Life took over but...looks like I found the solution by obsessively performing more searches. I found another post of someone with a simi lar issue and they solved it by increasing the crop value. It does intrigue me since the bottom crop is only 5 and the detection zone extends beyond the black border. On the other hand, in order to get the same zone for the top border I have to increase the crop value to 28.

Hope this has been addressed and if it has, I apologize. Finally got my setup working again after borking it due to my dumbassery a year ago from just unplugging the RPi instead of powering it down via OS. Have it working again with the latest Raspbain Stretch Lite, RPi 3B with Arduino and using WS2812 LEDs and regular Hyperion.Everything is working really well except for Black Border Detection. I have a threshold of 0.2 and using the default mode.

In movies with black borders, the side and bottom LED rows work amazingly well except the top row, which will remain pretty faint, even if the whole screen is showing much of the same level of brightness. If the scene pans down, the same image that would make the bottom LEDs very bright will barely light up the top row of LEDs at all. The scene has to be very bright for the top LEDs to visibly react, oftentimes they don't. I have replayed the same scenes and observed the LEDs themselves and they remain pretty faint, and if it does show a color change it still remains faint. I have no problem at all with full screen movies.

At work ATM, so I will post my config file as well some pic of how the LEDs look like when I get home tonight.

I installed OSMC on my Pi along with the STK1160 and the results so far have not been impressive. The scenes have to be very vibrant or very uniform in color in order for Hyperion to light up anything. Did not have this problem with OpenElec and the Fushicai card. I may have to try recalibrating again since I just copied the old config file. I will install the full version of Raspbian tonight and see what results I get. Keeping my fingers crossed.

I hope the author of the Fushicai driver can implement v4l2 controls but I am not holding my breath for long. I understand they are doing this out of their dedication for the Pi and Hyperion so we have not right to demand - as I've seen on other forums for other products - that they fix the driver. I don't know enough about Linux, the drivers, control utils and compiling to really do much.
I am curious as well how people are getting Ambilights that are calibrated if there is such a huge saturation problem with the Fushicai. It would be helpful to get specifics such as what HDMI to RCA converter they are using, where they purchased their EasyCap in order to see if a common denominator can be found between those who have oversaturated/incorrect colors vs those who have correct colors.

My STK was finally delivered today so I will post my results/experience after I install it Saturday or Sunday.

Thanks. I found one from a US seller but I do agree that overall it it annoying after spending so much time on it and getting everything right that this happens. Can I ask where you got your Fusichai based capture card from? I got mine from an eBay seller in China after I could not find a U.S. seller that could guarantee that the chip as a Fushicai or was just asking for too much.
I checked the MediaPortal forums which is where I found the guide to follow in building mine. The author says he got his from a German site and it does not have the problem with color oversaturation.

In the meantime I will try to hunt down a grabber with the stk1160 and hopefully this issue can be addressed later. I'd like to see for myself how bad the blue flashes are and see if I prefer it to the oversaturation. I did a small search for an stk1160 based capture device but all results I found were about sellers who stated theirs was NOT the stk1160 but the Fushicai.

I will have to take a look when I get home but I am having a similar problem with the same hardware grabber and some WD2812B LEDS, the colors seem oversaturated so it causes light purple to be seen as blue and quite often skin tones and blonde hair and several shades of orange are output as deep red. I have calibrated colors using the Color Calibration guide and the RGB patter color and all colors come out fine but during actual video playback I get this problem. I will post a screenshot of my output and screencap when I get home cause this is....frustrating. :crying:.

I'm still playing with my configuration but I've found that your surroundings will can affect how your colors look. I was working with my setup in the bedroom so it was hooked up to the PC and did some basic color calibration. The walls in the bedroom are white so I got it as fairly easy to get a good color reflection but when I took the setup into the living room which has a light tan color it made my colors look different and has presented a whole new color calibration problem for me.

Plus, all LED strips, no matter what kind they are, have different behaviors and different manufacturers with different quality standards compound the problem even more. I know the easy part was building the hyperion setup, the hard part is going to be getting the colors to my liking. Also keep in mind that everyone perceives colors differently so what may look like orange to you may look reddish-brown to someone else.
