gstreamer basic command line reminder
I recently wanted to record an audio stream. I tried audacity which somehow stopped recording after a while and then found mhwaveedit which did the job. However, i though to myself, how do i do it without GUI?
Gstreamer to the rescue! After examining man gst-launch-0.10 i found the following options.
1. Play a sound:
a: gst-launch-0.10 playbin uri=’file:///mnt/audio/1.mp3′
b: gst-launch-0.10 filesrc location=’1.ogg’ ! decodebin ! alsasink
2. record sound from the sound card
mp3: gst-launch-0.10 alsasrc ! audioconvert ! lame ! filesink location=input.mp3
ogg: gst-launch-0.10 alsasrc ! audioconvert ! vorbisenc ! oggmux ! filesink location=input.ogg
It looks like the library is very versatile but i did not found a good tutorial how to build these command line pipes.
