gstreamer playback pipeline Internal data flow error on DM3530 EVM

Hi,
We are a small video startup company in Seattle and we are using TI's DM3530 to do video encoding (using TI's open source with gstreamer and H.264 encode engine). I read a lot of your expert article and would like to ask you a question we run into while trying to do video playback and decoding via network. Here is the setting:
1. We have a DM3530 dev board to do live encoding with gstreamer with H.264.
2. We could receive the stream and decode OK while running a open source gstreamer with ffmpeg plugin (for decoding H.264) on X86 platform, but,
3. When we port that gstreamer open source (either from gstreamer's official web or from TI's Wiki web), with corresponding ffmpeg (v1.0.13) on DM3530 (another dev board) to be a playback board, it always has data error which comes out from our ported ffmpeg plug-in for gstreamer. But the same plugin works just fine on X86 platform. 
thanks a lot,
alan,
