2013-03-11 16:10:31 -0600 | asked a question | Slow Processing on Rasberry Pi I'm building an application that takes two video sources, pulls their frames, and places them one after another in a third video, essentially "interweaving" the frames. I had planned on using the Raspberry Pi for this, but the processing speed is unreasonable; it takes five minutes to produce 5 seconds of video. Is there something I could do to (significantly) speed up the processing time of the application, beyond switching hardware? Here's the basics of the code: I've tried a few different codecs, with no noticeable difference. I've also run this on a Core 2 Duo running Ubuntu 12.10 with a processing time of approximately 20 seconds; I realize the Raspberry Pi is a single core processor, but I'm hoping to increase performance to under a minute, regardless. Written in C++, running on the Raspberry Pi (model B, processor overclocked to 1GHz), using OpenCV 2.4.9. |
