then, getting decoder's compliance test changes a bit to :
```
Buffer ioctls:
		fail: v4l2-test-buffers.cpp(607): q.reqbufs(node, 1)
	test VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF: FAIL
		fail: v4l2-test-buffers.cpp(783): VIDIOC_EXPBUF is supported, but the V4L2_MEMORY_MMAP support is missing or malfunctioning.
		fail: v4l2-test-buffers.cpp(784): VIDIOC_EXPBUF is supported, but the V4L2_MEMORY_MMAP support is missing, probably due to earlier failing format tests.
	test VIDIOC_EXPBUF: OK (Not Supported)
	test Requests: OK (Not Supported)

Total for qcom-venus device /dev/video1: 45, Succeeded: 40, Failed: 5, Warnings: 0
