  RPI4 Cross Compile for libcamera-app on Mac Pro (with docker) (3): Setup toolchain Why am I doing this After reading the  camera app instructions , I thought of starting the development by modifying the libcamera-apps. Therefore, the first step is to build the original repo; after that, I can add my stuff to the official standard version. It looks easy. The  code-building instructions  are well-documented on the official website, but there is a catch in my mind. I bought an expensive, neat, and tidy Macbook Pro after quitting my job as a mind-comforting geek gadget to compensate for losing my working life, so I don't want to build the code on a small RPI board. Instead, I want to build the code and develop things on my new laptop, which is why I got into this over tons of unexpected things just popping up in my sight… Preface Create a docker container where I can cross-compile the libcamera-apps. Setup chroot Setup toolchain <- Build libcamera-apps The docker container should

 RPI camera → website → Chromecast → TV: (2) Streaming the video to TV Why am I doing this? As an unemployed engineer, I need to find interesting things to fill my leisure time. I found there is a thing I can do to make my life more convenient to see the toys under my couch without in the crowing position of bending my knee and waist to find the toys which are "eaten by the couch," my kids said. Maybe I can use a camera on RPI to see the area under the couch and project the streaming video onto the TV by Chromecast. That is my initial thought. Devices An RPI4 A V2 camera My computer that I can run a server on. A Chromecast and TV Goal Streaming the video to TV From the previous post , I can stream camera data from RPI to my computer; this time, I need to project the camera data to my TV. There are many ways to send the video to TV. My initial thoughts are that if I can write a website to show videos, I can project the webpage using the browser's built-in button, and all t
