  • How to update this script to generate HLS video with different resolution streams ? [closed]

    1er décembre 2023, par Andy Z

    I have the following FFmpeg script :

    


    ffmpeg -i video.mp4 -i video.vtt \
 -map 0:v -map 0:a:0 -map 1 \
 -s:v:0 1080x1920 -c:v:0 h264 -b:v:0 500K \
 -c:a:0 copy -c:a:1 copy -c:a:2 copy -c:s webvtt \
 -f hls -hls_playlist_type vod -var_stream_map "v:0,a:0,s:0" \
 -master_pl_name video.m3u8 -hls_time 6 -hls_list_size 0 -hls_allow_cache 1 -start_number 1 \
 -hls_segment_filename "output/hls/%v/seg-%d.ts" output/hls/%v/index.m3u8


    


    Currently it only produces one 1080x1920 stream, how do I produce more lower resolution ones so it can adjust based on client bandwidth ?

    


    Also, I've noticed that it doesn't add the reference to the VTT file to the master HLS playlist ; I had to add this manually but is there a way to make FFmpeg do it for me ?

    


    #EXT-X-MEDIA:TYPE=SUBTITLES,GROUP-ID="subs",NAME="English",DEFAULT=YES,AUTOSELECT=YES,FORCED=NO,LANGUAGE="en",CHARACTERISTICS="public.accessibility.transcribes-spoken-dialog",URI="0/index_vtt.m3u8"


    


    I've tried this, but I get an argument error :

    


    ffmpeg -i video.mp4 -i video.vtt \
 -map 0:v -map 0:a:0 -map 1 \
 -s:v:0 1080x1920 -c:v:0 h264 -b:v:0 500K \
 -s:v:1 720x1280 -c:v:1 h264 -b:v:1 300K \
 -s:v:2 480x854 -c:v:2 h264 -b:v:2 150K \
 -c:a:0 copy -c:a:1 copy -c:a:2 copy -c:s webvtt \
 -f hls -hls_playlist_type vod -var_stream_map "v:0,a:0,s:0 v:1,a:1 s:1 v:2,a:2 s:2" \
 -master_pl_name video.m3u8 -hls_time 6 -hls_list_size 0 -hls_allow_cache 1 -start_number 1 \
 -hls_segment_filename "output/hls/%v/seg-%d.ts" output/hls/%v/index.m3u8

  • 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!

    Someone knows a away of embed subtitles in vídeo with FFMpeg Fluent Api in Node.JS

    Sorry my English, I’m Brazilian ! Thank’s so much
