  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • Record video with Media Recorder in WEBM format

    21 mai 2017, par Matho

    I need to record two videos via media recorder and process them with ffmpeg in Android. I want to read videos via pipe in ffmpeg command string. From what I have read, I could not use 3GPP/MP4 format, because these formats contains header at the end of video. Because of it, I want to use WEBM video format, but my app is crashing, when I use webm/vp8 setting in media recorder. Ffmpeg I’m using is : com.writingminds:FFmpegAndroid:0.3.2. Could you help me please ?

  • Using node-media-server and FFMPEG, Transmuxing ends when rtmp is publishing with no errors

    8 juillet 2023, par Sina KH

    I've configured and used node-media-server library on 2 of my test servers and it works great, but when I'm trying to make it work on production, it creates directories for different qualities, but does not generate .ts and .m3u8 for them. It only creates original hls outputs.
My logs show that instantly after [rtmp publish] Handle video. and [rtmp publish] Handle audio. files, it receives [rtmp publish] Close stream. id=Y8KK9U3D streamPath=/live/15_1280 streamId=1 and [rtmp play] Close stream. id=7MC9Q65N streamPath=/live/15_1280 streamId=1
Please note that everything is the same on my test and prod servers, and with no known cause, it fails on some of my servers and works on some other ones. I've tried both deploying dockerized and not dockerized versions, with different node versions.
FFMPEG version is also the same on all systems.

  • how to output a media stream using ffmpeg ?

    26 juin 2017, par Sanduni Wickramasinghe

    I am reading a mpeg4 video stream using ffmpeg. I use some of its properties and do some processes using those properties. What I want is to play the opened video using a player like vlc. And then consequently I need to play the output video after processing in order to check whether there is a latency. Is it possible to give the video to a port. So that I can get the video as a input to the vlc player from the specific port.

    This is my code up to now. I use MV_generation method to extract features from it and to do a comparison from it.

    static int MV_generation(const AVPacket *pkt)
    
{
    
    std::vector<unsigned long="long"> vl = File_read();
    
    std::hash<string> hash1;
    
    std::ios_base::app);
    
    double x_src_val = 0;
    
    double y_src_val = 0;
    
    double x_dst_val = 0;
    
    double y_dst_val = 0;
    

    
    int ret = avcodec_send_packet(video_dec_ctx, pkt);
    
    if (ret &lt; 0) {
    
        //fprintf(stderr, "Error while sending a packet to the decoder: %s\n", av_err2str(ret));
    
        return ret;
    
    }
    
    video_frame_count++;
    
    while (ret >= 0){
    

    
        ret = avcodec_receive_frame(video_dec_ctx, frame);
    
        if (ret == AVERROR(EAGAIN) || ret == AVERROR_EOF) {
    
            break;
    
        }
    
        else if (ret &lt; 0) {
    
            return ret;
    
        }
    
        if (ret >= 0) {
    
            AVFrameSideData *sd;
    
            sd = av_frame_get_side_data(frame, AV_FRAME_DATA_MOTION_VECTORS);
    

    
            if (sd) {
    

    
                const AVMotionVector *mvs = (const AVMotionVector *)sd->data;
    

    
                int size_sd = sd->size;
    
                //outData &lt;&lt; size_sd &lt;&lt; endl;
    

    
                string str = "", str1, str2, str3, str4;
    
                for (int i = 0; i &lt; size_sd / sizeof(*mvs); i++) {
    
                    const AVMotionVector *mv = &amp;mvs[i];
    

    
                    int x_src = mv->src_x;
    
                    int y_src = mv->src_y;
    
                    int x_dst = mv->dst_x;
    
                    int y_dst = mv->dst_y;
    

    

    
                    if (x_src != x_dst || y_src != y_dst || x_src > 100 || y_src > 100 || x_dst > 100 || y_dst > 100){
    
                        str1 = to_string(x_src);
    
                        str2 = to_string(y_src);
    
                        str3 = to_string(x_dst);
    
                        str4 = to_string(y_dst);
    

    
                        str = str.append(str1).append(str2).append(str3).append(str4);
    
                    }
    
                }
    

    
                for (unsigned long long y : vl)
    
                {
    
                    // Check if any of the numbers are equal to x
    
                    if (hash1(str) == y)
    
                    {
    
                        cout &lt;&lt; "matched frame_no : " &lt;&lt; video_frame_count &lt;&lt; endl;
    
                    }
    
                }
    
            }
    
            av_frame_unref(frame);
    
        }
    
    }
    
    outData.close();
    
    return 0;
    
}
