[mythtv-users] Commercial Detection

[aaron]

Hi,
I don't mean this to be a complaint, but rather more of a data point...

On Jan 17, there was a fairly major revamping of the way commerical
detection works. I found that with this new code, detection was
working better than I ever imagined was possible.

Then, on Jan 23, there was a modification to the "brightness
thresholds". With this change, the commercial detection was still VERY
good, but not as good as the Jan 17 version.

Since then, other changes were made, including some sort of
aspect-ratio detection, I think. I've found that with the current
version, detection isn't as good as it was even prior to Jan 17.

It works really well on some shows, especially ones that are
letterboxed, but on others it looks almost random sometimes. A couple
of shows that used to detect really well no longer detect well. For
example, Jeopardy (you can stop laughing now :) . The first couple of
breaks detect fine, but the Final Jeopardy round is detected as a
commercial now so that, essentially, the show ends after Double
Jeopardy. It does this consistently now, night after night. With the
"old" version of the commercial detection, all the commercials were
detected correctly.

I don't know what to suggest for how to improve it. I'm sure the
current version is working great for some people. But for me, it's not
as good as it used to be. And it's not as good as I know it can be.
