rv1126 视频编解码主要与什么相关

见愁

请教一下各位大佬：
1、rv1126 是支持视频编解码：3840*2160 @30fps
这里的编解码这要是与芯片的什么相关：
是与NPU算力有关吗?

2、这里3840*2160 @30fps：3840*2160*60=2488 3200 0
那是否支持720p @100fps？

dmes没什么东西，不知道官方什么时候可以删除这个log的上传，每次发帖都必须上传log，感觉没必要

跟 vpu 有关

大佬，如果我的芯片vpu是支持：3840*2160@30fps，那么是不是只要处理单元不超过：
3840*2160*30=2488 3200 0就可以
这里以：1280*720*120 =1105 9200 0 为例子，
芯片处理1280*720@120fps？可以？

要看硬件最短的解码时间支不支持这么高的 fps。你可以找个 h264/h265 的视频，用 mpi_dec_test 去测试下。最终会有个测试结果的。

大佬，这样，是不是最高支持130fps

大佬，这样，是不是最高支持130fps

先执行这个命令查看硬件解码时间：

1. echo 0x0100 > /sys/module/rk_vcodec/parameters/mpp_dev_debug

复制代码

然后再跑 demo 就能看到每帧硬件解码的时间。

799959745

然后根据 1s/硬件解码时间 = xxx fps 计算即可
