How to enable dma buffer output for Gstreamer plugin omxh264dec

Hi, All

 

I used gstreamer to make below pipline:

filesrc location=video.mp4 ! qtdemux ! h264parse ! omxh264dec ! appsink name=testsink

 

But when i pull the buffer in appsink, I found it is not dma buffer, that means I can't input this buffer directly into  my accelerator in PL side.

 

How can I get the dmabuffer after omxh264dec in appsink.

 

I saw one message before said set omxh264dec op-mode = 1 can output dma buffer, but it not work on my board.

 

Thanks!
