Hi there,

It wasn't too hard to figure out in the end, but perhaps it would be useful to document (unless I missed it) what dependencies need to be installed before compilation will be possible?

On raspbian, I had to install libasound2-dev, libopus-dev and libortp-dev.

Hello, I also noticed the libasound2-doc is needed. So far I had to issue: sudo apt-get install libasound2-dev libopus-dev libortp-dev libasound2-doc then sudo make and sudo make install to complete the installing procedure. My platform is RPI3 with jessie

Thanks. What version of distributive is that?

By the way, I tried to send the signal over my network, using two RPI 3 connected over wi-fi , but the sound is very distorted. I tried to connect the two RPIs using cables and disabling wi-fi, same result: sound is very choppy and distorted. I tried different combinations of frames, periods, jitter buffer with no luck. Any suggestions?

I get pretty good results for sending audio from an RPI 2 playing a video file using omxplayer to a Debian desktop with better sound than the TV connected to the RPI. The sound was indeed choppy and distorted with buffer time 2 ms, but with 64 ms it improved enormously over my WiFi network, and the lip-sync is still OK.

Thanks! I will give it a try, although for my design I still need to use the RPI with soundcard as source.

Cheers, Andrea

Perhaps you could try a test with an mkv or mp4, or even a .wav first? After following the instructions given by Mark (and the tips here on dependencies) I ran "tx -d hubcap -m 64 ... &" and then "omxplayer -o alsa ..." which gave something like 30-40% load on my RPI2. By the way, I am using Raspbian Stretch, and kernel 4.14.18-v7+ #1093 SMP Fri Feb 9 15:33:07 GMT 2018 armv7l. I have no pulseaudio or jack and I run direct from the console.

Hello,

thank you for the heads up. I had to put this project on hold due to my work schedule but I will jump back on it as soon as possible. I want to get this thing done :)

Cheers, -Andrea

Hey this works for playback but then segfaults after 10 seconds or so on rx yet tx works fine any ideas?
