[MPlayer-users] Warnings and errors during RMVB -> MPEG2 DVD conversion changing over time

[John Brown]

I have 3 CVS versions of mencoder.exe; 060124-18:40, 060311-00:26 and 
060322-17:47.
When I convert an RMVB to DVD-compliant MPEG2, I get the following results. 
I am showing everything that happens between 2.0s and 3.0s in each case, but 
I get simlilar warnings or errors throughout
the file. My command line is:

mencoder.exe bleach69b.rm -of mpeg -mpegopts format=dvd -vf 
scale=304:208,expand=352:240,harddup -oac lavc -ovc lavc -lavcopts vcodec=
mpeg2video:vbitrate=720:vrc_maxrate=2000:aspect=4/3:acodec=ac3:abitrate=96:vrc_buf_size=
1835:keyint=18      -ofps 30000/1001 -srate 48000 -af lavcresample=48000
-aspect 4:3 -o test.mpg  > log.txt 2>&1

I built mencoder using gcc-3.4.2 (mingw) on Windows XP SP2.

I believe that the resulting MPEG plays OK in all cases, but I have not 
tested whether dvdauthor can handle them.

To summarize: in descending date order, CVS1 = OK, CVS2 = Errors, CVS3 = 
Warnings. Is CVS3 (warnings) an improvement on CVS1 (no warnings)? I have 
not filed a proper bug report with sample files and all the rest, since I 
don't know if it is a bug. I can if you want, though.
