Cannot install using go get #45

Open MaddyPhi opened 1 year ago

MaddyPhi commented 1 year ago

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.
Perhaps you should add the directory containing 'opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found

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

The camera appears twice as /dev/video files. That confuses cam2ip. I have an internal UVC camera and the external, so 4 `/dev/video` files in total.

While the first device of a pair cannot be used by guvcview it must be used by cam2ip. But I only get 640x480 resulution.

From another shell I can run:

$ mpv http://127.0.0.1:56000/mjpeg --fps=25 --fs

OK, the issue with only 640x480 resolution is selected also happens if I access the device directly. No idea how to ask for higher resolution.

gen2brain commented 8 months ago

I changed recently the default to be internal native jpeg, and not libturbo-jpeg. That is slower but I cannot handle the issues people who don't know how to compile are sending. Also, every cam has resolution, if the cam is 640x, you cannot "request" higher, you need to get better camera. Of course, you can do software scale.

mmokrejs commented 8 months ago

@gen2brain Thank you for your answer.

I discovered https://github.com/jacksonliam/mjpg-streamer meanwhile:

I read a bit the code because the README.md were not detailed enough to give me a clue how to handle the tool. I suggest showing more complicated examples:

# when neither -u nor -y are specified then  JPEG aka yuvj422p is selected by default
# --uyvy or -u specify UYVY aka yuvj422p
# --yuv or -y specify YUYV aka yuv420p (my mobile app cannot read the MJPEG stream but mpv works fine)

Then I could access both instances with my camera 2 and 3 (camera 0 is laptops internal, yet another UVC):

mpv http://192.168.0.45:8080/?action=stream
mpv http://192.168.0.45:8888/?action=stream

I did not manage to use the --fourcc RGB565 or --fourcc RGB24 for some reason. Also not setup UDP streaming server or RTSP server.

Thanks, but that all seems to be related to mjpg_streeamer app, right? I just heard about it. Readme should have just basic info imo, the rest is up to user.

Yes, this about mjpg_streeamer app, which allows me to select even the maximum resolution of my camera.

If you can, please send a PR for readme, where ffplay and vlc are, but just one example please.
