balena-cam's Issues

Build better UI

Build UI that:

Auto starts video stream, on page load.
Has buttons to access the resin-wifi-connect functionality.

Error with "VIDIOC_STREAMON: Invalid argument"

When I loaded the balena-cam to Raspberry Pi 4B, the balena-cam service dies and infinitely restarts.

When I ssh'd into the Docker container and tried to execute the Python logic, I could reproduce the same error by importing cv2 and running cv2.VideoCapture(0).read(). The returned values for read() are (False, None).

Following is a snippet of log from the balena-cam service:

Ideas!!

any ideas for adding timestamp on the stream gsstreamer?

Trouble building (in local mode) on a Raspberry Pi 4

Finally got this working on a Pi Zero W by changing the GPU memory settings.

Moving to a Raspberry Pi 4, with local deployment, and after balena push x.x.x.x

some services failed to build:
	balena-cam: manifest for balenalib/raspberrypi4-64-debian:stretch-20190612 not found

Changed first line of Dockerfile.template to

FROM balenalib/%%BALENA_MACHINE_NAME%%-debian:stretch

Now got the error

[Build]   [balena-cam] E: Unable to locate package libjasper-dev

Commented out the line for that in the same dockerfile.template, but I'm sure it wouldn't be there if it wasn't needed, so I'm sure that'll cause problems down the line.

Now getting the error:

Doesn't run successfully when pushed to balena; syntax error

From the current master branch, I cloned and then pushed to balena. Image built ok and has deployed to my device (raspi 4)

However the balena-cam container is failing to start, falling over with a syntax error. Seems to be complaining about type hinting in pyee. Has some dependency not been pinned and an external release rendered this code un-runnable?

push error

When pushing, the remote build fails with the error:

Change video resolution

Is it possible at all to change the video resolution? It appears to be drastically low quality :( I was hoping for some environment variable to use for this

Video stream does not work in Safari on iOS

When accessing balenaCam from an iOS device using Safari (even via LAN) the video stream sits on 'Connecting...' with a spinner.

Highlighted by user noschvie in this forum thread: https://forums.balena.io/t/how-to-get-balenacam-to-balenadash/14424/2

I've tested and confirm this is the case on iOS 12.1.4

libjasper-dev missing again

I saw that this has been an issue before and that there was a fix at that time. Now builds from master are failing again due to the libjasper-dev package missing.

"Blank" screen in web browser

Hi. My balenacam is not working. When I try to access the WebRTC stream, everything but the stream itself loads.
I can double-click to go fullscreen etc - but no video.
The camera and RPI 3 A+ is confirmed working.

From the logs - the only weird thing is the .local address instead of the IP my computer is on?

Show date and time in stream

Is this possible?

No matching distribution found for async-timeout

Tried to push BalenaCam to a Raspberry PI Zero W today.

Got around the "missing GPG" error by changing line 6 to:
apt-get install -yq --allow-unauthenticated
...to Dockerfile.template

But this one about Python has me stumped.

libjasper-dev

Problem persists

: Unable to locate package libjasper-dev

Can not push project to balenaCloud

I recently pulled this project and tried to deploy it on a Raspberry Pi Zero W running balenaOS 2.32.0+rev1.

However I am unable to push this project using balena push <PROJECT_NAME>

This error can be easily be fixed by adding --allow-unauthenticated to the apt-get install -yq in the Dockerfile.template at line 6.

After that I encounter another issue that I am unable to solve, checkout the log (unrelevant bits have been removed.

Front conversations

Maybe not an issue but worth asking

Looking forward to drive this project using cellular data on either a sim USB or a dedicated HAT for Pi4on 4G. My question is, what further configuration it needs if any and if the stream data are being compressed from the host to the cloud. Having compressed data over cellular for the obvious reasons on 1080 stream. Has anyone have a say on it?

Add adapter.js

Add adapter.js (rtc shim) for cross browser compatibility.
Currently, it doesn't work on firefox.

Update references to balenaCloud application

Look for and rename any references of balenaCloud application to fleet

Invalid IP address issue

Getting the following error. UI starts as expected and is functional, but the stream is not being fetched correctly.

I am using typical RPi camera board, connected to a Fin board.

I'm planning on debugging the issue this evening as I have plenty of Python experience, but thought I'd post here in case this is a known issue.

My Fin is running in local mode, running containers, with the cam project running from one of the containers. Host OS is 2.46, so cam libs should all be fine.

Thx

Add access control mechanism.

Add some access control mechanism. (eg. Lock nginx's paths with passwd)

Feed stops after some short time (frames)

After fixing the setup by issuing the command modprobe bcm2835-v4l2 in a terminal, I was able to get a camera feed, but only for a short time.

After that, the browser screen goes blank, and I eventually get a sad smiley with some 'sorry' error message.

I tried changing a line to await asyncio.sleep(5)
from I think 0.2? to slow things down, thinking it might be too much data for the pi zero to handle.

