  • 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.

  • FFmpeg4 android Applying Overlay (watermark) taking too long

    13 janvier 2019, par Web Developer

    I’m using ffmpeg4 on android (Java) to apply overlay/watermark on the bottom left corner of the recorded video that is saved in the SD CARD.

    The video recording has maximum duration of 59 seconds. The problem that I’m facing is that I’m applying water through this command of ffmpeg4

    String[] complexCommand1 = new String[]"ffmpeg", "-y", "-i",
    "input.mp4", "-strict", "experimental", "-c:v", "libx264", "-preset",
    "ultrafast", "-vf", "movie=/water.png [watermark] ; [in][watermark] overlay=main_w-overlay_w-", "10:10", " [out]", "-s", "320x480", "-aspect",
    "2:3", "-r", "30", "-b:v", "500k",
    "output.mp4"      ;

    I’ve reduced the video resolution to 320x480 after the conversion and 480p to recorded video that is provided as input to this command but still the processing time is around 40 seconds.

    Can someone provide me workaround this to reduce this processing time.

    or what should I do to reduce this processing time. I’ve researched a lot on this and found some GitHub issues link and tried their solutions but none of them seemed to work for me.

  • FFMPEG - Long pause in av_read_frame

    5 décembre 2018, par comwizz2

    I am trying to write a service that converts a m3u8 link from youtube.

    I am loading the stream info then setting all but 1 video and 1 audio stream to AVDISCARD_ALL.

    Everything works fine except after several seconds of playing av_read_frame blocks for 30 seconds to a couple minutes.

    I’m not the best versed in ffmpeg so I’m not exactly sure what to do from here.
    Extracting one of these links into ffplay works fine it seems, but I don’t see what they may be doing differently ? I’m just hoping someone can point me in the right direction of anything to try.

    Attached is a callstack from when this is happening. I am not sure if anything here looks amiss.
