A NOOB here... I'm using this to create a FM Transmitter on my RPI 3: https://github.com/markondej/fm_transmitterIt works well, but I'm trying to stream my internet radio station to the FM Transmit.I tried using MPlayermplayer -cache 8192  -af format=s16le resample=22050   http://demo.out.airtime.pro:8000/demo_1 | sudo ./fm_transmitter -f 99.0 -I've tried to write the stream to a file and then read it with mplayer -ao pcm:file=audio.wav http://demo.out.airtime.pro:8000/demo_1 | sudo ./fm_transmitter -f 99.0 -r audio.wavBut that doesn't work.Maybe I'm on the right track, maybe not.Is this possible?In the read me for the fm_transmitter the way a USB sound card is read is arecord -D hw:1,0 -c1 -d 0 -r 22050 -f S16_LE | sudo ./fm_transmitter -f 100.6 -So my thinking is if the sound card stream can be read surely a HTTP stream can be read using ./fm_transmitter.Not sure if this is more related to the capabilities of ./fm_transmitter or if there's some trick in linux that could do this.Any advice would be well received.
