| mithro | CarlFK: once the gateware has been loaded, you need to reset the FPGA before you can load gateware again | 02:23 |
|---|---|---|
| CarlFK | mithro: I seem to have the atlys side working | 02:24 |
| mithro | CarlFK: what do you mean? | 02:24 |
| CarlFK | this works: mplayer tv:// -tv driver=v4l2:device=/dev/video1 ; I get a good display. | 02:25 |
| CarlFK | now trying to make this work ./dvsource-v4l2-other --device=/dev/video1 | 02:25 |
| CarlFK | this works fine: ./dvsource-v4l2-other -n ball | 02:26 |
| CarlFK | ./dvsource-v4l2-other --device=/dev/video1 - dvswitch shows no video, noisy audio on the meter and lots of this to stdout/error: | 02:27 |
| CarlFK | [dvvideo @ 0x202a800] could not find dv frame profile | 02:27 |
| CarlFK | WARN: Source 1using wrong sample rate | 02:27 |
| CarlFK | mithro: encoder: 1280x720 @ 0fps (0Mbps) from hdmi_in1 (q: 50) | 02:29 |
| CarlFK | 0fps is because nothing is ... polling it? (totally guessing how this works) | 02:29 |
| mithro | CarlFK: can you try dvsource-v4l2-other on your internal camera? | 02:29 |
| mithro | CarlFK: I think so, what happens when you connect mplayer back up? | 02:30 |
| CarlFK | --device=/dev/video0 (cam) same errors on dvswtich | 02:30 |
| CarlFK | mithro: mplayer .... encoder: 1280x720 @ 10fps (47Mbps) from hdmi_in1 (q: 50) | 02:32 |
| mithro | CarlFK: okay - so we need to figure out what is up with dvsource-v4l2-other | 02:32 |
| CarlFK | mithro: guessing the 1024x is wrong in: videoscale add-borders=1 ! video/x-raw,width=1024,height=768,pixel-aspect-ratio=\(fraction\)1/1 | 02:38 |

| mithro | CarlFK: that is just used to scale things to 4:3 resolution | 02:38 |
| CarlFK | this gives me 16:9 on dvswitch ./dvsource-v4l2-other -n ball | 02:39 |
| CarlFK | mithro: juser@dc10b:~/dvsource-v4l2-other$ grep device dvsource-v4l2-other.py | 03:01 |

| CarlFK | --device=/dev/video1 | 03:02 |
| CarlFK | device is never used! | 03:02 |
| mithro | I'll look at it in an hour or two | 03:04 |
| CarlFK | # Read the v4l2 input and decode it if it's a mjpeg input | 03:04 |
| CarlFK | "v4l2src ! " + | 03:04 |
| mithro | Hrm.... | 03:04 |
| CarlFK | fixed. gst-launch-1.0 -v v4l2src device=/dev/video1 ! decodebin | 03:06 |
| CarlFK | but dvswitch still not being good | 03:06 |
| CarlFK | here is a patch :) "v4l2src device=%s ! " % args.device + | 03:07 |
| CarlFK | mithro: do you know about vivi? sudo modprobe vivi; dmesg; [29251.673777] vivi-000: V4L2 device registered as video2 | 03:11 |
| CarlFK | [29251.673783] Video Technology Magazine Virtual Video Capture Board ver 0.8.1 successfully loaded. | 03:11 |
| CarlFK | mplayer tv:// -tv driver=v4l2:device=/dev/video2 | 03:11 |
| CarlFK | see moving color bars and some stats | 03:12 |
| mithro | Nope. I have used v4l2loopback though. | 03:13 |
| mithro | Just on my phone now. | 03:16 |
| CarlFK | mithro: one less thing to worry about: using dev/video1 now encoder: 1280x720 @ 10fps (47Mbps) from hdmi_in1 (q: 50) | 03:22 |
| *** sb0 has joined #timvideos | 05:35 | |
| CarlFK | got something working. added videoconvert and format=I420 | 06:11 |
| CarlFK | arg. I have dvswitch workign with static. now trying to get hdmi input and the laptop does not see a display device like it did last night. | 07:10 |
| mithro | CarlFK: unplug and replug it? | 07:26 |
| CarlFK | mithro: no luck | 07:32 |
| mithro | CarlFK: what is the laptop and how is it connected? and what are you using to detect the display? | 07:33 |
| mithro | Well, I need to head to bed, which means CarlFK should probably be well asleep too | 07:46 |
| CarlFK | still here... sec... | 07:49 |
| CarlFK | HDMI1 connected 1280x720+0+0 (normal left inverted right x axis y axis) 200mm x 112mm | 07:50 |
| CarlFK | not kidding, that happened when I got a dhcp lease. | 07:50 |
| CarlFK | I have been plugging and unplugging and moving it around trying to find a live cat5 | 07:51 |
| CarlFK | got an IP, plugged in hdmi, now it sees it | 07:51 |
| mithro | can you turn on HPD debugging? | 07:53 |

| CarlFK | echo 6 > /sys/module/drm/parameters/debug ... then what? | 07:55 |
| CarlFK | http://paste.ubuntu.com/12228930/ dmesg | 08:02 |
| tpb | Title: Ubuntu Pastebin (at paste.ubuntu.com) | 08:02 |
| mithro | CarlFK: that is useful output when the laptop isn't seeing the device | 08:09 |
| CarlFK | k | 08:09 |
| mithro | but I really must go to bed myself | 08:10 |
| CarlFK | k | 08:11 |
| CarlFK | good night - I'll get back to this in about 8 hours | 08:11 |

| _florent_ | mithro: yes raspberry pi was ok | 21:21 |
| mithro | _florent_: awesome! | 21:30 |
| mithro | _florent_: I wanted to ask you about the best way to add "mnemonic" port names to the misoc firmware | 21:30 |
| mithro | _florent_: What is the best way to tag the ports with their "jumper name" and "a text description" that we can show in the firmware? I assume we can just add extra info to the platforms file which gets written to a header somewhere? | 22:16 |
