[MEncoder-users] Problems with mencoder on Win32 and MKV

[Berend Dekens]

Hi,

I'm using Transcode360 for my Xbox360 to view video on my TV. Some stuff 
is encoded in Matroska (most of which is x264) and I can't get this 
content to work. It either runs heavely out of sync (seconds out of sync 
after seconds of video) and it looks like the video is playing too fast. 
With some files it runs fine for a while and then cuts out with messages 
about having too many packets in the audio buffer.

An example of how the mencoder is executed under windows MCE:
mencoder.exe -quiet -delay 0 -oac lavc -srate 48000 -af 
lavcresample=48000 -of mpeg -mpegopts format=dvd -o "C:\Program 
Files\Transcode360\Buffer\Pumpkin Scissors - 03 (1024x576 h264).360" 
-ovc lavc -vf scale=720:404,expand=784:432,harddup -lavcopts 
vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=8000:keyint=15:aspect=16/9:acodec=mp2:abitrate=320 
-ofps 24000/1001 -slang eng -subpos 92 -alang jp -alang jpn "Pumpkin 
Scissors - 03 (1024x576 h264).mkv"

I tried playing with the options and I can't get it to work. I replaced 
the stock mencoder.exe with numerous newer builds, some of which seemed 
to improve the situation a little, other only made it worse.
What is going wrong? The strange thing is that everyone seems to use MKV 
without problems... So why do I run into a brick wall time after time 
(this has been broken for over a year now).
