Description

Describe the bug

On my OnePlus Nord 3 5G (Mediatek Dimensity 9000 high-end SoC) I get around 30 ms of decoding latency with both H.264 and H.265. It's a lot, considering that on my Sony Android TV (also with a Mediatek SoC) I get around 3 ms. I already tried changing resolution, FPS and bitrate but it won't get better latencies.

Research direction

Start by reproducing the reported latency on the OnePlus Nord 3 5G with Android 13 using H.264 and H.265, then compare it with the reported Sony Android TV result. The issue names no source files or tests and does not define a code change; done would require identifying the cause and documenting a verified improvement or resolution.
