files?
> Yes, firstly - FFmpeg should be able to read the clap atom prior to this
issue being fixed. I think this issue should stay open as I think there
should be a mapping between clap and PixelCrop. Should I start a new issue
that's just 'FFmpeg ignores clap atom'?
Just to clarify, I agree that this issue is jumping too far ahead and that
the clap atom support needs to come first. The request for a mapping
requires clap support. But I think the mapping is important so I'd like to
leave the ticket open.
