creating m4a/m4r files with gst-launch (gstreamer)

Posted on January 1, 2012 by Danielle

Since it’s annoyingly hard to work out what muxer to use for m4a files, and I don’t have a profile for encodebin, here’s the gst-launch command to make m4a or m4r (ringtone) files.

gst-launch filesrc location=input.file ! decodebin2 ! audioconvert ! faac ! ffmux_mp4 ! filesink location=output.m4a

    hi,
    why is it difficult to find out? I’d suggest mp4mux over ffmux_*.
