  • MediaSPIP Init et Diogène : types de publications de MediaSPIP

    11 novembre 2010, par

    À l’installation d’un site MediaSPIP, le plugin MediaSPIP Init réalise certaines opérations dont la principale consiste à créer quatre rubriques principales dans le site et de créer cinq templates de formulaire pour Diogène.
    Ces quatre rubriques principales (aussi appelées secteurs) sont : Medias ; Sites ; Editos ; Actualités ;
    Pour chacune de ces rubriques est créé un template de formulaire spécifique éponyme. Pour la rubrique "Medias" un second template "catégorie" est créé permettant d’ajouter (...)

  • Librairies et logiciels spécifiques aux médias

    10 décembre 2010, par

    Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
    Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants. Un ensemble de librairies multimedias (x264, libtheora, libvpx) utilisées pour l’encodage et le décodage des vidéos et sons afin de supporter le plus grand nombre de fichiers possibles.

  • Organiser par catégorie

    17 mai 2013, par

    Dans MédiaSPIP, une rubrique a 2 noms : catégorie et rubrique.
    Les différents documents stockés dans MédiaSPIP peuvent être rangés dans différentes catégories. On peut créer une catégorie en cliquant sur "publier une catégorie" dans le menu publier en haut à droite ( après authentification ). Une catégorie peut être rangée dans une autre catégorie aussi ce qui fait qu’on peut construire une arborescence de catégories.

  • The screen recorder utility has failed to store the actual screen recording iOS

    31 mai 2023, par manoj

    I am getting the below issue when I run my code to record the screen on failure.

    


    An unknown server-side error occurred while processing the command. Original error : The screen recorder utility has failed to store the actual screen recording at '/var/folders/js/h2_7h9bj1fj8cn19tqcm8hnw0000gn/T/202341-30610-87cfav.bsg2u/appium_3f7703.mp4'

    


    Note : This issue is occurring during the tearDown.

    


    the code is showing stop recording is failing and this issue is occurring for only one test class

    


    public static File screenRecording(String prefix) throws IOException {
        File classpathRoot = new File(System.getProperty("user.dir"));
        String screenRec = ((CanRecordScreen) driver).stopRecordingScreen();
        byte[] screenRecord = Base64.decodeBase64(screenRec);
        String destinationPath = classpathRoot.getAbsolutePath() + "/screenRecordings/" + driver.getPlatformName()
                + " Video " + prefix + " " + new Date() + ".mp4";
        Path filePath = Paths.get(destinationPath);
        Files.write(filePath, screenRecord);
        File recordedFile = FileUtils.getFile(String.valueOf(filePath));
        return recordedFile;
    }


    


    The same thing when I run it successfully is passing in other test

    


    This is the thread that I was reffering

  • Save video using opencv with H264 codec

    31 octobre 2023, par ldiaz997

    This is beyond me and I don't know what I'm doing wrong. I have read that in order to have my video in h265 codec, I need to build opencv from source. Well, I did that, and I also did it for ffmpeg Docker ffmpeg Compiler. But I'm trying to run my application using docker, and I still can't get over the error :

    


    [ERROR:0@93.327] global cap_ffmpeg_impl.hpp:3018 open Could not find encoder for codec_id=27, error: Encoder not found
[ERROR:0@93.327] global cap_ffmpeg_impl.hpp:3093 open VIDEOIO/FFMPEG: Failed to initialize VideoWriter


    


    Dockerfile :

    I ran the command ./ffmpeg -i 57b3e3a7-ad22-469d-a7ff-cf76ba780664 -vcodec libx264 -acodec aac output.mp4 to test ffmpeg and this was the result.

    The resulting video had an h264 codec. In my opinion, the problem is in opencv. Basically this is what I do in my python code :

    


    cap = cv2.VideoCapture(video)
shoot_frames = []
while True:
    ret, img = cap.read()
    if not ret:
       break
    if some_condition:
       shoot_frames.append(img)
    if len(shoot_frames) > 41:
       out1 = cv2.VideoWriter(upload_path(name , dir), cv2.VideoWriter_fourcc(*'avc1'), int(fps), (int(width), int(height)), True)
       for shoot_frame in shoot_frames:
           out1.write(shoot_frame)
       out1.release()
       shoot_frames = []


    


    Output from print(cv2.getBuildInformation()) :

    Could someone please tell me what I'm doing wrong ?

    


  • ffmpeg concat skips frames near end of each subclip

    3 janvier 2024, par calvinusesyourcode

    So I have some video files to concat but in the resulting video the last few frames of each subclip are buggy. Imagine in the last 5 frames the first 3 frames are skipped and so at the end of each clip it seems to jitter.

    


    It should be virtually impossible for my input videos to have any differences between them, as they were all recorded on the same iPhone and all converted with the same command :

    


    command = [
            'ffmpeg', '-y',
            '-i', input_path,
            '-vf', 'scale=1080:1920',
            '-r', '30',
            '-c:v', 'libx264',
            output_path
        ]
subprocess.run(command, check=True)


    


    I have tried re-encoding instead of merely copying and adding -r 30 but that doesn't seem to work.

    


    subprocess.run(["ffmpeg", "-y", "-f", "concat", "-safe", "0", "-i", temp_textfile, "-c", "copy", output_path])


    


        subprocess.run(["ffmpeg", "-y", "-f", "concat", "-safe", "0", "-i", temp_textfile, "-r", "30", "-c:v", "libx264", "-c:a", "aac", output_path], check=True)


    


    Somewhere someone said to open in VLC and do a frame-by-frame, reporting that "the frames are actually there, just not visually when watching normally". In my case the frame-by-frame reveals the frames are indeed being skipped.

    UPDATE : I am thinking that the way I am converting my files from .mov to .mp4 is the problem. Please suggest the best way to convert from iPhone 4k 60fps .mov files to nice 1080p 30fps .mp4 files. I know I could just use handbrake but I am trying to be a man here xD. Perhaps handbrake has a View ffmpeg code for conversion.

    


    UPDATE 2 : re-encoding the videos before concat with -c:v libx264 fixes the problem... which seems weird because that is how they were originally encoded...

    j = 0
    with open(temp_textfile, "w") as file:
        while True:
            for i, video_path in enumerate(video_paths):

                time_left = desired_length - total_duration
                video_duration = duration_of(video_path)
                subclip_path = f"subclip_{i+j}.mp4"

                if (not clip_length and video_duration < time_left) or (clip_length and clip_length < time_left):

                    if clip_length:

                        subclips.append(subclip_path)
                        subprocess.run(["ffmpeg", "-y", "-i", video_path, "-t", str(clip_length), "-c:v", "libx264", subclip_path]) # added "-c:v libx264"
                        total_duration += clip_length
                        file.write(f"file '{os.path.join('..', subclip_path)}'\n")

                    else:
