Hello,

while tracking some time stamp issues unique to FFmpeg I noticed 
AV_Time_BASE(_Q) being present quite often, which appears to be a value to 
define time stamps in milliseconds. Tracking it back to its origin I could find 
very little to no information about why this value was chosen. All I know so 
far is that it was chosen for compatibility with very early versions of FFmpeg.

Does FFmpeg require this value to be a full millisecond? Or is it possible to adjust this 
to microseconds and "fix" many of the time stamp issues that occur? While it 
seems to be possible to work-around this issue on a muxer/demuxer level, the underlying 
issue in FFmpeg would still be present. At the moment, most non-integer ms framerates and 
sample rates end up performing weird without post-processing.
