RT1176 .264 video playback

We use RT1176 to play video in .264 format, and the maximum frame rate for 720p playback is 4Hz. I learned that RT1060 plays 720p with a maximum frame rate of 4Hz, but RT1060 only has 600M main frequency, while RT1176 has 1G main frequency, so I think RT1176 The frame rate of 720p video in .264 format should be greater than 4Hz.

1. Is my conclusion that the 4Hz frame rate is correct, or is my operation wrong?
2. Is it possible that I want to play 720p video at 15Hz frame rate?

HI @liangtaotongxue ,

You can refer to this demo https://github.com/JayHeng/RT-Mp4Player

So, maybe you can lift the framerate by more optimization. But it seems it's really hard to get 15pfs at 1GHz.
