EXEC & FFMPEG

Hi all,

I'm using the Tomcat as Web Server. In my JSP file, I write as following

...
String command = "cmd.exe /C ffmpeg -i ....";
Process p = Runtime.getRuntime().exec(command);
p.waitFor();
...


Then it hangs (I have waited for 10 minutes but that process seems never stop). When I look at the converted file, it just about 200KB (actually it must be 800KB). Then I stop the Tomcat, that file is immediately 800KB???

Do you know this problem? Thanks

The usual reason for this sort of failure has to do with consuming the std out and std err output of the Process. See the Javadocs for java.lang.Process.

This problem comes up frequently and is not Tomcat specific - try searching in the Intermediate forum.
