| #define NVMEDIA_ENCODE_MAX_RPS_SIZE 17U |
Maximum number of reference pictures including current frame.
Definition at line 27 of file nvmedia_iep_input_extradata.h.
| #define NVMEDIA_MAX_ROI_REGIONS 8U |
Maximum number of region of interests.
Definition at line 30 of file nvmedia_iep_input_extradata.h.
Specifies the Video encoder set attribute type.
This can be extended to set other encoding parameter information.
| Enumerator | |
|---|---|
| NvMediaEncSetAttr_DRCParams | This is used to pass dynamic resolution change specific information NvMediaEncodeDRCConfig. Driver will update encode resolution specific parameters for encoding with new specified resolution. Supported for H264 and H265 Encoding. |
| NvMediaEncSetAttr_HWConfigFiles | This attribute is used to pass HW config files as specified in NvVideoEncodeCfgFiles for current encoding session. This is only required for HW validation. This attribute must be set before first frame of encoding. |
Definition at line 92 of file nvmedia_iep_input_extradata.h.
Defines video frame flags.
Each bit of bEncodeParamsFlag indicate parameter for specific featue.

| NvMediaStatus NvMediaIEPSetAttribute | ( | const NvMediaIEP * | encoder, |
| NvMediaEncSetAttrType | attrType, | ||
| uint32_t | attrSize, | ||
| const void * | AttributeData | ||
| ) |
Set the encoder attribute for current encoding session.
This can be called before passing the first frame for encoding.
| [in] | encoder | The encoder to use. |
| [in] | attrType | attribute type as defined in NvMediaEncSetAttrType |
| [in] | attrSize | size of the data structure associated with attribute Possible values are: NvMediaEncSetAttr_DRCParams if resolution of encoding changes. |
| [in] | pointer | to data structure associated with attribute |
| NvMediaStatus NvMediaIEPSetInputExtraData | ( | const NvMediaIEP * | encoder, |
| const void * | extradata | ||
| ) |
Set the encoder extra data for current frame for encoding.
This should be called before before every NvMediaIEPFeedFrame so that parameters can be applied for current frame. This should be called from same thread from where NvMediaIEPFeedFrame is called.
| [in] | encoder | The encoder to use. |
| [in] | extradata | encode input extra data for current frame. Input extradata ia defined as NvMediaEncodeInputExtradata |
