[FFmpeg-user] question about calling ffmpeg from java in AIX

[Wang, Liqin, M.S.]

Hi, All,

I have successfully built ffmpeg in AIX 7.1 and am able to generate thumbnail with the following command directly in AIX:

ffmpeg  -ss 8  -i vdata1.dcm  -vcodec bmp -vframes 1 -an -f rawvideo -s 128x128  -y vdata1.bmp

the thumbnail generated just fine.

However, when I call this ffmpeg from Java program using  java runtime:

Runtime rt = Runtime.getRuntime();
       Process proc=null;

  proc = rt.exec(cmd.toString());

...

I got errors of:

frames 1 -an -f rawvideo -s 128x128  -y /qreadscis/mcr/QReadsTest/NonRad/20140731/8_NA_1.2.840.10008.172886328136013394707660428320635002119_1.2.840.10008.148516

Could anyone please let me know why it behaves in such a way?

Calling from Java is working fine in window.

Thanks
