The slow startup seems to have happened between 9/30 and 10/1.
In the startup messages I see:
2004-11-12 13:18:34 Using protocol version 13
2004-11-12 13:18:43 detectInterlace(Detect Scan, Detect Scan, 29.97,
480) ->Interlaced Scan
2004-11-12 13:18:43 Interlaced: Interlaced Scan video_height: 480 fps: 29.97
As you can tell, it took 9 seconds to go from Using protocol message
The diffs for this day show only ringbuffer.cpp -- going from 1.104 to 1.105
Somebody have any insights into what this code is doing?
