  • FFMPEG settings for MP4 encoding with MPEG4 not x264

    13 May 2014, by Papapouiki

    i use this command line on Windows to encode all my videos :

    ffmpeg -i MyInputFile.wmv -c:v mpeg4 -q:v 1 -c:a libvo_aacenc -q:a 100 MyOutPutFile.mp4

    All these originals videos are in .wmv and they have a bitrate of 1200kb/s.

    I have to use MPEG4 to read the encoded videos on Android / iOS. With x264 it doesn’t work, i have a black screen and audio only.

    The command line works fine, but my output files are too big ( bigger than .wmv files, but MPEG4 is better normally ). How can i change my settings ? Select the bitrate ? i’m trying this but it doesn’t work, the bitrate is still too high :

    ffmpeg -i TestBitRate.wmv -c:v mpeg4 -q:v 1 -b 500k -c:a libvo_aacenc -q:a 100 TestBitRate.mp4

    Thank you in advance for your help. :)

  • Watch multi-stream video file while being recorded by ffmpeg

    20 January 2020, by Luke Gorrie

    I am using ffmpeg to record four 1080p video streams simultaneously and I would like to view these streams in real time while they are being recorded. Ideally I would like to view them from a separate machine, using some convenient Linux data sharing method like ssh/sshfs/..., but that is a nice-to-have. Is there a practical way to accomplish this?

    The ffmpeg recording command that I currently use is like this:

    ffmpeg \
    
  -f v4l2 -i $cam0 \
    
  -f v4l2 -i $cam1 \
    
  -f v4l2 -i $cam2 \
    
  -f v4l2 -i $cam3 \
    
  -f matroska \
    
  -map 0 \
    
  -map 1 \
    
  -map 2 \
    
  -map 3 \
    
  -c copy \
    
  $output.mkv

    My problem would be solved if I could use a command like ffplay or vlc to play one or more of the video streams, always tracking close to the end of the stream, playing more as data becomes available. I haven’t found such an option though.

    One alternative might be to have the recording ffmpeg process also tile the four 1080p videos into one 4K grid and pipe that to ffplay. Then I could at least preview on the same machine that is recording. I have not been able to work out the right ffmpeg command to do the tiling though and would appreciate an example.
