  • 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 new & delete AVPacket ?

    22 août 2014, par PatrickSCLin

    I’m working with a FFmpeg project right now, I have to store the data of AVPacket which from av_read_frame, and fill data to new AVPacket for following decoding.

    here is my problem, when I try to new & free an AVPacket, memory leaks
    always happen.

    I just doing a simple testing :

    for(;;)
    
{
    
    AVPacket pkt;
    

    
    av_new_packet(&pkt, 1000);
    

    
    av_init_packet(&pkt);
    

    
    av_free_packet(&pkt);
    
}

    Is something wrong in here ?

  • Encoding and decoding timestamps per frame using libav* into mp4

    9 mai 2019, par Kevin

    I am writing a program for recording and playing back video together with another program that is connected to a piece of hardware we sell. This other program gathers data from hardware, which contains "timestamp" counters at a fixed sampling rate.

    I am looking for a way to encode these timestamps (either raw or converted to unix) into the outputted mp4 file. The main reason being that the video stream might only start getting saved a few minutes into the hardware acquisition

    Recording :

                    timestamp
    
Main program --------------->  Video program
    
  |                                 |
    
  |                                 |
    
  v                                 v
    
Save hardware data               Save frame data
    
  and timestamp                    and timestamp
    

    
  |                                 |
    
  |                                 |
    
  v                                 v
    
Custom data format                .mp4 file

    Post processing analysis :

    for i in range(0,datalen):
    
    hardwareData, timestamp = readHardwareFile()
    
    frame, timestamp = readMP4()
    

    
    myData[timestamp].hardware = hardwareData
    
    mydata[timestamp].video = frame
    

    
analyze(myData)

    The goal being that when a I want to playback in VLC, or with OpenCV, I have access to timestamps for each frame.

    I currently save it as a separate text file with timestamp and frame #, but I’m wondering if there is a more standardized way to do this.

  • How to download a 61th minute video for 5 seconds remotely ?

    18 octobre 2015, par user186259

    As you can quickly download video from a remote part of a large video file with ffmpeg ?

    ffmpeg -ss 01:00:00 -i http://example.com/videofile.flv -t 00:01:00 -vcodec copy -acodec copy file.flv

    Here I miss the first hour of video and download 61th minutes. It takes 20 minutes. Time of the operation = end of video and splitting it locally.

    How can I speed up the process ?
