[MPlayer-users] Mencoder segfaults at end of MPEG2 stream

I'm trying to encode a raw MPEG2 stream ripped from DVD. The stream seems
to be not correct finalized: At the end of the encoding process, mencoder
prints a message "get_buffer() failed (<four values here>)" and segfaults.

After having a look at the libavcodec library I found that the message
is generated in libavcodec/mpegvideo.c function alloc_picture(). The
function returns a value -1 after showing the message. But the error is
not passed to the calling functions.

Unfortunately, the segfault causes the divx2pass.log file to be scrambled.
Even if I let terminate mencoder immediately after showing the error message
by adding an exit(-1) behind the printf() line, the divx2pass.log file
is scrambled and therefore unusable for the second encoding pass.

Any ideas?
