[feature] Add remove command

cromefire opened this issue · comments

It would be really nice if there would be a remove command similar to the remove command in hdr10plus_tool that removes dolby vision metadata from the stream. I have some files with seemingly damaged dolby vision metadata, so it would be nice to be able to remove it without needing to transcode them.

This is already supported through demux.
But maybe it could be worth having a remove subcommand as well.

As the NALUs are known, FFmpeg can be used to filter out type 62/63 as well.

You are completely right didn't notice the little notice:

Also can be used to remove the RPUs from an HEVC file.

Maybe an example with a remove heading in the README or a remove "shortcut" could be nice though. Because right now from the README I'm not quite sure whether just a normal demux already removes if or whether I need any specific flag or so, because from the description it only removes the EL, but I have files with profile 8.1, so as far as I understand there is no EL. Might just be a little deficiency in documentation.

Edit: It seems the demux command works, so basically a remove command would only need a mapping of --output to --bl-out and set --el-out to /dev/null
