| nueces | there is something more that I could test here? | 00:00 |
|---|---|---|
| mithro | Hey nueces | 00:03 |
| nueces | hi mithro | 00:03 |
| mithro | I'm currently on my phone, so can't really help debug at the moment | 00:03 |
| mithro | Will be around in an hour | 00:04 |
| nueces | no problem, I could setup the environment other day | 00:04 |
| mithro | nueces: were you following the improved instructions? | 00:05 |
| nueces | I'm going to try to use a different camera | 00:05 |
| nueces | mithro, both , the new and the old :) | 00:06 |
| nueces | switch the mode and later the order to load the gateware and firmware from the previous | 00:06 |
| nueces | one | 00:07 |
| mithro | Btw, do you have redmere cables? The fact that you are getting a resolution in the prompt is a good sign that things are working | 00:07 |
| nueces | mithro, I don't have redmere cables here | 00:08 |
| mithro | Camera's are a lot more fussy / random then computers | 00:08 |
| nueces | but the other day I use the debug and see the WRE was 0 | 00:08 |
| mithro | Yeah, zero WER is a really good sign | 00:09 |
| mithro | I'm hoping that after we finish the liteXXX upgrade stuff, we can work on improving the HDMI input debugging situation | 00:10 |
| mithro | cr1901_modern is already working on one part of that | 00:10 |
| mithro | (Detecting and determining the pixel clock frequency.) | 00:11 |
| *** nueces has quit IRC | 00:14 | |
| mithro | cr1901_modern: did I ever link you to my i2c modules I was working on? | 00:14 |
| mithro | At some point I want to get back to that | 00:15 |
| mithro | Eventually I hope to replace the current EDID implementation with that code | 00:16 |
| mithro | As it has things like test benches | 00:17 |
| mithro | And it should be easier to both harden, optimise and have a more flexible boundary between the gateware and the soft code | 00:19 |
| mithro | We really need to come up with a good way of figuring out the FPGA resource usage of a block so we can better understand design trade offs | 00:21 |
| cr1901_modern | mithro: No you didn't. Perhaps that be part of the trouble with the current code? | 00:23 |
| cr1901_modern | mithro: Forgive me that I'm hesitating/freaking out b/c NVIDIA driver is garbage when I attach my board | 00:25 |
| mithro | Well my phone is already going flat :-( | 00:27 |

| CarlFK | mithro: did that code I wrote to do automated tests ever get checked into a repo? | 01:08 |
| mithro | CarlFK: you put it up on a gist | 01:09 |
| CarlFK | can we put it in a repo so it can be found | 01:09 |

| CarlFK | great.. except sometimes you sleep ;) | 01:10 |
| CarlFK | more interesting question: why does my lcd sometimes say '720p' and sometimes '1280x720 60Hz' ? | 01:12 |
| mithro | CarlFK: I can't think of a good repo to put it in | 01:12 |
| mithro | CarlFK: NFI? | 01:12 |
| cr1901_modern | mithro: You've answered this before, but you designed the Opsis hardware, correct? Does that including doing the unenviable PCB layout? | 01:16 |
| mithro | cr1901_modern: No, the Numato guys did the PCB layout under my direction | 01:17 |
| cr1901_modern | That's cool... was just wondering. I wonder how much it costs* to get a custom board designed... | 01:20 |
| cr1901_modern | *More money than I have | 01:20 |
| mithro | cr1901_modern: They didn't charge anything, they make the money from selling the board | 01:26 |

| CarlFK | git pull | 01:50 |
| CarlFK | Already up-to-date. | 01:50 |
| mithro | CarlFK: I pushed some changes earlier in the week which fix your breaking it | 01:50 |
| CarlFK | I am guessing I need to "sudo make install something" | 01:51 |
| CarlFK | but I have to run to meet a friend | 01:51 |
| mithro | CarlFK: have you set your path so it sees the bin directory? | 01:51 |
| CarlFK | can you add to the README how you think the install should go, I can test on a fresh os when I get back | 01:52 |
| mithro | CarlFK: "make setup", everything works | 01:52 |

| Guest97527 | Yo anyone online got a question to ask about hdmi2usb. | 06:17 |
| Guest97527 | I have a question to ask rather* | 06:17 |
| *** aom_ has joined #timvideos | 06:43 | |
| mithro | Guest97527: ask and hopefully someone will get back to you | 06:44 |
| Guest97527 | Well i guess the gist of it is I am in need of a displayport 1.4 frame grabber with a usb 3.0 output, now obviously the opius doesnt support this, and the only currently available alternatives are in the form of commercial pci-e capture cards running upwards of 2 grand a pop | 06:47 |
| Guest97527 | Is it possible for me to design my own board and adapt the hdmi2usb firmware to it. | 06:47 |
| mithro | Guest97527: It wouldn't be a small project | 06:49 |
| mithro | Guest97527: And would require a lot of new development | 06:49 |
| Guest97527 | I thought as much bugger. | 06:49 |
| mithro | We are in the process of doing that - but it will be quite a while before we can do something like that | 06:50 |
| mithro | Guest97527: why do you need USB 3.0 output? | 06:50 |
| mithro | Guest97527: I assume you want a very high resolution capture? | 06:51 |
| Guest97527 | usb 3.0 has the bandwidth required to output uncompressed 4kp30 | 06:51 |
| Guest97527 | Around 6-7Gbps if i recall | 06:51 |
| mithro | Guest97527: your computer is unlikely to be able to do anything useful with that data | 06:51 |
| mithro | But the apertus team is interested in those types of resolutions | 06:52 |
| Guest97527 | Ill be pushing it into a dual e5-5645 setup (so 24 cores, x58 platform xeons) and encoding the feed using x.264 | 06:52 |
| mithro | Guest97527: you are much better going with PCI-Express rather than USB3.0 - you won't have such high overheads | 06:53 |
| Guest97527 | My other idea was to just grab a board with a dp 1.4 input and 4 hdmi outputs and split the stream into 4 1080p60 outputs to be captured individually, which is a little simpler (can use already made products) but a messy solution | 06:53 |
| Guest97527 | to be reassembled on the otherside ofc. | 06:54 |
| mithro | Guest97527: You could probably do something like that with the Opsis and a custom expansion board | 06:54 |
| mithro | I've already got a plan for an expansion board which adds more HDMI outputs | 06:55 |
| mithro | Guest97527: but we really need more developers and funds | 06:55 |
| Guest97527 | Yeah thats always the issue, well anyway thanks for the help mate | 06:55 |
