本帖最后由 qn1522720710 于 2019-10-26 09:02 编辑 第一次使用REGSION，希望前辈给我解解疑惑： 上传一个图片，海思的REGSION的模块信息。 REGSION 模块我使用的是 模块号                区域号                支持区域与否                设备号                        通道号 HI_ID_GROUP  OVERLAY_RGN                Y         [0,VENC_MAX_GRP_NUM-1]          0 (我对这里有些疑惑：设置设备号，overlay始终是显示在VENC_chn0上，莫非HI_ID_GROUP只能显示第一路上？) 4路的VENC通道已经有视频，VI VPSS VENC绑定关系如下： for (j=0; j {         ViChn = j * stViParam.s32ViChnInterval;// 0 4 8 12         stSrcChn.enModId = HI_ID_VIU;         stSrcChn.s32DevId = 0;         stSrcChn.s32ChnId = ViChn;                 stDestChn.enModId = HI_ID_VPSS;         stDestChn.s32DevId = VpssGrp;// 0 1 2 3         stDestChn.s32ChnId = 0;         HI_MPI_SYS_Bind(&stSrcChn, &stDestChn);         VpssGrp ++; } for (i=0; i {         VencGrp = i;         VencChn = i;         VpssGrp = i;         SAMPLE_COMM_VENC_Start(VencGrp, VencChn, enPayLoad[0],w,h,enRcMode)         SAMPLE_COMM_VENC_BindVpss(VencGrp, VpssGrp, VPSS_BSTR_CHN); }

本帖最后由 qn1522720710 于 2020-3-3 16:24 编辑 请教下：海思hi35xx芯片，输入一个VI信号，裁剪成4路再推4条流出去，有什么好的实现方法？

你好，请教个问题！ 海思VO直接可以直接输出BMP位图吗？ 还是，只能bmp转成jpg，vdec-》vo才能ok？
