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.

How to comvert MOV to MP4 with metadata [closed]
11 janvier 2020, par Nadav RosenbergI’m trying to convert mov videos from iphone to mp4 videos but I want to save the metadata.
I had tried some options but ffmpeg for android seems the best.Does any one have some kind of a template that I can just implement it ?
I don’t have a clue how to write in ffmpeg ..[screenshot from the app][1]
[another screenshot from the app][2]
log (the input is different then in the screenshot) :
ffmpeg -y -i "/storage/9C33-6BBD/DCIM/×¢×™× ×‘/IMG_5267.MOV" -c:v libx265 -q:v 5 -c:a aac -ab 128k -ar 44100 "/storage/emulated/0/FFMPEG/IMG_5267.mp4"

Metal Gear Solid VP3 Easter Egg
4 août 2011, par Multimedia Mike — Game HackingMetal Gear Solid : The Twin Snakes for the Nintendo GameCube is very heavy on the cutscenes. Most of them are animated in real-time but there are a bunch of clips — normally of a more photo-realistic nature — that the developers needed to compress using a conventional video codec. What did they decide to use for this task ? On2 VP3 (forerunner of Theora) in a custom transport format. This is only the second game I have seen in the wild that uses pure On2 VP3 (first was a horse game). Reimar and I sorted out most of the details sometime ago. I sat down today and wrote a FFmpeg / Libav demuxer for the format, mostly to prove to myself that I still could.
Things went pretty smoothly. We suspected that there was an integer field that indicated the frame rate, but 18 fps is a bit strange. I kept fixating on a header field that read
0x41F00000. Where have I seen that number before ? Oh, of course — it’s the number 30.0 expressed as an IEEE 32-bit float. The 4XM format pulled the same trick.Hexadecimal Easter Egg
I know I finished the game years ago but I really can’t recall any of the clips present in the samples directory. The file mgs1-60.vp3 contains a computer screen granting the player access and illustrates this with a hexdump. It looks something like this :
Funny, there are only 22 bytes on a line when there should be 32 according to the offsets. But, leave it to me to try to figure out what the file type is, regardless. I squinted and copied the first 22 bytes into a file :
1F 8B 08 00 85 E2 17 38 00 03 EC 3A 0D 78 54 D5 38 00 03 EC 3A 0D
And the answer to the big question :
$ file mgsfile mgsfile : gzip compressed data, from Unix, last modified : Wed Oct 27 22:43:33 1999
A gzip’d file from 1999. I don’t know why I find this stuff so interesting, but I do. I guess it’s no more and less strange than writing playback systems like this.
