[MPlayer-dev-eng] [PATCH] MPEG-2 TS 60000/1001 FPS Conversion Error in mencoder

[Bill Adams]

I have been having some problems converting a 720p MPEG-2 TS stream.  
You can see the thread (along with a link to a sample stream) here:
http://lists.mplayerhq.hu/pipermail/mencoder-users/2006-June/003345.html

The grand summary is that when I run mencoder (svn from Nov 25, 2006) on 
60000/1001 FPS 720p MPEG-2 TS, I get the following bit of output:

mencoder \
        -oac copy \
        -ovc lavc \
        -lavcopts 
vcodec=mpeg2video:vqscale=4:dia=4:mbd=2:trell=yes:mv0=yes:cbp=yes:keyint=50 
\
        -mpegopts muxrate=36000 \
        -of mpeg \
        -o Test.mpg Bad-FPS.ts
[snip]
[mpeg2video @ 0x861accc]MPEG1/2 does not support 19001/317 fps

After digging around for a while, I came across the bug. In mencoder.c 
the line:

 AVRational q= 
av_d2q(force_ofps?force_ofps:sh_video->fps*playback_speed, 30000);

caps the numerator to 30,000 (I think). Changing this to:

 AVRational q= 
av_d2q(force_ofps?force_ofps:sh_video->fps*playback_speed, 60000);

fixes the problem.
