Configuration spécifique d’Apache
4 février 2011, parModules 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 ;
Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

Use FFmpeg (or sox) to reduce stereo
24 juin 2019, par JoschuaThe ffmpeg wiki has this method to mix stereo to stereo :
ffmpeg -i input.mp3 -af "pan=stereo|c0code>
How could I do this but reduce the volume of the right part mixed into the left and the left part mixed into the right (diagonal arrows) by 60%, while leaving the volume of both channels as is (downward arrows) ?
(If this could be done with sox, it be great too.)

Implementing hardware accelerated decoding on windows with FFMPEG
24 juillet 2019, par sacha legrandIntel processor incorporates hardware acceleration capabilities for video encoding / decoding.
I use :
Intel 5 series HD graphics & Processeur Intel Core i7-620UE
and/or
Intel Gen9 HD Graphics Engine & Processor Intel Core i7-6600U
So wich hardware acceleration should I use (H264, VC1, H265, etc.) to be more efficient ?
The FFMPEG library provides everything you need to perform decoding.
We accessed these hardware acceleration features by default ?
Should I use a specific API or library ?
I finnally find in
https://trac.ffmpeg.org/wiki/HWAccelIntro
It is Libmfx how seems the best for my case (Windows & Intel)Am I on the right way ?
I should explaine all the possibility so if you have any other doc about that it’s could be cool.
Thank you

Stream and control a playlist to RTMP
20 décembre 2016, par EightI’m currently trying to stream a playlist of files from ffmpeg to an RTMP server.
I’ve managed to get a single file to be streamed correctly, and (I think) a playlist by using :"concat:file1.pm4|file2.mp4|file3.mp4"
I then tried to use the concatenation method from a txt file they explain here :
https://trac.ffmpeg.org/wiki/ConcatenateAnd was able to get it to work. However I seem to have some problems with controlling it. For example, I have no idea if it is possible to tell ffmpeg to skip this file and play the next one in the list, or to pause the stream at all. I already tested editing the txt file while it is streaming, but that didn’t seem to affect what was already streaming at all.
Any idea how I can control my stream from the console ? My end goal would be to make the control into a full web interface later, but I’m not even sure if ffmpeg is my best option to do this.
Any help with ffmpeg or any other options to do this would be greatly appreciated.
