MediaSPIP 0.1 Beta version
25 avril 2011, parMediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
The zip file provided here only contains the sources of MediaSPIP in its standalone version.
To get a working installation, you must manually install all-software dependencies on the server.
If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...) -
Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

Encoiding Video Frame Error with VAAPI encoding [on hold]
26 octobre 2018, par Tcor5I’m attempting to convert one of the FFMPEG Muxing examples (https://ffmpeg.org/doxygen/2.8/muxing_8c.html) to use VAAPI hardware encoding, using https://www.ffmpeg.org/doxygen/trunk/vaapi_transcode_8c-example.html as an example.
The problem is when I call avcodec_open2, it returns :
Error encoding video frame : Input/output errorI believe I have set up all the HW contexts and frames appropriately but it seems the encoding is failing due to an invalid VASurface ID.
Does anyone have any tips on how to resolve/troubleshoot this ?Thanks

ffmpeg rotate and resize
23 août 2014, par user1321964I’m trying to resize a movie and to rotate it counter-clockwise using ffmpeg.
I can achieve one or the other ok individuallyffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV
OR
ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV
but if I try to do both, either-
ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV
ffmpeg -i resize.MOV -vf "transpose=2" toutp.MOV
OR
ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV
ffmpeg -i rotate.MOV -s 406x720 toutp.MOV
the final movie does not play, only audio, no video ; neither previewing in Finder, nor in Quicktime. More seriously once I have attempted to play it, I can’t then play any other movie whatsoever (only audio) - quicktime won’t quit, constantly need to force-quit it. The only way to then restore seems to be reboot OS-X
This though does work -
ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV
ffmpeg -i rotate.MOV -s 720x406 toutp.MOV
but doesn’t do what I want - it stretches the movie in the wrong direction
Any ideas ?
