[FFmpeg-user] MP4 concat filter with subtitles

[Gojko Adzic]

Hi,

Is there a way to concatenate multiple files while joining subtitles?

I'm currently using the concat filter (need to re-encode the inputs) and
naively
tried to use concat=n=2:v=1:a=1:s=1, which failed as the concat filter
doesn't seem to like the s output.

thanks in advance!
