[FFmpeg-devel] [PATCH] avformat/utils: disabled debug code to collect format probing statistics

[Stefano Sabatini]

> This allows collecting statistics on probing scores and the amount of data
> probing needed for various files and formats.
> For example it can be used to find out which formats tend to need more
> data for probing or which files are probed with less certain/lower scores

nitt: *f = ...

probably more readable/parsable:
fprintf(f, "probe_size:%d format:%s score:%d filename:%s\n", probe_size, (*fmt)->name, score, filename);

LGTM if useful.
