  • Initialisation de MediaSPIP (préconfiguration)

    20 février 2010, par

    Lors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
    Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
    Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.
    Dans un premier temps il active ou désactive des options de SPIP qui ne le (...)

  • avcodec/dovi_rpu : implement support for profile 10

    23 février 2024, par Niklas Haas
    avcodec/dovi_rpu : implement support for profile 10

    Instead of the nal_prefix, this profile inside wraps the RPU inside an
    
EMDF container, as specified in ETSI TS 102 366. However, this
    
DV-specific EMDF container is restricted (by the specification) to
    
a fixed set of hard-coded parameters, which we can effecitvely treat as
    
a magic byte sequence.
    

    Validated and tested using official Dolby sample files, which
    
I unfortunately cannot share. However, there are public sample files
    
available at the merge request link below.

  • Can't Transfer .DAT (mpeg2 codec) Video to Any Other Format [closed]

    14 mai 2021, par Juan Jinping

    I have a PS2 official bonus DVD which is full of 3 hour cutscenes of MGS3. But I don't have my PS2 anymore to watch it. So I decided to transfer lossless or at least the most lossless possible. Because I am some kind of obsessed.

    


    I tried to use FFMPEG but it doesn't look it worked. At least once a minute the video goes blocky, pixelated. I tried the codes given below. I could find way more better videos on YouTube.

    


    Neither of these and their variations worked :
ffmpeg -i DEMO_3.dat DEMO_3.mkv
ffmpeg -i DEMO_3.dat -c:v libx264 -crf 0 DEMO_3.mkv

    


    I also tried it to use 3000k bitrate because it's the original bitrate of this video ffmpeg -i DEMO_3.dat -c:v libx264 -b 3000k DEMO_3.mkv

    


    Then I thought I could convert them into .png frames then reencode h264 to with "-crf 0". But frames that I extracted were blocky and pixelated too. ffmpeg -i DEMO_3.dat -r 29.970/1 %06d.png

    


    I wanted to check if my disc is broken or damaged. I downloaded the disc that I own as .iso on the internet and tried the same things but got the same results.

    


    And also the audio is not even extracted eventhough Mediainfo says there is 4 audio tracks. (probably besides English any other 3 dubs and I want them too)

    


    Long story short I want the .dat file with highest quality possible video and all audio tracks in the original mpeg2 codec or h264 codec in mkv container. You can recommend me any other program to do it or just give me code advices.

    


  • How to fix the problem of wrong colors shown in the local video window of MicroSIP ?

    25 juillet 2022, par Yadid

    I'm developing a project which is a customization based on MicroSIP in Windows. The local video window performs the video stream from Screen Capture Recorder, which is as a virtual camera and captures the screen. And the problem is the colors of the picture of the local video window are not correct. The picture I uploaded is the example of the problem, it seems like that the red and the blue are exchanged.

    
I'd tried to upgrade the FFmpeg to 5.0.1 and the SDL to 2.0.22, both are probably the latest versions, but it doesn't fix the color problem.

    
This problem also occurs when using the latest official version of MicroSIP(3.21.2).
    
source code of MicroSIP
    
source code of PJSIP (the low-level module which provides interfaces for video, audio, etc. Maybe it's the origin of the color problem)
    
And while using some of the other software which can display pictures of the virtual camera, they can show pictures fine with the correct colors, e.g. MyCam.

    
How to fix this problem ? Or which parts can I do some research on about this problem ? Any help would be appreciated.
