    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.

  • avconv transcoding drops frames

    8 mars 2015, par ziggestardust

    I have a logitech c920 that I can send perfectly fine to a wowza server with this with excelent results :

    ./capture  -o -c0|avconv -f alsa  -b 128k -i hw:1   -re -i - -vcodec copy  -ar 44100 -bufsize 1835k   -map 0:0 -map 1:0 -f flv rtmp://myhost/live/streamname

    (capture program is from here : http://derekmolloy.ie/streaming-video-using-rtp-on-the-beaglebone-black/ I’m not using beaglebone, but his capture software runs excellent on my debian pc)

    However, I want to store the h264 stream from the camera down to disk, and later send it in a lower resolution with avconv so I’m playing with libx264

    It seems I can’t even do this without getting drops :

    ./capture  -o -c0|avconv -f alsa  -b 128k -i hw:1   -re -i - -vcodec libx264  -ar 44100 -bufsize 1835k   -map 0:0 -map 1:0 -f flv rtmp://myhost/live/streamname

    This is what avconv ’-v verbose’ shows :

    I have tried with ffmpeg but it gives same result with dropped frames.

    Any help appreciated

  • Get_iplayer not converting to MP4 [closed]

    16 juin 2022, par PhilDunford

    get_iplayer

    


    I know that this is an old piece of code, but it still does a great job.

    


    In the last week or so it's stopped converting the .ts files to .mp4. I've seem this mentioned elsewhere, but no solution. I think the key line among many error messages may be 'unable to determine ffmpeg version'.

    


    I assume the BBC has done something to break it (this has happened many times before).

    


    Needs someone much cleverer than me to fix it. Does anyone still update the code or know a work around ?
