[MPlayer-users] h.264 playback ignoring forced FPS value

Mon Mar 10 07:22:58 CET 2008

With the latest version from SVN (and this has been a problem for over a 
month now with the latest SVN), if I specify an fps value on the 
command-line for playing a file containing h.264 video, the value is 
ignored. In 1.0rc2, this was not the case.

For other types of video formats I've tried, the fps value I provide is 
respected.

Log output is below. Pretty much any file from 
http://www.apple.com/trailers/#section=justhd should exhibit the same 
problem. In practical terms, this is a problem because most HDDVD video 
is incorrectly detected at 29.970 fps, whereas it's really 23.976 fps. 
The only way around this AFAIK is to use the -fps parameter. The result 
when playing HDDVD video encoded with h.264 now, is that every second 
there is a 0.2 second pause in the video output (mplayer plays 24 frames 
in 0.8 seconds, then pauses 0.2 seconds).

Not sure if this is an issue for the ffmpeg list, or this list.
