if it can ,please you tell me how to make? what tool and your framwork do I need for this target?because before I use gstreamer,I search community about this topic. I find websit page:https://devtalk.nvidia.com/default/topic/745883/jetson-tk1/tegra-k1-multiple-simultaneous-video-decoding-encoding-possible-/post/4223784/
but it didnot explain how to do by openmax in detail.please how to decode multiple h.264 video streams simultaneously?
thank you a lot in advance.

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.

does all gstreamer plugins based on NVdia platform has specific documents?I think sometime I can study and research them.in additon how many 720P or 1080P video streams can omxh264dec plugins decode?do you have offical data for this test?
