| CarlFK | mithro: I am at ps1 sitting next to the guy with the odd chromebook - he will be here for another hour or two - any chance you have something soon? (I am assuming you are hacking on the firmware?) | 00:31 |
| mithro | CarlFK: I don't think I'll have something soon - but unsure, lets see how it goes | 00:36 |
| mithro | CarlFK: I have a small job for you - Could you write up a little Python UI for controlling the HDMI2USB firmware? Something which kind of looks like this -> | 00:37 |
| CarlFK | mithro: that is going to be well below #3 on my priority list #1 and #2 are finish processing videos from PyOhio and PyGotham (you can see status in my new page, which I needed to do to answer the question "whats the status?" | 00:40 |

| CarlFK | before you go.. | 03:46 |
| CarlFK | It just occurred to me - is it worth comparing the old firmware to the new in regards to the EDID or device detection problem? | 03:47 |

| _florent_ | I've added EDID debug counters | 11:02 |
| _florent_ | debug edid and debug edid_reset | 11:02 |
| _florent_ | it would be interesting to test that with your video source that is not working correctly | 11:02 |
| _florent_ | it seems I've found a video source here that is not working, so I'll be able to investigate with it, but that's maybe not the same issue you have | 11:03 |

| *** sb0_ has joined #timvideos | 14:16 | |
| _florent_ | yes, install from migen was missing I think, and now there is liteeth dependency. | 14:23 |
| CarlFK | _florent_: thanks - will test in about an hour | 14:27 |
| mithro | _florent_: I'm going to set up a virtualenv to install to | 14:41 |
| mithro | _florent_: btw - I actually think having major cores in their own repositories is a good idea. | 14:44 |
| mithro | tumbleweed: where did we get with packaging the vizzini / exar-uart-driver driver? | 14:45 |
| mithro | CarlFK: when you get a moment, can you take a look at the pull request that _florent_ merged? I'd still like you to check the numbers | 14:46 |
| *** rohitksingh has quit IRC | 14:47 | |
| tumbleweed | mithro: well, it's in your fpga-support PPA | 14:49 |
| mithro | tumbleweed: great! | 14:50 |
| mithro | tumbleweed: can we make sure that the PPA has packages for the latest LTS (trusty) and the latest Ubuntu release (which is ??) | 14:50 |
| tumbleweed | I think you can binary copy all of them forward to vivid | 14:51 |
| tumbleweed | maybe not the gstreamer one, but likely even that | 14:51 |
| mithro | tumbleweed: I forget how the PPAs work, we can't just upload the same package with trusty and latest? Do we need to have separate PPAs? | 14:52 |
| tumbleweed | you can copy them without even re-uploading | 14:53 |
| * tumbleweed does that | 14:53 | |
| mithro | tumbleweed: I'm afraid that I don't quite understand | 14:58 |
| tumbleweed | the same source+binary package can be published for multiple releases | 15:00 |
| tumbleweed | this is how ubuntu starts a new release cycle, everything doesn't get re-built | 15:00 |
| CarlFK | mithro: what PR, and what numbers? | 15:01 |
| mithro | CarlFK: see last discussion night | 15:01 |
| tumbleweed | in this case, I don't think any of these packages *needed* to be re-built, so I just copied the binaries forward | 15:01 |
| tumbleweed | the one exception may be the gst plugin, if that doesn't work, we should re-upload it for vivid | 15:02 |
| *** rohitksingh has joined #timvideos | 15:04 | |
| mithro | tumbleweed: can you explain what you did to "copy the binaries forward" ? | 15:22 |
| tumbleweed | click on the copy link on the +packages page | 15:36 |
| tumbleweed | then select existing binaries :) | 15:36 |

| andi_m | mithro: does the Opsis board support hdmi ports support higher resolutions than 720p? | 18:52 |
| TobiX | Hi! | 18:53 |
| andi_m | mithro: actually I was just forwording the question from TobiX | 18:54 |
| CarlFK | andi_m: i don't really know what I am talking about.. but I think the answer is: board: yes. encoder: no. | 18:55 |
| TobiX | mithro: What andi_m is asking. The CrowdSupply page says: "resolution: 720p or 1024 x 768" for the HDMI ports - Is this a hard limitation, so only the DisplayPort ports can handle higher resolutions? | 18:55 |
| *** sb0_ has joined #timvideos | 18:58 | |
| CarlFK | 720p 30fps is pushing the current encoder/usb, so higher resolutions means dropping the quality / fps | 18:59 |
| *** sb0_ has quit IRC | 19:00 | |
| mithro | Well technically they can do 1080i but I think interlaced formats are evil | 19:00 |
| TobiX | mithro: Well, obviously ;) | 19:01 |
| *** sb0__ has quit IRC | 19:02 | |
| mithro | TobiX, andi_m: 720p60 is the limit of the pins the HDMI ports are connected to | 19:02 |
| TobiX | Next you say you want to capture 1080i30... Well, if you want to capture "current-gen" video game console footage, that will probably enough :-P | 19:03 |
| TobiX | mithro: But I could technically use the DisplayPort pins? | 19:04 |
| mithro | Yes, the DisplayPort goes up to ~4k (in theory) but you'll then have issues about what to do with that much content. | 19:07 |
| TobiX | Gigabit it away? | 19:12 |
| TobiX | Holy crap, I didn't realize how expensive all those Epiphan devices were: http://www.epiphan.com/products/ ... | 19:16 |

| mithro | 4k is ~12Gbit/s doesn't really fit in a gigabit :-) | 19:25 |
| TobiX | mithro: Damnit :) | 19:25 |
| TobiX | mithro: I didn't do the math, sorry :) | 19:26 |
| mithro | Getting a 12x compression isn't impossible - but you would be hitting limits of all parts of the platform (FPGA space, memory speed, etc) extremely hard. | 19:34 |

| CarlFK | mithro: you asked about it a while ago. | 19:54 |
| CarlFK | mithro: I am still not sure either of us would make good use of them. I am shopping for hdmi cables and adapters | 19:54 |
| andi_m | TobiX: didn't you have one of this ephiphan broadcaster in colone? | 20:38 |
| TobiX | andi_m: Well, yes. We used them for older CCC events (I don't know how the current setup is) | 20:42 |
| TobiX | They're kinda crappy... They keep building up delays over time. We somewhere have a list of settings on which the drifting is minimal (I think MJPEG or something) | 20:45 |
| *** rohitksingh has quit IRC | 20:48 | |

| _florent_ | can you try with a source that is working fine | 22:18 |
| _florent_ | (and to debug edid_reset before) | 22:18 |
| _florent_ | do | 22:18 |
| CarlFK | _florent_: heh.. I don't have a reliable source right now | 22:23 |
| _florent_ | ok i'm going to investigate on that tomorrow | 22:25 |
