Initialisation de MediaSPIP (préconfiguration)
20 février 2010, parLors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.
Dans un premier temps il active ou désactive des options de SPIP qui ne le (...)

FFMPEG conversion from .H264 to MP4 playing too fast
28 juin 2017, par NickRI accidentally deleted a video file but managed to save it with a recovery tool. The video was however corrupted, but I managed to repair that and now have a .h264 file.
The file plays ok in the VLC player. There are a few glitches but on the whole its 98% perfect. However I now need to convert that into a more useable format (mp4 say).
Ive downloaded the FFMPEG tool and have managed to pretty easily copy into mp4 with the following command line instruction :
ffmpeg -i repairedVid.h264 -c copy repairedVid.mp4
The problem is that the video is playing much too fast. I’ve done some research tried some tweaks that seem to have worked for other people (like forcing frame rate and changing the -vsync) :
ffmpeg -i repairedVid.h264 -c copy repairedVid.mp4 -vsync 2 -r 23.976
Ive also tried the crude approach of slowing the video down like this, but this was more of a long shot and I don’t think is the right way to go about it
ffmpeg -i repairedVid.mp4 -filter:v "setpts=1.5*PTS" repairedVid.mp4
This is the output when the video copies to MP4. Looks like it might have a clue to the problem (the video should be much longer than 4:40 minutes) :
frame=13459 fps=1118 q=-1.0 size= 4102773kB time=00:04:40.65 bitrate=119756.4kbiframe=13459 fps=1117 q=-1.0 Lsize= 4102928kB time=00:04:40.65 bitrate=119761.0kbits/s speed=23.3x
video:4102773kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead : 0.003784%I’m totally new to FFMPEG and not having much luck. Any advice would be great.
Thanks in advance

GStreamer x264enc not found
5 avril 2017, par Dominik SchreiberI installed GStreamer-0.10 and all modules (base, good, bad, ugly, ffmpeg) according to these instructions (browse through by clicking prev/next) :
http://www.linuxfromscratch.org/blfs/view/svn/multimedia/gst-plugins-ugly.htmlEverything seemed to have worked just fine but when I want to execute my pipeline I got this error :
glib.GError: no element "x264enc"
Apparently the module was not installed :
gst-inspect x264enc
No such element or plugin 'x264enc'After that I installed the codec by executing :
sudo apt-get install x264
This did not work either. So I installed the latest build manually :
http://www.videolan.org/developers/x264.htmlAfter a successful installation of x264 I ran ./configure on the gstreamer-0.10 ugly modules once again and found out about this :
configure: *** checking feature: x264 plug-in ***
configure: *** for plug-ins: x264 ***
checking for X264... no
configure: No package 'x264' found
configure: *** These plugins will not be built: x264
configure: creating ./config.statusA check if x264 is available seems to get fullfilled :
which x264
/usr/local/bin/x264I’m using ubuntu server 12.04 LTS. Any ideas what I have to do to compile this module properly ? Thanks !
