  • ffmpeg : getting video from http page streamed to youtube

    28 novembre 2014, par M-T-A

    I’m trying to configure ffmpeg to stream to youtube from ubuntu machine.

    I have my wifi camera streaming with format ’video/x-ms-asf’ on local http page.

    Then I use these commands in attempt to stream to youtube

    VBR="2500k" # Bitrate
    FPS="20" # FPS
    QUAL="medium" #ffmpeg quality
    YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2" # URL base

    SOURCE="http://192.168.9.XX/videostream.asf?user=admin&pwd=***" # Source of video
    KEY="KEY HERE" # youtube event key

    ffmpeg \
    -i "$SOURCE"  \
    -vcodec copy -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:v $VBR \
    -ar 44100 -threads 6 -qscale 3 -b:a 712000 -bufsize 512k \
    -f flv "$YOUTUBE_URL/$KEY"

    I get this output

    Suddenly the streaming stops and the terminal hangs. I’m not sure why. Is it because the video has no audio in streaming ?
