how to read H.264 video file format in matlab?

i have made a video using CPP DVR(Video Rcorder). it has given me video in H.264 file format. My question is:

• is there any way of using this h.264 format directly in matlab using VideoReader?
• should i convert it to any other video format (i.e; MP4) before reading in Matlab.? wihout loosing much information.

Please help me in this problem. i have searched alott but couldnt find anything. waiting for positive reply.
