问题描述
我明显的看到我的日志里面有一个：kd_mpi_venc_get_stream[0] error ret:0
但是我不知道含义，我的代码是抄mp4_muxer的，get_stream是一样的，但我把aenc去掉了，绑定方式我先后尝试了注释掉的和现在的，但都没有区别，vb块也是4k对齐，没找到问题在哪
static k_s32 start_run(SampleCtx *psample_ctx) {
k_s32 ret = kd_mapi_venc_start(0, -1);
if (ret != K_SUCCESS) {
printf("venc chn start failed, %x.\n", ret);
return -1;
}
/*ret = kd_mapi_venc_bind_vi(vicap_dev, VICAP_CHN_ID_2, 0);
if (ret != K_SUCCESS) {
printf("venc chn bind vi failed, %x.\n", ret);
goto venc_stop;
}*/

vi_chn.mod_id = K_ID_VI;
vi_chn.dev_id = VICAP_DEV_ID_0;
vi_chn.chn_id = VICAP_CHN_ID_2; // 你的图像通道

venc_chn.chn_id = 0;
ret = kd_mpi_sys_bind(&vi_chn, &venc_chn);
if (ret != 0) {
printf("sys bind vi -> venc failed!!!\n");
return -1;
}
ret = kd_mapi_vicap_start(VICAP_DEV_ID_0);
if (ret != K_SUCCESS) {
printf("kd_mapi_vicap_start failed, %x.\n", ret);
}
return 0;

复现步骤
这是vb块的：
int sample_vb_init(void)
{
k_u32 pic_width = sample_context.video_pic_width;
k_u32 pic_height = sample_context.video_pic_height;
k_s32 ret;
k_vb_config config;
memset(&config, 0, sizeof(config));
config.max_pool_cnt = 5;
//VB for YUV420SP output
config.comm_pool[0].blk_cnt = 5;
config.comm_pool[0].mode = VB_REMAP_MODE_NOCACHE;
config.comm_pool[0].blk_size = VICAP_ALIGN_UP((ISP_CHN0_WIDTH * ISP_CHN0_HEIGHT * 3 / 2), VICAP_ALIGN_1K);
//VB for RGB888 output
config.comm_pool[1].blk_cnt = 5;
config.comm_pool[1].mode = VB_REMAP_MODE_NOCACHE;
config.comm_pool[1].blk_size = VICAP_ALIGN_UP((ISP_CHN1_HEIGHT * ISP_CHN1_WIDTH * 3 ), VICAP_ALIGN_1K);
//VB for YUV420SP venc in
config.comm_pool[2].blk_cnt = 5;
config.comm_pool[2].mode = VB_REMAP_MODE_NOCACHE;
config.comm_pool[2].blk_size = VICAP_ALIGN_UP((ISP_CHN0_WIDTH * ISP_CHN0_HEIGHT * 3 / 2), 0x1000);//4k对齐
// video pool parameter
k_u32 pic_size = pic_width * pic_height * 3 / 2;//yuv格式
k_u32 stream_size = pic_width * pic_height * 3 / 4;//pic_szie的一半大小，因为视频会压缩，体积原小于默认的raw图片
config.comm_pool[3].blk_cnt = 6;//缓存vi的4张，编码器自己占2张
config.comm_pool[3].blk_size = ((pic_size + 0xfff) & ~0xfff);//& ~0xfff = 把低 12 位全部清 0 → 变成 4096 整数倍，进行4k对齐（内存硬性要求）
config.comm_pool[3].mode = VB_REMAP_MODE_NOCACHE;
config.comm_pool[4].blk_cnt = 30;//1s30帧
config.comm_pool[4].blk_size = ((stream_size + 0xfff) & ~0xfff);
config.comm_pool[4].mode = VB_REMAP_MODE_NOCACHE;
ret = kd_mpi_vb_set_config(&config);
if (ret) {
printf("vb_set_config failed ret:%d\n", ret);
return ret;
}
k_vb_supplement_config supplement_config;
memset(&supplement_config, 0, sizeof(supplement_config));
supplement_config.supplement_config |= VB_SUPPLEMENT_JPEG_MASK;
ret = kd_mpi_vb_set_supplement_config(&supplement_config);
if (ret) {
printf("vb_set_supplement_config failed ret:%d\n", ret);
return ret;
}
ret = kd_mpi_vb_init();
if (ret) {
printf("vb_init failed ret:%d\n", ret);
}
return ret;
}
这是vicap通道2的：
