rpi3 camera v2 issues when over 720p

Postby jskier » Fri Feb 16, 2018 4:51 pm

Hi,

I'm having issues getting the pi3 (raspberry pi 3 b) cam (v2.1) to work at 1080p recently. It just zooms in; like it's not taking the options I pass per the wiki:

$this->bbcode_second_pass_code('', 'options bcm2835-v4l2 max_video_width=3240 max_video_height=2464')

From the Archlinux wiki:
https://archlinuxarm.org/wiki/Raspberry_Pi

Kernel:
Linux alarmpi 4.14.18-1-ARCH

Video mem is at 128, and the camera works fine at 720p or less.

Anyone else having this issue?

First off: "The wiki" is kind of ambiguous in the internet. Please post a link, when referring to an external site. Also the used board would be nice, assuming Raspberry Pi 3.

How exactly are you accessing the camera? Try changing the resolution with Video4Linux or via the OpenMax interface. You could try this call to Video4Linux2 to get the supported resolutions [1]:

$this->bbcode_second_pass_code('', 'v4l2-ctl --list-formats')

Maybe this [2] might help you as well.

Sorry, meant to include the Archlinux wiki, posting from a phone. As noted in a few places, yes rpi3 board.

I get some output from the suggested command, however no resolutions, just types (mjpeg). I'll post the output when I get to a computer.

Here is the output from:

$this->bbcode_second_pass_code('', 'v4l2-ctl --list-formats')
