avsync-lib: pattern check limited in one frame room [1/1]
PD#SWPL-47065
Problem:
AV Sync 60Hz video on 59.94 display will cause longer
than expected AV-sync diff range. NTS failed.
reason is the pattern check did not have an up pts limit
to keep the pattern, cause diff accumulated to bigger number
then reset.
Solution:
*set upper limit to one v-sync inverval room for the pattern
adjustment, that is the common pull down/up method
*Added env setting AML_AVSYNC_DEBUG_LEVEL option to overwrite
the default settings from other module for convinient debug