It didn't actually slow the framerate down from what I could tell...

Any ideal? I guess I have to update a library...

Presisting in the cloud.

What is the approch to be able to save image to a remote location every 1 sec, for ever

Should offer API to get a single picture

Many projects don't need live streams. Would be great if we had an API which just gets the current picture. The cam could be even powered down if nobody uses it

Video stream does not work with balenaDash (WPE)

When accessing balenaCam from a balenaDash device (even via LAN) the video stream sits on 'Connecting...' with a spinner.

Highlighted by user noschvie in this forum thread: https://forums.balena.io/t/how-to-get-balenacam-to-balenadash/14424/2

I've tested with the current version of balenaDash and can confirm this is the case.

Cannot build: balena.yml is not a valid contract

Whether using balena CLI or git, I get the same error which is:

[Error]    The included balena.yml is not a valid contract, allowed types are sw.application,sw.block,sw.hal-module, stopping build
[Error]    Some services failed to build:
[Error]    Not deploying release.
[Error]    Upstream API server/DB error:

 ! [remote rejected] master -> master (hook declined)
error: failed to push some refs to 'git.balena-cloud.com:g_corbin_haugen/sanderscam.git'

Any ideas of what I am doing wrong?

Thank you,

Fix connection error

A "ConnectionError: ICE negotiation failed" raises in some cases.

Suitable as use for a block

I'm not completely clear from the docs if this is suitable for use as a block?

The networking mode host looks as though it may be a problem when combining with other services which expose ports?

Error on fresh build: VIDEOIO ERROR: V4L: can't open camera by index 0

Hi,

After installing a larger SD card (a big jump... 4G-128G) the previous strange error I was having stopped (see issue 50)

16.12.19 21:26:09 (-0800) balena-cam VIDEOIO ERROR: V4L: can't open camera by index 0
16.12.19 21:26:09 (-0800) balena-cam Failed to open default camera. Exiting...

I changed the index of the video device to -1 and got the error
"VIDEOIO ERROR: V4L: can't find camera device" instead.

Issuing the command 'modprobe bcm2835-v4l2' seems to fix it, but it doesn't persist after a reboot. It seems a recent commit removed that check?

Now, it only fixed THAT problem. Now the stream runs for a second, maybe a few frames, then the whole thing stops. I suspect it's a bit much for the pi zero to handle, but if anyone is having luck with that hardware, it must be something else.

I'm trying now to change 'await asyncio.sleep'... to 5 seconds in server.py. I reckon that should throttle it enough to let the pi zero's tiny brain catch up.

Stable Rasberry Pi Zero W config?

Hi! Does anyone have a stable Raspberry Pi Zero W config they could share? I've tried a couple gpu memory settings... 128 and 256 but my camera will run for a minute or two and then lock up. Then the Balena supervisor restarts it I believe. I don't see much in the Balena logs for the device in the GUI, but Im assuming it is GPU memory related. Any advice / documentation for Pi Zero would be appreciated!

Main Branch Does not Build

It looks like some dependency has changed....

Flag to disable "Anonymize local IPs exposed by WebRTC" is expired in Chrome 86

[rahul-thakoor] this project required disabling the feature in browsers where the local IP address is hidden. In recent versions of Chrome, the flag is not available. It can be brought back with chrome://flags/#temporary-unexpire-flags-m85 but this is temporary.

We should find an alternative and possibly fallback to mjpeg streaming when WebRTC doesn't work.

Conform to RFC 1341 Content-Type multipart boundary specification

I've been toying around with this project on my RPi2 as a way of exploring the Balena concepts and got curious about the Content-Type 'multipart/x-mixed-replace' where a boundary is specified for each stream frame.

According to RFC 1341, section 7.2 The Multipart Content-Type, subsection 7.2.1 Multipart: The common syntax (Link: https://tools.ietf.org/html/rfc1341):

The encapsulation boundary is defined as a line consisting entirely of two hyphen characters ("-", decimal code 45) followed by the boundary parameter value from the Content-Type header field.

...

Thus, a typical multipart Content-Type header field might look like this:

Content-Type: multipart/mixed;
boundary=gc0p4Jq0M2Yt08jU534c0p

This indicates that the entity consists of several parts, each itself with a structure that is syntactically identical to an RFC 822 message, except that the header area might be completely empty, and that the parts are each preceded by the line

--gc0p4Jq0M2Yt08jU534c0p

Thus, the server.py code:

response = web.StreamResponse(status=200, reason='OK', headers={
        'Content-Type': 'multipart/x-mixed-replace; '
                        'boundary=--%s' % boundary,
    })

Should be changed to:

response = web.StreamResponse(status=200, reason='OK', headers={
        'Content-Type': 'multipart/x-mixed-replace; '
                        'boundary=%s' % boundary,
    })

Doesn't seem to be a big deal though, it seems to work pretty well regardless :)

Thank you for a bunch of great examples on how to use Balena!

