ffdec_mpeg4 and xviddec from git doesn't play MPEG-4 video in 1280x1024.
At the same time they play video in 640x480 from the same source.
The stream I get from IP-camera and save to file with the following pipeline:
gst-launch-0.10 -v --gst-plugin-path=/home/user/bin/gstreamer/lib udpsrc
uri=udp://127.0.0.1:4951 caps="video/mpeg, mpegversion=4" ! gdppay ! filesink
location=rec_1280.gdp

Then I tried to play video with the following pipeline:

gst-launch-0.10 -v --gst-plugin-path=/home/user/bin/gstreamer/lib filesrc
location=~/rec_1280.gdp ! gdpdepay ! ffdec_mpeg4 ! xvimagesink
gst-launch-0.10 -v --gst-plugin-path=/home/user/bin/gstreamer/lib filesrc
location=rec_1280.gdp ! gdpdepay ! mpeg4videoparse ! ffdec_mpeg4 ! xvimagesink
gst-launch-0.10 -v --gst-plugin-path=/home/user/bin/gstreamer/lib filesrc
location=rec_1280.gdp ! gdpdepay ! mpeg4videoparse ! xviddec ! xvimagesink

In attachement I include both files with resolution 1280x1024 and 640x480 so
you can compare.
