Hello.

Building ffmpeg.js, a tool I used in my project Device Frame, can be tricky if you need custom filters and encoders. This post details the steps I took to successfully build it on Ubuntu, including installing dependencies, cloning the repo, setting up Emscripten, and running the build. I also included solutions to some common errors encountered during the process.

In a previous post, I discussed screen recording from Android. This post details how I automated the process of adding a device frame to those recordings, making them look more professional. Previously, this was a tedious manual process involving Screenflow, but now I've automated it using ffmpeg. The ffmpeg command scales the screen recording and overlays it onto a background image of a device frame. The code, available on GitHub, handles the entire process, including setting up the Android device for recording, pulling the recording, and applying the frame. While the current solution works well, I'm open to suggestions for improvement from ffmpeg experts.
