Sounds interesting but is wrong. See attached samples.

It seemed to work before I updated gst-libav to cb9e40ff4c78014a336b77bd2b142e12758106ef, but I might be wrong.

Transcoding was done like in example attached to bug 689398

Comment 2 Sebastian Dröge (slomo) 2012-12-17 12:57:57 UTC 
This works fine here:
gst-launch-1.0 audiotestsrc ! vorbisenc ! vorbisdec ! avenc_wmav2 ! avdec_wmav2 ! pulsesink

Could you attach a testcase for this?
Comment 3 Jens Georg 2012-12-17 14:03:18 UTC 
Just take https://bugzilla.gnome.org/attachment.cgi?id=230368
Comment 4 Jens Georg 2013-01-10 10:33:44 UTC 
Testcase linked
Comment 5 Jens Georg 2013-05-13 16:32:50 UTC 
Did I mention that this used to work with 0.10?
Comment 6 Tim-Philipp Müller 2013-05-13 17:09:30 UTC 
This works fine for me in git master, git 1.0 branch, and 1.0.5 with:

   gst-launch-1.0 -v asfmux name=mux ! filesink location=foo.wmv  \
       uridecodebin uri=file:///home/tpm/690130.webm name=d  \
        d. ! queue ! videoconvert ! avenc_wmv2 ! mux.  \
        d. ! queue ! audioconvert ! avenc_wmav2 ! mux.

Does this work for you with latest git master of everything and/or latest 1.0 branch of everything?
Comment 7 Jens Georg 2013-05-15 08:20:29 UTC 
Yes it does, but did you try the encodebin sample linked from comment 3?
Comment 8 Jens Georg 2014-08-10 19:26:02 UTC 
Tested with 1.4, I still get broken audio when using encodebin-based sample from attachment 230368 [details]
