rpi 3 support?

[GillesC]

I've tested it on a rpi 3 but I can't seem to make it work, is it because of the used technology, or is it a fault of mine?

[razurac]

Well maybe this will help you:
Did you follow the instructions and installed the additional packages through apt-get?
(Note: ffmpeg isn't anymore in the raspbian repository)

[GillesC]

I did, I've used the instructions on this README to complete all the instructions. I'm currenlty using this repo, but I thought that this repo could provide better quality so I thought why not give it a try ;)

FYI: I don't get any errors when playing a song, there is just no sound in the medium at the specified frequency.

What antenna do you use?

I've just used a small wire that connects with the GPIO 4.

I'm able to transmit FM signals by means of the fm_transmitter repo, but not with this repo.

I am having the same problem.

Since FFMpeg is unavailable from the Debian repo I was forced to complle it from source (which was successful)

I was unable compile PiFMPlay.

Regardless when I issue command to transmit, the program appears to be working, however nothing actually transmits.

> sudo sh pifmplay . 95.9
DEBUG: its a folder!
DEBUG: playfolder
DEBUG: its a file!
DEBUG: playfile
PiFMPlaying: file ./Moby - Porcelain(Atlantic Connection Remix).mp3, frequency 95.9
DEBUG: playmp3
DEBUG: playmp3sox

I was able to successfully use the other FM transmitter repo however it doesn't support mp3 or have as many features as this one https://github.com/somu1795/fm_transmitter

For my antenna I am using a 15" 14AWG solid core copper wire with shielding soldered to a insulated DuPont connector.
@
The other program I receive good results. I really wish II knew how to fix this one though.

I will provide an update if I make progress or fix it.
