• ffmpeg unrecognized option 'segment_list_flags'

  28 septembre 2012, par user1704620

  this is my first time ever posting a question on here, so bear with me. I'm using Ubuntu 12.04 and ffmpeg version 0.11.2, and I'm trying to capture a video from /dev/video0, segment the videos, and then create an m3u8 list file that lists all the segments. According to the ffmpeg documentation at http://ffmpeg.org/ffmpeg.html#Synopsis , ffmpeg supports certain options when creating a list file like '-segment_list_flags' and '-segment_list_type'. When I tried implementing these into my script, though, I just got an error that said :"unrecognized option 'segment_list_flags'" or "unrecognized option 'segment_list_type'". The actual command that I'm typing in looks like this :

    ffmpeg -f video4linux2 -s wvga -t ${CAPTURE_DURATION} -i "/dev/video0" \ 
  
    -vcodec ${VID_CODEC} -b:v 96k -flags +loop -cmp +chroma \
  
    -partitions +parti4x4+partp8x8+partb8x8 -subq 5 -trellis 1 -refs 1 -coder 0 \
  
    -me_range 16 -keyint_min 25 -sc_threshold 40 -map 0 -flags -global_header \
  
    -i_qfactor 0.71 -bt 200k -maxrate 96k -bufsize 96k -rc_eq 'blurCplx^(1-qComp)' \
  
    -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -level 30 -aspect 320:240 -g 30 \
  
    -async 2 -preset fast -crf 22 -threads 0 -sameq -f segment -segment_time ${SEG_TIME} \
  
    -segment_list ${LOCATE}${OUTPUT}_first.m3u8 -segment_list_flags +live \
  
    -segment_list_size ${SEG_LIST_SIZE} -segment_format ${SEG_FORMAT} -acodec libmp3lame \
  
    -ar 4800 -ab 64k -y "${LOCATE}${OUTPUT}%01d.${EXTENSION}"

  In other parts of my script, I obviously have those variables that you see defined, and they all work fine. I should mention that before I tried implementing the -segment_list_flags option, it did spit out a list file, but it wasn't a legal .m3u8 list file that I would need for Http Live Streaming. It just sequentially listed the different $LOCATE$OUPUT segments that I told it to create.

  The full output of my command in the terminal is this :
