  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • NaCl with FFmpeg, avformat_open_input return -5 and -1052488119 [duplicate]

    30 juillet 2013, par Jar

    This question is an exact duplicate of :

    I'm trying to port FFmpeg into my NaCl module.

    So far, my module linked ffmpeg and SDL libraries.

    It already can play YUV format video which is directed load into memory and copy into YUVOverlay buffer (it's very easy).

    Now, I want to use ffmpeg to decode video, but when I call the function avformat_open_input it returns -5 when input is URL string, such as rtmp:// or mmsh:// ; it returns -1052488119 when input is file name, such as /saved/tmp (I mount the file system - html5fs).

    There are some questions :

    1. What means of -5 and -1052488119 ?
    2. If file can't open by avformat_open_input, is it possible the input type is from buffer not from file name or url string ?

    If I'm not clearly about my question or description, you can tell me.
    If you are doing the same thing or having the same problem, we can discuss together.

    Thanks,

  • How to get rtp(javacv ffmpeg) stream from VLC as client

    15 avril 2015, par Sezertt

    I am trying to play rtp stream from vlc player which I created using javacv. Here is the code :

            FFmpegFrameGrabber frameGrabber = new FFmpegFrameGrabber("rtsp://10.6.0.147:554/ufirststream");
    
        frameGrabber.start();  // First I take another stream 
    

    
        FFmpegFrameRecorder frameRecorder = new FFmpegFrameRecorder("rtp://239.31.31.69:4433", frameGrabber.getImageWidth(), frameGrabber.getImageHeight());
    

    
        frameRecorder.setFormat("rtp");
    
        frameRecorder.setPixelFormat(AV_PIX_FMT_YUV420P);
    
        frameRecorder.setVideoCodec(AV_CODEC_ID_MPEG2VIDEO); <-- AV_CODEC_ID_H264
    
        frameRecorder.setFrameRate(25);           
    
        frameRecorder.setVideoBitrate(1024); <--1024*1024*2            
    
        frameRecorder.start();
    
        while (true) {
    
            frameRecorder.record(frameGrabber.grab()); //grab from stream, stream with rtp
    
        }

    If I choose my codec as AV_CODEC_ID_MPEG2VIDEO I can play the stream from VLC using rtp ://239.31.31.69:4433 with open network.

    If I increase the quality using setVideoBitrate(1024*1024*2) the stream lags too much and if I decrease the quality is so bad.

    I want to use AV_CODEC_ID_H264 as my codec to fasten things with better quality but i can’t play the stream from VLC getting error :

    SDP required A description in SDP format is required to receive the RTP stream. Note that rtp :// URIs cannot work with dynamic RTP payload format (96).

    I tried to get sdp using wireshark and then I realized rtp stream doesn’t have sdp :) so I tried to create my own sdp like this

    c=IN IP4 239.31.31.69
    
m=video 4433 RTP/AVP 96
    
a=rtpmap:96 H264/90000

    and this

    v=0
    
c=IN IP4 239.31.31.69
    
a=recvonly
    
t=0 0
    
m=video 4433 RTP/AVP 99
    
a=rtpmap:99 H264/90000
    
a=fmtp:99 packetization-mode=1;profile-level-id=42c01e;sprop-parameter sets=Z0LAHukBQHsg,aM4G4g==;

    but both seems to fail similar to this

  • FFMPEG working Xcode project

    26 avril 2015, par AlEX

    Someone has a working FFMPEG Xcode Project ?
    i’d like to debug it and understand how it works..

    2 days left for correction syntax of main sources (cmdutils*, ffmpeg*).. As a result : Xcode has no error in source code FFMPEG, but.. say that error in (!) main.m : #import <cocoa></cocoa>Cocoa.h> : "Timed out waiting to acquire lock file for module ’Cocoa’"

    And how to build ffmpeg, ffplay, ffserver as a library and not as executable ?
