Could we get a simple option to perhaps scale the timestamp size? It's verrrry tiny on my 1080 stream!

Otherwise, this is great.

is there any thought about adding audio?

Hello. First of all, I inform you that I am writing this article through a translator. Please excuse me.

A few days ago, I was using a program that was released as cam2ip-1.6-64bit-cv2.zip, but there was a power outage once due to an accident, and after that, the console displays an ERROR: SampleCB() - buffer sizes do not match error, and it is not running normally.

To solve this problem, I have downgraded to 1.5 version, no cv2 version, and run to 32bit version, but no progress has been made.

The main command to use is cam2ip.exe -width 640 -height 360, and using cam2ip without any further syntax did not run normally. and i'm using Windows 10

OpenCV3.4.3 prompts "[mpjpeg @ 0x7f3e844b0580] Expected boundary '--' not found, instead found a line of 20 bytes" when calling IP camera. Sometimes good, sometimes bad.

I tried both "cam2ip-1.5-64bit.zip" and "cam2ip-1.5-32bit.zip" version on 4 different computers (2 Win 7 & 2 Win10, all 64-bit) with USB cameras from various vendors, none of them work.

The symptom is: the program started fine, and the camera would be activated for a second and then it immediately went off.

There is no apparent error on the console, until you open http://localhost:56000/mjpeg, when it will start to throw 2019/04/24 14:34:28 mjpeg: read: camera: can not retrieve frame: EOF errors constantly.

The "cam2ip-1.5-64bit-cv2.zip" version works flawlessly.

It is not a big deal to me personally since I can just use CV2 version instead, but think developers may want to know this.

Thanks!

Would be great if cam2ip would support the current OpenCV releases.

So, my laptop's integrated camera works no problem, but the USB webcam I'm trying to setup gives this error:
socket: read: camera: invalid JPEG format: uninitialized Huffman table
And of course, I can't see any image in the browser. Please help.

This can be implemented in the web browser as well, but it will be a bit harder to do so, im only providing a very simple example.

Better bandwidth may be achieved if the jpeg frame being sent is the difference between the previous Matrix and the current matrix we are about to send. This is because for small periods of time, not much in the matrix would change significantly, this means subtracting these matrices would leave a lot of values near zero, this means when we do jpeg compression on this matrix, it is more efficient. If you want more detail you can look up how jpeg and discrete fourier transforms work.

Unfortunately I am unfamiliar with the opencv interface for go lang but here is an implementation in c++. If you do implement this the client will have to change as well, it will have to add the incoming matrix to the previous matrix it received.

As you can see the size of the data to transmit is a lot lower.

Hi there,

I am interested to build this application for android device, I saw you do have android support, however I am having trouble to build it. Can you please kindly share the build steps for the android build?

Thanks.

Using a Logitech webcam I'm getting:

2019/10/05 14:23:49 jpeg: read: camera: invalid JPEG format: uninitialized Huffman table

I'm guessing this is a similar problem to this fix:

blackjack/webcam#7 (comment)

Installed "cam2ip" on a Raspberry Pi version 2 and got the following when executing.

$ cam2ip
cam2ip: /usr/lib/arm-linux-gnueabihf/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by cam2ip)
cam2ip: /usr/lib/arm-linux-gnueabihf/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by cam2ip)

I get exactly the same messages when executing the version for Raspberry Pi v3 on the4 v2 platform

I just installed cam2ip on my RPI B3+ and it works well.
My RPI has static IP 192.168.0.60
MJPEG works perfectly when I connect here : http://192.168.0.60:56000/mjpeg

But HTML doesn't work when connecting to http://192.168.0.60:56000/html
I'm connecting from a remote computer on the network
But the javascript code wants to open websocket 127.0.0.1
"WebSocket connection to 'ws://127.0.0.1:56000/socket' failed: Error in connection establishment:net::ERR_CONNECTION_REFUSED"

It should open ws://192.168.0.60:56000

Am I doing something wrong ?

Can put a option to display videos like webcam?

Hello again,

I am using cam2ip instead of motion because motion is using to much CPU all the time, and I love Go by the way. I am using it inside a Docker container. Could be nice to provide it officially no ?

Below the Dockerfile that I am using right now. It could be improved by using alpine and environment variables for example.

Hi

win 10
downloaded 64 bit version
double clicked on it from the winrar window
web cam is plugged
it asks for the firewall to allow access, I click yess
no matter what I choose in the web browser, it keeps giving me that error

When we try to open 3th camera we got:
camera: cannot open camera XX
All cameras are working when running 1 or 2 instances.
We use windows x64 (opencv_ffmpeg2413_64.dll). We use different ports and indexes.

Hi,

I get an error when compiling on windows 10.

libjpeg-turbo installed
libjpeg-turbo-2.0.0-gcc.exe
path:

I have no idea what's wrong, please help

Please add a license to your project. Without one it is legally questionable to work with your code. I recommend ISC for permissive license, or AGPL for a copyleft license.

i had followed all the steps mentioned for Source Code Compile
i had installed following things

1. go1.11.windows-amd64.msi
   GOPATH: %USERPROFILE%\go

2. libjpeg-turbo-2.0.0-gcc.exe

and while trying to compile im getting the error below attached let me know how can i compile successfully

This is a fantastic tool! It would work better for my case if it if it did not grab the camera as soon as the server is started, but instead only when it is actively serving video or images. This might result in some lag time when starting up, but this would not be a problem for me. Leaving the camera off when the server is not in use would be helpful.

