    I have a *.mp4 video file, which is cut to a fixed size using ffmpeg, using the following commands

    


    '/usr/local/ffmpeg/bin/ffmpeg' '-y' '-ss' '00:00:00.00' '-i' '57066524-1.mp4' '-t' '00:00:05.00' '-vcodec' 'libx264' '-acodec' 'libmp3lame' '-b:v' '1000k' '-refs' '6' '-coder' '1' '-sc_threshold' '40' '-flags' '+loop' '-me_range' '16' '-subq' '7' '-i_qfactor' '0.71' '-qcomp' '0.6' '-qdiff' '4' '-trellis' '1' '-b:a' '128k' '-pass' '1' '-passlogfile' '/tmp/ffmpeg-passes6332bdc9814883qh89/pass-6332bdc98160c' '1.mp4'

    


    but I get an error saying -

  • Creating files with irregular names in Segment Demuxer

    19 novembre 2022, par Ali

    I have a video stream coming from tvheadend and I record it in 10 second chunks
This is my recording command :

    


    ffmpeg -i INPUT_PATH -f ssegment -segment_time 10 -segment_atclocktime 1 -segment_clocktime_offset 0 -write_empty_segments 1 -strftime 1 -b:v 3M -b:a 128k "TNA-%Y-%m-%d-%H-%M-%S.ts"


    


    This command works fine for me and creates the following files for me without any problem

    


      

    • TNA-2022-11-19-20-35-20

    • TNA-2022-11-19-20-35-30

    • TNA-2022-11-19-20-35-40

    • TNA-2022-11-19-20-35-50

      • 


    • TNA-2022-11-19-20-36-00

      • 


    


    But the input stream is H264 and this command records in MPEG-2 format
In the meantime, I lose the quality of the stream

    


    On the other hand, if I add the -c:v libx264 -c:a aac option, irregular files are generated.
For example :

    


      

    • TNA-2022-11-19-20-36-20

      • 


    • TNA-2022-11-19-20-36-33

    • TNA-2022-11-19-20-36-04

      • 


    • TNA-2022-11-19-20-36-14

      • 


    


    And my software can't find the files anymore

    


    The-break_non_keyframe 1option solves the problem of naming the files, but the image of the files remains fixed for a few seconds when starting

    


    Can anyone help me ?
