To ensure I was encoding properly, I made a raw h264 file and made sure I could stream out the file with mediaserver.exe, which with VLC it acted like the frame time was off(played quickly), but using SMPlayer everything worked fine(so I think that particular issue is VLC and not with the encoding).<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>My second test is to see if I can get Live555 to now stream the output, meaning, instead of writing to a file, send out through RTSP.
