yes

Combine that with myself often lazyly throwing av_log(0,0, ...) in as a quick
debug fprintf(stderr, ...
and the 0 log level then triggers the valgrind backtrace
For me its 99% of the time not what i want.

I wonder if other people use that backtrace feature ?
or if it would be better switched off by default, or
switched off for log_level == 0

or maybe i should just stop using av_log(0,0, ...

thx
