Goal: Stream microphone input (using Daffodil USB sound) 24/7 to another box, using ffmpeg (ad even ssh if possible without ffserver (shows to lag alot)
Tutorial which has guided me so far: http://ubuntuforums.org/showthread.php?t=1544946
- I'm not clear how the RTP part works as i tried connecting with vlc from another box and it didn't work.
- I'd like for my Raspberry Pi to transmit audio to another box which will play it live on i's audio out
- Preferably my raspberry would be initiating the connection automatically when eth0 is up, instead of the reverse typical situation where i client connects to a radio station for example.
- Re-connects if internet/power drops.
- Also, is it possible to do this over SSH? (and have the SSH reconnect too?)
So i have ffmpeg and openssh installed on my raspberry, what would I need on the other box aside from OpenSSH to play live to sound card and persistently using what commands?
The ffmpeg part i found resembles this:
ffmpeg -f oss -i /dev/dsp -acodec libmp3lame -ab 32k -ac 1 -re -f rtp rtp://234.5.5.5:1234
but im still not sure how the RTP works exactly. The commands works, but dont know how to connect and from where.
Using this comand (from this tutorial http://mutsuda.com/2012/09/07/raspberry ... ng-device/):
arecord -D plughw:1,0 -f dat | ssh -C user@remoteip aplay -f dat
I was able to play the live audio through SSH, but the audio was choppy and cracking a bit (i know theres issues, i have to correct that).
So basically i want to combine those two commands and do it over a SSH tunnel, and put safeguards for it to reconnect when it goes down. Sorry I wish i had structured this better.
Awaiting a ffmpeg/ssh god to show me the way (exactly preferably) hehe
