Summary: Crash in theoradec when using uridecodebin and
filtered caps
Classification: Platform
Product: GStreamer
Version: git
OS/Version: Linux
Status: NEW
Severity: major
Priority: Normal
Component: gstreamer (core)
AssignedTo: gstreamer-bugs at lists.freedesktop.org
ReportedBy: vincent.penquerch at collabora.co.uk
QAContact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
It seems the pad alloc gets us a 0 byte buffer when we asked for a frame sized
one, and the memcpy overwrites what should not be overwritten.
Repro command line:
gst-launch-0.10 uridecodebin uri=file://wherever ! 'video/x-raw-yuv' !
ffmpegcolorspace ! 'video/x-raw-rgb' ! ximagesink

capsfilter: don't assume _get_caps still has to be
_set_caps only gets called when the buffer is actually pushed, so there
is a reasonably big window between when the initial caps are retrieved
and when the caps are set on our src pad. So we can't assume the not
having negotiated caps on our src pad means _get_caps still has to be
called.
Instead simply always suggest the new caps on buffer_alloc.
(or at least that's what git bisect points to).
