  • FFMPEG multiple crop on same video

    18 juin 2017, par djdan_23

    I have one .mkv that have 4 sections in time that need to be cropped.
    (Meaning that the top-bot blacks bars appears sometimes during the viewing).
    How can I do that using FFMPEG.
    I know about crop for an entire film, but using it at 4 different places on the same video, that I don’t.
    Thanks at advance.

  • Reducing the bit rate is dropping the audio stream [closed]

    19 février 2013, par user977505

    I'm a newbie to the ffmpeg, x264 commands and conversion. So please bear w/ me.

    I've a H.264 content w/ very high bit rate and I'm using ffmepg, x264 commands to reduce the bit rate. The bit rate is getting reduced but the problem is the output doesn't have the audio stream anymore.

    Here are the commands, I'm using :

    ffmpeg.exe  -i King_Maker_Leader.mp4 -pix_fmt yuv420p -vf scale=1024:576 -r 24 \
  -f yuv4mpegpipe - | x264.exe  —bitrate 1664 —demuxer y4m \
  —preset slow —ref 3 —threads 6 —thread-input —no-scenecut \
  —no-interlaced —stats King_Maker_Leader.stats —vbv-bufsize 3328000 \
  —vbv-maxrate 1996 —pass 1 —output NUL —profile main —level 3.1 —sar 1:1 \
  —tune film —keyint 96 -

    ffmpeg.exe  -i King_Maker_Leader.mp4 -pix_fmt yuv420p -vf scale=1024:576 \
    
  -r 24 -f yuv4mpegpipe - | x264.exe  —bitrate 1664 —demuxer y4m \
    
  —preset slow —ref 3 —threads 6 —thread-input —no-scenecut \
    
  —no-interlaced —stats King_Maker_Leader.stats —vbv-bufsize 3328000 \
    
  —vbv-maxrate 1996 —pass 2 —output King_Maker_Leader_generated.mp4 \
    
  —profile main —level 3.1 —sar 1:1 —tune film —keyint 96 -

    I cannot figure out what is wrong with the above commands.

    I'm attaching the partial logs from pass 2 command that show the input has two streams (video and audio) and the output has only video stream.
