[Bug 779524] buffer with video meta information do not support memory split buffers

[GStreamer (GNOME Bugzilla)]

https://bugzilla.gnome.org/show_bug.cgi?id=779524

--- Comment #11 from Christophe Fergeau <cfergeau at redhat.com> ---
Just to make things clear (they weren't for me when reading this bug report).
What Frediano is trying to use is a GstBuffer containing several chunks, each
chunk contains N * stride bytes (N is potentially different between each
chunk), with offset/stride metada attached to that buffer. What then happens is
some display corruption as GStreamer only try to use the first chunk, and does
some out of bounds reads on that chunk (as it assumes it's aligned on a plane
boundary?)

Is your « We could validate and warn if the remaining memory space is too small
» suggestion aimed at fixing this buffer overflow?
