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 synchronize audio and video streaming for not fixed FPS streaming ?
16 octobre 2019, par PadfootIt’s a 3-stage process.
- In the first stage, a video (with audio) is recorded at a fixed 25 FPS rate.
- In the second stage, it’s demuxed in two different channels and the video is processed.
- In the third stage, the audio and video are again synchronized and muxed together.
The issue is for the third stage, the video after the processing, is having varying FPS rate (like 16, 18, 30, 35 FPS). Is there any way to synchronize the audio with the video at original FPS rate. I’m trying to use FFMPEG for this but no success.

avformat/movenccenc : Fix memory leak for muxing CENC-encrypted files
31 janvier 2021, par Vadym Bezdushnyiavformat/movenccenc : Fix memory leak for muxing CENC-encrypted files
Memory for auxillary_info was not freed after usage.
Leak can be reproduced with following commands :
Optionally, generate input video :
ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 input.mp4Run ffmpeg with valgrind :
valgrind —leak-check=full —show-leak-kinds=all \
ffmpeg -y -i input.mp4 -vcodec copy -acodec copy \encryption_scheme cenc-aes-ctr \
encryption_key 00000000000000000000000000000000 \
encryption_kid 00000000000000000000000000000000 \
ffmpeg_encrypted.mp4For test video which has duration of 10 sec, leak is 4 Kb.
For 100 sec video, leak will be 33 Kb. Most likely,
leaked memory will grow linearly to the number of input frames.Signed-off-by : Vadym Bezdushnyi <vadim.bezdush@gmail.com>
