mithroCarlFK: hrm?04:42
CarlFK dvsource-v4l2-other -d /dev/video1 -c="image/jpeg,width=1280,height=720" -s ntsc -a 16:9'04:42
mithroCarlFK: ahh - I guess we should write that down somewhere or add a command line argument to dvsource-v4l2-other to do that04:43
CarlFKI have it in dvsmon now, so im set ;)04:44
CarlFKI need to get going04:44

CarlFKbut we may have trouble feeding them vga :p05:15
CarlFKno streaming05:15
mithroCarlFK: I'm going a talk about the HDMI2USB and misoc/migen firmware at SyPy tonight05:21
seaLnesounds interesting, is it being recorded?05:29
mithroseaLne: I'm going to give it a go using the HDMI2USB :P05:31
mithroseaLne: It'll probably fail miserably :)05:31
mithroseaLne: I haven't tested things very well and still writing my talk :)05:31
seaLnegood luck05:32

seaLneCarlFK: so you are still using dvswitch but using the atlys instead of a twinpact?08:10
CarlFKseaLne: yep08:13
CarlFKstill ntsc, but it is crisp compared to the vga (guessing because vga is analog08:16

CarlFKmithro: tumbleweed's ibm and my hp laptop is having issues08:44
CarlFKoh wait.. we got tumbleweed's resolved.08:44
CarlFKmy hp shows connected to a display device, but status shows input 0x008:45
*** tija has joined #timvideos09:06
tumbleweedCarlFK: we had to use input 109:09
tumbleweedmy presenter is walking back and forth, with his back always to the camera :P09:09
CarlFKmy white balance is off09:10
tijamithro: Everything was fine till you started playing with serial interface.09:14
mithrotija: ha09:33
mithrotija: My computer dropped off wireless09:33
mithrotija: was unrelated to the HDMI2USB09:33
tijamithro: okay. Takeaway from the talk- "mithro is a very practical man"09:34
mithrotija: You should know that :-P09:36
mithrotija: you saw right?10:15
mithroCarlFK: things exploded yet?10:29
tumbleweedthey're refusing to explode :(10:30
mithroCarlFK / tumbleweed ->
tumbleweedlol, at the idea of watching youtube on this network10:32
mithrotumbleweed: its HD too! :-P10:33

tumbleweedurgh CarlFK. Just picked up the headphones on the camera and found I've been clipping for a while12:01
tumbleweedeven though the dvswitch meter was never going above -1212:01
* tumbleweed is more used to a streaming audience that reports these things :(12:03
tumbleweed(and a separate audio guy :P )12:03

_florent_mithro: where you using HDMI2USB to record your talk?13:15
mithro_florent_: yes13:23
mithro_florent_: okay - I have a Chrome book here which the HDMI2USB doesn't detect the video from13:29
mithro_florent_: the Chromebook appears to be sending a signal...13:29
mithro_florent_: oh interesting...13:31
mithro_florent_: the Chromebook appears to have been sending 60Hz signal despite the video_mode being set to 50Hz13:32
mithro_florent_: can we get the vsync/hsync in the status output?13:33
_florent_I don't think so13:43
_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 working13:52
mithro_florent_: obviously something in changing the video_mode causes the something to lock onto the video signal?13:55
tpbTitle: HDMI2USB-misoc-firmware/processor.c at master · timvideos/HDMI2USB-misoc-firmware · GitHub (at
_florent_you should try to figure out which line of this function make it working13:57
mithro_florent_: want to take bets which one? :P13:57
_florent_hdmi_inx_disable/edid_set_mode/hdmi_inx_init_video probably13:59
tumbleweedhrm, just had an ubuntu laptop that wouldn't mirror to the hdmi2usb, because the internal display couldn't do 1028x72014:01
tumbleweedall sorts of resolutions, but not that one14:01
tumbleweedand another machine with the same problem14:04
tumbleweedlightning talks ++14:05
mithrotumbleweed: I've got a mostly working patch which will let you add custom edid values14:09
CarlFK_florent_: JayChromebook is still14:16
CarlFK_florent_: Jay's Chromebook is still giving me issues.14:16
CarlFKsolution: video_mode 9 (or hit the reseet button)14:16
_florent_say issue than mithro then14:17
mithro_florent_: Jinx!14:17
tumbleweedmithro: so, my laptop also didn't have that mode, but xrandr --output eDP1 --mode 1280x960 --output HDMI1 --auto --same-as eDP1 worked14:23
tumbleweedmaybe we should be telling people to do that14:23
tumbleweedrather than try to GUI14:23
tumbleweedoh, I might have been cropping a bit :/14:24
mithrotumbleweed: yeah - you would have been cropping a bit14:24
* tumbleweed wonders what the best is. transforms?14:25
mithrotumbleweed: I was thinking about video scaling / transforms a bit earlier14:28
mithrookay - it is one of these lines14:28
tpbTitle: Pastebin | IRCCloud (at
tumbleweed--fb 1280x720  think14:30
tumbleweedI was thinking an xrandr transform on the laptop display - keep the output pretty14:31
tumbleweed"xrandr --output eDP1 --auto --scale-from 1280x720 --output HDMI1 --auto --same-as eDP1" looks good14:32
mithro_florent_: Its the following line -> hdmi_in1_init_video(m->h_active, m->v_active);14:36
mithrowe really need to add some shortcuts to the command line interface :P14:37
mithroor 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 SyPy14:38
mithroseeing as shenki has been really slack :P14:39
mithro_florent_: My guess is the PLL reset in hdmi_in1.c on line 10114:41
_florent_yes probably14:42
*** rohitksingh has joined #timvideos14:46
mithrohey rohitksingh14:47
mithro_florent_: so I added commands to turn hdmi_in1_debug on14:55
rohitksinghmithro: hi! Just arrived home and saw github notification14:55
rohitksinghmithro: 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: ok14:58
mithro_florent_: and I notice nothing happens until I for EDID to be read from my laptop14:59
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 pins15:04
*** rohitksingh1 has joined #timvideos15:05
*** rohitksingh has quit IRC15:06
mithroI'm using the Atlys at the moment15:09
mithroWell actually in walking home at  moment as it is 1am15:10
mithroUntil we get the CDC serial port working again, the Opsis is slightly hard to use.15:13
*** CarlFK has quit IRC15:14
_florent_yes, too bad it does not have another uart...15:15
mithroWell, I could do the UART totally on the Cypress15:16
mithroI already have that working15:16
_florent_yes, that would fine no?15:17
_florent_at least for now?15:17
mithroYeah, but I actually have to do it :-)15:18
mithroI think we want the CDC functionality even on the Atlys so we only need one USB cable15:19
mithroSomething for the weekend15:20
mithro_florent_: any chance you could see if you can replicate my DDR issue? That's preventing me from doing much with the Opsis too15:22
_florent_yes sorry, I'll try to look at that15:22
mithroI'm stuck in a lift15:29
mithroWell, I get to spend another 20 minutes in this lift and my phone is going flat :-(15:40
rohitksingh1mithro: power loss or malfunctioning lift?15:58
rohitksingh1got out?15:59
mithroPower loss then the lift didn't reboot properly it seems.15:59
mithroStill in here15:59
mithroThe technician has arrived though16:00
rohitksingh1:o thats long!16:00
mithroOr at least someone claiming to be a technician..16:00
rohitksingh1oh! still good to know atleast someone is there!16:01
mithroThe lift is doing strange things now. So I assume he is doing stuff...16:02
mithroIf I disappear, its because my phone died rather then plumbiting to my death hopefully.16:02
rohitksingh1haha okay :D16:04
mithroI'm free!16:08
