这是局域网设备

我把帧率改成25fps也是一样的信息欸

[fallen-queen]

麻烦提供一下工具链信息，我更新一下SDK，加点打印排查一下，谢谢。

[Martin]

aarch64-linux-gnu-gcc编译的

这是SDK打印信息

[fallen-queen]

视频帧的pts有问题，看着是一直不变的，pts要求是微秒量级的时间戳。

[Martin]

我是根据帧率设置的，帧率从30帧改到25、20，我都会改。

[fallen-queen]

pts是需要累加的，少了+号。

[fallen-queen]

我是根据帧率设置的，帧率从30帧改到25、20，我都会改。

建议参考demo的做法，设置一个pts变量，进行累加

[Martin]

好的，我改成图片显示这样还是有这个信息：
[03-08 11:20:58 TUYA D][tuya_ring_buffer.c:343] ch0st0tr0 delay too much(seqNo:566->758)

[03-08 11:20:58 TUYA D][tuya_ring_buffer.c:1076] skip to next frame, type(1) node 181 seqNo 581 ch0st0tr0
而且我看demo里面每次循环都先赋值0
log如文件
