  • 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 transcoding : Metallic distorsion on macOS

    10 septembre 2024, par Xavi

    I am following ffmpeg's transcoding.c example to record audio and video from my input devices into an mp4 output file with H264 and AAC as codecs. I have no issues with the video and the audio transcoding works correctly on Windows.

    &#xA;

    However, on macOS I have an issue with any input device other than the internal microphone of my laptop : the audio comes out distorted and sounding noisy and metallic (sample recording claps : https://file.io/nEn8MXHUAUQ2). I went through the input and output parameters for the filter several times, checked the values, but there must be something I'm missing. And I can't explain why it works on Windows with the same devices.

    &#xA;

    Has anyone run into a similar problem before ? Any idea where I should start looking at ?

    &#xA;

    Additional comments :

    &#xA;

      &#xA;
    1. While the Macbook's internal microphone (the only one that works) has only one channel, the other microphones I have available are stereo, so I can't say for sure that that's where the problem is.

      2. &#xA;

    2. I also tested it on a macbook mini, with the same results.

      3. &#xA;

    3. ffmpeg 6.1.1, MacOs 14.5

      4. &#xA;

    4. Input filter arguments : time_base=1/1000000:sample_rate=48000:sample_fmt=1:channel_layout=stereo

      5. &#xA;

    5. Output filter arguments : setpts=PTS-STARTPTS,aresample=48000:async=1:out_sample_fmt=8:out_chlayout=stereo,asetnsamples=n=1024

    27 avril 2021, par Jintor

    I'm streaming a .m3u8 with the latest hls.js 1.0.0 (not rc) but version of 2021-04-01...
