哪个用过硬解，我想问一下，upv_api.h这个里面的函数在哪个地方实现的，我找了好久没有找到。
就是下面以的
typedef struct VpuCodecContext {
void* vpuApiObj;
CODEC_TYPE codecType;
OMX_RK_VIDEO_CODINGTYPE videoCoding;
RK_U32 width;
RK_U32 height;
RK_U8 *extradata;
RK_S32 extradata_size;
RK_U8 enableparsing;
RK_S32 no_thread;
EXtraCfg_t extra_cfg;
void* private_data;
/*
** 1: error state(not working) 0: working
*/
RK_S32 decoder_err;
/**
* Allocate and initialize an VpuCodecContext.
*
* @param ctx The context of vpu api, allocated in this function.
* @param extraData The extra data of codec, some codecs need / can
* use extradata like Huffman tables, also live VC1 codec can
* use extradata to initialize itself.
* @param extra_size The size of extra data.
*
* @return 0 for init success, others for failure.
* note: check whether ctx has been allocated success after you do init.
*/
RK_S32 (*init)(struct VpuCodecContext *ctx, RK_U8 *extraData, RK_U32 extra_size);
/**
* @return 0 for decode success, others for failure.
*/
RK_S32 (*decode)(struct VpuCodecContext *ctx, VideoPacket_t *pkt, DecoderOut_t *aDecOut);
/**
* @return 0 for encode success, others for failure.
*/
RK_S32 (*encode)(struct VpuCodecContext *ctx, EncInputStream_t *aEncInStrm, EncoderOut_t *aEncOut);
/**
* flush codec while do fast forward playing.
*
* @return 0 for flush success, others for failure.
*/
RK_S32 (*flush)(struct VpuCodecContext *ctx);
RK_S32 (*control)(struct VpuCodecContext *ctx, VPU_API_CMD cmdType, void* param);
/**
*seperate the decode function to two function
*
*/
RK_S32 (*decode_sendstream)(struct VpuCodecContext *ctx, VideoPacket_t *pkt);
RK_S32 (*decode_getframe)(struct VpuCodecContext *ctx, DecoderOut_t *aDecOut);
RK_S32 (*encoder_sendframe)(struct VpuCodecContext *ctx, EncInputStream_t *aEncInStrm);
RK_S32 (*encoder_getstream)(struct VpuCodecContext *ctx, EncoderOut_t *aEncOut);
}VpuCodecContext_t;
