• Unsigned tester build, so Windows may show a publisher warning.

The reported version is 0.0.0. Branch builds do not derive a version from a tag, and the fix for that is a separate pull request (Nonary#352) rather than part of this AMD-only change. Identify this build by the commit hash embedded in the binary or by the SHA-256 above.

What it contains

• Native AMD AMF encoder for H.264, HEVC and AV1 with D3D11 zero-copy input, replacing the FFmpeg path for amdvce. amdvce_legacy remains as an explicit rollback and is never selected automatically.
• Every AMF property is set and read back, so a rejected or altered value fails encoder creation instead of streaming a different configuration.
• Bounded submit retries, input ring, surface pool, and teardown watchdogs. Driver resets and output stalls rebuild the same native session rather than ending the stream.
• Xbox intra-refresh for all three codecs on a 300-frame cycle.
• Split-frame encoding on HEVC and AV1 where the GPU reports more than one VCN instance.

Measured on an RX 7900 XT at 1080p120, 50 Mbps AV1: encode median 2.28 to 2.47 ms depending on profile, with no AMF warnings or fatal errors.

Most useful things to test: AMD hardware other than RDNA3, a real Xbox client for the intra-refresh path, HDR sessions, and two clients streaming at once. Please include GPU, driver version, codec, HDR state, and reconnect behavior.
