I have been looking for months, on and off. Is there any place that
shows how to form a working ffmpeg command line? I'm trying to figure
out how to use a fieldmatch filter.
There is clear documentation explanation for using this and other filters.
Well, there's no examples and no top-level templates showing how to form
a command line, at least none that I've found.
What I've concluded from what I've read (and seen on this list):
'ffmpeg [gen_opts] [in_opts] -i <infile> [out_opts] <outfile>'
And I've read about filter graphs of course, but it's awfully cryptic
and there's no use examples. I know that filter invocation involves
operators such as '[x:y]' but I've not figured out what they symbolize
and how to use them in a command line -- I've tried dozens and dozens of
hacks.
The wiki just shows pieces of things, not how to form a command.
Of course, if you have a link, that would suffice. I'm awfully frustrated.
Regards,
Mark.
