*Adjusted description so as not to show as email to non logged in people
Most affected files are   Baseline at L2.1, Baseline at L1.1 *

Those would be the most likely to fail to be decoded but certainly  not limited to kust them.
These files are commonly found online though many users will have locally.
Also affected  other than totem, totem youtube plugin, &  banshee would be the mozilla-plugin & minitube.
Typically the audio will play with no video though sometimes neither

*Moving libgstvideoparsersbad.so to a .bak allows decoding to take place
on the previously affected files, but *is not the recommended fix*

Upstream has provided a commit to fix in both gstreamer 1.0 & .10 (gst-plugins-bad0.10.23
Attached below is a patch taken from the 0.10.23 commit to be applied to 0.10.22 that's currently used in 12.04

Also attached is a cut small sample file, noting the file plays fine in all non gstreamer players & in all gstreamer players in 11.10 & earlier
The file should be playable in totem, banshee & firefox with totem-mozilla plugin installed but only audio is decoded
