Re: 4.19 kernel 64 bit support - please report issues here

bcm2835_mmal_vchiq: Failed to open VCHI service connection (status=-1) is an odd one. One of the main changes with 4.19 is that all the VCHI services (V4L2 for the camera, codec, vcsm, and should have been bcm2835_audio for audio) should all be loaded as platform drivers from the main VCHI driver. ...

Re: ffmpeg still activates the Camera LED ?

You have to know there is no spoon camera LED. So there isn't an LED, but you keep on talking about it. As I said, it's not our sensor so support is what it is. I have found a minor quirk that on shutting down the sensor the firmware will always set the camera LED line low regardless of disable_came...

Re: ffmpeg still activates the Camera LED ?

a) If your camera module has a switchable IR cut filter then it is not one made by Raspberry Pi. Support requests should really go to your camera module manufacturer. b) From the Pi firmware's perspective the LED is generally tied to the power control on the camera module - if the power is turned on...

Re: Dual HDMI?

I wonder if that would work for HDMI plus DPI/VGA ("Gert's VGA666)? It might, and that would allow two full size screens. I don't think the VGA will support full HD screens. I could be wrong, I haven't tried it. If I can find my VGA666 board, I will. My HD monitor has VGA input. Having checked the ...

Re: rawcam and corrupted trailer

The CSI2 receiver peripheral takes a start and an end address, so should never exceed those bounds. Indeed it can work in a circular buffer mode where it'll return back to the start should the amount of data exceed the buffer size - that mode hasn't been tested for a VERY long time, so I couldn't sa...

Re: Image Processing 4K images on a Raspberry Pi

My first question would be how do you plan to connect the GoPro to the Pi (or any other SBC)? The Pi has no HDMI input, and the add-on board that does support this maxes out at 1080P50. H264 decoding on the Pi also maxes out at 1080P, so if there is a way of streaming encoded data off the GoPro, the...

Hello 6by9, You have to make your output look exactly like the AR0323 - not an easy task.

This imager (AR0323) is a p...
