Hi,
Please try following pipeline for multiple decoding:

$ gst-launch-1.0 filesrc location=videoplayback.mp4 ! qtdemux ! h264parse ! omxh264dec ! nveglglessink & gst-launch-1.0 filesrc location=videoplayback.mp4 ! qtdemux ! h264parse ! omxh264dec ! nveglglessink &

For more examples, please check

please ask what is the underlying structure of omxh264dec? how to develop gstreamer plugin base on NV chip? do you have gstreamer documents to NV platform? thank you a lot in advance.

Hi,
The link in #2 is the document of gstreamer user guide.
omxh264dec is open source code. You can download it from
https://developer.nvidia.com/embedded/dlc/l4t-Jetson-TK1-gstreamer-1-R21-5
and check the code.
