Pi Camera module v2 not working in Chromium/Electron with kernel v4.4 #1498
Comments
Why duplicate the issue - #1499 ? Unrelated to #849 - GStreamer is objecting to particular formatting of an H264 elementary stream. |
@6by9 sorry for the duplicate (and pinging an old unrelated issue), I had connectivity issues. Did not have the chance to test with a V1 camera. Here is the full log with
Also tried with latest electron

Your app is asking for a 0x0 YU12 image - that sounds a fairly unhelpful resolution, even if it is relying on V4L2 to clip it to a valid range (16x16 is the minimum supposedly supported on Pi) Admittedly something odd is going on on the GPU side - 16x16 doesn't return any buffers. 24x16 and 32x16 do. 18x16 doesn't. I haven't run any extra tests yet to find exactly the limit. I would however suggest you investigate why your application is asking for such a low resolution. That sounds like a bug on that side, possibly down to not supporting drivers that advertise stepwise resolution support from VIDIOC_ENUM_FRAMESIZES (see http://hverkuil.home.xs4all.nl/spec/media.html#vidioc-enum-framesizes) (edited to correct the requested resolution) |
I don't think there is anything specific to the app itself, here is the JavaScript source code, and it is basically just Chrome's navigator.getUserMedia, that does not look like it allows any format/size customization. |
From the docs section "Examples/Width and height"
So you can ask for specific width and height. Note too the main banner heading:
I can fix the underlying issue, but you'll get a 16x16 image streamed into your browser - it will look terrible, and that is a result of the app asking for something silly. |
Indeed, I refered/linked to an incomplete translated page, will try the navigator.mediaDevices.getUserMedia with different sizes and report back. Thanks! |
Still no luck tonight with this code (working thanks to this polyfill):
Got the following output:
So it looks like width/height contraints won't impact the format. Also, getUserMedia does usually looks good on OSX and Linux, is this 16x16 issue ARM specific? |
The app is still asking for 0x0, so it's still resetting to the default minimum of 16x16 which we know has issues. I am still trying to pin down why it doesn't work. Most USB webcams only support specific resolutions. TBH My simplest fix is going to be reset the minimum from 16x16 to 32x16 by bumping MIN_WIDTH at https://github.com/raspberrypi/linux/blob/rpi-4.4.y/drivers/media/platform/bcm2835/bcm2835-camera.c#L39. It'll work and I'll close this issue, but you'll get rubbish pictures - you need to work out how and why the framework you're using asks for such a silly resolution as that is not a kernel issue. |
The exact same code with a Logitech C920 webcam plugged on the Pi (USB) does work and produce a very good looking image. Is there any chance that it only tries to grab a 0x0/16x16 frame to test if the camera actually works before switching to a better resolution? Is there a way to get similar debug output than EDIT: Just created an issue on Chromium bug tracker: https://bugs.chromium.org/p/chromium/issues/detail?id=616007 EDIT 2: or maybe it just tries to grab the default resolution, the C920 first resolution in the list is 640x480, probably acting as default? Maybe a fix would bt to add a similar default/native discrete resolution for the bcm2835_v4l2 module? EDIT 3: Also tried https://webrtchacks.github.io/WebRTC-Camera-Resolution/ (from this blog post), that polls several resolution, and it fails for every resolution using the camera module with a With the C920 plugged in:
With the Camera module v2.1 plugged in:
|
There is a default resolution set on the Pi - 1024x768 JPEG.
Your app asked for 0x0. We checked against our capabilities and returned the closest match - 16x16. It looks like the UVC (USB Video Class - almost all USB webcams) driver selects the default resolution advertised by the webcam - https://github.com/raspberrypi/linux/blob/rpi-4.4.y/drivers/media/usb/uvc/uvc_v4l2.c#L176 I think you must be missing something in your config. I doubt it's the latest code as it hasn't been updated in almost 2 years, but https://src.chromium.org/viewvc/chrome/trunk/src/media/video/capture/linux/video_capture_device_linux.cc line 258 is the call setting up the camera. Note that there are width & height parameters passed in to there. Google for "chromium getUserMedia resolution" seems to throw up a bundle of hits, including things like https://bugs.chromium.org/p/chromium/issues/detail?id=312928 where someone else was having issues trying to request a resolution. Have you followed all of the recommendations there? I'm going to create a patch to shift the minimum res to being 32x32, otherwise I'm going to waste too much time on a calling app issue. |

