  • 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 (...)

  • C# on linux : FFmpeg (FFMediaToolkit) MediaOutput..Video.AddFrame(FrameToImageData(ImageData)) causes program to exit with code 139

    19 mai 2021, par Jan Černý

    In my C# program I have instance of MediaOutput from FFMediaToolkit. It is initialized like this :

    


    MediaOutput buffer = MediaBuilder.CreateContainer(videoPath).WithVideo(new VideoEncoderSettings(width: width,
                height: height, framerate: frameRate,
                codec: VideoCodec.H264)
            ).Create();


    


    When I want to add frame to buffer I use this code :

    


    private static ImageData FrameToImageData(Bitmap bitmap) {
    Rectangle rect = new Rectangle(System.Drawing.Point.Empty, bitmap.Size);
    BitmapData bitLock = bitmap.LockBits(rect, ImageLockMode.ReadOnly, PixelFormat.Format24bppRgb);
    ImageData bitmapImageData = ImageData.FromPointer(bitLock.Scan0, ImagePixelFormat.Bgr24, bitmap.Size);
    bitmap.UnlockBits(bitLock);
    return bitmapImageData;
}

public void AddFrame(Bitmap frame) {
    buffer.Video.AddFrame(FrameToImageData(frame));
}


    


    But when code reaches buffer.Video.AddFrame(); it exits with code 139 without throwing any exception.

    


    I have two test files and only one is causing it. One is .png file 100x100 and it works fine. The other is .png file 1000x1000 and it makes program exit as soon as it reaches this method.

    


    What exit code 139 means in C# ?
    
How can I diagnose this problem when it is not throwing any exceptions ?
    
How can I fix it ?

    


    Thank you for help. If you need any more information, leave a comment and I will add it soon as possible.

  • How to know if quick sync video encoding and decoding hardware is available in your windows or linux (ubuntu) machine ?

    20 avril 2021, par jeff
      

    • I am using ffmpeg to make a video streaming web application using nodejs.

      • 


    • I want to use intel's quick sync hardware to support hardware encoding and decoding.

      • 


    • However, some machine may not support this feature so I want the software encoding and decoding as fallback

      • 


    • For this I need to know if the machine has the quick sync hardware

      • 


    • I looked it up but cant find OS api to know if the hardware api is present in the machine or not (both windows and linux)

      • 


    


  • Screen capture (video screencast) with FFMPEG with very low FPS

    20 septembre 2023, par jesusda

    I recently changed PCs, I went from having an Intel Core i5 4460 with integrated graphics card to a Xeon E5 2678 v3 with AMD RADEON RX 550 graphics.

    


    On paper, the new PC is on the order of 3 to 7 times more powerful than the old one and I can attest that this is the case in daily use, video and image editing etc. The advantage of having so many cores and threads available is palpable. In terms of games I haven't tried it because I'm not really a gamer and the few games I use are the typical free ones that come with Debian and some emulators that, honestly, already worked fine with the old PC.

    


    However there is one task that brings me head over heels for its terrible performance : video screen capture.

    


    With my old PC I was able to capture at over 60 fps at full screen while doing any task I needed to record.

    


    Even with my lenovo thinkpad x230 I am able to capture screen at over 80fps with total fluency.

    


    The command I have always used is :

    


    ffmpeg  -f x11grab -draw_mouse 1 -framerate 60 -video_size 1920x1200 -i :0.0+1680,0  -qscale 0 -pix_fmt yuv420p -c:v libx264 -preset medium -qp 0 -q:v 1 -s 1920x1200 -f matroska -threads 4 video.mkv


    


    notes :

    


    -video_size 1920x1200 -i :0.0+1680,0 y -s 1920x1200 are the dimensions and position of the region to capture (my right monitor).

    


    Notice that I even used -preset medium and software encoding, so I got very good quality even with that parameter setting and without ever going below 60 fps.

    


    What happens to me now ?

    


    The equipment is unable to capture more than 20 fps which makes any video invalid, with frame drops and not even reach 30fps, which would be the minimum required.

    


    In addition, it is quite noticeable the decrease in responsiveness of the PC as soon as I launch the command. That is, all that fluidity and smoothness that is appreciated when working normally, disappears and even moving a window from one side to another is rough and stumbling.

    


    I have tried with different parameters of ffmpeg, to capture raw, without encoding.

    


    I have tried saving the resulting video directly to RAM disk in order to avoid the possible bottleneck of writing to disk. It doesn't affect it at all.

    


    So, does anyone have any suggestions as to at least where I can dig further to find a solution to the problem ?

    I have the free amdgpu drivers (not amdgpu-pro), but I activated OpenCL just in case.
