Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.
brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus
I faced with the same problem on Ubuntu 16.04 and angular CLI 1.0.0-beta.30 | |
The problem was related with Inotify Watches Limit on Linux. | |
To solve to issue I increased the watches limit to 512K | |
sudo sysctl fs.inotify.max_user_watches=524288 | |
sudo sysctl -p --system | |
After that I restarted my IDE (WebStorm in my case) and after that the change detection started to work. | |
