and it is open source, but under a somewhat cumbersome license. For this
reason, most distributions do not compile FFmpeg with the FDK-AAC codec,
There are many more parameters, in particular “--x264-bitrate” to control

A particular note about the MP4 mux: If you plan to stream for long periods
continuously (more than about 12–24 hours), the 32-bit timestamps may wrap
