xfxfmithro: also, i assume you will be at pycon au?  my intention will be to use the hdmi2usb's there so i'll likely need some help, although it won't need to be the whole conf, more troubleshooting help03:49
CarlFKxfxf: I need 2 more HD cameras.  What is the model you picked out?  (assuming you still like it?)04:06
xfxfAnd yes still like04:09
xfxfI'd be considering those cameras CCC suggested that do x264 over usb04:10
*** cr1901_modern has quit IRC04:23
CarlFKoh, yeah.. that would simplify things. no need for a pci card04:23
mithroPCI Card?04:24
mithroWith x264 you'll have to decode it before it can be used in voctomix04:24
*** cr1901_modern has joined #timvideos04:28
CarlFKmithro: the blackmagic card I use to capture the local camera.04:30
CarlFKI am guessing my vocto core box has enough cpu to decode.04:31
CarlFKthe atlys did come out of the box and someone was interested in it, but that's all the attention it got tonight.04:32
CarlFKI need to go shopping so we can have breakfast in 9 hours04:32

ssk1328mithro: When do you think you, you can help me setup Opsis?09:35
mithrossk1328: you got time in the next 20 minutes?09:51
ssk1328I have already generated bit stream for Opsis09:56
mithroHave you powered on your Opsis?09:58
ssk1328No, not yet09:59
mithrossk1328: that would be step 110:00
ssk1328mithro: Any jumper configuration I should worry about10:02
mithrossk1328: it should ship in the default configuration10:02
ssk1328mithro: The power adapter doesn't seem to be compatible. Can I power it using USB?10:06
mithrossk1328: no10:06
ssk1328The 12V power adapter I got doesn't fit itself in the slot.10:06
mithrossk1328: well, that would have been something to check earlier10:11
ssk1328mithro: The adapter seems to be stable now.10:15
mithrossk1328: ?10:15
ssk1328It was a bit loose earlier. Should I connect the HDMI and USB cables as well?10:17
mithrossk1328: Does it power on?10:17
ssk1328Led is on. And a blue led turned on at the start and off after ~5secs10:18
mithrossk1328: okay10:18
mithrossk1328: plug in the USB and see what ID the board appears as10:18
ssk1328What device name should I look for. I am using lsusb, about ~10 names popped up.10:21
mithrossk1328: Have you looked at the documentation?10:22
ssk1328Bus 001 Device 006: ID 16c0:06ad Van Ooijen Technische Informatica10:22
mithrossk1328: what does dmesg show?10:23
ssk1328I get this as one of the line10:25
ssk1328usb 1-4: SerialNumber: hw_opsis10:25
mithrossk1328: That doesn't help me at all10:26
ssk1328What exactly should I try to look? dmesg outputs a lot of stuff!10:26
mithrossk1328: Put the whole output into a pastebin10:27
ssk1328mithro:  There are about 300-400 lines total10:29
ssk1328Or maybe more!10:29
mithrossk1328: that is why I said put it into a pastebin10:29

CarlFKssk1328: good: Found UVC12:24
CarlFKand good: ttyACM012:24
CarlFKssk1328: also, do this: watch -d lsusb12:25
CarlFKwatch will run the command every 2 seconds, -d will highlight the differences12:25
ssk1328CarlFK: I didn't notice it was you :P12:26
ssk1328CarlFK: What am I supposed to look for in the watch -d lsusb12:27
CarlFKssk1328: it should help you see what gets added when you un/plug in the usb cable12:27
ssk1328Ohh. Okay.12:28
ssk1328CarlFK: Can I upload the bit stream now?12:28
CarlFKssk1328: yes12:29
ssk1328CarlFK: Isn't the Opsis pre loaded with some standard bit stream?12:30
CarlFKUVC - you should be able to see a test pattern with12:30
ssk1328CarlFK: at which HDMI_OUT?12:31
CarlFKmplayer tv:// -tv driver=v4l2:device=/dev/video112:31
CarlFKboth hdmi 0 and 1 will also output the color bars test pattern12:31
ssk1328Lets ee12:31
CarlFK(ignore the 1,2 lables. you will see later that we should call them 0 and 112:31
ssk1328CarlFK: I see the pattern Yay12:33
ssk1328CarlFK: The link here says, I need to take out some jumpers before flashing anything12:39

ssk1328CarlFK: Does it refer to atlys board?12:41
CarlFKssk1328: yeah, that's old.12:42
CarlFKhere are my *notes* on how I flash it

CarlFKit might run a script, but I cut/paste lines from it into the prompt12:46
CarlFKv=v0.0.0-699-gb505665 # noise on hdmi out and encoder stream12:46
CarlFKthere is now a symlink to that12:47
CarlFK# repeat these 3 lines until it works12:48
CarlFKI should have pasted the lines that show you what works looks like, and the error I get if it doesn't12:49
CarlFKI have no idea why it doesn't work every time12:49
