At use of codec WMV1 for cutting screenshots from a videofile of format .wmv at us a lot of time lasts process of cutting.
As it occurs: I do calculate an interval through which it is necessary to take a screenshot, calculate total of screenshots, and all calls I write in the command file (.sh).
After that, file started work with low priority.
Example of command:
/usr/local/bin/ffmpeg-i /home/.../spool/ap2283-1.wmv-ss 0:0:0-s 240x180-vframes 1-f image2-vcodec mjpeg /home/.../projects/0003-2/1/menu%d.jpg 2>/home/.../projects/0003-2/logs/1.log
25 screenshots are done about 2-3 minutes.. after it, speed decreases! :(
Big thanks for any help!
and sorry for my bad english..
