Hi

Here is the command I am using:
./mencoder  -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames
-of lavf -ffourcc FLV1 -ovc lavc  -oac mp3lame -srate 22050 -lameopts
preset=64:mode=3  ~/videos/testvid.mov -o ~/videos/testvid.flv  -lavcopts
vcodec=flv:vbitrate=256:v4mv:mbd=2:trell:mbcmp=3

I debugged it a bit more, its crashing in ff_fdct_sse2() method.

disabling sse2 in configure (had to hack configure script to do so), but it
still uses the method.

'config.h' and 'config.mak' contain your configuration options.
Note: If you alter theses files (for instance CFLAGS) MPlayer may no longer
      compile *** DO NOT REPORT BUGS if you tweak these files ***

'make' will now compile MPlayer and 'make install' will install it.
Note: On non-Linux systems you might need to use 'gmake' instead of 'make'.

Please check mtrr settings at /proc/mtrr (see DOCS/HTML/en/video.html#mtrr)


Check configure.log if you wonder why an autodetection failed (check whether
the development headers/packages are installed).
Do not report compilation errors if you used any of the --enable-* options
(except --enable-gui and maybe --enable-debug).

If you suspect a bug, please read DOCS/HTML/en/bugreports.html.


Thanks,
Dwipal
