about IAMVideoProcAmp test. of HCT(video capture driver)

I am watching ERRORs and WARNINGs of HCT(12.1.01) Result for our video
capture driver.

(A) is a part of IAMVideoProcAmp test.
I don't understand (B).
Our capture device didn't catch 128, but 1 as "High + 1"
from what I watched CATC's log.
Would do you have such a errata as this ?

(A)
Testing property Contrast
Maximum Value 127, Minimum Value 0

ProcAmp_Test Propset :Contrast, Walk from low to high (Valid)

Thanks in advance

Dear Mr. Watanabe,

> Would do you have such a errata as this ?

Not that I have found.

> WARNING: ProcAmp Property Contrast: Could set to Invalid Range (0128)
(MIN:0, MAX:127) ......(B)

Please put a break point in your SetPropertyCtrl() code and step through
the range checking section.

> Our capture device didn't catch 128, but 1 as "High + 1" from what I
watched CATC's log.

128 = -1 for signed byte values

Try changing "Maximum Value 127" to 126 and 129 to test if there is a sign
issue going on.

Hope this helps.

Thank you,

Um, no, 128 unsigned byte is -128 as a signed byte, not -1. -1 would be
255.

I tested HCT , 3 pattern.

contrast max is 127 ... HCT.A, WinDbg.A
contrast max is 126 ... HCT.B, WinDbg.B
contrast max is 128 ... HCT.C, WinDbg.C

HCT.* is parts of HCT log.

I wrote DbgPrint in SetPropertyCtrl's entrance.
WinDbg.* is parts of WinDebug log.

Would you think "High + 1" of HCT program is "1" ?
"1" is Invalid ?
