    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.

  • ffmpeg VBR -> CBR conversion and streaming of MPEG-2 TS video files

    26 juillet 2017, par Georgе Stoyanov

    I am trying to convert a source VBR SPTS MPEG-2 TS file into CBR using ffmpeg. The code I am using is the following :

    #!/bin/bash
    

    
pkill ffmpeg
    

    
ffmpeg \
    
        -re -i source.ts -c copy \
    
        -muxrate 18000K \
    
        -f mpegts \
    
        udp://destination_ip:1234?pkt_size=1316

    The source VPID bitrate is 10Mbps and the APID is 296Kbps. So according to my understanding this code should deliver 18Mbps CBR where the difference between the muxrate and the bitrate of all the PIDs is filled with null packets.

    The problem is that the output is far from perfect. The overall bitrate is semi-CBR at best. It ranges between 12Mbps and 15Mbps and I see a lot of PCR accuracy and PCR repetition errors along with CC errors both on the VPID and APID.

  • Installing Software in Linux Ubuntu - shotdetect for detecting video shots

    17 octobre 2015, par kanchan

    I have got many errors while installing shotdetect software. some errors were because of the dependencies and that is resolved.Its able to configure perfect but "make" i.e., running make file is throwin this error.
    error : ffmpeg/avcodec.h No such file or Directory
    ffmpeg/avformat.h No such file or Directory

    May be its because ffmpeg or shotdetect software versions are different. I tried re-installing the latest (and old ffmpeg) ones but not able to find ffmpeg folder in my /usr/include/ and that is why there is no such file "ffmpeg/avcodec.h".
    Please help.

    please give the perfect command for to do image animation effects.

    public static String[] cmdCreateVideo(int frame,String videoSource, String outPut){
    
    float duration_frame=1.0F;
    
    if (frame<= 20) {
    
        duration_frame = 1.0F;
    
    }else {
    
        duration_frame = 0.6F;
    
    }
    
    String str5 = "-framerate 1/" + duration_frame + " -start_number 0 -i " + videoSource + " -vcodec mpeg4 -q:v 3 -r 20 -vf scale=480x800 " +outPut;
    
    return str5.split(" ");
    
}

    this is my command to create video from images ,but i want to add image trasition effect between two images.
