    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.

  • How to duplicate mobile device video compression with ffmpeg

    10 mars 2021, par connor449

    I have some raw video and I am trying to compress it to mimic what it would look like if it came from a mobile device.

    


    For example, I have this information from an ipad video extracted via ffmpeg :

    


        Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709), 1920x1080, 16268 kb/s, 29.98 fps, 29.97 tbr, 600 tbn, 1200 tbc (default)


    


    How do I write an ffmpeg script that duplicates this ? I have part of it, but I'm not sure about the rest :

    


    What I have so far :

    


    framerate = 30
codec = "libx264"

ffmpeg -i {input_video} -r {framerate} -c:v {codec} -pix_fmt yuv420p -profile:v high {output_video}



    


    Specifically, how do I match these parameters :

    


        - (avc1 / 0x31637661)
    - 16268 kb/s, 29.98 fps-
    - 29.97 tbr
    - 600 tbn
    - 1200 tbc (default)


    


  • Do we need to transcode mp4 or mp3 to HLS format for streaming video/ audio on mobile app ?

    2 février 2019, par ken_vk

    We are developing a mobile app which play music and video .

    The music (.mp3) and video(.mp4) is about 5 - 20 MB . I knew we must to transcode from .mp4 to HLS format ( .m3u8) for streaming. And I still consider about transcode audio file to HLS format whether or not ?

    I have two question.

    1. Do we need transcode video (.mp4) to HLS format if the files are about 5- 20 MB.
    2. Do we need transcode mp3 file to HLS format if the files are about 5 - 10 MB ?
