Not getting input_raspicam when compiling on 64bit raspbian

[xamindar]

This doesn't seem to be compiling everything when I try on 64 but Raspbian. I am not seeing any errors either.

Have you tried running make distclean first?

[xamindar]

Yes I have, but it doesn't work. "make clean" works:

pi@raspberrypi4:~/mjpg-streamer/mjpg-streamer-experimental $ make distclean make: *** No rule to make target 'distclean'. Stop.

[xamindar]

I also pulled down a fresh repo and still does not build that file: Is it possible any of the following are not really optional as it says?

-- The following OPTIONAL packages have not been found:

• OpenCV
• Gphoto2
• SDL

OK, here we go, but not sure what it needs:

• PLUGIN_INPUT_RASPICAM, Raspberry Pi input camera plugin (unmet dependencies)

[xamindar]

OK, it looks like this package looks for includes in a non-standard location. I got it to build by working around with a symlink: ln -s /usr/include /opt/vc/ ln -s /usr/lib/aarch64-linux-gnu /opt/vc/lib

This is mentioned here: https://www.raspberrypi.org/forums/viewtopic.php?t=275370 "2) libraspberrypi0, libraspberrypi-dev and libraspberrypi-doc have been moved out of /opt/vc/ and into /usr/ instead (making it more standard). Any code built against these libraries will require changing to refer to a more standard location (/usr/lib/ rather than /opt/vc/lib)"

It looks like it builds, but when run, it just segfaults.

[jacksonliam]

Thanks that's useful info.

It might be that the headers we have had to include in this repo to build against mmal need updating for 64 bit.

I assume the other, non input_raspicam modules work? You can test out input_uvc wih a raspi cam by running

modprobe bcm2835-v4l

[xamindar]

I posted about it in the pi forums and someone said mmal is not yet working on 64bit raspbian. So I guess that's that.

I wasn't aware you could use input_uvc, thanks. However, I was unable to get that to work. When I try, i just get a constant scroll of "Ignoring empty buffer ..." going down the screen.

Looking in to it further, I was able to successfully capture an image using the v4l2-ctl command. So I know the camera does work.

[jacksonliam]

OK thanks for the info. Sounds like the part of bcm2835-v4l we need isnt working either, if it's just delivering empty buffers. Even if v4l2-ctl is able to create an image.

[gulbrillo]

Hey :) I'm running into the same issues. So far, getting the latest and greatest Pi was a big mistake. ^^ I edited plugins/input_raspicam/CMakeLists.txt to make it compile. But it segmentation faults. (mmal issue?) Do we have to wait until the 64 bit framework is available? or did someone find a workaround? Thanks all!! :)

[guysoft]

Any news on this?

[jacksonliam]

@guysoft I can't really do anything about input-raspicam until MMAL is supported on the 64-bit OS which I don't think it is yet?

I believe mjpg-streamer build correctly detects this and does not build the plugin. So no errors or failures to build are seen as far as I know?

V4L2 using the input-uvc plugin and the raspberry pi cam v4l2 driver should still work IIRC? I believe it is out of the box on your 0.18 RC1.

Cheers!

[esmaeilpour]

Came across this and guess might be helpful https://github.com/jacksonliam/mjpg-streamer/issues/203#issuecomment-484513852

[guysoft]

According to @esmaeilpour simply installing libraspberrypi-dev package should make it compile.

Probably pulling in the headers will compile the plugin but I believe it still won't work at runtime on 64 bit.

libraspberrypi-dev

Did not help.

[nymda]

any update on this? im also not getting input_raspicam

[mcr222]

just want to leave a note here in case anybody ends up here. Even for 32 bit it does not build input_raspicam.so because of the moving of the libraries.

The easiest way to solve this is by just modifying the CMakeLists.txt from mjpg-streamer/mjpg-streamer-experimental/plugins/input_raspicam and change all paths "opt/vc" for "usr".

[lukeallister]

I found this issue when trying to use 'input_raspicam'. I can confirm that input-uvc does work instead on the 64bit raspberry pi os:

mjpg_streamer -o “output_http.so -w ./www” -i “input_uvc.so -rot 180 -r 1280×720 -fps 15”

I am on a 32-bit OS, and creating a symbolic link with sudo ln -s /usr /opt/vc following by a make distclean works for me. Seems that somehow the include path has changed.

I'm getting compiler warnings when I compile the input_raspicam plugin after making this symlink, however the raspicam plugin seems to be running normally! Just for context/knowledge, why is there a discrepancy in the headers between what's expected, and what is installed on Raspbian?

[Mactarvish]

sudo apt-get install libraspberrypi-dev That works!

Note that I'm on 4B+ with Linux ubuntu 5.4.0-1069-raspi #79-Ubuntu SMP PREEMPT Thu Aug 18 18:15:22 UTC 2022 aarch64 aarch64 aarch64 GNU/Linux instead of original rasberry system, current system can be downloaded in official website.
