This file describes the interface of ISVCDecoder
Class:ISVCDecoder
Initilaize decoder.
Return:0 - success; otherwise - failed;
| Name | Type | Descritpion |
| pParam | const SDecodingParam * | parameter for decoder |
Uninitialize the decoder.
Decode one frame.
Return:0 - success; otherwise -failed;
| Name | Type | Descritpion |
| pSrc | const unsigned char * | the h264 stream to be decoded |
| iSrcLen | const int | the length of h264 stream |
| ppDst | unsigned char ** | buffer pointer of decoded data (YUV) |
| pStride | int * | output stride |
| iWidth | int & | output width |
| iHeight | int & | output height |
For slice level DecodeFrame2() (4 parameters input), whatever the function return value is, the output data of I420 format will only be available when pDstInfo->iBufferStatus == 1,. (e.g., in multi-slice cases, only when the whole picture is completely reconstructed, this variable would be set equal to 1.)
Return:0 - success; otherwise -failed;
| Name | Type | Descritpion |
| pSrc | const unsigned char * | the h264 stream to be decoded |
| iSrcLen | const int | the length of h264 stream |
| ppDst | unsigned char ** | buffer pointer of decoded data (YUV) |
| pDstInfo | SBufferInfo * | information provided to API(width, height, etc.) |
This function parse input bitstream only, and rewrite possible SVC syntax to AVC syntax.
Return:0 - success; otherwise -failed;
| Name | Type | Descritpion |
| pSrc | const unsigned char * | the h264 stream to be decoded |
| iSrcLen | const int | the length of h264 stream |
| pDstInfo | SParserBsInfo * | bit stream info |
This API does not work for now!! This is for future use to support non-I420 color format output.
Return:to do ...
