  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

  • How to take a 2.1 file add some data and export as 2.1 file out back ?

    28 novembre 2019, par Teja8484

    I have a source file called A.wav. It has 2.1 channels (Stereo and mono channel) in audacity. I was able to split the stereo into mono channels B and C using the following command. D.wav is the other mono channel.

    ffmpeg -i A.wav -filter_complex "[0:a]channelsplit=channel_layout=stereo[left][right]" -map "[left]" B.wav -map "[right]" C.wav

    After adding some noise to the files i want to export all the three mono files into the same 2.1 format as it was originally present. (B+C = stereo, D=mono) to one 2.1 file. I know this can be done with ffmpeg. But not able to get the right command.

  • How can I convert a webm file with alpha channel to a hevc encoded file that will play in safari on an IPad ?

    21 septembre 2021, par Programming Guy

    I've got a webm file with transparency : https://itype.techforge.com.au/assets/videos/upshot/module1/NP_1A.webm

    


    I'm trying to convert it into something that will play in the video element of a web page in the Safari browser on an IPad.

    


    An example of a file that works is : https://rotato.netlify.app/alpha-demo/movie-hevc.mov

    


    My attempts at doing this conversion have all failed. 3rd party apps seem to all lose the alpha channel.

    


    On my mac I tried ffmpeg

    


    ffmpeg -i input.webm -c:v hevc_videotoolbox -allow_sw 1 -alpha_quality 0.75 -vtag hvc1 output.mov


    


    However, while this resulted in a file that reported a codec of MPEG-H Part2/HEVC (H.265) (hvc1) the resulting file still has a black background instead of a transparent one.

  • FFMPEG batch file to re-encode movies that don't contain string "h265" in file name ?

    11 juillet 2017, par gregm

    I have a batch file that uses FFMPEG to re-encode movies to h265 to reduce file size. I have a few videos that I previously re-encoded over the past couple of years. I want to skip those and at the moment I just manually move them from subfolders before running my script, but this is getting tedious. I’d like to add a command to my batch file that skips those files automatically. All files that have been re-encoded in the past have h265 appended before the file extension. My batch file looks like this, but it isn’t skipping the files with h265 in them :

    for %%a in ("*.*") do findstr /v /c:"h265" "%%a" >nul && \
    
ffmpeg -i "%%a" -c:v libx265 -preset ultrafast \
    
-x265-params [parameters] -c:a copy "%%~na.h265.mp4"
    

    
pause

    What do I need to change to get this to work ?
