Keeping control of your media in your hands
13 avril 2011, parThe vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.

Taille des images et des logos définissables
9 février 2011, parDans beaucoup d’endroits du site, logos et images sont redimensionnées pour correspondre aux emplacements définis par les thèmes. L’ensemble des ces tailles pouvant changer d’un thème à un autre peuvent être définies directement dans le thème et éviter ainsi à l’utilisateur de devoir les configurer manuellement après avoir changé l’apparence de son site.

Streaming Webcam using VLC +FFmpeg over lan - Error : cannot pre fill buffer
23 juin 2016, par user1804015I’ve been trying to stream my webcam over lan using VLC and FFmpeg
but I end up with the error "Main stream error : cannot pre fill buffer"
Here is the code I’ve tried
ffmpeg -f x11grab -s 1680x1050 -r 30 -i :0.0+0,0 -vf "movie=/dev/video0:f=video4linux2, scale=180:-1, setpts=PTS-STARTPTS [movie]; [in] setpts=PTS-STARTPTS, [movie] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" -f alsa -ac 2 -i pulse -vcodec libx264 -preset ultrafast -s 1280x768 -acodec libfaac -threads 0 -f mpegts - | vlc -I dummy - --sout '#std{access=http,mux=ts,dst=thalha:3030}'

}my final video crop and rotate but green frames and colored frames mixed with this.
How to fix this problem. I’m not aware of iplimage. In some blogs they mention its YUV format. first u need to convert Y and then convert UV.
How to solve this problem ?

How to set crontab in order to run multiple python and a shell scripts ?
5 janvier 2021, par Alexander MitsouI need to start three python3 scripts and a shell script using crontab. These scripts should run at the same time without any delay. Each script runs exactly for one minute. For instance I have scheduled crontab to run these scripts every 5 minutes.


My problem is that, if I attempt to run each script individually from terminal it executes with no further errors, but using crontab nothing happens.


DISCLAIMER : If I set up the Python3 scripts individually in crontab, they work fine !


Here's my crontab set up :


*/5 * * * * cd /home/user/Desktop/ && /usr/bin/python3 script1.py >> report1.log

*/5 * * * * cd /home/user/Desktop/ && /usr/bin/python3 script2.py >> report2.log

*/5 * * * * cd /home/user/Desktop/ && /usr/bin/python3 script3.py >> report3.log

*/5 * * * * cd /home/user/Desktop/ && /usr/bin/sh script4.sh >> report4.log 



In addition I need to mention that the shell script contains this command (FFMPEG) :


#!/bin/bash

parent_dir=`dirname \`pwd\`` 
folder_name="/Data/Webcam" 
new_path=$parent_dir$folder_name 


if [ -d "$new_path" ]; then
 echo "video_audio folder exists..."
else
 echo "Creating video_audio folder in the current directory..."
 mkdir -p -- "$new_path"
 sudo chmod 777 "$new_path"
 echo "Folder created"
 echo
fi

now=$(date +%F) 
now="$( echo -e "$now" | tr '-' '_' )"
sub_dir=$new_path'/'$now 

if [ -d "$sub_dir" ]; then
 echo "Date Sub-directory exists..."
 echo
else
 echo "Error: ${sub_dir} not found..."
 echo "Creating date sub-directory..."
 mkdir -p -- "$sub_dir"
 sudo chmod 777 "$sub_dir"
 echo "Date sub-directory created..."
 echo
fi

fname=$(date +%H_%M_%S)".avi"
video_dir=$sub_dir'/'$fname
ffmpeg -f pulse -ac 1 -i default -f v4l2 -i /dev/video0 -vcodec libx264 -t 00:01:00 $video_dir 



The log file of that script contain the following :


video_audio folder exists...
