Hmm,
I sent this last night but it never showed up on the list,
So I am resending
...
Fixed it myself :)
The patch is attached and it replaces the previous patch and
addresses all four issues.
1) in strict mode - treat frames as blank only if logo is absent
2) more fixes for the "long long" issue
3) fix for "white frames" triggering commercials
4) do not detect commercials less than 60 sec long, in the middle of a show
PS
I also highly recommend changing the default max and min comm break lengths
-#define MIN_COMM_BREAK_LENGTH 60
-#define MAX_COMM_BREAK_LENGTH 485
+#define MIN_COMM_BREAK_LENGTH 55
+#define MAX_COMM_BREAK_LENGTH 335
The combination of the above changes seems to detect at 99% accuracy
with no false positives so far for me.
PPS
