Greetings!
Have mercy ...
I have one input file that contains a single video track and two audio
tracks. I discard the unwanted audio
track with the following command:
ffmpeg -i input.mp4 -map 0:v -map 0:a:1 -c copy tmp.mp4
From an input file containing one subtitle track, I add the subtitle
with the following command:
ffmpeg -i tmp.mp4 -i input.srt -c copy -c:s mov_text
-metadata:s:s:0 language=eng output.mp4
Is there a way to consolidate these two commands into a single
command? In particular, adding in the
subtitle. I am using "ffmpeg version 4.4.5".
If you are so inclined, I would be more than amenable to criticisms as
to how I am going about my business. I
constantly strive for best practices but after a lot of trial and
error I just settled upon the above.
Seems I can do better.
With sincere appreciation and gratitude for this list. Thank you.
First, upgrade your ancient FFmpeg to the current 7.1 version
Then as you already are familiar with the usage of map, use that to
incorporate everything into a single command like this:
ffmpeg -i input.mp4 -i input.srt -map 0:v -map 0:a:1 -c:a copy -map
1:s:0 -c:s mov_text -metadata:s:s:0 language=eng output.mp4
Haven't tested this but should work.
