Okay. My files all come from the same source. So if I check to see
if timebase = 1/framerate, and if it is, then I can use pts or
best_effort_timestamp as the frame numbers (assuming stream.start_time
is zero).
Why would timebase be anything other than 1/framerate? I thought timebase
was in fact defined as 1/framerate. That's what avcodec.h says.
