IMX8MP录制报错

[FanS2023]

Hi NXP

我们使用的是IMX8MP平台，实现DP视频录制功能

在测试中发现warning，log如下：

请教下，这种问题发生的原因及会造成的影响？

十分感谢！

Hello,

Are you tring to run video that is not supported by NXP? this is common warning that appear.

这个warning发生的原因是因为SOC检测到了不支持的视频么？

视频源是PC，输出DP 1080P，录制开始无此警告，长时间录制会出现，想确认下影响，会不会对dv-timing等造成影响
