| xfxf | mithro: i'm guessing you recorded the video in this talk, i can see a disassembled opsis at the start? https://news.ycombinator.com/item?id=12528206 | 03:10 |

| xfxf | also the 15 fps thing was a firmware bug i had ages back, i thought that was fixed? | 03:10 |
| mithro | xfxf: That was running the shipping firmware, didn't have time to flash with something newer | 03:37 |
| xfxf | ah, that explains the 15fps thing | 03:39 |
| xfxf | also,the lack of artifacts - the shipping firmwares doesn't suffer from that? | 03:40 |
| xfxf | if so, hopefully that makes tracking down the actual cause easier | 03:41 |
| mithro | xfxf: It does | 03:41 |
| mithro | xfxf: It does suffer from the artifacts, if I had multiple outputs enabled it was worse | 03:42 |
| xfxf | hmm, I'm sure with the firmware we used at pycon, even two inputs, encoder, both outputs off was way worse than what I see in that vid | 03:47 |
| xfxf | but I'd need to check | 03:47 |

| xfxf | oh hang, i was testing it with one output enabled too. that'd explain the difference | 04:08 |
| CarlFK | start of what? | 04:09 |

| xfxf | CarlFK: click on the actual story, it's in there? | 05:56 |
| CarlFK | mithro: neat. | 05:56 |
| CarlFK | xfxf: heck if I know | 05:56 |
| CarlFK | im sure if I follow enough links I will come to something ;) | 05:57 |
| mithro | CarlFK: You can get yourself a 10G network card | 05:57 |
| xfxf | mithro: have you actually used that switch? | 05:57 |
| xfxf | mithro: microtik gear can be.... interesting | 05:57 |
| mithro | Nope, but it has evil_steve recommendation | 05:57 |
| xfxf | he's using microtik in production at universities? that genuinely surprises me | 05:57 |
| mithro | xfxf: Probably not, but for the price point he said it was probably an okay buy | 05:58 |
| CarlFK | do we need 10G? (or is this for my 2017 UN thing?) | 05:59 |
| xfxf | i've decided against buying any 10G gear now, i'm going to experiment with LACP bonded gigabit first | 06:00 |
| xfxf | i doubt i'd ever need more than 2-3G, and it's always going to/from seperate machines, so mac based lacp should in theory be perfectly fine | 06:00 |
| xfxf | CarlFK: i think he's talking if we want more than 2-3 uncompressed audio/video ingests | 06:01 |
| CarlFK | ah, yeah, I don't need that any time soon. I hope. | 06:02 |
| mithro | xfxf: When we get Opsis Ethernet working, that is going to be ~800Mbps | 06:04 |
| xfxf | mithro: why would uncompressed video over the Opsis ethernet be more than now? | 06:04 |
| mithro | xfxf: I'm unsure why the current value is so low | 06:04 |
| CarlFK | mithro: what makes you think it will be ~800Mbps? | 06:05 |
| xfxf | mithro: isn't the current rate higher than what it could be, due to us doing full 24-bit color depth or whatever? | 06:06 |
| mithro | CarlFK: actual calculations | 06:06 |
| CarlFK | mithro: show your work ;) | 06:08 |
| CarlFK | except I want to compare it to what gs is doing, and that's probably not something I should try | 06:09 |

| CarlFK | mithro: do you expect the Opsis to be able to connect to vocto core, or would we run a gst pipeline to hook the two together? | 06:33 |
| mithro | CarlFK: Probably a pipeline unless there are some changes to voctocore to support it | 06:34 |
| mithro | The pipeline should be pretty simple though | 06:37 |
| CarlFK | mithro: that also means the pipeline can decompress | 07:04 |
| mithro | CarlFK: The frames from the Opsis are uncompressed | 07:04 |
| CarlFK | mithro: I am guessing the mjpeg compression could be applied | 07:06 |
| mithro | Sure I guess | 07:06 |
| mithro | We should be able to just do two streams at 30fps | 07:06 |
| CarlFK | mithro: like one for each input? | 07:07 |
| mithro | CarlFK: yes | 07:07 |
| CarlFK | neat | 07:07 |
| mithro | Oh - that is probably the reason - 30fps verse 60fps | 07:08 |
