Record Screen using ffmpeg doesn't work in tomcat server(Could not find codec parameters for stream 0)
4 septembre 2019, par Norhan MohamedI have the following problem,when I executed the below FFMPEG terminal command in command it prompt successfully.
C:\\ffmpeg\\bin\\ffmpeg.exe -f gdigrab -i desktop -c:v libx264 -analyzeduration 15M -probesize 15M -pix_fmt yuv420p -loglevel 99 C:\\ffmpeg\\bin\\video.mp4but I have a problem while running a command from a java web application.I used
runtime.exec(). It’s working fine at Netbeans. But not working at all after deploying on tomcat server.
Here is my code :String command = "C:\\ffmpeg\\bin\\"
+ "ffmpeg.exe -f gdigrab -i desktop -c:v libx264 -analyzeduration 15M -probesize 15M -pix_fmt yuv420p -loglevel 99 C:\\ffmpeg\\bin\\video.mp4";
System.out.println("command = " + command);
try {
Process p = Runtime.getRuntime().exec(command);
final InputStreamReader isr
= new InputStreamReader(p.getErrorStream());
Thread th = new Thread() {
public void run() {
try {
BufferedReader br = new BufferedReader(isr);
String line = null;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
} catch (Exception ex) {
}
}
};
th.start();
} catch (IOException ex) {
System.out.println("Error 1 : " + ex.getMessage());
} catch (Exception ex) {
System.out.println("Error 2 : " + ex.getMessage());
}And here is log for error

Rotate 360 video with ffmpeg
9 septembre 2019, par Leos LiterakI have 360° video and I want to fine tune its orientation with ffmpeg. I need to rotate it by 90° clockwise horizontally (turn it left). I found some helpful resources stating that the
rotatefilter would do the trick. So I tried :ffmpeg -i Petr_doskok.mp4 -vf "scale=2048x1024,rotate=-PI/2" -r 30 -c:v libx265 -b:v 15M -pix_fmt yuv420p -c:a aac -b:a 192K Petr_doskok_rotated.mp4
