Add video encoder plugin using hardware MPEG4 codec on DM355

Hi , guys.

I  tried the gstreamer provided by  Bernie Thompson several days ago.

 The avi decoder works perfectly in the Gstreamer.

The work I want to do is to add a video encoder plugin in the gstreamer.

So, I changed the libce.cfg first.

I add the mpeg4enc to the GstEngine list.

Then I recompiled and installed the libce.

But when I run the video decoder, I got the following messages:

(gst-launch-0.10:1211): GStreamer-WARNING **: Failed to load plugin '/usr/local/lib/gstreamer-0.10/libgstdm3xx.so': /usr/local/lib/libce.so: undefined symbol: ceil

I did not make any other chang at all.

These messages  confused me .

Has anyone met similar problems ?

    I am afraid I am not familiar enough with Gstreamer to help; FYI, since gstreamer is an open source tool, we have done some work to port it to some of our platforms (including DM355 EVM), but this is mostly supported by the Linux community.  In fact, the more robust gstreamer port I have mentioned in other posts will be hosted in GForge and will be supported by the open source community.
