Hi,
I have made a webtv application. It reads filenames and lengths in seconds from
mysql db on application start, create 18 (3x6) playlists, and starts them. I
have converted each video to 3 different resolution, and I start the full
playlist from 6 differnet position. channel_high_0 uses the 640x480 videos, and
starts from the 0. file. channel_high_5 also uses 640x480 videos, and starts
from the 150. file. channel_med_5 uses 320x240 videos, and starts from the 150.
file.
It works fine for a time, but then some playlist steps to the next file too
late.
At channel_*_3 the 40. playlist next was at 2007-06-27 03:52:23 - 24.
The 40. video length is 1461 seconds. Next change was:
320x200 and 160x120: 2007-06-27 04:16:44-45 - this ok.
640x480: 2007-06-27 04:32:14 - this is 929 sec later than scheduled.
video41 length is: 1292 seconds.
There were some Quartz error in this time window, so they may cause the problem.
Other playlists works fine now, but this error always occure in 1-2 channels
This error doesn't depends on load, because it came when there was only 50-60
user connected to the server (max user was 565 previously).
trunk revision is 2146, but this error is exists in 0.6.1 also.
Regards,
Jozsef Inancsi
