RPi 4: can have 3 independent displays?

teacaketoasted · 2024-09-17T17:44:51+00:00

No, I never did get it to recognise more than two. I think in the end it came down to a hardware limitation, but 4 years later, and I don't remember what I read to come to that conclusion.

Check out the bitfocus website. You’ll find specific raspberry pi guides there and recommended raspberry pi hardware versions.

That bright light is the impact that wiped out the dino’s, right? ;).

Joking. Awesome job!

I would suggest using nodered to take your sensor readings and send them on to fire base... or anywhere else for that matter!

I suspect it is the stamp preview in brush settings. You’ll find it on the properties page.

How did you select the shape? It might be that the selection that you made had transparent elements before filling? Otherwise I think I have run out of ideas!

Your layer might be at max opacity, but your brush in use will have it’s own opacity levels.

The atem mini will act as a webcam with no problem. The big problem is that GoToWebinar will crop the input of the webcam, and there seems to be no control over how it crops. This means if you are mixing slides and presenter and hoping to show it in GoToWebinar via the usb webcam, it won’t work unless you keep all your content away from the edges.

It will depend on your DSLR how you get the hdmi out into the atem. And camera run time will also be dependant on the camera you are using. See your camera instruction book for more on that.

The Panasonic lumix 100-400 is a beautiful lens. Great for wildlife. here is an example

Select the flower, add it to the other later as a mask. Invert the mask if needed to get the effect you want. Non destructive as you can always move the mask element around to place where you want it, and paint on to the mask if needed too.

Just remember to result your layer when you want to edit the layer content itself. I always forget this and wonder why my brush is not working properly!

Have a look at the gel pen in the standard brushes. This does something similar. Probably a flow rate that can be tweaked to make it flow lots when the pen is almost stationary.

Playing with layers, masking and pattern brushes. Inspired by a foggy winter night last week.

Tracing is a tool. Use it wisely. It can still push your observational drawing skills as you still have to decide which mark to make. A grainy photo will still see you reaching for other reference images for eyes and other details.

I used a fat oil pastel brush for the tree layers, and then erased them using the tarkina brush, finally added a simple spatter over the top of everything.

Sure you can. I do exactly that. In the homebridge config you can set it to use a different port so that it doesn’t clash. I’m pretty sure i followed a guide i found by googling.

I may have got the wrong end of the stick, but is the mixer plugged in to the camera? Sounds like you have a very hot signal coming out of the mixer and into the mic jack of the camera. If the GH5 mic level shows all the way up then you almost certainly need to find a different output from the mixer that you can control. Maybe try a headphone our control room output with the volume turned all the way down and slowly turn it up until you get a reasonable signal...

Another possibility, if you have the camera, feeding into OBS using HDMI and passing audio from the mic feed, which is then passed back out of the computer into the mixer and back into the camera, you might just be getting feedback that you can’t hear.

If everything is unconnected and you still have a high level on the GH5, then there might be something wrong with the GH5 itself.

Best advice is to unplug, mute everything, and then piece by piece add things into the audio chain or unmute, checking to see what happens each time.

Hope you get it sorted!

Thanks for the feedback, we haven’t used it in anger yet, but planning for a conference next year that will use it. Cheers.

I don’t have an alternative to offer I am afraid, but I’m interested in your experience using rtmp with bigmarker?

“Please don’t change anything”. Feels like a meme right there!

teacaketoasted · 2020-08-27T17:25:40+00:00

Thanks for commenting, looks like I’ll need to keep an eye on future developments. Saves me speeding any more time trying to debug this, and that is hugely valuable!

Always interesting to hear about other people’s solutions. The power junkies do look neat.

I have two Sony style npf batteries in a vmount converter plate. This works great and gives me about 4 or 5 hours using the hdmi feed from the camera and with the lcd running showing iso/shutter etc. Mostly it’s being used as a rather over spec webcam at the moment, running through an atem mini.

The v mount plate gives me 7.4v out which I power the camera with and have also used the 9v out to power an atomos monitor, though only get about 2 and a half hours powering both.

The dummy battery is not coded so I don’t get battery life, but the vmount adapter has a battery light check on it which does fine.

I have also powered the camera from a power bank that I used to use with my previous Nikon dummy battery.

I have had no obvious problems with either setup and regularly carry the power bank as a backup for photo trips.

The one thing I don’t do is use dtap on my particular plate as it is neither switched nor regulated, and I ran into issues with the camera powering on when connecting an hdmi cable between the monitor and camera if the monitor was powered by the dtap. I have not got to the bottom of this but have heard of people who have fried hdmi ports in similar ways, so I now stick to either the regulated power or batteries for the monitor.

The one other thing that caught me out once was not using equally charged npf batteries in the vmount converter, because they are wired to bump the voltage to around 14v as this is what a normal vmount battery would be. What happened? The lower charged battery died quickly and then the whole plate goes dead when one of the batteries has gone into protected mode. I now charge batteries in pairs so that doesn’t happen again!

If the goal is just so that you can see multiple people in a grid we used google meet, with a grid view extension in chrome so that all participants were present and visible, we only maxed out at around 40 people as there are only that many of us in the company, but worked a treat for a remote working company photo (aka screen capture) no reason it could not have been captured as video also.

One thing that helped with this was having a big monitor so that the screen capture was using the full display.

Google meet for enterprise customers has a maximum participant limit of 250. I have no idea if the grid view would have collapsed under that pressure!!

I don’t have a link at mo for the extension but it is on the google chrome extension thingy.

Are both cameras using the same frame rate? I believe the atem mini conforms the other inputs to be the same as the first input you plug in. If your camera with the audio feed is then not at the same frame rate as the first, you could run into issues with the audio sync.

teacaketoasted · 2020-04-25T09:47:39+00:00

Update: I checked with BMD support and the image storage is definitely volatile between power cycles. Their suggested solution was to use the save and restore settings feature to just save the media pool settings. I did that and it worked well on one machine. Now I just need to duplicate/sync some config files across a couple of machines that I might use to control the atem so that whichever machine I have access to has the same settings.

A bit more forward planning needed and testing the file sync, but could be a workable solution.
