Luckfox Pico RV1103 RV1106 6音频输入时提示音频输入缓存不足是什么情况

2024-05-23 8:06

代码如下，在RK_MPI_AI_GetFrame中返回值为0xA00A800D，查阅手册发现是RK_ERR_AI_NOBUF，这是什么情况

void*sendDataThread(void*ptr) {
   TEST_AI_CTX_S*params= reinterpret_cast<TEST_AI_CTX_S*>(ptr);
   RK_S32result=0;
   RK_S32s32MilliSec=10;
   AUDIO_FRAME_Sframe;
   if (params->dstFilePath) {
       AUDIO_SAVE_FILE_INFO_Ssave;
       save.bCfg=RK_TRUE;
       save.u32FileSize=1024;
       snprintf(save.aFilePath, sizeof(save.aFilePath), "%s", params->dstFilePath);
       snprintf(save.aFileName, sizeof(save.aFileName), "%s", "cap_out.pcm");
       RK_MPI_AI_SaveFile(params->s32DevId, params->s32ChnIndex, &save);
       //printf("save_file\r\n");
   }
   while (!gAiExit) {
       result=RK_MPI_AI_GetFrame(params->s32DevId, params->s32ChnIndex, &frame, RK_NULL, s32MilliSec);
       printf("result=%x\r\n",result);
       if (result==0) {
           void*data=RK_MPI_MB_Handle2VirAddr(frame.pMbBlk);
           RK_U32len=RK_MPI_MB_GetSize(frame.pMbBlk);
           RK_LOGV("data = %p, len = %d", data, len);
           RK_MPI_AI_ReleaseFrame(params->s32DevId, params->s32ChnIndex, &frame, RK_NULL);
       }
   }
   returnRK_NULL;
}

你好，是否修改过 RK_BOOTARGS_CMA_SIZE 的大小，请尝试增大后再进行测试：

这个文件的路径是在哪里呢

2024-05-24 1:13

SDK/project/cfg/BoardConfig_IPC目录下，根据版型修改对应的配置文件，重新选择版型进行编译

Code: Select all

./build.sh lunch
./build.sh

您好，按您说的改了空间大小，现在不会报之前那个错误了，十分感谢。但是会segment fault，看了一下可能的原因：
这是使用pdf里提供的采集指令：

里面有一句open 1monitor_log_leve3
以下是我用的C语言来做的音频输入：

Segmentation fault (core dumped)
里面有一句vsys dev opeln ，想问一下这两种有什么区别，可能导致下面segment fault的问题吗

您好，{monitor_log_level :144} 后的提示不同，可能是输出先后顺序不同导致，录制的音频正常即可。导致段错误的原因可能有多种，建议在代码中增加一些调试信息或使用gdb调试工具，帮助确认每一步操作是否成功。

今天晚上又试了一下又开始报RK_ERR_AI_NOBUF了，重新装系统也无法解决，请问一下这个问题还可能由其他原因造成吗

根据手册，RK_ERR_AI_NOBUF 是由于音频输入缓存不足导致，请继续增大 RK_BOOTARGS_CMA_SIZE，注意确保正确烧录镜像，或先烧录网盘提供的镜像进行测试。
