  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • FFmpeg Live streaming, capture card avisynth/graphedit

    19 décembre 2013, par diegonaranjo

    I´m stuck in a problem with a test doing multicast streaming from a Viewcast Osprey 700e HD using ffmpeg.
    The thing is that I´ve to use avisynth(with graphedit) for ffmpeg recognize the card. The streaming has no ending time,
    is a live channel for IPTV.
    The script is working well, but the problem is the avisynth config, because I have to specify the countframe option,
    i think this is for the duration of the clip, but I need an infinity streaming.

    The is script is :

    ffmpeg -i espnhd.avs -rtbufsize 100000k -r 30 -c:v mpeg2video -b:v 5120k -s 1280x720 -g 100 -q:v 2 -c:a ac3 -b:a 256k -f mpegts udp ://239.192.42.61:1234

    The espnhd.avs file is :

    v=directshowsource("espnhdv.GRF", pixel_type="YUV", framecount=1000000, fps=30, audio=False, convertfps=false)
    A=directshowsource("espnhda.GRF", fps=30, framecount=1000000, video=False, convertfps=false)
    AudioDub(V, A)
    loop()

    When i run the application, work fine but the streaming ends when 1000000 frames it´s encoded...
    If i dont specify framecount, ffmpeg doesn´t start with the following error, can´t determine the duration of the clip.

    Is there any way to specify an inifinity duration on avisynth ?

    The streaming stops at 1:57hs. I took the end fo the logs :

    frame=212014 fps= 30 q=4.0 size= 6957018kB time=01:57:54.13 bitrate=8056.4kbits/s dup=0 drop=211

  • PCM getting shorter duration after resample [on hold]

    12 juin 2014, par lvqier

    I have PCM file can be played with ffplay :

    ffplay -f s16le -ar 44100 -ac 1 pcm

    The file size is 88200 and duration is 1 second. I resampled it using ffmpeg :

    ffmpeg -f s16le -ac 1 -ar 44100 -i pcm -f s16le -ac 1 -ar 8000 pcm_8k

    But the size of result file pcm_8k is 15982 and duration is not exactly 1 second.

    What can I do to make the result file size to 16000 ?
