Hi,
I am having trouble understanding the following SMIL 2.0 test case.
Could some one tell me why "video2" begins to be shown only at 9 sec
and not at 5 seconds?
"video1" begin is resolved to 10s document time, for (both intervals of
par),
then "video2" begin is resolved to 5s document time. Then why is "video2"
shown only at 9 sec and not from 5 seconds as expected?
TIA,
John
