| CarlFK | mithro: I think you should skip the find-.py and work on flashing | 04:38 |
| mithro | CarlFK: the find-.py thing is needed for reliable flashing | 04:39 |
| CarlFK | hmm | 04:39 |
| mithro | CarlFK: so how did things go? | 04:40 |
| mithro | CarlFK: or are you yet to go? | 04:40 |
| CarlFK | show starts in 3 hours | 04:40 |
| mithro | CarlFK: okay | 04:40 |
| CarlFK | rooms are setup. getting the Atly's up was .... I had to dig up the -c mjpeg options for dvsourc-v4l-ohter | 04:41 |
| mithro | CarlFK: hrm? | 04:42 |
| CarlFK | dvsource-v4l2-other -d /dev/video1 -c="image/jpeg,width=1280,height=720" -s ntsc -a 16:9' | 04:42 |
| mithro | CarlFK: ahh - I guess we should write that down somewhere or add a command line argument to dvsource-v4l2-other to do that | 04:43 |
| CarlFK | I have it in dvsmon now, so im set ;) | 04:44 |
| CarlFK | I need to get going | 04:44 |
| mithro | CarlFK: yes but that doesn't help anyone else | 04:44 |

| mithro | CarlFK: are you using the twinpacts are fall backs? | 05:14 |
| CarlFK | not a chance | 05:14 |
| CarlFK | er | 05:14 |
| CarlFK | no streaming. twinpacts are hooked up | 05:15 |
| CarlFK | but we may have trouble feeding them vga :p | 05:15 |
| CarlFK | no streaming | 05:15 |
| mithro | CarlFK: I'm going a talk about the HDMI2USB and misoc/migen firmware at SyPy tonight | 05:21 |
| seaLne | sounds interesting, is it being recorded? | 05:29 |
| mithro | seaLne: I'm going to give it a go using the HDMI2USB :P | 05:31 |
| seaLne | cool | 05:31 |
| mithro | seaLne: It'll probably fail miserably :) | 05:31 |
| mithro | seaLne: I haven't tested things very well and still writing my talk :) | 05:31 |

| CarlFK | seaLne: yep | 08:13 |
| CarlFK | still ntsc, but it is crisp compared to the vga (guessing because vga is analog | 08:16 |

| tija | mithro: Everything was fine till you started playing with serial interface. | 09:14 |
| mithro | tija: ha | 09:33 |
| mithro | tija: My computer dropped off wireless | 09:33 |
| mithro | tija: was unrelated to the HDMI2USB | 09:33 |
| tija | mithro: okay. Takeaway from the talk- "mithro is a very practical man" | 09:34 |
| mithro | tija: You should know that :-P | 09:36 |
| mithro | tija: you saw https://www.youtube.com/watch?v=eR4i-XJDGCM right? | 10:15 |

| mithro | CarlFK / tumbleweed -> https://www.youtube.com/watch?v=Bxkz6XSiB3Y | 10:31 |
| tumbleweed | lol, at the idea of watching youtube on this network | 10:32 |
| mithro | tumbleweed: its HD too! :-P | 10:33 |

| tumbleweed | awww | 11:51 |
| tumbleweed | why? | 11:51 |
| tumbleweed | urgh CarlFK. Just picked up the headphones on the camera and found I've been clipping for a while | 12:01 |
| tumbleweed | even though the dvswitch meter was never going above -12 | 12:01 |

