How to get bitrate for VBR MPEG-video files?

CBR MPEG has an entry for average bitrate, but for VBR it's set to 0x03FFFF. Do I assume that means I have to treat it like headerless VBR MP3 and just scan the whole file frame-by-frame to figure out the bitrate at all points in the file and calculate my own average? If so, how do I know how long an MPEG data frame is?

Do you need to know the bitrates at the encoder side or at the decoder?
