| CarlFK | mithro: why did you remove gateware-$(TARGET) from https://github.com/timvideos/HDMI2USB-misoc-firmware/commit/dcfeb7d8ce50aaac1120ec3b33e20d1e3c241944#diff-b67911656ef5d18c4ae36cb6741b7965L59 | 03:13 |

| mithro | CarlFK: I think that was a mistake | 03:40 |
| CarlFK | mithro: not sure how travis passed it, cuz it broke here. I had to git checkout HEAD~ two times, now it builds | 04:16 |
| mithro | CarlFK: I think because the travis script does a "make firmware" before it does a "make gateware" | 04:17 |
| mithro | CarlFK: guess it might need to do a "make clean" between the two or something | 04:18 |
| CarlFK | mithro: is there a way for me to tell (visually, dmesg, whatever) that this loaded? PROG=fpgalink make load-gateware | 04:23 |
| mithro | CarlFK: not at this moment | 04:24 |
| mithro | CarlFK: I think you can check an LED on the FPGA - but I don't know which one | 04:24 |
| CarlFK | mithro: remember you had me add some extra parameters to dvsource-v4l2-other ? | 04:38 |
| mithro | CarlFK: nope! | 04:38 |
| CarlFK | it was before I recorded the 1 talk I have recorded. something about color space? | 04:39 |
| mithro | Nope! Check the logs? | 04:40 |

| CarlFK | neat - i didn't know there was a search | 04:44 |
| mithro | CarlFK: also why we should try and keep everything to the public channel as possible | 04:53 |
| mithro | CarlFK: looking at from what I can see in the logs the colorspace stuff got merged | 04:54 |

| seb_ | hi! | 11:14 |
| seb_ | i would like to understand what is realy done by the numato opsis card | 11:15 |
| seb_ | is it only mix and switch different input and output or is it able to encode stream too? | 11:16 |
| mithro | seb_: What you mean by "encode" the stream? | 11:24 |
| seb_ | i mean give us a compressed video file from uncompressed stream | 11:25 |
| seb_ | but i think i've my answer, it's more a passthru system | 11:26 |
| mithro | seb_: The USB / Ethernet output is mjpeg as you can't fit a raw 720p60 video through either of those interfaces | 11:27 |
| *** seb_ has left #timvideos | 11:27 | |
| mithro | _florent_: I'm around now if you have some time to chat | 11:27 |
| *** seb_ has joined #timvideos | 11:28 | |
| seb_ | ok, so the card encode in mjpeg the hdmi input | 11:29 |
| seb_ | can it deal with 4k videos? | 11:29 |
| seaLne | the hdmi inputs can't but the dp ones could | 11:37 |
| seaLne | (from what i've seen discussed before) | 11:38 |
| seb_ | and what about the outputs? | 11:38 |
| seaLne | same i think | 11:38 |
| seb_ | i'm a backer of the apertus axiom beta project (https://www.indiegogo.com/projects/axiom-beta-the-first-open-digital-cinema-camera#/story) | 11:39 |
| seb_ | and in their goal there is a 4k raw pc recording option using hdmi interface | 11:42 |
| mithro | seb_: We have not encoded mjpeg at 4k rates and even with mjpeg compression it would be impossible to ship 4k video out the USB / Ethernet interface - there isn't enough bandwidth | 11:42 |
| seb_ | ok | 11:42 |
| seaLne | ah | 11:43 |
| mithro | seb_: I'm actually hoping to finish a backer update which explains stuff around resolution a bit more | 11:43 |
| mithro | It's a complicated problem | 11:43 |
| mithro | seb_: You have to think about things like memory bandwidth too | 11:43 |
| seb_ | you both work around opensource hardware with FPGAs, maybe there can be interesting interaction between you ;) | 11:44 |
| seaLne | could theoretically it spit out webm instead of mpeg (not solution to resolution, would just save transcoding to a less restricted format) | 11:45 |
| seaLne | or in the future other formats | 11:45 |
| seaLne | not sure how much mjpeg is tied to hdmi | 11:46 |
| seb_ | and for direct ssd save through the expansion port? | 11:46 |
| mithro | seb_: I'm in the apertus IRC channel too :) | 11:48 |
| seb_ | mithro: you're working on the timvideo project? | 11:49 |
| mithro | seb_: I started the timvideos.us project :) | 11:50 |
| seb_ | ho, ok :) respect | 11:50 |
| seb_ | did you know the apertus project? | 11:51 |
| seb_ | do you already have contact with them? | 11:51 |
| mithro | seb_: yes, as I said I'm in the apertus IRC channel right now :) | 11:57 |
| seb_ | ok, cool :) | 12:01 |
| seb_ | did you participate to their crowdfunding campain? | 12:02 |
| mithro | seb_: No, sadly didn't have the funds for that | 12:05 |
| mithro | seb_: was very tempted though :) | 12:07 |
| mithro | seb_: I've already discussed with BlueCmd about an adapter board to make apertus expansion cards compatible with the Opsis | 12:08 |
| seb_ | :) | 12:08 |
| mithro | seb_: sadly, they didn't choose compatible pins - I guess in their case space was a premium | 12:09 |
| seb_ | if you can be compatible with their 4K RAW output with experimental HDMI formats that could be very cool | 12:11 |
| seb_ | for recording thought your expansion port maybe? | 12:12 |
| mithro | seb_: A purposed build expansion card which interfaces with the apertus would definitely be possible. As there are FPGAs on both sides of the interface you could do pretty much anyting. | 12:13 |
| seb_ | if you can just use common FPGA libs it can be interesting for future development | 12:14 |
| mithro | seb_: yeah, I think they are concentrating on "getting things done" at the moment | 12:14 |
| seb_ | yes :) they are a litle bit late on their planing :p | 12:15 |
| *** seb_ is now known as troisdsman | 12:20 | |
| mithro | troisdsman: but we will try and collaborate as much as possible :) | 12:20 |
| troisdsman | cool :) | 12:21 |
| mithro | troisdsman: of course we are a much smaller project then they are with substantially less funding | 12:22 |
| mithro | troisdsman: no big Hollywood names giving us money :( | 12:23 |
| mithro | troisdsman: The more successful the Opsis is, the more ability we'll have to do cool things in the future | 12:25 |
| troisdsman | yes :) | 12:28 |
| mithro | troisdsman: so please do get all your friends to back us :) | 12:28 |
| mithro | troisdsman: IE we'd love to develop a well tested, performant webm encoding core - but we just don't have the resources currently | 12:29 |
| troisdsman | for our utilisation your project is a little bit small :/ | 12:37 |
| troisdsman | we're working on a setup to record 4 flux in realtime (3 camera and one hdmi output) | 12:38 |
| troisdsman | is the numato opsis able to get 2 hdmi flux in realtime through usb? | 12:44 |
| mithro | flux? | 13:25 |
| troisdsman | stream sorry | 13:25 |
| mithro | troisdsman: Fitting 2 hdmi streams through USB2.0 isn't possible without significant lossy compression. We can probably get two streams out of the Gigabit Ethernet or another option would be via a PCI-Express adapter card connected to the GTP transceivers | 13:32 |
| troisdsman | ok | 13:32 |
| troisdsman | i'll talk of this option to my coworkers | 13:33 |
| troisdsman | thanks for your help! | 13:44 |
| troisdsman | bye | 13:44 |
