I am working on a project that requires me to detect and track a human in a live video from a webcam connected to a Beagleboard xm. I have completed this task using Opencv in pixel domain. The results on the board are very accurate but extremely slow. Many people have suggested me to leave pixel domain and do the same task in an h.264/MPEG-4 compressed video as it would extremely reduce the computational overhead. I have read many research papers but failed to discover any software platform or a library that I can use to analyze and process h.264 compressed videos. I will be thankful if someone can suggest me some library for h.264 compressed video analysis and guide me further. I know about P and I frames but don't know how to extract them and use which programming software or language to process them.
Thanks and Regards.
