1 | /* |
2 | * Starts the AirPlay server (name "FakePort") and dumps the received contents | |
3 | * to files: | |
4 | * - audio.pcm : decoded audio content | |
5 | * - metadata.bin : meta data | |
6 | * - covertart.jpg : cover art | |
7 | * | |
8 | * Requires avahi-daemon to run. Also requires file "airplay.key" in the same directory. | |
9 | * | |
10 | * Compile with: gcc -o example -g -I../../include/shairplay example.c -lshairplay | |
