[gst-devel] Quicktime errors converting m4a to mp3

[Steven Stromer]

Pipeline refuses to preroll, and hangs on the following:

GST_DEBUG="*:2" gst-launch-0.10 filesrc location="song.m4a" ! decodebin
! fakesink


Responds with:

Clearly, m4a decoding is not working here. Minimal references to similar 
errors indicate that this was an issue resolved eons ago. Thus, I list 
my installed packages:

gstreamer.i386 0.10.11-1.fc6
gstreamer-tools.i386 0.10.11-1.fc6
gstreamer-plugins-base.i386 0.10.11-1.fc6
gstreamer-plugins-good.i386 0.10.4-3.fc6
gstreamer-plugins-bad.i386 0.10.3-3.fc6
gstreamer-plugins-ugly.i386 0.10.5-1.fc6.rf
gstreamer-plugins-pulse.i386 0.9.4-4.fc6
gstreamer-plugins-farsight.i386 0.10.2-2.fc6


I have attached a log file that was piped from the above command, with 
more verbose debugging, for review (errors begin around line 7811). I 
really appreciate any help!
