Summary: GStreamer no longer plays Vorbis streams with
incorrectly framed headers
Classification: Platform
Product: GStreamer
Version: 1.12.1
OS: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: gst-plugins-base

GNOME version: ---
After a recent update (probably from GStreamer 1.12.0 to 1.12.1)
GStreamer-based media players no longer play many of my Ogg Vorbis files. For
example:
$ gst-play-1.0 "./Amazing Blondel/Evensong/Amazing Blondel - 10 - Under The
Greenwood Tree.ogg"
Press 'k' to see a list of keyboard shortcuts.

I suppose that if the Vorbis files aren't to spec, then technically it's OK for
GStreamer to fail. But it had been playing them perfectly and without
complaint for the last 15 years, so it's a bit annoying that it's suddenly
refusing to play them now. (Especially since it turns out that hundreds of my
Vorbis files have been corrupted in this way -- I am guessing that this is or
was another bug in EasyTAG, similar to Bug 776110.)
Is there any chance that the old behaviour could be restored, so that GStreamer
at least *attempts* to play the Vorbis files rather than failing outright?