Best regards
Daniel

Is this project working on latest balena infrastructure?

Hi,
This project looks fantastic, and should be a great starter for a something I'm working on. The problem I'm finding is that it doesn't display video in Chrome from my raspberry pi. The connecting spinner shows for a couple of seconds the disappears. The Chrome logs look positive:

Do sound as well

See: https://forums.balena.io/t/balenaos-startup/37794/39

Baseimage doesn't exist for the RPI 4

Current workaround is to add RPIs 4 to RPI 3 apps

Avoid unnecessary pip package installations when editing and rebuilding the source code

Since the Dockerfile.template file has COPY ./app/ /usr/src/app/ before the pip install instructions, each time one edits the code and rebuilds, all pip packages are reinstalled.

This takes some time, especially when working in local mode.

Thus, the Dockerfile statement
COPY ./app/ /usr/src/app/

Should be moved to after the pip install instructions

Fixing this will make it more convenient for people toying with and evaluating Balena to tinker with the code as you won't waste time reinstalling the same pip packages.

Transfer repo to balena-io-projects organization

We should move this one to the projects org since it looks like this project graduated from the playground :D

User would like to get live stream feed via public url

[rahul-thakoor] The current implementation of balenaCam has a client webpage that streams the video feed. It would make sense to allow the feed directly over the public url so it can be consumed directly in other applications. E.g Ant Media

No video, probable WebRTC problem on Pi4

I cloned the repo and followed the instructions in README.md.

I am using a Raspberry Pi 4, 4GB. Official Pi camera module v2 attached.

When I point my browser at the device public URL (https://xxx.balena-devices.com) the page loads and all seems to be going OK, until my browser looks like this with no video:

The text 'Double tap the video to enter fullscreen mode!' pops up if I move the mouse around.

In the device logs I see the following:

I suspect that error message is due to aiortc/aiortc#187. As far as I can tell it's unlikely to be causing the problem I see.

I've spent time trying to rebuild this project with newer versions of aioice and other packages, but failed to find a combination of versions which will build happily.

I have tried one other thing, which is to force mjpeg mode in client.js:

- if (window.navigator.userAgent.indexOf("Edge") > -1  || safariOnIos) {
+ if (true) {

This works: I see mjpeg video in the browser. So I suspect the problem is to do specifically with WebRTC.

Removing intermediate container 5e69f8b59472
The command '/bin/sh -c pip3 install aiohttp aiohttp_basicauth==0.1.3 aioice==0.6.10 aiortc==0.9.11 numpy==1.15.4 opencv-python==3.4.4.19 --index-url https://www.piwheels.org/simple' returned a non-zero code: 1

I see that https://www.piwheels.org/simple/av is completely empty. Is that a 'bug' by piwheels? I'm not sure how to tell.

My thinking was 'well there's no pre-built wheel, never mind, I'll just build it myself'. So I changed line 34 of the Dockerfile from --index-url to --extra-index-url. Rather than failing when it can't find a ready-build wheel for av, it tries to built the package.

[balena-cam]  Using legacy setup.py install for pylibsrtp, since package 'wheel' is not installed.
[balena-cam]  Using legacy setup.py install for av, since package 'wheel' is not installed.

It also tried to build pylibsrtp, which failed, but that is fixed by adding libffi-dev to the apt-get install list earlier in the Dockerfile.

I'm not sure if the fix I've made is the right one, since I'm unsure of the rationale behind the existing series of pip commands. In particular, I'm not sure why pip3 install av is a separate line in the Dockerfile, since aiortc already depends on av. If my fix is considered a win though, let me know and I'll open a PR.

Fleet configuration variables -- what is their purpose?

What is the purpose of defining these variables in the fleet configuration?
BALENA_HOST_CONFIG_start_x = 1
BALENA_HOST_CONFIG_gpu_mem_256 = 192
BALENA_HOST_CONFIG_gpu_mem_512 = 256
BALENA_HOST_CONFIG_gpu_mem_1024 = 448

Do they affect the HostOS, or all of the containers?
Perhaps a link to https://www.balena.io/docs/learn/develop/hardware/i2c-and-spi/#raspberry-pi-camera-module

would be helpful

Capturing video from second camera on balenaFin

I have enabled 'Dual camera mode' as per instructions for the balenaFin: https://www.balena.io/fin/1.1/docs/developers/#Dual-camera-mode
I also changed the Fleet Configuration. I get the following output when switching cv2.VideoCapture(0) in server.py to cv2.VideoCapture(1) to get the feed of the second camera.
Note: Works fine with main camera

Which is maybe consistent with this page on RTCPeerConnection from MDN?

Allow user to select video device using an environment variable

[rahul-thakoor] The video capture device is currently hardcoded to /dev/video
Allow changing that via a variable and fallback to /dev/video if the variable is not set.

It can be helpful when there are other video capture devices. see #68
