Functions

CUresult cuEGLStreamConsumerAcquireFrame (CUeglStreamConnection *conn, CUgraphicsResource *pCudaResource, CUstream *pStream, unsigned int timeout)
Acquire an image frame from the EGLStream with CUDA as a consumer.
CUresult cuEGLStreamConsumerConnect (CUeglStreamConnection *conn, EGLStreamKHR stream)
Connect CUDA to EGLStream as a consumer.
CUresult cuEGLStreamConsumerConnectWithFlags (CUeglStreamConnection *conn, EGLStreamKHR stream, unsigned int flags)
Connect CUDA to EGLStream as a consumer with given flags.
CUresult cuEGLStreamConsumerDisconnect (CUeglStreamConnection *conn)
Disconnect CUDA as a consumer to EGLStream .
CUresult cuEGLStreamConsumerReleaseFrame (CUeglStreamConnection *conn, CUgraphicsResource pCudaResource, CUstream *pStream)
Releases the last frame acquired from the EGLStream.
CUresult cuEGLStreamProducerConnect (CUeglStreamConnection *conn, EGLStreamKHR stream, EGLint width, EGLint height)
Connect CUDA to EGLStream as a producer.
CUresult cuEGLStreamProducerDisconnect (CUeglStreamConnection *conn)
Disconnect CUDA as a producer to EGLStream .
CUresult cuEGLStreamProducerPresentFrame (CUeglStreamConnection *conn, CUeglFrame eglframe, CUstream *pStream)
Present a CUDA eglFrame to the EGLStream with CUDA as a producer.
CUresult cuEGLStreamProducerReturnFrame (CUeglStreamConnection *conn, CUeglFrame *eglframe, CUstream *pStream)
