cr1901_modernmithro: Has not changed since "whenever I last talked to you". And won't be able to work on it until tomorrow night at earliest due to prior engagement.00:26
CarlFK[m]mithro (IRC): do you know where the issue is for the serial connection blocking the video stream?00:33
CarlFK[m]I want to compare error messages.00:34

CarlFK[m]thanks - didnt know you could search across repos like that00:58
mithroCarlFK[m]: It's a bit of a hidden thing01:00
mithroCarlFK[m]: can actually search across all of github :-P01:00
CarlFK[m]mithro (IRC): what do you call it when you see this in dmesg:01:06

mithrojea: I'm pretty sure there is an issue with that pull request01:27
mithrojea: The output is image.bin?01:27
jeamithro: I'll check01:28
mithrojea: I'm building now locally to test myself01:28
mithroGuess I'm wrong...01:38
mithroFlash image: build/opsis_video_lm32/flash.bin01:38
jeaoh01:38
mithroIt's a bit weird that "make image" creates a flash.bin....01:38
jeaso flash.bin is the right one?01:38
jeaI remember seeing an image.bin previously, but maybe that was the prebuilt firmware?01:39
mithroYes01:39
jearight01:39
jeadeeprave just ran it, and it worked with flash.bin01:39
jeaneeded to do a reset-opsis first because it must have been in the wrong mode01:40
mithroOkay01:43
mithromerged it...01:43
mithroI'm learning about waf and if we should be using it for HDMI2USB :-P01:44
cr1901_modernmithro: So, my strong opinions aside about waf, it prob is a good fit if you can get past the shitty learning curve01:50
cr1901_modernIf SCons used python3, I'd reimplement the whole damn build system for you01:51
cr1901_modernB/c I actually enjoy that01:51
cr1901_modernmithro: How is waf looking so far?01:54
mithrocr1901_modern: Looking pretty good....01:54
cr1901_modernmithro: Rereading the manual... maybe it's not as bad as I remember, but I def think "the waf book" is still difficult to read01:58

rohitksinghmithro: pong02:14
mithrorohitksingh: Have you played with getting audio out of the TOFE Milkymist board?02:15
rohitksinghmithro: Nope. I haven't worked with TOFE Milymist board at all02:16
mithrorohitksingh: The audio codec on the Milkymist board is the same as the one Numato has a pmod module for IIRC?02:16
cr1901_modernmithro: I don't think we need to replace the litex/migen.build components. Since waf is python3, just import migen/litex and call into that code instead? Use the python code to get rid of the makefiles and bash dependencies02:17
rohitksinghmithro: I guess so. The current sample code for the audio expansion board has only audio loopback code02:17
mithrocr1901_modern: I'm more thinking the Makefile we have and the scripts in scripts...02:18
mithrorohitksingh: Loopback code?02:18
mithrorohitksingh: As in the microphone is connected to the speaker?02:18
rohitksinghyeah...LineIn to LineOut loopback02:18

mithrocr1901_modern: You are not allow to do anything until I have working spi flash stuff :-P02:20
mithrorohitksingh: So the same from there should work on the Milkymist board assuming we get the pin mapping right?02:21
cr1901_modernmithro: Well Idk Waf :P. I know SCons (what Waf forked from). But I fully support the idea02:21

jeais there a specific name for the title svg file? or just put a .svg file in that folder?05:13
CarlFK[m]there is a field in Client - fill that in with the filename (and path under bling05:15
jeaok05:16
CarlFK[m]there are 2 sorta unit test like things you should run:05:19
CarlFK[m](veyepar) [email protected]:~/src/veyepar/dj/scripts$ python ck_setup.py05:19
CarlFK[m]that looks at client.title, makes sure the svg exists05:20

jeaCarlFK[m]: I ran the ck_setup.py script and it has loaded different config to what I expected it to05:43

*** SamSagaZ__ has joined #timvideos15:36
CarlFK[m]tumbleweed paddatrapper - any idea why hdmi2usb.hex isn't being built by travis?16:02
paddatrapperCarlFK[m]: In the prebuilt repo?16:03
CarlFK[m]right16:03
tumbleweedI think because when the build was reorganised atlys was forgotten16:04
CarlFK[m]so add a hook to email paddatrapper  so he will build it for us.  easy :)16:05
CarlFK[m]I was hoping a typo or something was discovered16:06
paddatrapperhehe, probably should be added to the Travis build of the FX2 repo16:07

Choco31415So far I've been poking around to see what the streming setup should be.23:26

CarlFK[m]have you tried voctomix ?23:48
Choco31415CarlFK: I'm still leaning towards OBS. It can capture audio, mix the presentation and camera streams, and record everything live.23:50
mithropaddatrapper: I'm looking at the version / commit issue at the moment23:52
Choco31415OBS is also free and open source, if that counts for anything.23:52
