Bug ID: 760550
Summary: wrong/misleading error message from gst-launch
Classification: Platform
Product: GStreamer
Version: git master
OS: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: gstreamer (core)
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: ensonic at sonicpulse.de
QA Contact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
I want to convert an audio file to raw:
gst-launch-1.0 filesrc location=foo.wav ! wavparse ! audioconvert !
"audio/x-raw,channels=1,rate=44100,format=S16" ! filesink location=foo.raw
The mistake above is that S16 is not a valid format, it should be e.g. S16LE.
What gst-launch prints is
"WARNING: erroneous pipeline: could not link audioconvert0 to filesink0"
This is very unfortunate and misleading, since filesink takes any caps. I think
we are missing some error handling and this disguises the root cause.
