Research direction

Reproduce streaming on the Mi Box S 3rd gen with automatic codec and HEVC, then compare it with AV1 and H264 under the listed Android 14 and Windows 11 24h2 setup. Investigate the client behavior for this device and codec combination; done means HEVC no longer produces a black screen and AV1 no longer lags, or the issue is identified as a device limitation.
