[Bug 790000] rtph264depay: doesn't update resolution if format is avc

[GStreamer (GNOME Bugzilla)]

--- Comment #7 from Justin J. Kim <justin.joy.9to5 at gmail.com> ---
I printed log of old_s(gstrtph264depay.c:419) and tmp_s(gstrtph264depay.c:420)
to see what happens while playing the above pipeline.

```

```

The other properties except for codec_data are same so if codec_data is ignored
by gstrtph264depay.c:421, caps will not be updated. 

https://cgit.freedesktop.org/gstreamer/gst-plugins-good/tree/gst/rtp/gstrtph264depay.c?id=e7e7f262009852a8515fa6db336138b61a4c3aef#n421

This causes the situation that `h264parse` can't recognize changes.

If sending codec_data, the case of #782949 seems to work, too.
