[vlc-devel] Win32 crash with vlc and ffmpeg svn from today

[Bjørn Olav Ruud]

VLC svn rev. 20477 compiles fine with ffmpeg rev. 9255 on Cygwin, but
crashes when transcoding a MPEG-2 TS file to MPEG-4 TS. Playback is
fine. If I convert using ffmpeg.exe from the same compile it works.
This is the gdb output:

Program received signal SIGSEGV, Segmentation fault.
[Switching to thread 3320.0xc80]
0x0288caee in ff_fdct_sse2 (block=0xde83d0) at i386/fdct_mmx.c:369
369     FDCT_COL(sse2, xmm, movdqa)


If this is a SSE problem, can I disable support for SSE instructions?
I couldn't find a configure option for it, only MMX.
