Hello.
I noticed different speed of application, which was execute with subprocess.Popen() and subprocess.run().
I tested on Linux Ubuntu 17.04 and Windows 10.
My command line is:
"ffmpeg -i big_buck_bunny_480p_surround-fix.avi -f null -"
you can use any video file on your PC.
I used ffmpeg (open source encoder/decoder/and etc.), but you can use any applications, which counts himself speed of work.
I got a difference in speed:
Using by terminal: fps=4402 (frame per second);
Using by run(): fps=4019;
Using by Popen(): fps=3431;
On Windows is difference about 5% percent, on Linux about 10% percent.
I did not use additional flags. All by default.
I downloaded video stream here https://peach.blender.org/download/ |
