ecore_audio: Add an example - a simple CLI music player
Give it sound files (ogg, wav, not mp3) as parameter or "tone:freq=<f>,duration=<dur_in_s>" to play a lovely sine wave * '<' and '>' seek forward and backward * '+' and '-' change the volume * Space toggles pause * Shows information for the song (remaining, %) * (Un)loop a song with 'l' * 'n' - Next song * 'm' - Next song simultaneous to current * Volume can be set from 0 - 150% Signed-off-by: Daniel Willmann <d.willmann@samsung.com> SVN revision: 81001