@6by9 Thank you for your time and help, I know it is precious. We will see what the chromium folks say on the ticket I've created. I still think it's not an issue from my side (but indeed it may be a Chromium issue) as https://webrtchacks.github.io/WebRTC-Camera-Resolution/ works and properly set constraints for every combo (device/os+camera) I can try it with, it only fails with the Pi + Camera module. For instance, here is the related output on the Pi for the C920:
And here it is for the Camera module:
https://bugs.chromium.org/p/chromium/issues/detail?id=312928 is related to multiple tab locking, I'm only starting a single electron app on a single url (nothing else is running on the device). Thanks! |
No, the first 11 comments are all related to setting the resolution. Multiple tabs are only mentioned in comment 14 causing the issue in comment 13. Old commit, but may explain some things: https://chromium.googlesource.com/chromium/src/+/1577a17cdb0fe92f3e2dcd1ea2327ea814ca6549%5E!/
That code was removed in the patch, but that implies STEPWISE is not supported. The bug report is still open, but that may be an oversight. PR to increase minimum resolution to 32x32 has been merged. Either rebuild your own version of the kernel based on top of tree, or wait for an update to https://github.com/Hexxeh/rpi-firmware that can be collected with |
rpi-update kernel contains @6by9's increase of resolution to 32x32. It may be worth re-testing with this update. |
Ok so I got it working with https://simpl.info/getusermedia/sources, but as predicted, I get a terrible image quality.
Still no luck with custom resolutions: https://webrtchacks.github.io/WebRTC-Camera-Resolution/
I'm running an up-to-date Electron EDIT 1: Just found that I can simply add the https://simpl.info/getusermedia/sources outputs:
Which links to this file: That confirms your suspicion:
So http://crbug.com/249953 it is. Any chance that the Raspberry Pi could provide both discrete and stepwise resolutions? |
No, they're mutually exclusive, reported back via a union - see http://hverkuil.home.xs4all.nl/spec/media.html#vidioc-enum-framesizes and http://hverkuil.home.xs4all.nl/spec/media.html#v4l2-frmsizeenum. It looks like they have already fixed it to some degree with the updated code I linked to, and it makes a call over which resolutions it wants to query for. Are you feeling brave and fancy compiling top of tree?! Unless your version has long term support, I suspect that is all the Chromium guys are going to direct you to do anyway. |
BTW You're going to hit an unsupported at https://chromium.googlesource.com/chromium/src/+/51.0.2704.54/media/capture/video/linux/video_capture_device_factory_linux.cc#71 too, for frame intervals (aka frame rate). |

Being excited to play with webRTC on the Pi, I obviously really like this idea. I guess we could advertise relatively standard resolutions in the
That would fix 99% of the webRTC use cases.
I don't really get the relation between chromium's video_capture_device_factory_linux.cc and the code you linked webrtc's device_info_linux.cc Though I'd gladly spend some time digging into it, I am a bit clueless regarding the step needed to compile top-of-tree of |
YUYV is not the ideal format on Pi. I'd recommend you use V4L2_PIX_FMT_YUV420. My bad on directory. I'd followed https://www.chromium.org/developers/how-tos/get-the-code to grab the depot-tools and then So first step is to get ToT building, expecting it still to fail. |

Hey together!
Can't tell about Pi OS based on bullseye. I am going to check the dmesg once I have enough time. Maybe in the meantime someone can tell if the issue appears too for him/her? |
Hi! Sorry if I got lost somewhere in this longish thread, but why is this issue closed? It seems it was closed as a duplicate of #1499 in #1498 (comment), but #1499 was also closed as a duplicate of this one. In any case, the issue still exists in Bullseye (Chromium or Electron doesn't detect the Raspberry Pi v1 camera module), so it'd be good to keep this open, linking to the currently open corresponding upstream bug: https://bugs.chromium.org/p/chromium/issues/detail?id=1406830. Thanks! |
Heres the additions the pi foundation added to Chromium in the past, afaik it's now used from the official debian Sources https://github.com/RPi-Distro/chromium-browser/files/7829777/camera.txt |
See RPi-Distro/chromium#23 for reference |
It's closed because that issue was solved - Chromium didn't support V4L2 camera drivers that advertised the resolutions as The issue you're probably hitting now is that Chromium doesn't support libcamera, and the default camera stack for Raspberry Pi OS is now that. I believe the preferred route for supporting libcamera within Chromium is going to be via Pipewire, but I could be wrong. |
I'm hitting the issue even using the legacy camera stack; which shouldn't happen if Chromium is now patched as above, if I understand correctly. This is using a Raspberry Pi 3 B and a camera module v1. I've detailed my findings and workarounds in https://forums.raspberrypi.com/viewtopic.php?t=351986. |
@andi34 it doesn't appear that this custom patch has made its way in either Chromium or the Debian package of it; see the patches used in: http://deb.debian.org/debian/pool/main/c/chromium/chromium_113.0.5672.126-1.debian.tar.xz, which is for the Debian chromium package in Bookworm. Looking at the chromium source http://deb.debian.org/debian/pool/main/c/chromium/chromium_113.0.5672.126.orig.tar.xz shows the patch hasn't been applied there either. Unless I've missed something, it means this bug is still relevant. Could this issue please be reopened? I've also requested the upstream bug https://bugs.chromium.org/p/chromium/issues/detail?id=249953#c25 to be reopened, as it's been archived without resolution while the source code still refers to it, calling |
The patch was / diff was shared by @jc-kynesim while I asked for a solution. And yes, it is not added to the official chromium sources. I was told the pi foundation used it's own sources and later shwitched to the mainline package. |
Besides that it's also still an issue on a 32bit PiOS to use the v4l2loopback module as it fails because of the mixed arch of the kernel and Userland.... |
Related, see an account of my struggle/hacky workarounds using v4l2loopback (I had to switch to 32 bits kernel/userland to avoid the above issue you linked) here: https://forums.raspberrypi.com/viewtopic.php?p=2109999#p2109999 |
I'm struggling to make the Pi Camera module v2 work inside Chromium/Electron (while raspistill and python PiCamera do work) on an up-to-date Ubuntu Mate 16.04.
When I start electron v1.1.0 (Chrome 50.0.2661.102) on this url: https://simpl.info/getusermedia/sources
I get a black square with the following logs inside
/var/log/kern.log
:After that, the camera module seems stuck and any further
raspistill
won't work.Any ideas?
Might be related to #849?
