I need to delete some (chosen by name) metadata fields from FLV video file.

The only tool I found so far is flvmeta, but it seems it can only show and add but not remove metadata.


  • Any desktop OS, preferably cross-platform.
  • Command line or GUI doesn't matter.

Solutions like video editors that would require to re-encode a video stream don't suit.

  • Please excuse my ignorance, but what do you mean exactly with "chosen by name"? Do you mean the names of the fields themselves?

  • @nidunc yes, exactly. The names of the fields themselves.

It is possible with FFmpeg.

The following command will remove metadata fields title and author:

ffmpeg -i x.flv -c copy -metadata title= -metadata author= y.flv

Another way is to dump metadata to file, edit and reload. How To: Dump and Load metadata with ffmpeg

To inspect metadata, just run ffmpeg -i video.flv

To completely remove metadata, use -map_metadata -1 (Strip metadata from all formats with FFmpeg)
