    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;

  • Why do I use the header file/library + ffplay.c download from the official website of ffmpeg to make the player worse than the official ffplay ?

    15 juillet 2020, par fredirty2017
      


    1. I am use win10 system with a "http_url_mp4" in hand, the MIME of this file is :
video/mp4 ; codecs="mp4a.40.2,avc1.640020" ; profiles="isom,mp41,mp42".

      


      2. 


    2. I downloaded the header files, libraries, dlls, source code from https://ffmpeg.zeranoe.com/builds/ ,then :

      


      3. 


    3. Run offical "ffplay http_url_mp4", audio and video viewing is normal ;

      


      4. 


    4. I used VS2017 (the project has no special settings) to compile and link the fftools/ffplay.c，fftools/cmdutil.c and the included header files(libavcodec/libavutil and so on), libraries(such as avcodec.lib, avdevicelib, etc.), dlls(avcodec-58.dll / avformat-58.dll...), then run "myffplay http_url_mp4", The playback is stuttering, debugging found av_read_frame relative The processing cost more time, the calling frequency will be lower.

      


      5. 


    5. i found config.h only line '#define FFMPEG_CONFIGURATION "—enable-gpl"', but offical ffplay cmdline shows :
'—disable-static —enable-shared —enable-gpl —enable-version3 —enable-cuda —enable-cuvid —enable-d3d11va —enable-dxva2 —enable-libmfx —enable-nvenc —enable-avisynth —enable-bzlib —enable-fontconfig —enable-frei0r —enable-gnutls —enable-iconv —enable-libass —enable-libbluray —enable-libbs2b —enable-libcaca —enable-libfreetype —enable-libgme —enable-libgsm —enable-libilbc —enable-libmodplug —enable-libmp3lame —enable-libopencore-amrnb —enable-libopencore-amrwb —enable-libopenh264 —enable-libopenjpeg —enable-libopus —enable-librtmp —enable-libsnappy —enable-libsoxr —enable-libspeex —enable-libtheora —enable-libtwolame —enable-libvidstab —enable-libvo-amrwbenc —enable-libvorbis —enable-libvpx —enable-libwavpack —enable-libwebp —enable-libx264 —enable-libx265 —enable-libxavs —enable-libxvid —enable-libzimg —enable-lzma —enable-zlib',

    6. Does the VS project need special settings or other codes ?

  • how to make omxh264enc output filler data ?

    8 septembre 2020, par BlueWaterCrystal

    I require filler data from the encoder to artificially raise the bitrate to sustain constant bitrate.

    


    normally x264enc does this but omx264enc doesn't seem to. even though there seems be a value within its code PROP_FILLER_DATA
