While there may be truth to that, it isn't helpful to discount objections
without a chance to substantiate them. If the person objecting choos
Please can we stop keeping score and give everyone a chance to actually get
some work done? I would love to see more objective discussions on this
topic. As others have mentioned, let's focus on why specific things are
needed so any objections can be understood and translated into code
modificati

fully briefed on, but some structural change like subtitle filtering is
needed to solve the broken state of captions support in ffmpeg.

captions. It is possible this might be a result of an oversight regarding
drop frame or non drop frame time codes with some part of the chain that

Hi Jack,
Thanks for the suggestions. Could you please tell me where I can get a
build of ffmpeg that will work with the -c:s scc command? That encoder
doesn't seem to be in the release version I am working with.
It is slightly unclear to me how your suggestion for the extract command

Greetings,
I have been absent from the list for a few years, so I would appreciate it
if someone could catch me up a bit. I am needing to extract and embed scc
