[Ffmpeg-devel] Gray Scale decoding of MPEG4 data and debugginglibavcodec
Mon May 15 23:17:19 CEST 2006
Yes really crash. Turns out it's not just the gray scale decoder mpeg4
decoding in general is crashing. Seems to have something to do with my
latest pull down of FFMPEG, I tested by old sandbox and it's seems to work
So I pulled down the latest FFMPEG stuff today and rebuilt and now I can't
find the .lib files for linking with the shared libraries. Did you change
the way things are built for the shared windows libraries?
I understand you don't support MSVC how about another debugger that does
work on a windows system?

Do you mean it really crashes, or just returns an error? In case of a
proper crash, please send a complete bug report as per the
instructions on the web page.

We don't support msvc. Sorry.