| _florent_ | mithro: where you using HDMI2USB to record your talk? | 13:15 |
| mithro | _florent_: yes | 13:23 |
| _florent_ | cool | 13:24 |
| mithro | _florent_: okay - I have a Chrome book here which the HDMI2USB doesn't detect the video from | 13:29 |
| mithro | _florent_: the Chromebook appears to be sending a signal... | 13:29 |
| _florent_ | ah | 13:31 |
| mithro | _florent_: oh interesting... | 13:31 |
| mithro | _florent_: the Chromebook appears to have been sending 60Hz signal despite the video_mode being set to 50Hz | 13:32 |
| mithro | _florent_: can we get the vsync/hsync in the status output? | 13:33 |
| _florent_ | I don't think so | 13:43 |
| _florent_ | and if you set the video mode to 60Hz, is it working? | 13:44 |
| mithro | _florent_: it seems doing a "video_mode 9" or "video_mode 10" causes it to start working | 13:52 |
| _florent_ | strange | 13:52 |
| mithro | _florent_: obviously something in changing the video_mode causes the something to lock onto the video signal? | 13:55 |
| _florent_ | https://github.com/timvideos/HDMI2USB-misoc-firmware/blob/master/firmware/lm32/processor.c#L364 | 13:56 |
| tpb | Title: HDMI2USB-misoc-firmware/processor.c at master · timvideos/HDMI2USB-misoc-firmware · GitHub (at github.com) | 13:56 |
| _florent_ | you should try to figure out which line of this function make it working | 13:57 |
| mithro | _florent_: want to take bets which one? :P | 13:57 |
| _florent_ | hdmi_inx_disable/edid_set_mode/hdmi_inx_init_video probably | 13:59 |
| tumbleweed | hrm, just had an ubuntu laptop that wouldn't mirror to the hdmi2usb, because the internal display couldn't do 1028x720 | 14:01 |
| tumbleweed | all sorts of resolutions, but not that one | 14:01 |
| tumbleweed | and another machine with the same problem | 14:04 |
| tumbleweed | lightning talks ++ | 14:05 |
| mithro | tumbleweed: I've got a mostly working patch which will let you add custom edid values | 14:09 |
| CarlFK | _florent_: JayChromebook is still | 14:16 |
| CarlFK | er | 14:16 |
| CarlFK | _florent_: Jay's Chromebook is still giving me issues. | 14:16 |
| CarlFK | solution: video_mode 9 (or hit the reseet button) | 14:16 |
| _florent_ | say issue than mithro then | 14:17 |
| mithro | _florent_: Jinx! | 14:17 |
| tumbleweed | mithro: so, my laptop also didn't have that mode, but xrandr --output eDP1 --mode 1280x960 --output HDMI1 --auto --same-as eDP1 worked | 14:23 |
| tumbleweed | maybe we should be telling people to do that | 14:23 |
| tumbleweed | rather than try to GUI | 14:23 |
| tumbleweed | oh, I might have been cropping a bit :/ | 14:24 |
| mithro | tumbleweed: yeah - you would have been cropping a bit | 14:24 |
| * tumbleweed wonders what the best is. transforms? | 14:25 | |
| mithro | tumbleweed: I was thinking about video scaling / transforms a bit earlier | 14:28 |
| mithro | okay - it is one of these lines | 14:28 |
| mithro | https://www.irccloud.com/pastebin/w6BR3sz3/ | 14:29 |
| tpb | Title: Pastebin | IRCCloud (at www.irccloud.com) | 14:29 |
| tumbleweed | --fb 1280x720 think | 14:30 |
| tumbleweed | I was thinking an xrandr transform on the laptop display - keep the output pretty | 14:31 |
| tumbleweed | "xrandr --output eDP1 --auto --scale-from 1280x720 --output HDMI1 --auto --same-as eDP1" looks good | 14:32 |
| mithro | _florent_: Its the following line -> hdmi_in1_init_video(m->h_active, m->v_active); | 14:36 |
| mithro | we really need to add some shortcuts to the command line interface :P | 14:37 |
| mithro | or tab completion.... | 14:37 |
| _florent_ | or python script to control the board... :) | 14:38 |
| mithro | _florent_: yeah - I might have found someone to do that at SyPy | 14:38 |
| mithro | seeing as shenki has been really slack :P | 14:39 |
| mithro | _florent_: My guess is the PLL reset in hdmi_in1.c on line 101 | 14:41 |
| _florent_ | yes probably | 14:42 |
| *** rohitksingh has joined #timvideos | 14:46 | |
| mithro | hey rohitksingh | 14:47 |
| mithro | _florent_: so I added commands to turn hdmi_in1_debug on | 14:55 |
| rohitksingh | mithro: hi! Just arrived home and saw github notification | 14:55 |
| rohitksingh | mithro: didn't get much time this week...but I think I'm better in misoc now! would need help in some areas though...I've holiday tomorrow, so I'm planning for all nighter tonight working on porting the code! | 14:58 |
| _florent_ | mithro: ok | 14:58 |
| mithro | _florent_: and I notice nothing happens until I for EDID to be read from my laptop | 14:59 |
| mithro | _florent_: what does the hdmi_in1_edid_hpd_notif_read() function do? | 15:01 |
| mithro | _florent_: I assume it is suppose to go true when the EDID has been read? | 15:03 |
| _florent_ | are you using atlys of opsis? | 15:04 |
| _florent_ | atlys does not have hdp pins | 15:04 |
| *** rohitksingh1 has joined #timvideos | 15:05 | |
| *** rohitksingh has quit IRC | 15:06 | |
| mithro | I'm using the Atlys at the moment | 15:09 |
| mithro | Well actually in walking home at moment as it is 1am | 15:10 |
| mithro | Until we get the CDC serial port working again, the Opsis is slightly hard to use. | 15:13 |
| *** CarlFK has quit IRC | 15:14 | |
| _florent_ | yes, too bad it does not have another uart... | 15:15 |
| mithro | Well, I could do the UART totally on the Cypress | 15:16 |
| mithro | I already have that working | 15:16 |
| _florent_ | yes, that would fine no? | 15:17 |
| _florent_ | at least for now? | 15:17 |
| mithro | Yeah, but I actually have to do it :-) | 15:18 |
| mithro | I think we want the CDC functionality even on the Atlys so we only need one USB cable | 15:19 |
| mithro | Something for the weekend | 15:20 |
| mithro | _florent_: any chance you could see if you can replicate my DDR issue? That's preventing me from doing much with the Opsis too | 15:22 |
| _florent_ | yes sorry, I'll try to look at that | 15:22 |
| mithro | I'm stuck in a lift | 15:29 |
| mithro | Yay | 15:29 |
| mithro | Well, I get to spend another 20 minutes in this lift and my phone is going flat :-( | 15:40 |
| rohitksingh1 | mithro: power loss or malfunctioning lift? | 15:58 |
| rohitksingh1 | got out? | 15:59 |
| mithro | Power loss then the lift didn't reboot properly it seems. | 15:59 |
| mithro | Still in here | 15:59 |
| mithro | The technician has arrived though | 16:00 |
| rohitksingh1 | :o thats long! | 16:00 |
| mithro | Or at least someone claiming to be a technician.. | 16:00 |
| rohitksingh1 | oh! still good to know atleast someone is there! | 16:01 |
| mithro | The lift is doing strange things now. So I assume he is doing stuff... | 16:02 |
| mithro | If I disappear, its because my phone died rather then plumbiting to my death hopefully. | 16:02 |
| rohitksingh1 | haha okay :D | 16:04 |
| mithro | I'm free! | 16:08 |
| rohitksingh1 | finally! | 16:13 |
