I think the best solution is to just change the parameter type of
"number", currently int, to uint64_t. The function av_get_frame_filename2
is called in many places with an int "number" argument, except for via the
frame_pts codepath, where it's a uint64_t "number" argument. It seems
safer to me to cast int into uint64_t rather than the other way round, and
I don't foresee any side-effects, though I'm inexperienced with C. Shall I
try to submit that as a patch?
