    31 mai 2013, par

    Lorsque l’on gère plusieurs (voir plusieurs dizaines) de MediaSPIP sur la même installation, il peut être très pratique d’obtenir d’un coup d’oeil certaines informations.
    Cet article a pour but de documenter les scripts de monitoring Munin développés avec l’aide d’Infini.
    Ces scripts sont installés automatiquement par le script d’installation automatique si une installation de munin est détectée.

  • Unable to find audio stream

    18 novembre 2011, par Kurt

    I'm trying to adapt a code in order to add a sound capture feature (on a live stream), with the help of ffmpeg and directshow.

    When i try to play with ffplay the AVIsynth file, everything works perfectly i've got the audio and video. But when i open this input file by code i only find the video stream.

    The Avs file :

    V = DirectShowSource("Decklink_HDMI.grf", fps=10, framecount=1000000000, seek=false, audio=false)
    
A = DirectShowSource("Decklink_Audio.grf", fps=1, framecount=1000000000, video=false)
    
AudioDub(V, A)

    The opening code :

    ffmpeg::AVInputFormat * ifmt;
    

    
ifmt = ffmpeg::av_find_input_format("avs");
    

    
// Open input file
    
 if(ffmpeg::avformat_open_input(&pFormatCtx, filename.toStdString().c_str(), ifmt, NULL) != 0)

    When i make a variable lookout on gdb just after the opening.

    i'm looking at nb_streams in pFormatCtx->nb_streams and it's at 1
    The only stream i can find in pFormatCtx->stream is a video one. And that's why i'm not able to capture the sound.

    So i'm asking if i'm doing something wrong with my opening or if i miss something.

    Ps : I know the code shown is short but the problem appears at this very step !

    Thank you

    Kurt

    — EDIT —

    I've also noticed that when I dump the AVFormatContext the video stream got a 456x32 size.
    And i can find this very same size of the window displayed when i try to launch a corrupted script with ffplay.

    The original video format when i play the correct script with ffplay is of 1920x1080

    I think my problem is maybe deeper than the simple fact of not being able to get the audio stream.

    I'm trying to find out how to know the error message that is displayed on this 456x32 windows

    — EDIT2 —

    I Find out what is written on this image and my problem is solved, badly placed avs script an old one was is place.

    I'm ashamed.
