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!

gojko

Because libavfilter currently does not have implemented processing of
subtitles like video/audio.

Thanks for responding so quickly. are there any other workarounds? I don't
mind running ffmpeg several times if necessary.
