[FFmpeg-devel] Regression tests fail on MinGW

[Ramiro Polla]

Hello,

Regression tests fail on MinGW since r11142. I've been procrastinating 
to find the cause for an incredible amount of time.

The problem is that strtod() on Windows doesn't like hex strings. When 
av_get_string() was used instead of av_get_double(), it would pass hex 
strings to av_set_string() (which uses av_strtod(), which uses strtod()) 
for FF_OPT_TYPE_FLAGS. So -flags +bitexact wasn't doing anything, and 
hence the tests fail.

This should be fixed on MinGW, and I sent a message about it on [0].

I haven't checked, but I assume this doesn't affect Cygwin, because it 
reimplements almost everything to be compliant.

By the way, am I the only one running make test on MinGW and actually 
caring about the result? Doesn't anyone else that distributes builds do 
this?
