• Ffmpeg hardcode a list of subtitles to a video

  23 décembre 2022, par TheRedM

  I couldn't figure out how to stream a list of subtitles to an rtmp server, the idea is I have a list of mp3 files and a list of subtitles, each mp3 has its own subtitle, what i was trying to do is stream both lists and a video background (with the subtitles hardcoded to the video background) i tried a bunch of options, I managed to output them as an mp4 video with the subtitles softcoded but I couldn't figure out how to stream them with the subtitles hardcoded, my lists goes as follow :

  


  mp3s

  


  
file 'path/to/audio1.mp3'
file 'path/to/audio2.mp3'
file 'path/to/audio3.mp3'
file 'path/to/audio4.mp3'
...


  


  subtitles

  


  file 'path/to/audio1.srt'
file 'path/to/audio2.srt'
file 'path/to/audio3.srt'
file 'path/to/audio4.srt'
...


  


  And of course the video background as input

  


  I was thinking about using a while loop but that's going to call ffmpeg for every mp3 which is inconvenient for a live stream.

  


  With some more digging I come up with this code :

  


  ffmpeg -f concat -safe 0 -i audioList.txt -f concat -safe 0 -i subtitleList.txt -i background/video.mp4 -filter_complex "[1:v][0:a]overlay[v1];[v1][2]subtitles[v2]" -map "[v2]" -c:a aac -b:a 128k -c:v h264 -b:v 3000k -f flv rtmp://stream/key


  


  I'm not sure if the subtitles will be hardcoded because the script didn't work at all, it seems right to me but i'm getting this error

  


  [Parsed_subtitles_1 @ 0xaaaacf52fb60]
No filename provided!
[AVFilterGraph @ 0xaaaacf5f6370] Error initializing filter 'subtitles'
Error initializing complex filters.

  I re-checked subtitleList.txt It seems right.
