options for non-gui audio streaming RTP mp2 decode and play
« on: August 09, 2011, 11:32:00 AM »
I am currently streaming mic audio to a box with vlc to receive the stream. It works nicely, only thing was ffmeg seems to be compiled without mp3 lame option, thus mp2 codec.

ffmpeg -f oss -i /dev/dsp -acodec mp2 -ab 32k -ac 1 -re -f rtp rtp://192.168.1.70:1234



Any ideas about options from the tiny core apps to decode the mp2 rtp stream and feed it to the headphone socket?

I am looking for a command line, pipe style, hard coded solution. Small footprint to fit in a thin client 64M DOM if possible.

Hi hca
You mentioned  vlc  and  ffmpeg, did you install  lame.tcz?

Hi Rich,

yes had lame installed, but lame or libmp3lame in the acodec option cause an exit from ffmpeg with "unknown encoder". I read somewhere while searching around this can be because it was not enabled in options while compiling.

I have never played with audio streaming so this is new ground, but mp2 works ok.


Vlc headless might be nice but it might be a bit much for a 64meg DOM.

Hi hca
Just thought I'd state the obvious, you'll have to wait for one of the extension maintainers or someone
familiar with the program to help you.

Mplayer?
