  • 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 (...)

  • ffmpeg hw accel sample code or tutorials ?

    19 décembre 2013, par user3117740

    I had wrote a video player based ffmpeg, now it is working fine. but high CPU usage up to 60% when decoding some 1080p video files, such as wmv/rmvb/mkv formats (my config : I5,8G,HD7850).

    after do many searchs, I know the "hw accel", and I found the ffplay.c has enabled it. But the source code of ffplay.c is too large and too complex to read, who had simple code can teach this ?

    PS : I found some codes of DXVA2 for ffmpeg, add it to my project and build ok. I debug it, no problem, working fine, but the CPU usage only a few decrease, about 10%...

  • Static Compilation of FFmpeg with x264 support

    17 février 2014, par b1izzard

    Based on the Tutorial, I tried to build the latest FFmpeg binary with x264 support for Command line execution using Android-ndk-r9c.

    I had built the x264 using the below script :

     #!/bin/bash        
    

    

    
PREBUILT=/home/blizzard/bin/android-ndk-r9c/toolchains/arm-linux-androideabi-4.6/prebuilt
    
                PLATFORM=/home/blizzard/bin/android-ndk-r9c/platforms/android-9/arch-arm

            make
    
            sudo make install
    
            sudo ldconfig

    For building FFmpeg I had used the below script :

    Use sub-pixel accuracy prediction non-RD mode

    This commit builds the actual prediction block in sub-pixel accuracy
    and uses which to calculate SAD for non-RD mode decision. In the trail
    run on pedestrian_area at 1080p, rtc speed -7 runtime goes from
    23495 ms -> 25107 ms (7% slower). The compression performance is
    improved by 20.57% for rtc test set.
