Summary: mpeg2dec does not cope if downstream buffer allocation
has stride != width
Classification: Platform
Product: GStreamer
Version: git master
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins-ugly
AssignedTo: gstreamer-bugs at lists.freedesktop.org
ReportedBy: simon at farnz.org.uk
QAContact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
mpeg2dec assumes that stride == width. This causes corrupt video with:
gst-launch-1.0 filesrc location=file.ts ! tsdemux ! mpegvideoparse ! mpeg2dec
! vaapisink
(or any other sink where stride != width)
I've got a patch I'll attach to fix this, which also asserts that the stride is
something libmpeg2 can cope with.