Not familiar with go or opencv, but it looks that the camera is initialized in New()

Not sure but maybe that initialization could be deferred? Possibly to Read() ?? Or maybe done by the handlers? (JPEG would release immediately; MJPEG or HTTP would release when the connection is closed)

Hi. I've used this software for a while and it does a nice job with my cheap logitech C270 webcam, thanks. However, cpu usage for cam2ip is always at the top.

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

7158 rolf 20 0 824140 41904 13576 S 85.2 0.3 5902:38 cam2ip

This looks to be spread pretty evenly across the 4 cores, according to htop. A bit earlier this a.m., CPU was more like 75%, maybe due to lower light levels? I am viewing the stream in Chrome at fullscreen, typically, and it's been running well for about 4 days, this session. That's much better than when I was using vlc to view the v4l2 device, which would crash frequently, requiring re-starts/re-plugs of the usb cable. Kudos!

Following are some bits on the hardware and the command I use to start cam2ip. I wonder if you have any thoughts? Thanks.

Could it be set up to handle more than 1 connection to the same camera? I was trying to set up online feed with my web cam, and every time I open second connection it shows gray frames with the following messages

What is the format for the password file login name and password?

Hello,
I would ask for an instruction how to change resolution under Windows OS?

If a computer has multiple cameras (virtual or physical), it can be hard to identify the camera by an index number. Perhaps enumerating the camera index and which camera it is in a command switch would be useful. In addition, allowing you to select a camera by name would be good for times when the index may change from time to time.

On a mac:

../../antonini/golibjpegturbo/decode.go:32:10: fatal error: 'jpeglib.h' file not found
#include <jpeglib.h>

I get an import error related to base64 from goost namespace. It seems goost.org does not work. Wouldn't it be better using the standard base64? I have a fork with the fix if interested.

go get goost.org/encoding/base64 
go get: unrecognized import path "goost.org/encoding/base64": https fetch: Get "https://goost.org/encoding/base64?go-get=1": dial tcp: lookup goost.org on 172.25.192.1:53: no such host

If not, is there a workaround for this?

I know this is not an issue I'm just new to this and a bit slow. Can't find an answer anywhere else. How can I change via command line which camera is used? Or is it compiling the program where I can change that? Im just downloading the binaries which works great but use the internal webcam. Thank you for your time.

I tried the precompiled for Mac OS. It works but randomly crashes after a few minutes.

Greetings. I have a Windows 10 system with two 1080p webcams connected to it running cam2ip for both cameras. The cameras support up to 30FPS at 1080p, but cam2ip will not run them at any higher than 5FPS no matter what value I use for the -delay option. I don't need to run them at the full 30FPS, but I'd like to be able to run them at at least 10FPS. Is there an additional setting I'm overlooking?

Thank you.

When I try to install using go get -v -tags cv2 github.com/gen2brain/cam2ip/cmd/cam2ip I get the following:

# pkg-config --cflags  -- opencv
Package opencv was not found in the pkg-config search path.

When I do go get -v github.com/gen2brain/cam2ip/cmd/cam2ip I get the same without the opencv issue.

When I run one of the binaries offered, I get -bash: ./cam2ip: No such file or directory except for if I use the rpi static version which seems to work. However, when running that version it would seem that the frame rate is very slow.

For some context, this is the system I am working with

Any help you can offer, I would appreciate. Thank you in advance.

as stated above, when we try to access the same camera on 2 different devices, the video stream lags a lot, or one of the devices straight up shows no output.

Hello,

Nice software ! That could be nice to add an option to rotate (90 / 180 / 270) the image.
What do you think ?

Just as it is stated above. Will there be any new release static builds? There seem to be some commits from the last release binary uptil now. Just curious to know.

Edit: ty for your work on cam2ip tis very helpful :>

Currently when I run the program I go through a series of indexes until I find the right camera on my mac.
-index 1, 2, 3 etc

It would be nice if we could call the camera by its Unique ID.
Example:
Unique ID: 0x4015000005ac1112

Also, it would be even better if the program would tell us what those Unique Ids are (on our system)

Full Example

1. Start the program by running it via index
   /Users/bronzemedia/Downloads/cam2ip -index 2 -bind-addr ":4444" -width 1920 -height 1080

2. The system responds with:

_Listening on. :4444
CameraID.     : 0x4015000005ac1112_  

3. Then next time we can call it like this:
   /Users/bronzemedia/Downloads/cam2ip -cameraid "0x4015000005ac1112" -bind-addr ":4444" -width 1920 -height 1080

Great project.

However, running on browser without streaming support will exhaust memory pretty soon. Its great if you only want to peek every now and then, but to keep it live for a long time is not an option.

Hello

I have a problem with cam2ip.
When I run it gives me the answer camera: no camera at index 0
webcam visible through lsusb and support uvc:

I also tried using -index 1(2,3,4,5...) but it gave no result.
I tried to plug the webcam into other USB ports, but it did not help.

Hello,

I am facing this issue with last version : /lib/arm-linux-gnueabihf/libc.so.6: version 'GLIBC_2.27' not found
Do you know where it could come from please ?

Thanks
