[MEncoder-users] How to write out frame size sequence of encoded video?

[CEM MENGI]

Hi all,

due to research purposes, i want to record the frame size sequence (i.e.
amount of data per frame in bytes) of an encoded video (mpeg, h.263,...).
The video could be streamed from a streaming server, from a file on hard
disk or from a cd or dvd.
Is there a possibility to write out the frame size sequence with mplayer?

Thanks,

Cem
