Re: Livestreaming to a web
AlexVega, I'd recommend you to download /opt/StereoPi and /var/www folders from the SLP and look at the code. All you need is in these folders. Look at the file names in the /opt/StereoPi/scripts folders: loop-mpegts-skybox.sh loop-mpegts.sh loop-record.sh loop-rtmp.sh loop-rtsp.sh loop-ws.sh record...

Re: 16MP Pi NOIR
Hi lawsey, There are two ways of capturing images. The first one (used in SLP) is using raspistill utility. It's a binary tool, which can capture any resolution you want. Please note, it automatically scales an image to the resolution you need. For example, if you request an 8MPix image from the 5MP...

Re: StereoPi Issue - Right camera input displaying magenta in hotspots
p.s. Atfphoto, I did one bad thing and asked the RPF Software development department head about this issue. As a result, we got an answer in this thread: https://www.raspberrypi.org/forums/view ... 0#p1842048

Re: Some questions before pledging V2
Mr.Burns, as I remember, all Arducam products have some extra features, but also require special drivers compilation and installation tricks. As a result, you can't use classic tools like raspistill and raspivid , which are the default and friendly ways to take images and videos on Raspberry. Our SL...

Re: Some questions before pledging V2
Mr.Burns, HQ camera has the only version. Here is the official webpage: https://www.raspberrypi.org/products/raspberry-pi-high-quality-camera/ Yep, it is IMX477 based Autofocus is another hardware, and syncing it is another trick. HQ cameras are syncing their image capture start time (i.e. triggerin...

Re: Some questions before pledging V2
Hi, Mr.burns, Stereomaton put such a detailed question, so I decided to not add anything :) As for your synchronization question, if you plan to work with HQ cameras, they have a native, built-in hardware sync feature (with nanosecond precision). You should enable this in Raspbian settings and conne...

Re: StereoPi Issue - Right camera input displaying magenta in hotspots
Hi Atfphoto, Looks like this issue is not solved yet in the Raspbian kernel. I'll do some tests with the latest kernel available to check this. I have one workaround right now for HQ cameras. It is possible to get two images independently (using two raspistill processes in parallel), but with the ha...

Re: Add a Record button to SLP
Zoldaten, unfortunately Stereomii can't answer our questions anymore...
We already added video and photo recording options to the latest SLP 1 (published now), and will publish a new SLP2 soon (hope this week) for the mass-tests.

Re: Bad gateway and no browser stream incoming after upgrading
Francesco, thank you for sharing your solution! :-) Zoldaten, our "shot" button has a special logic controlled by our scripts. No need to manually stop/start them. When you take a photo, scripts automatically stops raspivid, takes a photo, and run all live streams again. Here is the way we are takin...

Re: SLP max width/height params
Hi ALexVega, This resolution should be fine for the photo, but not for the video. You see, Raspberry Pi's GPU H264 encoder has a resolution limit (near FullHD). The only way to get a higher resolution is to use MJPEG compression. This is a bit tricky way. Our upcoming SLP upgrade and Quest 2 app wil...

Re: Stereo base distances.
All distances are the distances between the cameras' optical axis. I.e. the axis which is going through the center of the sensor.

Re: how to stream with USB ?
Hi Zoldaten, Are you try to do this using stock SLP, or the patched version (discussed there )? Please try to test it with stock SLP first. Right after the connection to the Android phone, it should show you pop-up window with the question like "Hey, do you want to approve using this accessory?". Yo...

Re: snapshot two pictures in the same vsync
Wasfan, this is the way we use in our OpenCV code. We capture a stereoscopic pair and then split it into left and right images. Our experience says this is the most comfortable way instead of working with separate images, and also the only way for stereoscopic video processing.

Re: Bad gateway and no browser stream incoming after upgrading
Hey Zoldaten, A few comments on your investigations: 1. When our scripts are running (run.sh), they are using raspivid. So when you try to run "raspistill", it shows you an error. For the manual console run of "raspistill" or "raspivid" please stop our scripts first by stop.sh. Note: if you try to k...

Re: Bad gateway and no browser stream incoming after upgrading
Wow. I never faced the stuck of 'vcgencmd get_camera'. More than a year ago, there was a bug in Raspbian. They updated AWB algo, and this broken stereoscopic support (our post about this , and the GitHub discussion with the Raspberry engineer). Right now, this bug is fixed in the latest kernels, but...

Re: New to Raspberry Pi
Mango, you can consider Skybox as a reference. And look for other alternatives (google "Skybox alternatives"). We played with Skybox a couple of years ago, hacked its protocol, and try to force it to work for the live stream. (We published all code and were in contact with the Skybox team after that...

Re: Stereo Equirectangular Projection Live Stream
Hmmm, interesting approach. Maybe our recordings from the 180 or 200-degree cameras can be viewed "as is".
I add this experiment to my to-do list.
As of now, all those transformations to be done on-the-go in our Oculus Quest application. We did a special shader for this conversion in a real-time.
