RV1126通过创建多线程获取高低编码器的分辨率视频

效果高VENC低VENC占用空间高分辨率的是20几MB低分辨率是几MB编码流程一、VIVideo Input 视频输入模块初始化使能通道int ret; RK_MPI_SYS_Init(); // VI Init...... VI_CHN_ATTR_S vi_chn_attr; vi_chn_attr.pcVideoNode rkispp_scale0;//设置视频设备节点路径 vi_chn_attr.u32Width 1920;//设置分辨率的宽度 vi_chn_attr.u32Height 1080;//设置分辨率的高度 vi_chn_attr.enPixFmt IMAGE_TYPE_NV12;//设置图像类型 vi_chn_attr.enBufType VI_CHN_BUF_TYPE_MMAP;//设置VI获取类型 vi_chn_attr.u32BufCnt 3;//设置缓冲数量 vi_chn_attr.enWorkMode VI_WORK_MODE_NORMAL;//设置VI工作类型 ret RK_MPI_VI_SetChnAttr(PIPE_ID,VI_CHN_ID,vi_chn_attr); if(ret) { printf(Video Input channel deploy failed ....\n); return -1; } else { printf(Video Input channel deploy success! ----------\n); } //Enable Channel ret RK_MPI_VI_EnableChn(PIPE_ID,VI_CHN_ID); if(ret) { printf(Enable Channel failed!....\n); return -2; } else { printf(Enable Channel success!--------\n); }二、RGA图像模块初始化//set RGA RGA_ATTR_S My_RGA_Init; //Input My_RGA_Init.stImgIn.u32Width 1920; My_RGA_Init.stImgIn.u32Height 1080; My_RGA_Init.stImgIn.u32HorStride 1920; My_RGA_Init.stImgIn.u32VirStride 1080; My_RGA_Init.stImgIn.imgType IMAGE_TYPE_NV12; My_RGA_Init.stImgIn.u32X 0; My_RGA_Init.stImgIn.u32Y 0; //Output My_RGA_Init.stImgOut.u32Width 1280; My_RGA_Init.stImgOut.u32Height 720; My_RGA_Init.stImgOut.u32HorStride 1280; My_RGA_Init.stImgOut.u32VirStride 720; My_RGA_Init.stImgOut.imgType IMAGE_TYPE_NV12; My_RGA_Init.stImgOut.u32X 0; My_RGA_Init.stImgOut.u32Y 0; My_RGA_Init.u16Rotaion 0; My_RGA_Init.bEnBufPool RK_TRUE; My_RGA_Init.u16BufPoolCnt 3; My_RGA_Init.enFlip RGA_FLIP_H; ret RK_MPI_RGA_CreateChn(RGA_CHN_ID,My_RGA_Init); if(ret) { printf(RGA_Channel create failed!....\n); return -3; } else { printf(RGA_Channel create success!--------\n); }三、配置高分辨率编码器//set high_venc VENC_CHN_ATTR_S My_High_venc; //set stVencAttr My_High_venc.stVencAttr.enType RK_CODEC_TYPE_H264; My_High_venc.stVencAttr.imageType IMAGE_TYPE_NV12; My_High_venc.stVencAttr.u32VirWidth 1920; My_High_venc.stVencAttr.u32VirHeight 1080; My_High_venc.stVencAttr.u32Profile 66; My_High_venc.stVencAttr.u32PicWidth 1920; My_High_venc.stVencAttr.u32PicHeight 1080; My_High_venc.stVencAttr.enRotation VENC_ROTATION_0; //SET stRcAttr My_High_venc.stRcAttr.enRcMode VENC_RC_MODE_H264CBR; My_High_venc.stRcAttr.stH264Cbr.u32Gop 25; My_High_venc.stRcAttr.stH264Cbr.u32SrcFrameRateDen 1; My_High_venc.stRcAttr.stH264Cbr.u32SrcFrameRateNum 25; My_High_venc.stRcAttr.stH264Cbr.fr32DstFrameRateDen 1; My_High_venc.stRcAttr.stH264Cbr.fr32DstFrameRateNum 25; My_High_venc.stRcAttr.stH264Cbr.u32BitRate 8388608; ret RK_MPI_VENC_CreateChn(HIGH_VENC_CHN,My_High_venc); if(ret) { printf(HIGH_VENC Create failed!....\n); return -4; } else { printf(HIGH_VENC Create success!--------\n); }四、设置低分辨率编码器//set low_venc VENC_CHN_ATTR_S My_Low_venc; //set stVencAttr My_Low_venc.stVencAttr.enType RK_CODEC_TYPE_H264; My_Low_venc.stVencAttr.imageType IMAGE_TYPE_NV12; My_Low_venc.stVencAttr.u32VirWidth 1280; My_Low_venc.stVencAttr.u32VirHeight 720; My_Low_venc.stVencAttr.u32Profile 66; My_Low_venc.stVencAttr.u32PicWidth 1280; My_Low_venc.stVencAttr.u32PicHeight 720; My_Low_venc.stVencAttr.enRotation VENC_ROTATION_0; //SET stRcAttr My_Low_venc.stRcAttr.enRcMode VENC_RC_MODE_H264CBR; My_Low_venc.stRcAttr.stH264Cbr.u32Gop 25; My_Low_venc.stRcAttr.stH264Cbr.u32SrcFrameRateDen 1; My_Low_venc.stRcAttr.stH264Cbr.u32SrcFrameRateNum 25; My_Low_venc.stRcAttr.stH264Cbr.fr32DstFrameRateDen 1; My_Low_venc.stRcAttr.stH264Cbr.fr32DstFrameRateNum 25; My_Low_venc.stRcAttr.stH264Cbr.u32BitRate 2097152; ret RK_MPI_VENC_CreateChn(LOW_VENC_CHN,My_Low_venc); if(ret) { printf(LOW_VENC_CHN Create failed!....\n); return -5; } else { printf(LOW_VENC_CHN Create success!--------\n); }五、绑定然后创建线程六、全部代码是这样的#include assert.h #include fcntl.h #include getopt.h #include pthread.h #include signal.h #include stdbool.h #include stdio.h #include stdlib.h #include time.h #include unistd.h // #include common/sample_common.h #include rkmedia_api.h #define PIPE_ID 0 #define VI_CHN_ID 0 #define RGA_CHN_ID 0 #define HIGH_VENC_CHN 0 #define LOW_VENC_CHN 1 void *get_high_venc_thread(void *rags); void *rga_handle_thread(void *args); void *get_low_venc_thread(void *rags); int main(int argc, char *argv[]) { int ret; RK_MPI_SYS_Init(); // VI Init......
