C# on linux : FFmpeg (FFMediaToolkit) MediaOutput..Video.AddFrame(FrameToImageData(ImageData)) causes program to exit with code 139
19 mai 2021, par Jan ČernýIn my C# program I have instance of
MediaOutputfrom FFMediaToolkit. It is initialized like this :

MediaOutput buffer = MediaBuilder.CreateContainer(videoPath).WithVideo(new VideoEncoderSettings(width: width,
 height: height, framerate: frameRate,
 codec: VideoCodec.H264)
 ).Create();


When I want to add frame to buffer I use this code :


private static ImageData FrameToImageData(Bitmap bitmap) {
 Rectangle rect = new Rectangle(System.Drawing.Point.Empty, bitmap.Size);
 BitmapData bitLock = bitmap.LockBits(rect, ImageLockMode.ReadOnly, PixelFormat.Format24bppRgb);
 ImageData bitmapImageData = ImageData.FromPointer(bitLock.Scan0, ImagePixelFormat.Bgr24, bitmap.Size);
 bitmap.UnlockBits(bitLock);
 return bitmapImageData;
}

public void AddFrame(Bitmap frame) {
 buffer.Video.AddFrame(FrameToImageData(frame));
}


But when code reaches
buffer.Video.AddFrame();it exits with code139without throwing any exception.

I have two test files and only one is causing it. One is
.pngfile 100x100 and it works fine. The other is.pngfile 1000x1000 and it makes program exit as soon as it reaches this method.

What exit code 139 means in C# ?

How can I diagnose this problem when it is not throwing any exceptions ?

How can I fix it ?

Thank you for help. If you need any more information, leave a comment and I will add it soon as possible.

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...
