Support audio et vidéo HTML5
10 avril 2011MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...) -

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...
Date Sub-directory exists...

Convert MPEG4 to MPEGTS on Android with FFmpeg
3 juin 2013, par ArdoramorOk, so obviously I know very little to none about ffmpeg API when I made the original post... it is quite overwhelming when one starts learning about digital media and conversion details. After reading quite a bit more and going through ffmpeg source, I was able to get a working output from mp4 to mpegts. The concept is similar to executing :
ffmpeg -i in.mp4 -vcodec copy -acodec copy -vbsf h264_mp4toannexb out.tsBut as I mentioned before, I need to implement it with ffmpeg API in C.
So, although I am able to generate a playable .ts file, its video and audio streams are not synced. That is, playing them back on Android tablet plays the video very slowly while audio is playing at normal speed and then (once audio stream ends) video plays at normal speed to the end. Playing the same generated .ts file in VLC produces a very condensed audio (as though fast-forwarded) and plays video fine.
There are still many aspects of media conversion that I am not familiar with. I am sure that some of them prevent me from successful conversion.
Here is some information (via ffprobe) about the files :
in.mp4 - file generated via Android recording - MPEG4 (H.264 + AAC)
ffmpeg.ts - file generated via ffmpeg conversion - MPEG2TS (H.264 + AAC)

[/PACKET]As you can see, ffmpeg.ts starts out with video packets that do not have pts/dts. The audio packets that follow contain pts/dts. This repeats until the end. All video packets do not have pts/dts according to ffprobe output.
However, out.ts starts with audio packets and alternate with video packets. Here, video packets also do not have pts/dts. The difference is that here there is one video packet between a series of audio packets. What happened to the rest of the video packets (ffmpeg.ts has 5 audio followed by 5 video).
Obviously, I'm still learning and don't know way too much yet... Does anything jump out as obvious a problem to anyone ? I will greatly appreciate any info / suggestions but will continue to grind at it !!
