• ffmpeg m3u8 segment file and relative path for file names

  15 mars 2013, par Luuk D. Jansen

  This must be a simple issue, but I have a difficulty with the M3U8 file created by FFMPEG as it contains the absolute path to the files, and not just the file names which I need. I am trying to be able to view the stream while it is encoded, and this seems the last hurdle.

  My FFMPEG command is (ignore the comma's) :

  ffmpeg, -i, /Users/User/Documents/Java/server/data/media/1/1/Promo-2013.mov, -dn, -y, -f, mpegts, -c:a, libfdk_aac, -strict, -2, -ar, 48000, -b:a, 128000, -s, 640x360, -c:v, libx264, -b:v, 700000, -aspect, 640:360, -r, 25, -level, 3.0, -vprofile, baseline, -flags, +loop, -cmp, chroma, -coder, 0, -me_range, 16, -keyint_min, 25, -sc_threshold, 40, -i_qfactor, 0.71, -bt, 200k, -maxrate, 700000, -bufsize, 700000, -rc_eq, 'blurCplx^(1-qComp)', -qcomp, 0.6, -qmin, 10, -qmax, 51, -qdiff, 4, -level, 30, -g, 30, -async, 2, -partitions, +parti4x4+partp8x8+partb8x8, -subq, 5, -trellis, 1, -refs, 1, -vbsf, h264_mp4toannexb, -flags, -global_header, -map, 0, -f, segment, -segment_time, 10, -segment_list, /Users/User/Documents/Java/server/data/media/1/3/prog_index.m3u8, -segment_list_flags, +live, -segment_format, mpegts, /Users/User/Documents/Java/server/data/media/1/3/segment_%05d.ts

  The resulting file is :

  #EXTM3U
  
  #EXT-X-VERSION:3
  
  #EXT-X-MEDIA-SEQUENCE:0
  
  #EXT-X-ALLOW-CACHE:YES
  
  #EXT-X-TARGETDURATION:12
  
  #EXTINF:10.005333,
  
  /Users/User/Documents/Java/server/data/media/1/10/segment_00000.ts
  
  #EXTINF:11.952000,
  
  /Users/User/Documents/Java/server/data/media/1/10/segment_00001.ts
  
  #EXTINF:10.002667,
  
  /Users/User/Documents/Java/server/data/media/1/10/segment_00002.ts
  
  #EXTINF:10.008000,
  
  /Users/User/Documents/Java/server/data/media/1/10/segment_00003.ts
  
  #EXTINF:0.266667,
  
  /Users/User/Documents/Java/server/data/media/1/10/segment_00004.ts
  
  #EXT-X-ENDLIST

  It all works perfect, but I only want e.g. 'segment_00000.ts, and not the complete absolute path, as that is of no use for live streaming. As this is a very ordinary application, I must do something wrong.

  fate : Add a —target-samples path parameter
  This allows having the samples accessible via different paths
  
  on the target and on the host.

  This code use for live streaming for send data using RTMP Wrapper.
  Not write in Socket properly because every 5 second to generate different file output file.

  This is proper way ?

  I have no idea how to get NSData in proper way.

  Please help me .
