  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • What is the structure of AVPacket::data ?

    16 juin 2017, par Sanduni Wickramasinghe

    I’m extracting data of an MPEG data packet using data member variable which is inside AVPacket structure.

    AVDictionary *options = NULL;
    
AVFormatContext *s = avformat_alloc_context();
    
AVPacket *pkt = new AVPacket();

    Now I can read data as a bit stream. But I want to know the structure of data that I am reading. I mean, by separating it in to I,P and B frames.

    int ret = avformat_open_input(&s, url_ref, NULL, NULL);
    

    
data = pkt->data;

  • Black overlay appears when merging a transparent video to another video

    13 juin 2012, par RakeshS

    This is what I have done so far :

    Command to create a transparent PNG image :

    convert -size 640x480 -background transparent -fill blue \
    
-gravity South label:ROCK image1-0.png

    Command to create a transparent video :

    ffmpeg -loop 1 -f image2 -i image1-0.png -r 20 -vframes 100 \
    
-vcodec png -pix_fmt bgra mov-1.mov

    (as per this post) - I expect this video to be a transparent video.

    Command to overlay a video with another :

    ffmpeg -i final-video.mov -sameq -ar 44100 \
    
-vf "movie=mov-1.mov [logo];[in][logo] overlay=0:0 [out]" \
    
-strict experimental final-video.mov

    Above commands works perfect and I have not faced any problem, but I don't get what I expect which is kinda watermarking effect, I want mov-1.mov to be transparent with final-video.mov.

    Questions :

    1. Is there any way to verify if the generated video is transparent ? other than merging ?
    2. Not sure why the above mov-1.mov is not transparent when it is merged with final-video.mov, any info to solve this problem would be great.

    Please help.

  • Pydub wont find ffmpeg/ffprobe on "portable" installation

    22 juin 2021, par Lukas Neumann

    Basically what im trying to achive is, having a ffprobe/ffmpeg in a static folder that is not in the PATH.

    


    What ive tried to do :

    


    pydub.AudioSegment.converter = "C:\\xxx\\ffmpeg.exe"                    
pydub.AudioSegment.ffprobe   = "C:\\xxx\\ffprobe.exe"
myfile = Path("C:\\xxx\\sample.mp3")
print(os.path.isfile(myfile)) #True


    


    But now,

    


    sound = pydub.AudioSegment.from_mp3(myfile)


    


    Still outputs :

    


     Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work
 FileNotFoundError: [WinError 2] The system cannot find the file specified


    


    Otherwise commands like :

    


    C:\xxx\ffprobe.exe --help


    


    Work fine in the cmd.

    


    What could be my mistake ?

    


    Any help is appreciated !
