| tsglove | Good morning/evening/afternoon! o/ | 13:30 |
|---|---|---|
| tsglove | Happy to be here! =) | 13:30 |
| tsglove | Just saw for the first time the Numato board, which took me to hdmi2usb.tv, which took me to TimVideos.us, which took me here! | 13:31 |
| tsglove | Can one of the Numato Opsis boards be bought right now? | 13:31 |
| CarlFK | tsglove: hi | 13:49 |
| tsglove | o/ CarlFK ! | 13:49 |
| tsglove | Still reading up on the boards and the project. | 13:49 |
| tsglove | Looks awesome. | 13:49 |
| tsglove | I have done two small events in the past, and I used the Livestream service, jointly with their "Livestream Broadcaster Pro" box.... | 13:50 |
| tsglove | Yet, being part of the hacker mindset... this looks much more fun. And fun has a lot of weight. | 13:50 |
| tsglove | Is there a way now to use the Numato Opsis board, and have it stream off to a web server? | 13:50 |
| CarlFK | https://www.crowdsupply.com/numato-lab/opsis - not sure if you can buy it | 13:50 |
| tpb | Title: Numato Opsis: FPGA-based Open Video Platform | Crowd Supply (at www.crowdsupply.com) | 13:50 |
| tsglove | I know there are various "pieces" to this setup... like, | 13:51 |
| tsglove | I *think* it is for sale now... I think in the Numato website itself... checking. | 13:51 |

| CarlFK | icecast is a streaming server | 13:55 |
| CarlFK | personally, I use youube (but haven't collected the scripts for that yet) | 13:55 |
| tsglove | icecast? searching for it now | 14:08 |
| tsglove | What I don't like about YouTube is that I don't have control over the advertisements displayed on the page. | 14:08 |
| tsglove | And I tried with Facebook Live this past event, and the problem was that Facebook "recognized" music the DJ was playing, determined I didn't have the license for said music, and cut the stream. | 14:09 |
| tsglove | So... yeah. | 14:09 |
| tsglove | CarlFK, I am reading the Icecast page now... yet a little bit lost. Does Icecast do the onsite-to-webserver streaming? Or does it do the webserver-to-viewer streaming? | 14:11 |
| tsglove | Or both? | 14:11 |
| CarlFK | icecast is the server | 14:12 |
| CarlFK | clients (viewers) connect to it, it sends the media stream | 14:12 |
| tsglove | CarlFK, ok ok... | 14:13 |
| tsglove | And, I mean, I am no expert... this is why I am asking so many questions. ---- Say I am onsite (on the event), and I am streaming. Would I connect the Numato Opsis board to a linux machine? | 14:13 |
| CarlFK | you can put an html5 player on a web page, the html for that page on your server that serves 1 static page of html | 14:13 |
| tsglove | How do I get the stream off the linux machine? via ffstream? | 14:14 |
| tsglove | CarlFK, ok, that helps me understand the setup better. Icecast will search the video (WebM I reckon?), and the viewer will use a simple html5 player. | 14:14 |
| CarlFK | https://code.timvideos.us/projects/ | 14:15 |
| tsglove | on my way! | 14:15 |
| CarlFK | that picture shows the various things that make up the whole stack | 14:15 |
| tsglove | ah wow! I saw that page a while ago, and didn't see all the data. My fault. | 14:16 |
| tsglove | It's all there =) | 14:16 |
| CarlFK | the "streaming system" is another server - current code is deprecated, no idea what the state of the re-write is | 14:17 |
| tsglove | Ahh... and I could maybe replace the "streaming system" with Icecast... | 14:18 |
| tsglove | Next event is in October, yet I want to get a head-start on development | 14:18 |
| tsglove | Not feeling particularly good about going with Livestream once again. | 14:19 |
| CarlFK | how did you to FB? | 14:19 |
| CarlFK | someone just asked me for that for an event that has passed, but I am curious | 14:20 |
| tsglove | CarlFK, happy to help all I can. | 14:20 |
| tsglove | Well | 14:20 |
| tsglove | I was using Livestream | 14:20 |
| tsglove | and on the livestream.com "dashboard", there was simply a on/off switch to stream in parallel to Facebook Live. | 14:20 |
| tsglove | It then linked with my account to Facebook, I reckon it grabbed the needed credentials, and off it went. | 14:21 |
| tsglove | The biggest "yeah!" was the whole critical mass of Facebook. More people watched because they're already there. | 14:21 |
| CarlFK | meh never mind | 14:21 |
| CarlFK | yeah - livestream too hard | 14:21 |
| tsglove | And more people commented because they're already logged in... yet the comments were pretty much toxic 99% | 14:21 |
| CarlFK | swell | 14:22 |
| tsglove | Plus the whole "We are taking down your video stream because copyrighted music..." | 14:22 |
| tsglove | so with that, no longer interested in streaming to Facebook Live anymore | 14:22 |
| tsglove | I tried it because it was a simple on/off click. Yet next time, I won't be doing that. | 14:22 |
| CarlFK | https://github.com/CarlFK/voctomix-outcasts/#getting-started--demo | 14:23 |
| tpb | Title: GitHub - CarlFK/voctomix-outcasts (at github.com) | 14:23 |
| CarlFK | that gets vocto up and running with test patterns. | 14:24 |
| tsglove | Is this Voctomix... what part of the stack? | 14:24 |
| CarlFK | mixer | 14:24 |
| tsglove | ah ok ok | 14:25 |
| CarlFK | right now I am trying to make this work https://github.com/CarlFK/video-stack-deploy/blob/usbstick/scripts/mk_usb_installer.sh | 14:29 |
| tpb | Title: video-stack-deploy/mk_usb_installer.sh at usbstick · CarlFK/video-stack-deploy · GitHub (at github.com) | 14:29 |
| CarlFK | close, but bumping into things like: grub installer can'f find the ssd | 14:29 |

