La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...) -
Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.

FFmpeg skipping time after concat
19 septembre 2017, par Manul HüttingerI am trying to concatenate videos and in my resulting Videos I have the issue that at the concat edges my video is skipping/glitching.
General Workflow
in general my workflow looks like this
- Stream via ffmpeg
- capture stream and segment all 2 mins in to TS files
- concat TS file to MP4 video
- cut MP4 video at the desired Timestamps
Detailed Look at Step 4
as I am handling 2-hours+ videos I don’t want to re-encode the whole video. So I am looking for the closest I Frames to my In and Outpoint and cut 1 Frame before/after. As my result I get 3 Videos (front/middle/back). Now it is only needed to re-encode front and back and concat all three Videos.
So far the theoryGeneral Observations
As I look at my resulting video, I obeservated the following.
frontpart duration is e.g. 3.2 secs. I skip framewise through the Video and get nice and clean timestamps ( 00:00:02.620, 00:00:02:660 )
As soon as I get to my cutting edge the timestamps are skipping some frames and changing (00:00:03.200, 00:00:03.408 ,00:00:03.409). When I look only at the single frame images, their are no missing/dropped frameswhen I concat my TS files, the results contains a messed up frame rate e.g from constant 25 F/s to 25.0096 F/s

Using ffmpeg for streaming video composition from Python : why the sound is cut only when streaming into a mp4 file ?
4 décembre 2017, par redantlabsI am using ffmpeg within Python for automatizing some video compositions. To do so, I am using the subprocess module of Python and run a ffmpeg command with a pipe input. This allows me to stream frame by frame the video composition from my array of raw images (numpy matrices) into ffmpeg. In the following example, I reduced the video composition to a simple video of a duration of 12 seconds. The produced ffmpeg command is :
ffmpeg -i stream_audio.mp3 -re -f rawvideo -vcodec rawvideo -s 1280x720 -pix_fmt rgb24 -r 25 -i - -map 0:a -map 1:v -y -strict -2 -f mp4 -pix_fmt yuv420p out.mp4The file stream_audio.mp3 is a well formed mp3 file corresponding to the audio output of the output mp4 file. However, the sound in the output file out.mp4 is cut 3 seconds before the end.
If I am trying to output any other format (for example avi), I do not observe this problem. The following command produces a well formed avi file.
ffmpeg -i ./stream_audio.mp3 -re -f rawvideo -vcodec rawvideo -s 1280x720 -pix_fmt rgb24 -r 25 -i - -map 0:a -map 1:v -y -b 4096k -f avi -pix_fmt yuv420p out.aviI tried to reproduce the bug with the most simple ffmpeg command without passing by Python, but did not succeed.The closest I have done is the following :

Hyper fast Audio and Video encoderThe file samplevideo.mp4 can be found here : sample videos, the stream_audio.mp3 file is a simple extraction of the audio track of the samplevideo.mp4 file :
ffmpeg -i samplevideo.mp4 stream_audio.mp3Thanks for your help.
p.s : Here are the different logs of the ffmpeg commands :

ffmpeg pipe webcam stream input to two outputs image and video with audio included
23 septembre 2017, par Arianna Gomez VargasI have the next command :
sudo ffmpeg -ar 44100 -ac 2 -f alsa -i hw:1,0 -f v4l2 -codec:v h264 -codec:a aac -ab 128k -framerate 30 -video_size hd720 -itsoffset 0.5 -i /dev/video0 -vf fps=1 snapsh%d.png -f mpeg -b:v 5000k -copyinkf -codec:v copy -codec:a aac -ab 128k -g 10 - | sudo ffmpeg -y -i - out.mp4and the objetive it is record audio and video simultaneously, and pipe the output to be capable to take screnshots of the output video. I’m using a logitech webcam, raspberry pi 3, the last version of ffmpeg with h264 and alsa support.
But it is not working for me :(, I think that the problem it is enconding the audio stream, but I can find a solution yet.
Someone have any suggest ? ThanksThis is the output
