  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    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.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • MediaCodec hardware decoder much slower with different server configuration ?

    19 octobre 2013, par mathieujofis

    I've been using the Android MediaCodec in order to (hardware) decode H.264 frames on my Galaxy S4 coming from a Live 555 RTSP live (real-time) stream. After changing my Live 555 server configuration from using ffmpeg (with x264) to encode frames, to using strictly x264 to encode frames, the time to decode frames with MediaCodec takes much longer. Basically, MediaCodec can't keep up with the stream, and displays the video in slow motion, getting slower and slower as time goes on. Going back to ffmpeg isn't a solution for me, because I need the ability to encode into discrete NAL units, rather than a whole frame like ffmpeg does.

    I was wondering if this was either : A) An issue with the way my server is encoding NAL units, or B) An issue with my Android client, specifically the way it is receiving and decoding NAL units.

    My encoding configuration with x264 is :

    x264_param_default_preset(&param,"ultrafast", "zerolatency:fastdecode");
    
param.i_threads = 1;
    
param.i_bframe = 1;
    
param.i_width = image_width;
    
param.i_height = image_height;
    
param.i_fps_num = 60;
    
param.i_fps_den = 1;
    
param.i_keyint_max = 10;
    

    
param.rc.i_rc_method = X264_RC_ABR;
    
param.rc.i.bitrate = 6000;
    
param.i_sps_id = 7;
    
param.b_repeat_headers = 1;
    
param.b_annexb = 0;

    My Android MediaCodec client is set up as follows :

    I receive each individual NAL unit on a separate Live 555 RTSP client thread. Each NAL is put into a queue along with its size and presentation time. A separate decoder thread grabs NALs from this queue, and if there are none available, waits until there are.

    Some notes :

    What I generally see happen is the queue starts filling up with NALs, instead of staying close to empty. So, I know that the decoder thread is not working fast enough. I don't think this is an inherent problem with decoding on an Android phone (for example, processing limitations) because it does the same thing for very low bitrates— also again, it DID work when I was using ffmpeg to encode. If I omit certain NAL units, the decoder can start to keep up. Since I'm using Cyanogenmod 10.1, bumping up the minimum CPU frequency helps, too.

    Edit :

    Here is a log of the Android client, as well as a log highlighting the garbage collector specifically—

  • NGINX RTMP convert flv to hls ?

    3 mai 2016, par MandelDuck

    I have a server that takes an rtmp stream and saves it as flv.

    Web users can view the flv video in their browser, however iPhone users can’t as it is flash

    Is there away to convert the saved flv files on the fly to hls for the iPhone viewers ?

    here is my config, Webusers access the vod application

    rtmp {
    
     server {
    
             listen 1935;
    
             chunk_size 4096;
    

    
             application live {
    
                     live on;
    
                     record all;
    
                     record_path /videos/av;
    
                     idle_streams off;
    
             }
    
             application audio {
    
                     live on;
    
                     record audio;
    
                     record_path /videos/audio;
    
                     idle_streams off;
    

    
             }
    
             application vod {
    
                     play /videos/av;
    
             }
    
             application aod {
    
                     play /videos/audio;
    
             }
    

    
     } 
    
}
