Comment (by Filip):

 [https://github.com/FFmpeg/FFmpeg/blob/ceb471cfde901d47e705dd32abba1ea8eab269fa/libavformat/utils.c#L283]
 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?
