y -threads 1 -codec copy -dn -map_chapters -1 -map_metadata -1 -metadata title='' -movflags faststart -movflags disable_chpl '.mp4' A command line for AnotherGUI/ffmpeg to do what you're wanting would look something like this: You might want to use it in combination with AnotherGUI to make it a bit easier. It should be do-able with ffmpeg, even if you have to process every file rather than only the MP4s with chapters.
