| CarlFK[m] | mithro (IRC): very out of date. hdmi2usb and related software is the only active project | 00:34 |
| mithro | CarlFK[m]: you where doing to take some stuff from it and then we are going to delete it | 00:34 |
| CarlFK | mithro: oh right - sure. delete it | 00:35 |
| CarlFK[m] | mithro (IRC): just had an idea: when hdmi2usb gets a screen in some other res than expected (like my box's post is doing 640x480) put that into the 1280x720 buffer, either in the corner or centered. | 00:46 |
| mithro | CarlFK[m]: Yeah would be a nice feature | 00:46 |
| CarlFK[m] | so that I can see what is going on. | 00:47 |
| mithro | CarlFK[m]: it requires a bit of magic to make work | 00:47 |
| mithro | CarlFK[m]: Have to reset the data pointer after each line rather than after each frame | 00:47 |
| CarlFK[m] | mithro (IRC): k - I'll add it to the list - wanted to make sure it wasn't already somewhere | 00:47 |
| CarlFK[m] | seems easier than scaling. | 00:48 |

| faulteh | hello.. i am trying to figure out what i'm missing to get the v4l encoder to work on ubuntu to display it with mplayer or vlc | 09:19 |
| anshul | hi | 09:19 |
| faulteh | hi anshul | 09:20 |
| faulteh | i do 'x c p e' and 'encoder on' on my opsis but mplayer just gives me v4l2: ioctl set format failed: Input/output error | 09:20 |
| faulteh | and similar with vlc | 09:20 |
| faulteh | tried it with a bunch of firmwares too v0.0.3-1045 v0.0.4-74 and v0.0.4-148 | 09:25 |
| faulteh | switching of hdmi inputs and outputs is working ok so i know things are working generally | 09:25 |
| faulteh | but ive not used the encoder before today | 09:26 |
| *** anshul has quit IRC | 09:26 | |
| CarlFK[m] | Faulteh: sec... let me dig that up | 09:27 |
| faulteh | excellent thanks | 09:30 |
| faulteh | if i can get the encoder working by the weekend ill probably get a second opsis so i can have two in our radio club's new DTV studio so we can start broadcasting at 720p | 09:31 |

| CarlFK[m] | disconnect your terminal app from the serial interface | 09:31 |

| CarlFK[m] | paddatrapper (IRC): it is on the page of useful hardware, right? ;) | 16:43 |
| CarlFK[m] | along with magic cables and cases. which I can't find. | 16:44 |
| CarlFK[m] | "what cables should I buy?" should be top of the FAQ | 16:44 |
| CarlFK[m] | well, what box maybe is even more likely. | 16:44 |
| paddatrapper | CarlFK[m]: the HDMI cables should be there (if not, I'll add them) | 16:45 |

| CarlFK[m] | paddatrapper (IRC): im just not sure where "there" is. unless this is it: https://opsis.hdmi2usb.tv/getting-started/case.html | 16:46 |
| paddatrapper | CarlFK[m]: I thought you were talking about Debian video team docs. Hadn't thought to check the opsis docs | 16:47 |
| CarlFK[m] | oh right - i didn't think of the dv docs - they are too new for me | 16:49 |
| CarlFK[m] | I like how this power supply page does not say what power supply can be used ;/ https://opsis.hdmi2usb.tv/getting-started/power.html | 16:50 |
| CarlFK[m] | there is a header behind the usb-B port that has the 5v coming from the host - I wonder if I can use that to drive the odroid c2? | 16:52 |
| paddatrapper | It says 12V@2A DC barrel or PCIe 6 pin | 16:53 |
| paddatrapper | IIRC, that's how we did it at pyconza | 16:53 |
| paddatrapper | (powered the odroids from the 5V headers) | 16:54 |
| CarlFK[m] | neat - | 16:54 |
| CarlFK[m] | which power connector did you use on the c2? | 16:54 |
| paddatrapper | tumbleweed: ^? | 16:54 |

| CarlFK[m] | thats my test rig | 17:28 |
| CarlFK[m] | the C2 isn't hooked up to anything | 17:28 |
| CarlFK[m] | the black wire/barrel is switched 5v for an Atlys in its on box | 17:29 |
| CarlFK[m] | own box | 17:29 |
| CarlFK | tumbleweed: my exact Q: can I use the 5v on the usb header on the Opsis board to power the c2? | 17:32 |
| CarlFK | I don't see why not. | 17:33 |
| CarlFK | at 2am we concluded it wasn't even hooked up to anything other than the usb-b port. like it doesn't go anywhere into Opsis land. | 17:33 |
| CarlFK[m] | oh wait.. the other end of that cable will be plugged into the C2. um... | 17:34 |
| CarlFK[m] | yeah, never mind that plan. | 17:35 |
| shivm28 | CarlFK: I think "flash.bin" file is missing for the default settings. And things won't work without that. | 17:35 |
| CarlFK[m] | shivm28 (IRC): or flash.bin has a new name | 17:36 |
| shivm28 | I will try to run the script for some other platform. | 17:37 |
| CarlFK[m] | shivm28 (IRC): I have a local checkout of that repo (it is huge!) | 17:38 |
| CarlFK[m] | and flash.bin stopped a while ago | 17:38 |
| tumbleweed | CarlFK[m]: dunno | 17:39 |
| CarlFK | tumbleweed: I do. No. unless the c2 can power itself from it's own usb-a port ;) | 17:40 |
| tumbleweed | CarlFK: the opsis does have a 5V power rail, the question is how much spare capacity there is | 17:41 |
| CarlFK | tumbleweed: im trying to find 5v on the Opsis so I don't have to hook up a 2nd PS for the C2 | 17:41 |
| tumbleweed | (or I assume it does) | 17:41 |
| CarlFK | I hear PS1ers say "use a $1.20 (or 12 cent?) power do-dad to get 5v off your 12v supply." | 17:42 |
| CarlFK | but A) I haven't seen a part number and B) i would rather not have to figure out where to mount it. | 17:43 |
| CarlFK | plan B: https://www.ebay.com/itm/AC-to-12V-5-Volt-DC-Power-Supply-Adapter-w-4-Pin-Molex-Connector-Plug-SS34W1205-/301938683326 | 17:50 |

| CarlFK[m] | it just fits. | 18:17 |
| CarlFK[m] | not sure how I feel about an iec plug 'there' | 18:17 |
| tumbleweed | according to https://opsis.hdmi2usb.tv/getting-started/power.html - the opsis 5V power rails don't have much power - not enough for the odroid | 18:18 |
| tumbleweed | so yes, you need to do your own thing | 18:19 |
