  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • ffmpeg stream encoding out produce a stream shows different program on each start

    15 octobre 2018, par Ryan Philip

    I am using ffmpeg for almost one year, my stream recently started behaving badly.

    The lines on ffmpeg screen started running crazy fast when restreaming it, causing more CPU (with no encoding). I have mapped the stream to select only one stream. But the problem is even with mapping I am getting different program each time when it is played.

    Also each program it is playing for less than a minute. There is no specific error message showing on ffmpeg screen. Only the output is behaving badly.

    I even tried ffmpeg version 3.3, 3.4 and 4.0 with same results.

    It has so many resolution streams, so i selected only 33 (video) and 34 (audio), the ones with highest resolution.

    ffmpeg -i "http://insourceip/stream.m3u8" -err_detect explode  -c copy -map 0:33? -map 0:34?  -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 out/music.m3u8

    Please help me with this.

    Below is the output : the one after (No longer receiving playlist 8) start running crazy when started.

  • Playback of FFMPEG Audio Using NAudio Has Lots of Noise

    28 août 2018, par Hrethric

    I have a video that I’m trying to play back using the FFMPEG framework, and NAudio to playback the audio frames. The video plays back just fine, but when I play back the audio using a BufferedWaveProvider while the underlying audio sounds correct, it has a ton of static/noise. What’s important to note in the attached code is when the events fire off from the managed C++ class, a C# class receives the event and then grabs the latest relevant AVFrame data. This works flawlessly for video, but like I said, when I try to play back the audio I have a bunch of noise. For now I’ve hardcoded the NAudio WaveFormat settings, but they should match the video’s audio.

        ///////////////////////// C# /////////////////////////////
    

    
    // Gets the size of the data from the audio AVFrame (audioFrame->linesize[0])
    
    int size = _Decoder.GetAVAudioFrameSize();
    

    
    if (!once)
    
    {
    
        managedArray = new byte[size];
    
        once = true;
    
    }
    

    
    // Gets the data array from the audio AVFrame
    
    IntPtr data = _Decoder.GetAVAudioFrameData();
    

    
    Marshal.Copy(data, managedArray, 0, size);
    

    
    if (_waveProvider == null)
    
    {
    
        _waveProvider = new BufferedWaveProvider(new WaveFormat(44100, 16, 2));
    
        _waveOut.NumberOfBuffers = 2;
    
        _waveOut.DesiredLatency = 300;
    
        _waveOut.Init(_waveProvider);
    
        _waveOut.Play();
    
    }
    

    
    _waveProvider.AddSamples(managedArray, 0, size);
