  • Where is my ffmpeg stream getting saved to ?

    20 mars 2019, par Chris

    I’m just starting to explore ffmpeg (ultimately for use with openCV), and I’m running this command :

    root@beaglebone:/# ffmpeg -f video4linux2 -r 25 -s 640x480 -i /dev/video0 /out.avi

    At which point the camera indicator light turns on and it appears to be capturing. However when I end it with CTRL+C, the file is nowhere to be found.

    Any thoughts ?

    Full output :

    root@beaglebone:/# ffmpeg -f video4linux2 -r 25 -s 640x480 -i /dev/video0 /out.avi

  • what is recommended to use with Mpeg-dash, VBR or CBR ?

    25 août 2015, par jobin

    I need to trans code some videos to use them with Mpeg-dash, for bitrate, shroud I use variable bitrate (VBR) or constant bitrate (CBR).

    which of them work better with Mpeg-dash ?

  • What does 'dash' option in ffmpeg command do ?

    29 janvier 2020, par Hyldrean

    What is the effect or meaning of the -dash option in a ffmpeg command (extracting a track for DASH streaming) ? E.g this one :

    ffmpeg -i in.video -vn -acodec libvorbis -ab 128k -dash 1 audio.webm

    I can’t find anything about it in the ffmpeg documentation.
