Hello.

Just a query about whether it's possible to be sending the h264 video from the mipi-327 camera unedited, so that it can be displayed in a video element on a web page.
The way we are currently doing this, is using a library on the client side called jmuxer, which, through a websocket directly is able to display arducam cameras. Is there something similar with the mipi-327 camera as seen in libcamera-examples?

Hello,

Asking around what would be the best way to stream the mipi-327 camera over wifi, we have been looking into using gstreamer.

Is there any other library available to stream the camera (preferably mjpeg)

Thanks

Nathan

@veye_xumm Thank you for the quick response! Do you know if there will be support coming in future?

We are trialing using the banana pi m2-zero instead of raspberry pi zero going forward.
Has anyone had success running a veye arducam on the bananapi?

Thanks in advance.

Nathan

We're getting the following debug information when the camera doesn't display to screen.

It doesn't do it all the time but it's come up often enough that it is a serious issue. We found if you restart the pi that it displays camera.

@veye_xumm were able to get it working. This is resolved for us.

@veye_xumm We're using buster.

Here's the steps i followed to replicate issue:

1. run ./enable_i2c_vc.sh
2. Run ./camera_i2c_config
3. Run a few commands on i2c (mirror mode)
4. Run ./veye_raspipreview -t -1 -p '0,0,1920,1080'

My system does not have an i2c line but is getting it from the csi cable. Camera and i2c enabled in raspi-config.

Expected Result:
Camera appears on screen

Actual Result:

./veye_raspipreview -t -1 -p '0,0,1920,1080'
before create camera com time out -1
Hardare version: 9000c1
before create camera com 
mmal: mmal_component_create_core: could not find component 'vc.ril.rawcam'
mmal: Failed to create camera component
mmal: main: Failed to create camera component

I did another test and worked out it's not likely to do with i2c, i reformatted sd card with a backed up image and it does the same thing as this.
I can confirm that the camera IS working as I have another image which uses the VEYE_MPI-327 and it's working without issue,

Here's the verbose log.

@veye_xumm I was just looking at the i2c program. Call this resolved.

@veye_xumm
I'm not familiar with the raspividyuv program.
I am using the following command piped to my python program:

LiveCamera.pipe = subprocess.Popen(['/home/pi/veye/veye_raspcam/bin/veye_raspividyuv', '-t', '0','-o', '-'], stdout=subprocess.PIPE)

Got it going but it appears only to run maybe a few frames per second.
Also I'm neeeding a time frame in order to get this working. It's very important that we get this flipping going for a client. To be specific:
We're using a pi zero with a usb camera and MIPI-327 and both of these cameras need to be able to be flipped in the event the camera goes upside down. We're using python because a library exists for it that allows us to display the video streams without a gui. Arducam software needs to be able to run at 30fps at 1080p.
Isn't MJPEG an option that can be used? i just need a way to get the right data from the mjpeg stream and then i'm okay.
What data is being sent based on the codec option MJPEG or H264. I just need to know where the data is and use opencv to convert it to an image.
