New submission from Vitor <[email protected]>:
Might be just a compiler bug, but this sounds unlikely since
all fate tests pass fine in my box. File on
samples/fate-suite/wmv8/wmv8_x8intra.wmv .
Using "./configure --cpu=host --disable-asm"
vi...@vitor:~$ ffmpeg -flags
+bitexact -i ../fate-suite/wmv8/wmv8_x8intra.wmv -an -f md5 -
MD5=d83475cf94dc5113b7568876a6f7e31b
While
using "./configure --cpu=host --disable-asm --disable-optimizations"
