| puck_ | CarlFK[m], okay, using https://github.com/CarlFK/veyepar/wiki/System-Stack#i-just-want-to-see-if-my-device-works-with-voctomix I get the encoder as expected | 05:15 |

| puck_ | I started to work out a basic gst-launch-1.0 command however now I get the Input/output error on both my laptop and my Voctomix box | 05:16 |
| CarlFK | puck_: yay. progress. and about the same experience I have | 05:18 |
| CarlFK | the IO error ... my guess is you connected to the console before the video device. which trips a bug | 05:19 |
| puck_ | Heh. I was able to strip down the pipeline that voctomix-ingest spits out to replicate it on my laptop as well. | 05:19 |
| puck_ | defined "console" in this case? | 05:19 |
| puck_ | Connecting via /dev/ttyACM0? | 05:20 |
| puck_ | I guess "yes", as I just disconnecting from the serial console, rebooted the board and now it works | 05:21 |
| CarlFK | yeah that | 05:21 |
| CarlFK | if you rmmod uvcvideo; modprobe uvcvideo that fixes it | 05:22 |
| CarlFK | im trying to find the bug report. which I can never find... | 05:22 |
| puck_ | :) | 05:22 |
| puck_ | Heh, I just plugged it into my laptop to try and again and wondering why it was broken again. Of course, I had tio running there... | 05:23 |
| puck_ | Interestingly this time I just had to exit the serial terminal and it started working again | 05:23 |
| CarlFK | yeah, it is a weird one | 05:25 |
| puck_ | Okay "decodebin" in the pipeline doesn't work, it needs to be "jpegdec" | 05:25 |
| puck_ | This pipeline works: v4l2src device=$device ! jpegdec ! fpsdisplaysink sync=false | 05:26 |
| puck_ | Where $device is the device | 05:26 |

| CarlFK | oh neat - thanks for the simple gst test | 05:31 |
| puck_ | That bug about the serial console feels like something that belongs on a getting started page, especially since tio doesn't close. ;) | 05:32 |
| puck_ | Incidentally, I had to use `tio -m INLCRNL /dev/ttyACM0` to get newlines to behave correctly. | 05:32 |
| CarlFK | huh. never had that problem | 05:34 |
| puck_ | I was getting a new line, but not a carriage return. | 05:35 |
| CarlFK | If you try to pipe commands to /dev/ttyACM0. (or type too fast, or paste a line into tio...) you will overflow some buffer... | 05:36 |
| puck_ | heh, oops | 05:36 |

| tpb | Title: serial port drops characters · Issue #13 · timvideos/HDMI2USB-fx2-firmware · GitHub (at github.com) | 05:36 |
| puck_ | Actually, yeah, I was getting that | 05:37 |
| CarlFK | cstream -b 1 -t 50 | 05:39 |
| CarlFK | that will throttle stdio | 05:39 |
| puck_ | heh | 05:40 |
| puck_ | so cstream -b 1 -t 50 | tio ... ? | 05:44 |
| puck_ | I've not used it before | 05:44 |
| puck_ | Ah, found your example command on the bug. | 06:41 |
| puck_ | Another option is Expect, as that can slow itself down for output | 06:41 |
