Encoder Parameters ENCODER PARAMETER DEPENDENCY NVVE_RC_TYPE: For RC_VBR, the parameters NVVE_AVG_BITRATE and NVVE_PEAK_BITRATE take effect. For RC_CQP, the parameters NVVE_QP_LEVEL_INTER_P, NVVE_QP_LEVEL_INTER_B and NVVE_QP_LEVEL_INTRA take effect. For RC_CBR, the parameter NVVE_AVG_BITRATE takes effect. For RC_VBR_MINQP, the parameters NVVE_AVG_BITRATE, NVVE_PEAK_BITRATE, NVVE_QP_LEVEL_INTER_P, NVVE_QP_LEVEL_INTER_B and NVVE_QP_LEVEL_INTRA take effect. In this mode, since the encoder is limiting the min value of QP, the resulting bitrate can be lower – and potentially significantly lower – than the average bitrate. NVVE_CLEAR_STAT: Resets the statistic values for following parameters (mentioned in Encoder Query Parameters on page 29: NVVE_STAT_NUM_CODED_FRAMES, NVVE_STAT_NUM_RECEIVED_FRAMES, NVVE_STAT_BITRATE, NVVE_STAT_NUM_BITS_GENERATED, NVVE_GET_PTS_DIFF_TIME, NVVE_GET_PTS_CODED_TIME, NVVE_GET_PTS_RECEIVED_TIME, NVVE_STAT_ELAPSED_TIME, NVVE_STAT_QBUF_FULLNESS, NVVE_STAT_PERF_FPS, NVVE_STAT_PERF_AVG_TIME. NVVE_OUT_SIZE/NVVE_IN_SIZE: For DirectShow Filter, NVVE_IN_SIZE will return the dimensions based on the pin connection at the input pin. For C-lib API, NVVE_IN_SIZE will set the input dimensions for the encoder. NVVE_OUT_SIZE is used to specify the targeted encoded output dimensions. NVVE_DEVICE_MEMORY_INPUT / NVVE_DEVICE_CTX_LOCK: Device Context Lock parameter must also be set if device memory input is enabled. Context lock should be created from cuvidCtxLockCreate API available in NVCUVID. NVIDIA CUDA VIDEO ENCODER SP04456-001_v03 | 30
