hi35xx 能只编码一路vga分辨率的h264吗？摄像头是720p@30fps的。

小白刚入坑，设置一路vga就报 SAMPLE_PRT("get venc stream time out, exit thread\n");

可以的，如果其他编码正常，说明程序哪里配置有问题导致超时

还是没试出来.看看高人能否看出破绽?

次码流不能独立存在？

一、重要概念

主次码流

主次码流是指硬件逻辑单元启动一次同时产生的 2 路码流，即 1 路主码流和 1 路次码流。主码流和次码流可以为不同的编码协议，但其宽高比例都必须满足 1:1、1:2 或 1:4，次码流不能单独存在（必须和 1 路主码流在同一个通道组中） 。

Re: hi35xx 能只编码一路vga分辨率的h264吗？摄像头是720p@30fps的。

海思的RTSP推流服务器，PC用ffmpeg解码显示no existing PPS 0 reference，no frame，有什么办法？还有PC端的ffmpeg不能解码720p以上分辨率的，invalid UE holomb code！得用海思的PC 解码库？
