[vlc-devel] libvlc-1.0.0 dated 2009-jul-07 crashes in swscalar

[J Decker]

after renaming all of the following

libswscale_plugin.dll.asdf
libi420_rgb_sse2_plugin.dll.asdf
libi420_rgb_mmx_plugin.dll.asdf
libi420_rgb_plugin.dll.asdf

the program no longer threw a null reference exception... but I had no
video, I did have sound.


each one

i420 sse2 (refernenecd a NULL in esi)

   mov dword ptr [esi],eax;  eax = 0x00101010, esi=0x00000000


then mmx (same)
then just the _plugin (same)
