  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée
    Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
    Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...)

  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • ffmpeg Bmp to yuv : Crash at sws_scale

    28 décembre 2015, par the-owner

    The context :
    I have a succession of continuous bitmap and I want to encode them into a light video format.
    I use ffmpeg version 2.8.3 (the build here), under qt5, qt IDE, and msvc2013 for win32.

    The problem :
    My code crash at sws_scale () (and sometimes at avcodec_encode_video2()). When I explore the stack, the crash event occurs at sws_getCachedContext (). (I can only see the stack with these ffmpeg builds).
    I only use these ffmpeg libraries (from the Qt .pro file) :

    LIBS += -lavcodec -lavformat -lswscale -lavutil

    It’s swscale which bug. And this is the code :

    void newVideo ()

    GdiplusStartupInput gdiplusStartupInput;

**CRASH**

    I have thougth that my bitmap wasn’t good so I have crafted a bitmap just for testing, the code was :

        uint8_t* pPixels = new uint8_t[Width * 3 * Height];
    
    int x = 50;
    
    for(unsigned int i = 0; i < Width * 3 * Height; i = i + 3) // loop for generating color changing images
    
    {
    
        pPixels [i] = x % 255; //R
    
        pPixels [i + 1] = (x) % 255; //G
    
        pPixels [i + 2] = (255 - x) % 255; //B
    
    }

    However the crash continue. Perhaps, it might prove that it’s not the bitmap (pPixels) which has a problem.

    If anyone know, why I get this bug : Maybe don’t I set one parameter well ? Or one ffmpeg deprecated function ? etc.

    The call stack is as follow : av_picture_copy() is called then av_image_copy() then _VEC_memcpy() then fastcopy_I() and crash ... The problem is not the dimensions (tmp_screenWidth/Height) ? (With av_picture_copy () could we copy a picture P1 with dim W1xH1 to a picture P2 with dimension W2xH2 ?)

    Crash at av_picture_copy() which call _aligned_malloc() then av_image_copy _VEC_memcpy() and fastcopy_I()

  • Android YouTube Live v3 rtmp streaming via ffmpeg won't show preview

    14 décembre 2017, par Ariel Yust

    Hi everyone I’m breaking my head over this issue here,
    I’m developing an Android App for streaming content from the user’s device camera (back/front) to a live streaming on YouTube.

    Problem :
    YouTube Live shows "The health is good." in (Live Streaming->Events) but there’s nothing showing in the preview... in fact when I press play it tells me "An error has occurred, please try again later".

    Why is this happening ? what could be the problem ?

    What I’m doing :
    using google’s Oauth 2.0 and google api for login.
    YouTube V3 data api’s for creating a new broadcast and stream or use an opened stream - I’m using RTMP.

    I’m opening Camera Api1 and capturing the video into a SurfaceTexture, then I encode images and audio (MIC) using Android’s MediaCodec, save a 3+- seconds *.mp4 file locally and then once the muxer is done I stream the file with ffpmeg.

  • FFmpeg pan filter error when routing stereo audio to rear channels of 5.1 output

    13 avril, par MilkyTech

    I'm trying to mix a stereo commentary track into the rear surround channels of a 5.1 audio stream using FFmpeg on Windows 10. My goal is to lower the volume of the original 5.1 movie audio, then add the stereo commentary so it plays from the rear left and right speakers (SL and SR).

    


    I've already converted the commentary to EAC3 to match the main track's codec :

    


    ffmpeg -i "CastCommentary.m4a" -c:a eac3 -b:a 640k CastCommentary.eac3

    


    Then I tried mixing them like this (from within Command Prompt, not PowerShell or a batch file) :

    


    ffmpeg -i "Tropic.Thunder.2008.UNRATED.mkv" -i "CastCommentary.eac3" -filter_complex "[0:a:0]volume=0.4[aud1]; [1:a:0]pan=5.1:FL=0:FR=0:FC=0:LFE=0:SL=c0:SR=c1[cm_rear]; [aud1][cm_rear]amix=inputs=2[aout]" -map 0:v -map "[aout]" -map 0:s? -t 600 -c:v copy -c:s copy -c:a eac3 -b:a 640k "Tropic.Thunder.5.1.commentary.test.mkv"


    


    But I keep getting errors like :

    


    [fc#0 @ ...] Error applying option 'SL' to filter 'pan': Option not found
Error : Option not found


    


    Or :

    


    [Parsed_pan_1 @ ...] Expected in channel name, got ""


    


    Or even :

    


    Output channel layout 5.1 does not match the number of channels mapped 2.


    


    I’ve tried variations of the pan syntax :

    


      

    • pan=5.1:FL=0:FR=0:FC=0:LFE=0:SL=c0:SR=c1

      • 


    • pan=5.1|FL=0|FR=0|FC=0|LFE=0|SL=c0|SR=c1

      • 


    • Wrapping in single/double

      • 


    • quotes Escaping for CMD (no caret issues in current runs)

      • 


    


    Nothing seems to work.

    


    🎯 Goal :

    


      

    • Keep 5.1 audio from the original movie (volume lowered)

      • 


    • Add stereo commentary to SL and SR

      • 


    • Output a proper 5.1 EAC3 mix

      • 


    


    🔧 System :

    


      

    • Windows 10

      • 


    • FFmpeg version : [latest static build from ffmpeg.org]

      • 


    • Running in true Command Prompt (not PowerShell)

      • 


    • Source audio : 5.1 EAC3 from a .mkv, stereo .eac3 from .m4a

      • 


    


    What’s the correct filter_complex syntax to route a stereo track to the rear channels of a 5.1 layout using FFmpeg on Windows ? Am I missing something about pan, amix, or Windows quirks ?
