The caps are incomplete in the second example (at least the format is
missing), and in the first you don't provide any at all. But even if
you provide complete caps, you need something that reads exactly one
raw video frame per buffer. filesrc can't do that, see the videparse
element.

You should also consider updating to GStreamer 1.x. The 0.10 version is
no longer maintained since more than 3 years and you're unlikely to get
any support for it anymore.
