Just did a fresh download and build and same problem. Now N-59141-g48d39c8 (mingw32)

Everything builds and links as expected.

Some build flags I use:


The first av_log message I get for any file is:

"Value 2147483648.000000 for parameter 'blocksize' out of range [1 - 2.14748e+009]"

I don't get this message in previously working build and get something normal.

I will see if I can come up with some more details on it.
