Comment (by varenc):
I believe this is possible right now using the `filter_units` bitstream
filter. Though this isn't documented or generally well known, and an
easier to use method for this common request would be welcome.
Here's how:
{{{
ffmpeg -i input.mkv -codec copy -bsf:v "filter_units=remove_types=6"
out.mkv
}}}
Discovered this online here: https://stackoverflow.com/questions/48177694
/removing-eia-608-closed-captions-from-h-264-without-reencode which also
explains why it works. (SEI NAL units have type=6)
