I encoded a video with SVN-r16573 and these parameters:
ffmpeg -i in.mp2 -acodec copy -i in.avs -b 2500k -maxrate 3500k -bufsize 2500k -aspect 4:3 -f vob out.mpg
It plays fine but there are a few strange things:
* MPC reports the stream bitrate as 3.5Mbit
* GSpot reports a bitrate of 3.5Mbit and a "Sys Bitrate" (whatever it is) of 3920kb/s VBR
* VLC (0.8.x) reports a shorter video duration than what it really is, but plays it fine (the time counter just moves slower).
Is there something wrong with the encoding, or with the players? Is it expected for the maxrate to be reported rather than the average (or actual)?
