android - Higher decoding latency on Snapdragon devices compared to Exynos devices with h264

Question

I made the observation that for devices in the same price range, Snapdragon-based decoders can have a much higher decoding latency than Exynos-based decoders. This is most noticable when decoding h264 streams with the value "pic_order_cnt_type" inside the SPS set to 0 instead of 2. I am wondering if you have also observed this behaviour and if there is any fix for that ( I have already opened an issue here but no response so far)

Some technical details:

I have built a simple example app that uses AMediaCodec to decode h264 streams. It uploads the "decoding latency", as a test result into a Firestore database. code

Here is a comparison of the decoding latency for different h264 streams on a Pixel 4 (using snapdragon decoder) and a Samsung Galaxy Note 9 (using exynos decoder):
