aclvdecChannelDescParamType

Data Format	Description
ACL_VDEC_CSC_MATRIX_UINT32 = 0	CSC matrix attribute. For details about the attribute values, see acldvppCscMatrix. The Atlas training product does not support this mode.
ACL_VDEC_OUT_MODE_UINT32 = 1	Frame output mode, to set whether to output frames in real time. The options are as follows: 0: delayed frame output mode. The VDEC starts to output the decoding result only after receiving multiple frames in the stream. 1: real-time frame output mode. The VDEC starts to output the decoding result in real time after obtaining a frame in the stream. Only H.264/H.265 standard streams with simple reference relationships are supported (no long-term reference frames or B-frames).
ACL_VDEC_THREAD_ID_UINT64 = 2	Callback thread ID. NOTE: It is not allowed to pass the same thread ID for subscribing to VDEC callback functions on different devices in the same process. On a single device, the same thread ID can be specified for multiple VDEC channels. Compared with the scenario where each VDEC channel is processed by a separate thread, VDEC is less performant when multiple VDEC channels are processed in serial in a single thread.
ACL_VDEC_CALLBACK_PTR = 3	Decoding callback function. The format is as follows:
ACL_VDEC_CHANNEL_ID_UINT32 = 4	Channel ID. Atlas A2 training product/Atlas A2 inference product
ACL_VDEC_ENCODE_TYPE_UINT32 = 5	Video coding protocol. For details, see acldvppStreamFormat.
ACL_VDEC_OUT_PIC_FORMAT_UINT32 = 6	YUV image storage format. For details, see Table 1.
ACL_VDEC_OUT_PIC_WIDTH_UINT32 = 7	Maximum output width.
ACL_VDEC_OUT_PIC_HEIGHT_UINT32 = 8	Maximum output height.
ACL_VDEC_REF_FRAME_NUM_UINT32 = 9	Number of reference frames. Must be in the range of [0, 16].
ACL_VDEC_BIT_DEPTH_UINT32 = 10	Video bit depth.
