Function Documentation

◆ rocDecCreateDecoder()

rocDecStatus ROCDECAPI rocDecCreateDecoder ( rocDecDecoderHandle *  decoder_handle,
RocDecoderCreateInfo *  decoder_create_info 
)

Create the decoder object based on decoder_create_info. A handle to the created decoder is returned

◆ rocDecDecodeFrame()

rocDecStatus ROCDECAPI rocDecDecodeFrame ( rocDecDecoderHandle  decoder_handle,
RocdecPicParams *  pic_params 
)

Decodes a single picture Submits the frame for HW decoding

◆ rocDecDestroyDecoder()

rocDecStatus ROCDECAPI rocDecDestroyDecoder ( rocDecDecoderHandle  decoder_handle)

Destroy the decoder object

◆ rocDecGetDecodeStatus()

rocDecStatus ROCDECAPI rocDecGetDecodeStatus ( rocDecDecoderHandle  decoder_handle,
int  pic_idx,
RocdecDecodeStatus *  decode_status 
)

Get the decode status for frame corresponding to nPicIdx API is currently supported for HEVC, AVC/H264 and JPEG codecs. API returns ROCDEC_NOT_SUPPORTED error code for unsupported GPU or codec.

◆ rocDecGetErrorName()

const char *ROCDECAPI rocDecGetErrorName ( rocDecStatus  rocdec_status)

Return name of the specified error code in text form.

◆ rocDecReconfigureDecoder()

rocDecStatus ROCDECAPI rocDecReconfigureDecoder ( rocDecDecoderHandle  decoder_handle,
RocdecReconfigureDecoderInfo *  reconfig_params 
)

Used to reuse single decoder for multiple clips. Currently supports resolution change, resize params params, target area params change for same codec. Must be called during RocdecParserParams::pfn_sequence_callback
