  • 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 (...)

  • How to exclude night images to be passed for ffmpeg ?

    4 novembre 2019, par LA_

    My files have the following filenames -

    YYYYMMDDHHmmSS.jpg

    I pass them to ffmpeg (on MacOS) for timelapse creation :

    ffmpeg -framerate 500 -pattern_type glob -i '*.jpg' -c:v libx264 -pix_fmt yuv420p out.mp4

    Now I would like to exclude night photos, for ex., if filename is between YYYYMMDD200000.jpg and YYYYMMDD080000.jpg, then files shouldn’t be passed to ffmpeg.

    How could I achieve that (ideally - without moving files) ?

    Upd. Using the following command now, but it captures the following hours only : 10-19.

    ffmpeg -framerate 500 -pattern_type glob -i '2019[01][089][012][0123456789]1*.jpg' -c:v libx264 -pix_fmt yuv420p out3.mp4

  • 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 ?

    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 ?
