  • 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.

  • How to convert images to a video by the time they have been taken/saved and not by name ?

    26 avril 2019, par Xester Menia

    I have a Livestream that takes pictures every one or two seconds. Then I have a folder in which the pictures are being saved.
    Usually I would just simply take ffmpeg -start_number -i IMG_%d.JPG video.webm (I need the end format in .webm). I want to use the saved pictures to form a time-lapse to put up next to the stream. So people can see the last 24h/ 7d and 90d. So I wondered if I could code that all the pics of that time period are used and only them.
    I later want it to happen automatic, so i dont have to write the code new every day.

    Thanks for your help

  • FFmpeg C API HLS real time timestamps

    7 septembre 2022, par Robin

    I'm using the FFmpeg C API in C++ to read from a HLS stream. I need to know the real time of each AVPacket. I can extract the pts using AVPacket::pts but that is relative to the start of the stream.

    


    This is how the .m3u8 file looks :

    


    #EXTM3U
#EXT-X-VERSION:3
#EXT-X-ALLOW-CACHE:NO
#EXT-X-TARGETDURATION:10
#EXT-X-MEDIA-SEQUENCE:0

#EXT-X-PROGRAM-DATE-TIME:2022-09-07T14:01:56.612+02:00
#EXTINF:10.322561783,
1662552116.ts
#EXT-X-PROGRAM-DATE-TIME:2022-09-07T14:02:06.935+02:00
#EXTINF:10.320075936,
1662552126.ts

...


    


    The .m3u8 file contains an accurate EXT-X-PROGRAM-DATE-TIME, but how can I extract the one of the currently playing segment ?

    


    Alternatively, the file name of each .ts file is the unix timestamp in seconds. Can I extract that somehow ?

    


    If none of those are possibly, is it possible to control the exact number of preloaded segments ? I know the (approximate) segment length is 10 seconds so I could just do the following when receiving the first AVPacket :

    


    start_time = current_time - segment_count * segment_length`
start_pts = first_av_packet.pts


    


    And then to get the time of a later AVPacket, I could do :

    


    packet_time = start_time + new_packet.pts - start_pts


    


    This wouldn't give the same accuracy since the segments are not exactly the same length, but that is okay.
