[MEncoder-users] 24000/1001 not recognised as valid framerate for MPEG-2

[John Brown]

I am using MEncoder dev-SVN-r25958-3.4.5 on Windows XP.

According to mplayer -identify, ID_VIDEO_FPS=23.976

Minimal command line:
$ ./mencoder.exe -nosound -ovc lavc -lavcopts vcodec=mpeg2video -of mpeg
mpegopts tele_src=24000/1001:tele_dest=30000/1001 -o $TMP/test.mpg test.avi

Result:
videocodec: libavcodec (640x480 fourcc=3267706d [mpg2])
[mpeg2video @ 00BCF300]MPEG1/2 does not support 31001/1293 fps
Could not open codec.
FATAL: Cannot initialize video driver.

Inserting -fps 24000/1001 does not help. I have to insert
-fps 24 and change tele_src to 24.

MEncoder dev-SVN-r24764-4.2.1-sjlj (executable date-time 
= 2007-10-17) does not have this problem.
