Re: V2 HQ Housing Assembly Focus issue

Hi dnaman, Well, that's the difference between the universal tool (with interchangeable lenses option) and the usecase-optimized solution. If you are focused on using 6mm lenses only, adjusting the mounting plate for your specific case may be the best way. Is it possible to buy the mounting plate(s)...

Re: Gstreamer Pipeline from Mac to Pi

Hello phowe, I also tried using the UDP protocol, but it was not working on my Wifi at home and I couldn't figure out why. This is a regular network magic to figure out. You should have the single network (not mixed with other sub-networks or bridges), check "wifi clients isolation" settings on your...

Re: Stereo Pi V2 with Ubuntu Mate 20.04

Hello karlfra, You need to choose the subsystem you are planning to use with the cameras. As you may know, RPF did dramatic changes in the video subsystem (announced here first, and more details later here .) To say briefly, you can either use the old mmal-based approach (using older kernel and firm...

Re: Using StereoPi Lite with RPi 4B

Louise, the short answer is no - it's impossible to use RPi4 instead of CM4. You can consider CM4 as a regular RPi4 with all connectors removed, reduced PCB, and a lot of special connectors exposed. So RPi4 is physically incompatible with the CM4 and can not be installed instead.

Re: Connecting StereoPi to other RPi modules (Compute Module 4 sold out in UK)

Hello Louise,
StereoPi is using the particular version of Raspberry Pi, the CM4. Unfortunately, you can't use the regular Raspberry Pi instead of CM4 :-(
CM4 is difficult to find these days (chipageddon is not over yet). But if you buy the StereoPi V2 Camera Kit, it includes CM4.

Re: Video Streams Not Working

Hi Blinky,

In the latest release of SLP2 (0.12.4) we've updated the video decoding part in the administration panel, and now it works with most of the browsers by default.

Re: Capturing video GStremer

Uh, got you, thanx!

We've tried to use glvideomixer for bigger resolutions and color images, but the performance was poor. The idea was to find the workaround for the stereoscopic mode until the Bullseye new video subsystem fully supports it. Now we're still on Bullseye.

Re: Frame rate always around 18 FPS

Hi amphi, All video-related settings are stored in the stereopi.conf file. You see, in some cases, the combination of the specific settings can cause this issue, but we are not able to reproduce them too, so they are difficult to catch and fix. As for the HQ camera, I remember that the sensor mode i...

Re: Gstreamer Pipeline from Mac to Pi

Hi phowe, As a rule, embedded systems usually do the output streaming, and your use case is a bit unusual. Also, Python is not the best choice for video processing (especially for high resolution and simple things like barrel distortion). I guess you need the low latency too (VR display) - in this c...

In any event, I have solved the immediate problem: On my LAN, I have two wireless access points. I tried the alternative access point and the SP2 happily connects to it. Du...

Re: How to connect via WiFi

srathinagiri, let's try to debug this step by step. 1. Please forget about rpiboot, you don't need it at all with your CM4 Lite and micro SD. Please remove both jumpers USB_CLI and RPI_BOOT and keep them in a safe place. 2. Let's test the Ethernet connection first. a) Please check that you are conne...

Re: How to connect via WiFi

Hi dnaman, Possibly you have the frequency band issue since some countries have specific requirements for the WiFi setting. You can find the country settings in your wifi router, and set the same parameters in the cosmostreamer.conf, so both StereoPi2 and your WiFi equipment works in the same freque...

Hello Shai, At the startup, cameras are not turned on at all. You can set the parameters you need in the software you are using. Also, if you are using the stereoscopic mode, you can't set different parameters for cameras - they are automatically synchronized. But for the independent use of each cam...

Sorry, I didn't play with the projection 3D mapping approach, so I can't advise on the laser hardware to use. Maybe someone else on this forum has played with this and can provide us with insight. :)
