Mjpg-streamer is a good open source project to use as a video server, using the V4l2 interface. We talked about the transplant process earlier, but in certain circumstances the project does not meet our needs, so we need to modify the source code, or directly write a video server. Before you modify the source code or write your own server, we

Most of the cameras are now using a free-drive camera, there are generally two transmission formats, YUY2 and Mjpg, the former is uncompressed image format video, system resource consumption (because no decoding), do not need a decoder, the disadvantage is that the frame rate is slightly slower (limited by the bandwidth of USB allocation), The latter is equivalent to the JPEG image Compression format, the advantage is high frame rate (video open fast,

I 've seen in our threads that FFmpeg is already embedded and used inside opencv, is this right? Maybe I need to recompile opencv with ffgmpeg support? In this case how I can do this under windows? Thanks-grifo APR 3'09
I'm not aware of this. however, FFmpeg is an application where as ffmpeglib is a library. if you are new to these please look at the dranger.com tutorials. -indeera Apr 3 '09