| tsglove | CarlFK, I am not a super expert, yet I would be happy to help you test things. Let me know if I can do anything | 14:59 |
| CarlFK | any idea how to grab a single frame from a v4l device ? | 15:50 |
| CarlFK | I've done it, always seems awkward | 15:50 |

| sam______ | mithro: could you help me understand what all needs to be programmed on the opsis board for a "full" load? | 19:53 |
| sam______ | mithro: my board is in some funky state and I can't seem to re-flash it properly | 19:54 |
| sam______ | mithro: or I just know the proper commands and order of them :/ | 20:13 |
| sam______ | mithro: I know youre busy, so thanks in advance! | 20:13 |
| sam______ | cd | 20:14 |
| *** danielki has quit IRC | 20:16 | |
| CarlFK | sam______: what do you mean by full? | 20:18 |
| sam______ | heh, thought I might get that question | 20:19 |
| sam______ | whatever it takes to get the board to the state it was shipped in | 20:19 |
| sam______ | right now the board it outputting scrambled video and doesnt shows up as /dev/video0 and /dev/ttyACM0 | 20:20 |
| sam______ | FX2 seems to come up in a unconfigured state | 20:20 |
| sam______ | in order to switch to JTAG mode I have to move a jumper on the board next to the FX2 | 20:21 |
| CarlFK | the state it was shipped in isn't a good goal | 20:26 |
| sam______ | yes true, but that at least will tell me it still works | 20:32 |
| sam______ | I just need to get the flashing process down so I can make changes and test | 20:33 |
| CarlFK | I suspect this is a better goal http://paste.ubuntu.com/24336175/ git describe: v0.0.0-267-ga1d5605 | 20:37 |
| tpb | Title: Ubuntu Pastebin (at paste.ubuntu.com) | 20:37 |
| CarlFK | we kinda have the concept of dev/test/stable but it gets out of date really fast | 20:38 |
| sam______ | sure I'll give that branch a try | 21:04 |
| sam______ | tim did mention that the docs for flashing/prgramming are out of date.. | 21:04 |
| sam______ | do you recall which commands you used to program the board? | 21:05 |
| sam______ | also is that pastebin from the /dev/ttyACM0 ? | 21:06 |
| CarlFK | I didn't program it - was left this way after some testing a few weeks ago | 21:10 |
| CarlFK | yes /dev/ttyACM0, | 21:10 |
| *** danielki has joined #timvideos | 21:11 | |
| sam______ | ok thanks, ill play around some more when I get home | 21:12 |
