  • Changer son thème graphique

    22 février 2011, par

    Le thème graphique ne touche pas à la disposition à proprement dite des éléments dans la page. Il ne fait que modifier l’apparence des éléments.

  • 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.

  • Set ffmpeg presets dir in macosx

    30 août 2012, par alexserver

    I installed a binary build of ffmpeg in macosx by following instructions on this post : http://hints.macworld.com/article.php?story=20061220082125312

    It says you only have to download ffmpegX which already has a compiled ffmpeg, and copy to /usr/local/bin to have ffmpeg available for command line.

    well, it runs fine, i don't have ffmpegX but i have Miro Video Converter http://www.mirovideoconverter.com/ which i suppose is the same since this is a Gui solution with a compiled version of ffmpeg, so it works like a charm.

    Now i want co be able to use ffmpeg presets, this Miro Video Converter also have a folder called ffmpeg_presets which i'd like to copy in a public dir and tell ffmpeg to use it. do you know how to do this ?

  • Remux to MKV but add all streams using FFmpeg

    7 avril 2017, par sashoalm

    I’m trying to automate FFmpeg to remux all video files in a given directory to MKV. I’m currently using

    ffmpeg -i $INPUT -c copy $OUTPUT.mkv

    However, some streams are skipped that way - for example, if there are 2 audio streams only 1 goes to the output file.

    How do I specify that all streams from the input must be copied to the output ?

    Since I’m trying to automate FFmpeg, it would be best if the command does not change for each file, i.e. manually specifying all the streams with -map would require me to first parse every file. I would do this if I need to, but if there is a better solution I’d prefer that.

  • FFmpeg AVI to MP4 preserves sound, but not images [migrated]

    21 février 2013, par user1711384

    Working with FFmpeg at a conversion (any file to MP4 (H.264/AAC)) :

    ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 1 -an -f mp4 -movflags faststart /dev/null
    
ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 2 -c:a libfdk_aac -b:a 128k -movflags faststart xxx.mp4 2>&1

    With MPEG and WMV file it's working. With two different AVIs it didn't work. Logfiles from path 1 aren't generated and output 1 is empty, output 2 of course generates an error.

    After removing -profile:v baseline in both commands, the video file is successfully generated, but it's not possible to play it in JW Player (sound yes, but no image).

    This is the result of the first command :
