@jokiin Yeah that's not very helpful at all, unless there's more to see after that. HiSilicon's Hi3559 V200 found in the DDPai Mini 5 for example mentions the below:
Video Encoding and Decoding Performance
- Maximum resolution for H.265/H.264 encoding and decoding: 3840 x 2160
- H.265/H.264 encoding and decoding performance:
- Maximum resolution for JPEG encoding and decoding: 8192 x 8192
- Maximum JPEG encoding and decoding performance: 16 MP (4608 x 3456)@10 fps
- Multiple bit rate control modes such as CBR, VBR, and FIXQP
- Maximum bit rate for H.265/H.264 encoding output: 100 Mbit/s
- Encoding of eight ROIs
From here we know if the files produced are much larger than 12.5 MB/sec, it likely has been padded by the CPU and will not contain very much more visual information than if there was another setting that produced a file which is around 12.5 MB/sec. Since the CPU is 2x Cortex A7 @ 900 MHz, the CPU itself is unlikely able to assist very much in this task. The datasheet also mentions a couple of hardware processing capabilities under the ISP section with stuff like shake compensation, noise reduction, methods of WDR supported, etc.
But perhaps the most interesting is this. Opens up a large field of possibilities for the dashcam developer depending on how hard they want to work their software development team. Maybe a future 70Mai model might be able to highlight some of these capabilities.
