Raspberry Pi arm64 potential fix

[MattiKemp]

For those having trouble getting their camera to work with newer Raspberry Pis (works on Ubuntu 20.04), try this:

install mjpg-streamer dependencies

sudo apt-get update sudo apt-get install cmake libjpeg8-dev sudo apt-get update
install aarch64 gcc and g++ for userland

sudo apt-get install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu sudo apt-get update

Thanks to https://github.com/waveform80/picamera/issues/540#issuecomment-881645216:

download userland

git clone https://github.com/raspberrypi/userland cd userland git revert f97b1af1b3e653f9da2c1a3643479bfd469e3b74

press ctrl+o, enter, crtl+x, and enter

git revert e31da99739927e87707b2e1bc978e75653706b9c

press ctrl+o, enter, crtl+x, and enter

Fix /interface/mmal/CMakeLists.txt

sed '/^target_link_libraries(mmal mmal_core mmal_util mmal_vc_client vcos mmal_components)*/i SET(CMAKE_SHARED_LINKER_FLAGS "-Wl,--no-as-needed")' ./interface/mmal/CMakeLists.txt > ./interface/mmal/CMakeLists-temp.txt mv ./interface/mmal/CMakeLists-temp.txt ./interface/mmal/CMakeLists.txt

Build userland

sudo ./buildme --aarch64

Copy userland libraries

sudo cp /opt/vc/lib/*.so /usr/lib/aarch64-linux-gnu/ cd ..

Build and install mjpg-streamer

git clone https://github.com/jacksonliam/mjpg-streamer.git cd mjpg-streamer cd mjpg-streamer-experimental make distclean make CMAKE_BUILD_TYPE=Debug sudo make install

Check if your camera is detect and enabled

vcgencmd get_camera

This should return: supported=1 detected=1 If it doesn't:

sudo vim /boot/firmware/config.txt

and add start_x=1 to the very end of the file, save, then reboot.

If you eventually get: supported=1 detected=1, return to the /mjpg-streamer/mjpg-streamer-experimental/ directory, and try:

sudo chmod +x ./start.sh ./start.sh

If that doesn't work, while you are still in /mjpg-streamer/mjpg-streamer-experimental/:

export LD_LIBRARY_PATH="$(pwd)" ./mjpg_streamer -i "input_uvc.so -y -r 1280x720 -f 20" -o "output_http.so -wpwd./www"

This is the only thing that got it working for me on a Raspberry Pi 4b running arm64 Ubuntu (20.04). I hope something in this mess may help you.

Thank you very much! It works. All the userland libraries disappeared before...

It really help me, thanks for your contributing, I'm confused for this problem been 2 days.

Here I'll attach some output from terminal.
