Hi, I am trying to generate a mpegts stream with live DVB subtitles.
I have managed to create DVB subtitles by doing some tricks with python + spumux + ffmpeg and I can finally get a dvbsub file that contains subtitles. If I mux dvbsubtitle file into a mpegts stream everything seems fine, just a little bit out of sync. ffmpeg -re -f lavfi -i testsrc=size=1280x720:rate=30 -f mpegts -i dvbsub.sub -vcodec h264_nvenc -g 10 -scodec dvbsub -f mpegts output.ts -y My problem is when I try to generate live DVB subtitles: I have tried to put dvbsub.sub input in loop mode: ffmpeg -re -f lavfi -i testsrc=size=1280x720:rate=30 -stream_loop -1 -i dvbsub.sub -vcodec h264_nvenc -g 10 -acodec aac -strict -2 -scodec dvbsub -f mpegts output.ts -y and generate new dvbsub.sub for each "chunk" of subtitles, but ffmpeg doesn't seems to mux those new subtitles in the right way and "repeats" the first ones in a "random" way. Any suggestions about how to generate live subtitles and mux them in a live way into de the mpegts stream?
