  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • Upload FFmpeg output directly to Amazon S3

    26 octobre 2017, par user1790300

    I am using the fluent-ffmpeg library with node.js to transcode videos originally in a flash movie format to the mp3 format with multiple resolutions, 1080p, etc.. Once the transcoding is complete, I would like to move the transcoded video to an s3 bucket.

    I pull the original .flv file from a source s3 bucket and pass the stream to the ffmpeg constructor function. The issue is after the transcoding completes, how do I then get the stream of the mp4 data to send to s3.

    Here is the code I have so far :

            var params = {
    
            Bucket: process.env.SOURCE_BUCKET,
    
            Key: fileName
    
        };
    
        s3.getObject(params, function(err, data) {
    
            if (err) console.log(err, err.stack); // an error occurred
    

    
            var format = ffmpeg(data)
    
            .size('854x480')
    
            .videoCodec('libx264')
    
            .format('flv')
    
            .toFormat('mp4');
    
            .on('end', function () {
    
                //Ideally, I would like to do the uploading here
    

    
                var params = {
    
                   Body: //{This is my confusion, how do I get the stream to add here?},
    
                   Bucket: process.env.TRANSCODED_BUCKET,
    
                   Key: fileName
    
                };
    
                s3.putObject(params, function (err, data) {
    

    
               });
    
            })
    
            .on('error', function (err) {
    
                console.log('an error happened: ' + err.message);
    
            });
    

    
        });

    For the code above, where can I get the transcoded stream to add to the "Body" property of the params object ?

    Update :

    Here is a revision of what I am trying to do :

    var outputStream: MemoryStream = new MemoryStream();
    

    
        var proc = ffmpeg(currentStream)
    
            .size('1920x1080')
    
            .videoCodec('libx264')
    
            .format('avi')
    
            .toFormat('mp4')
    
            .output(outputStream)
    
            // setup event handlers
    
            .on('end', function () {
    
                uploadFile(outputStream, "").then(function(){
    
                    resolve();
    
                })
    
            })
    
            .on('error', function (err) {
    
                console.log('an error happened: ' + err.message);
    
            });

    I would like to avoid copying the file to the local filesystem from s3, rather I would prefer to process the file in memory and upload back to s3 when finished. Would fluent-ffmpeg allow this scenario ?

  • Code can not read property 1 of undefined [closed]

    I'm a very new programmer and am working on a Tdarr plugin in JS.
Everything works fine until a 4k file tries to get transcoded and it fails with this log

    Tried transcoding 4k files down to 1080p but it fails due to that undefined error. All Res 1080p and lower that I have tried work correctly

    


    EDIT : I used Console.log and got this back

  • 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.

    &#xA;

    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 :

    &#xA;

    command = [&#xA;            &#x27;ffmpeg&#x27;, &#x27;-y&#x27;,&#xA;            &#x27;-i&#x27;, input_path,&#xA;            &#x27;-vf&#x27;, &#x27;scale=1080:1920&#x27;,&#xA;            &#x27;-r&#x27;, &#x27;30&#x27;,&#xA;            &#x27;-c:v&#x27;, &#x27;libx264&#x27;,&#xA;            output_path&#xA;        ]&#xA;subprocess.run(command, check=True)&#xA;

    &#xA;

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

    &#xA;

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

    &#xA;

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

    &#xA;

    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.

    &#xA;

    Full console output :

    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.

    &#xA;

    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...
