  • FFprobe Check Stream Link

    16 juillet 2015, par Krasic

    I am trying to use FFprobe to test if a streaming link is active or not.

    For example this is a working streaming link :

    ffprobe -loglevel quiet -show_streams rtmp://Lrmh0w.cloud.influxis.com/yoy/_definst_/185

    I do get output which mean link is active.

    However, once I change link to something not work :

    ffprobe -loglevel quiet -show_streams rtmp://Lrmh0w.cloud.influxis.com/yoy/_definst_/18555555555

    The command keeps running in background with no result.

    Is there a way to bypass this, or is there any ffprobe timeout parameter ?
    I couldn’t find it from the official website documentation.

  • What are the differences between FFmpeg and Libav ? [closed]

    16 septembre 2012, par Ken

    According to the first comment for this question, and i quote

    "Libraries with this name are provided from both the FFmpeg project
    and the Libav project, but they are mutually incompatible". So I think
    the answer depends on which libavcodec do you want to use.

    by user aland and wikipedia

    What are the differences that exist between this 2 projects ?

    I'm interested in video and audio encoding to H/X264, Mp3 and AAC with Mp4/Mkv containers ; but more importantly i would like to start with a reliable and up to date library with a permissive license and widely supported on as many platforms as possible.

    printf "file '%s'\n" ./*.mp4 > playlist.sh

    Till now i follow the demux concat official guido to ffmpeg website.
    Without result, also the following give me "more than 1000 frames duplicated between videos of the sequence"

    ffmpeg -f concat -i playlist.sh -c:a aac -b:a 384k -ar 48000 -ac 2 -c:v libx264 -x264opts 'keyint=50:min-keyint=50:no-scenecut' -r 25 -b:v 2400k -maxrate 2400k -bufsize 1200k -vf "scale=-1:432 " out.mp4
