How Serverless, Puppeteer, FFMPEG, and AWS Lambda can help you get the GIFs from Twitter.
I’ve got an Android project going that uses FFmpeg to build short video files (more on this at a later date). Normally, you run FFmpeg in a terminal window or command prompt. It updates you on the status of a task in that terminal window. I’ve instrumented FFmpeg on Android with some C code and a JNI interface. When I execute FFmpeg from an Android app those status updates are written to logcat.
