Rust SDKs

Fixes

• Reject oversized data messages before they break the data channel.
• Upgrade dashmap to v6
• Add per-publication video encoder backend selection. Add a video encoder backend availability query. Remove LIVEKIT_PREFERRED_HW_ENCODER in favor of per-publication backend selection.

Fixes

• Fix NVIDIA encoder I420 uploads to copy each plane using its actual source stride, avoiding chroma corruption when source frames use padded YUV planes. Also fix the local_video publisher reusing mutable I420 frame storage after handing frames to WebRTC.

• Keep one-frame native video streams as latest-frame queues. Move local video subscriber timing metrics into the example and use the WGPU paint callback as the render boundary.

Fixes

• Add rpc max_round_trip_latency and move to builder pattern - #1127 (@1egoman)
• [allow(dead_code)] for dead function in room module - #1128 (@stephen-derosa)
• Send publisher offer with join request to accelerate connection - #996 (@cnderrauber)

Fixes

• bump protocol to v1.46.4 - #1121 (@lukasIO)

Fixes

• Add native video pipeline timing instrumentation for local video measurements, exposing local publish and subscribe timing through async streams and subscriber overlay GPU upload and receive-to-GPU latency metrics through explicit timing observers.

feat: add Android application context initialization for PlatformAudio support.

Android requires ContextUtils.initialize(applicationContext) before WebRTC audio components can be created. This change:

• Adds livekit_ffi_initialize_android_context() C FFI function for Unity and other FFI consumers
• Uses CreateAndroidAudioDeviceModule() instead of generic CreateAudioDeviceModule() on Android
• Handles empty device GUIDs on Android (falls back to index 0)
• Documents Android-specific limitations: single default device, no app-level device selection

Platform notes:

• Android device enumeration returns only one "default" device with empty name/GUID
• Audio routing (speaker/earpiece/Bluetooth) is controlled by Android's AudioManager, not WebRTC

Fixes

• Filter internal data streams out of livekit-ffi interface - #1112 (@1egoman)
