[MPlayer-users] Bug in bitrate calculation?

[Mubashir Cheema]

I tried that and I got:

...
Video stream: 11592.854 kbit/s  (1449106 bps)  size: 22338584 bytes  15.415 secs  444 frames
Audio stream:  384.000 kbit/s  (48000 bps)  size: 709426 bytes  14.780 secs

The bps number does not seem right.  It doesn't relate to the kbps number.
Also I got the bitrate for one program in the stream.  Is it possible to 
get the bitrate for the entire stream?

Thanks.
