您好，根据您的打印信息无法运行的原因可能是CMA内存不足导致编码创建环形缓冲区失败导致，请尝试执行killall rkipc 或 RkLunch-stop.sh 关闭系统默认的rkipc进程，提供更多的内存空间让系统可以正常调度。
由于我们实验的平台为luckfox-pico pro/max 平台，具有充分的内存资源所以在分配CMA时也相比较mini/plus分配了更多，如果您使用的是rv1103(mini/plus)，请尝试降低摄像头捕获分辨率来确保程序的正常运行。

请问如何调整分辨率呢？
调整分辨率有没有特别的注意事项

您好，调整分辨率在main函数中的width和height部分 分辨率的调整目前比较常用的分辨率比如 1920*1080 、1280*720、 720*480都是可以的，您可以根据需求进一步调整。
