…ests Point moonlight-common-c at the AsafMah fork's integration/client-resolution branch (mic b91c7cd + qiin2333/moonlight-common-c#10 + qiin2333#13). It adds LiSendResolutionChangeRequest() and LI_FF_CLIENT_RESOLUTION_CHANGE, and hardens control-stream sends against concurrent teardown. Temporary: switch the URL back to qiin2333/moonlight-common-c once those changes land on mic.

Add an opt-in "Match stream resolution to window size" display setting. When the host sets LI_FF_CLIENT_RESOLUTION_CHANGE for the session, a settled window resize (400 ms debounce) asks the host for the window's pixel size via LiSendResolutionChangeRequest(). Fullscreen asks for the configured resolution again. Sizes outside the host's 256-16384 range, the current stream size, and repeats of an unanswered request are not sent, and LI_RESOLUTION_CHANGE_ERR_UNSUPPORTED turns the feature off for the connection. The host reports its display size (0x5507) at stream start and on every display change, and only applies requests or follows its display while it streams that display 1:1. The first report of a connection is therefore only recorded, later reports change the stream size only if the host was 1:1, and requests are held back (and retried on the next report) while it isn't. On a stream size change, the old decoder is destroyed under m_DecoderLock and the existing SDL_RENDER_DEVICE_RESET path rebuilds it, so the old decoder never sees frames of the new size. The reset path also syncs the input handler's stream dimensions, which keeps absolute mouse/touch/pen mapping correct after a resolution change or a reconnect. One request is outstanding at a time (answered or 5 s timeout, since the host ignores requests silently). Host-initiated changes are not fought: only an actual resize, or a retry of a skipped match, sends a request. Resolution reports from a previous connection are dropped at connection boundaries, and one received while a reconnect is starting is handled once the new connection is up. Closes qiin2333#103.

Explanation
Issue [
#103] requires requests only for enabled, supported, windowed sessions. The implementation satisfies the opt-in setting, capability gate, debounce, physical-pixel sizing, even dimensions, limits, request tracking, host reports, decoder reset, and input-dimension update. However,processWindowResolutionMatch()selectsm_StreamConfigwhenisStreamingWindowFullscreen()is true and can then callLiSendResolutionChangeRequest(). This permits a resolution request in fullscreen mode.Resolution

Update the stale moonlight-common-c documentation.
The pinned commit and LiSendResolutionChangeRequest API are available from AsafMah/moonlight-common-c. However, docs/architecture.md still identifies qiin2333/moonlight-common-c and its mic branch. Update the entry to document the configured remote and the integration/client-resolution branch containing the pinned commit.

Summary
Adds an opt-in Match stream resolution to window size setting (Settings → Display). When the stream window is resized, Moonlight asks a compatible host to switch to the window's pixel size, and it rebuilds the decoder whenever the host's stream resolution changes. Closes #103 and follows up on #84.
How it works
LI_FF_CLIENT_RESOLUTION_CHANGE(0x400) in the session's feature flags. The host computes this per session and folds in all of its preconditions. Moonlight reads it once each connection is up, including after a reconnect.LI_RESOLUTION_CHANGE_ERR_UNSUPPORTEDturns the feature off for that connection.SDL_WINDOWEVENT_SIZE_CHANGEDrestarts a 400 ms debounce. Once the size settles, Moonlight computes a target:SDL_GetWindowSizeInPixels). In fullscreen, the configured stream resolution.SDL_WINDOWEVENT_RESTORED. A plain minimize/restore with no pending match sends nothing, so host-initiated changes are never reverted.resolutionChangedcallback is posted to the main thread. On a stream size change, Moonlight queuesSDL_RENDER_DEVICE_RESET, then destroys the old decoder underm_DecoderLock, so the old decoder never decodes a frame at the new size.drSubmitDecodeUnit()drops frames until the existing reset path builds the new decoder and requests an IDR frame. No reset logic is duplicated.SdlInputHandler's stream dimensions from the active video size, so absolute mouse, touch, and pen mapping stays correct after a resolution change and after a reconnect.Commits
