build: fix 32bit builds (#7510)

Browse source 
ensure the correct type is passed to std::clamp and std::max int64_t is
different on 64bit compared to 32bit, also in presentationtime
tv_sec is __time_t and on 32bit its a 32bit type so right shift count >= width
of type. so only bit shift on 64bit. and avoid potential nullptr deref
in the for loops, check for .end() before *it <= endID.
