CarlFK[m]no, not yay.  that should be 1280x72000:07
CarlFK[m]output1: [email protected] from pattern (underflows: 1842238)00:15
CarlFK[m]I think underflows wrapped00:15
CarlFK[m]input1: 10x720 (@74.24 MHz) (capturing)00:16
CarlFK[m]dvisampler0: IDELAY busy timeout (%hx %hx %hx)00:47
CarlFK[m]I'm guessing that should have hex thins00:47
CarlFK[m]dvisampler0: phase init failed00:47
CarlFK[m]dvisampler0: giving up00:47
CarlFK[m]thats new00:47
mithroCarlFK[m]: 65MHz pixel clock definitely looks like 1024x76801:41
mithroCarlFK[m]: 720p is normally 75MHz01:41

mithroCarlFK[m]: Roughly, 65MHz ~= 1024x768, 720p60 ~= 75MHz, 1080p60 ~= 150MHz03:53

CarlFK[m]mithro - ah, I got confused with .. the fps or refresh rate - whatever the 60 is in: mode 9: 1280x720 @60Hz04:14
mithroCarlFK[m]: FYI - the (@65.01 MHz) is referring to the pixel clock not the refresh rate...04:22
*** sb0 has quit IRC04:23
mithroCarlFK[m]: You should be able to detect a pixel clock of up to like 800MHz which is like 4k04:24
CarlFK[m]mithro (IRC): did tumbleweed list what revs had a bug?  so that I can try that rev and maybe live with the bug?04:25
CarlFK[m]like I don't need 2 inputs04:25
mithroCarlFK[m]: No, I think he was naughty and didn't record a bug04:26

CarlFK[m]that's the vga box color bars04:28
CarlFK[m]er, that's what both the Opsis and Atlys do with the vga box color bars04:29
CarlFK[m]im guessing there is a setting on the box I need to flip04:29

CarlFK[m]mom;s tv - displaying what it sees: 720p 60hz04:32
CarlFK[m]fixed it04:34
CarlFK[m]"hdmi data on/off/auto"  turned it off.04:34
mithroYes, we don't decode HDMI data04:41
mithroThat would cause what you are seeing04:41
CarlFK[m]whew.  I was worried my new rock solid device was not as rock solid as I thought04:43
CarlFK[m]I was also using it to test 'does this firmware rev work' and getting all sorts of confused.04:44
felix_after (not too successfully) trying to get some professional-ish equipment working, i finally understand why people could want to be able to get detailed information about video formats and timings on interfaces (except for just wanting to know all the details about things). why is the professional and proprietary stuff i have here so bad from user perspective in terms of usability? /o\04:45
felix_(currently trying to get a decklink card working in a test setup)04:46
CarlFK[m]felix_ (IRC): any chance it is this one?04:47

tpbTitle: Blackmagic Design: DeckLink Tech Specs (at www.blackmagicdesign.com)04:47
CarlFK[m]wait.. that doesn't really show the one ..04:47
CarlFK[m]"DeckLink Mini Recorder"04:48
felix_no, the decklink 4k pro card (dual 12g sdi in and out) that is somehow not listed any more on their website (the 8k pro looks very similar, but has 4 bidirectional 12g sdi ports)04:50

felix_i meant with detailed information to be able to debug what actually happens on the wire05:03
CarlFK[m]mithro (IRC):   git describe: v0.0.3-1045-c9-dirty looks ok.    tested with 1 in and 2 hdmi out + encoder out05:31
CarlFK[m]there are 4 revs after that, but the dont contain opsis/hdmi2usb/lm32/image-gateware+bios+firmware.bin05:36

CarlFK[m]nothing really - just what I cut/pasted the first time was a little confusing06:24

tumbleweedto put it back into the normal mode it boots up in21:09
