[MPlayer-users] bit stream buffer management in MPlayer

[boku]

Dear all,
    I'd like to ask about the bit stream buffer management.
I've checked the code and found there's
a #define VIDEOBUFFER_SIZE which is 0x100000 (1MB).
What does MPlayer do if the video bit stream >1MB?
What does libmpdemux work to parse the bit sequence since the decode is
frame based?
Does it always move the pointer of the "start" to the first beginning
character of the frame which is to be decoded?
Thanks a lot!

BR,
boku
