  • MediaSPIP en mode privé (Intranet)

    17 septembre 2013, par

    À partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".
    Le plugin Intranet/extranet, lorsqu’il est activé, permet de bloquer l’accès au canal à tout visiteur non identifié, l’empêchant d’accéder au contenu en le redirigeant systématiquement vers le formulaire d’identification.
    Ce système peut être particulièrement utile pour certaines utilisations comme : Atelier de travail avec des enfants dont le contenu ne doit pas (...)

  • ffmpeg one draw text to multiple outputs

    31 juillet 2023, par kRicha

    I've created command with ffmpeg-fluent, which connects video file with music, use shortest(video) duration, and output this to result file

    


    const newVideo = Ffmpeg(`./source/video/${category}/${dayNumber}.mp4`)
                .addInput(`./source/audio/${category}.mp3`)
                .addOption([
                    '-map 0:v:0',
                    '-map 1:a:0',
                    '-shortest'
                ]);

            newVideo.videoFilters({
                filter: 'drawtext',
                options: { ...FONT_OPTIONS, ...{ text: '1', boxcolor: 'black@1', y: 280 } }
            }).output('out1.mp4')
                .output('out2.mp4');

    if I add second output it works, but without audio and drawtext ? How could I fixe this and get draw text works on both outputs

    


  • Google Speech - Streaming Request Returns EOF Error

    16 octobre 2017, par Josh

    Using Go, I’m taking a RTMP stream, transcoding it to FLAC (using ffmpeg) and attempting to stream to Google’s Speech API to transcribe the audio. However, I keep getting EOF errors when sending the data. I can’t find any information on this error in the docs so I’m not exactly sure what’s causing it.

    I’m chunking the received data into 3s clips (length isn’t relevant as long as it’s less than the maximum length of a streaming recognition request).

    Here is the core of my code :

    func main() {
    

    
    done := make(chan os.Signal)
    
    received := make(chan []byte)
    

    
    go receive(received)
    
    go transcribe(received)
    

    
    signal.Notify(done, os.Interrupt, syscall.SIGTERM)
    

    
    select {
    
    case <-done:
    
        os.Exit(0)
    
    }
    
}
    

    
func receive(received chan<- []byte) {
    
    var b bytes.Buffer
    
    stdout := bufio.NewWriter(&b)
    

    
    cmd := exec.Command("ffmpeg", "-i", "rtmp://127.0.0.1:1935/live/key", "-f", "flac", "-ar", "16000", "-")
    
    cmd.Stdout = stdout
    

    
    if err := cmd.Start(); err != nil {
    
        log.Fatal(err)
    
    }
    

    
    duration, _ := time.ParseDuration("3s")
    
    ticker := time.NewTicker(duration)
    

    
    for {
    
        select {
    
        case <-ticker.C:
    
            stdout.Flush()
    
            log.Printf("Received %d bytes", b.Len())
    
            received <- b.Bytes()
    
            b.Reset()
    
        }
    
    }
    
}
    

    
func transcribe(received <-chan []byte) {
    
    ctx := context.TODO()
    

    
    client, err := speech.NewClient(ctx)
    
    if err != nil {
    
        log.Fatal(err)
    
    }
    

    
    stream, err := client.StreamingRecognize(ctx)
    
    if err != nil {
    
        log.Fatal(err)
    
    }
    

    
    // Send the initial configuration message.
    
    if err = stream.Send(&speechpb.StreamingRecognizeRequest{
    
        StreamingRequest: &speechpb.StreamingRecognizeRequest_StreamingConfig{
    
            StreamingConfig: &speechpb.StreamingRecognitionConfig{
    
                Config: &speechpb.RecognitionConfig{
    
                    Encoding:        speechpb.RecognitionConfig_FLAC,
    
                    LanguageCode:    "en-GB",
    
                    SampleRateHertz: 16000,
    
                },
    
            },
    
        },
    
    }); err != nil {
    
        log.Fatal(err)
    
    }
    

    
    for {
    
        select {
    
        case data := <-received:
    
            if len(data) > 0 {
    
                log.Printf("Sending %d bytes", len(data))
    
                if err := stream.Send(&speechpb.StreamingRecognizeRequest{
    
                    StreamingRequest: &speechpb.StreamingRecognizeRequest_AudioContent{
    
                        AudioContent: data,
    
                    },
    
                }); err != nil {
    
                    log.Printf("Could not send audio: %v", err)
    
                }
    
            }
    
        }
    
    }
    
}

    Running this code gives this output :

    2017/10/09 16:05:00 Received 191704 bytes

2017/10/09 16:05:09 Saving 191704 bytes
    
2017/10/09 16:05:09 Sending 191704 bytes
    
2017/10/09 16:05:09 Could not send audio: EOF

    Notice that not all of the Sends fail.

    Could anyone point me in the right direction here ? Is it something to do with the FLAC headers or something ? I also wonder if maybe resetting the buffer causes some of the data to be dropped (i.e. it’s a non-trivial operation that actually takes some time to complete) and it doesn’t like this missing information ?

    Any help would be really appreciated.

  • FFmpeg on Xcode

    4 octobre 2013, par user2741735

    I'm developing an app for ios which uses IP Camera to stream live videos to the user. I installed macports and ffmpeg using terminal on my mac. I have taken the IP Camera output and converted into .ts file using ffmpeg on terminal. Now I want the procedure to do the same using Xcode i.e. writing code in xcode to convert IP Camera output to .ts files.
    Thanks in advance.
