• Can OMXPlayer show SRT subtitles embedded in a mp4 file ?

  4 février 2023, par Eddy Sorngard

  Is there a way to get OMXPlayer to show the embedded subtitles in foo.mp4 without first extracting the subtitles with ffmpeg to foo.srt, and without hardcoding the subtitles into foo.mp4 ?

  I use git to track *.ass subtitle files.
  Here is example of *.ass file :

  After commit I burn subtitles into video :

  ffmpeg -i video.avi -vf "ass=subtitle.ass" out.avi

  My goal is to show commit date for 10 second at the start of movie. This should be done automatically.

  1) It can be easily done with by modifying subtitle.ass itself, but I can’t do it after commit and there are other reasons.

  2) It can be done by ffmpeg from command line : How to use ffmpeg to add a text to avi video ?

  Problem is that in this case text will be shown for the whole lenght of movie.

  3) I can copy *.ass file to temporary directory, insert date, render and delete *.ass file.

  Is there a simpler way ?

• Subtitles in video with NodeJS and FFMpeg Fluent Api

  23 juillet 2016, par João Santiago

  I try to include subtitles (srt) in na vídeo stream with Node JS and FFMpeg... I’m try this away :

   var command = ffmpeg(file.createReadStream())
  
      .input("C:\\code.srt").videoCodec('copy')
  
    .videoCodec('libvpx').audioCodec('libvorbis').format('webm')
  
    .audioBitrate(128)
  
    .videoBitrate(1024)
  
      .inputFPS(75)
  
    .outputOptions([
  
      '-deadline realtime',
  
      '-error-resilient 1'
  
    ])

  And I got this error :

  [Error: ffmpeg exited with code 1: Encoder (codec none) not found for output stream #0:2

  Try this too, with —vf subititles= of documentation of FFMpeg and I’ve got this error :

  var command = ffmpeg(file.createReadStream())
  
        .videoCodec('libvpx').audioCodec('libvorbis').format('webm')
  
        .audioBitrate(128)
  
        .videoBitrate(1024)
  
          .inputFPS(75)
  
        .outputOptions([
  
          '-deadline realtime',
  
          '-vf subtitles=C:\\code.srt',
  
          '-error-resilient 1'
  
        ])
  
  
  
  Error: ffmpeg exited with code 1: Error opening filters!
