Bertl
morning folks!
06:48
Bertl
mithro: ah, the typical setting is 0x92 for the IO pins
06:48
mithro
Bertl: is there anywhere?
06:49
Bertl
IO1 = EQ0, IO4 = EQ1, and IO7 = EN
06:51
mithro
Bertl: So you are pulling EQ0,EQ1 and EN high, while leaving everything else low?
06:51
Bertl
i.e. power the 5V output and set the equalizer to 6dB
06:51
Bertl
yup, that is the default setting for now
06:52
Bertl
note: we don't do DDC or CEC yet
06:52
mithro
Okay
06:54
mithro
Bertl: Should we be pulling CEC up or down if unused?
06:54
Bertl
that is a very good question, currently we do not populate D1 and R8 on the modules
06:55
Bertl
(and it seems to work)
06:55
mithro
Isn't D1 & R8 for ESD protection on the CEC?
06:55
Bertl
but from what I've read, CEC should be pulled up to 3V3 via the diode
06:56
Bertl
it's not a typical ESD protection, it's mainly a pullup
07:01
Bertl
the diode works as back drive protection, and is often replaced by a mosfet
07:01
Bertl
R8 is the typical 27k pull-up used in CEC circuits

Is the order in the matrix (RGB) correct? https://wiki.apertus.org/index.php/File:Mat4-conf-illustration-01.jpg I think it's the other way round.
10:43
Bertl_oO
please get the latest mat4_conf.py, it has the 'normalized' order R,G,B,X (or R,G,B) if you use 3x3
10:44
Bertl_oO
the order of mat4_conf.sh is indeed X,B,G,R
10:44
BogdanXor
joined the channel
10:45
Bertl_oO
i.e. the first four values control the 'unused' result
10:45
Bertl_oO
while the second, third and fourth quadruple control B, G, R respectively
10:46
Bertl_oO
this will probably change once again in the future when we start using different G values
10:47
Bertl_oO
i.e. when the debayering is not just combining four values

What does "frames per buffer" mean in a video sense?

Bertl_oO: without context, im trying to translate Clementine
13:49
Bertl_oO
without context it doesn't make sense to me
13:50
Bertl_oO
a single buffer with several frames in it maybe
