[FEATURE REQUEST] Filter Complex Subtitle Support

[Phillip]

[FEATURE REQUEST]

I am processing chunks of multiple videos and concating them all together,
but I have to "manually" slice and merge each video's subtitles into intermediary files and merge outside ffmpeg which is slow and annoying.

I have seen where you can overlay the subtitles - burning them - into the video stream directly but would prefer an option to include them as a togglable stream.

The idea would be something like:
[0:v]trim=start=0:end=30[v0];
[0:a]atrim=start=0:end=30[a0];
[0:s]strim=start=0:end=30[s0];

Is there some reason this doesn't already exist that I am simply missing?

when using the -ss and -t/-to main options the subtitles can be cut to the desired time segment and mapped appropriately as separate streams, just looking to be able to do the same thing inside a filter_complex filtergraph

I think this ticket is duplicate. There is already ticket for this.

My bad if so, just searched again and did not see any existing ticket referring to this.
If anyone can link me to an existing ticket, I'll of course close this one

Each example I see in that ticket is still hardcoding the subtitles though, not maintaining them as a separate stream unless I'm reading it wrong

You are reading it wrong, we do not need several tickets for same problem.
