One more thing: the README should be updated to check the "Dynacast" box. |

> [!IMPORTANT] > Merging this pull request will create these releases # livekit 0.7.46 (2026-06-17) ## Features ### Make GLib an opt-in dependency `webrtc-sys` no longer links against `glib-2.0`/`gobject-2.0`/`gio-2.0` by default. Breaking: Wayland screen sharing now requires the `glib-main-loop` feature on `livekit` (or `libwebrtc`). ## Fixes - Add track publishing doc example - Fix silent subscription failures in single-pc mode when the SFU reuses an existing empty transceiver for a new remote track. Also make `RtpTransceiver::mid()` safe to call on transceivers that haven't been negotiated yet — libwebrtc is built with `-fno-exceptions`, so `std::optional::value()` aborted the process instead of throwing. - Add `LK_DISABLE_NVDEC` to bypass NVIDIA NVDEC decoder registration when the environment variable is set. - return DeviceNotFound when device is not there for set_recording_devi… - #1155 (@xianshijing-lk) ### Add dynacast support - #1003 (@chenosaurus, @stephen-derosa) This includes a minor breaking change for `libwebrtc`: `RtpParameters` now contains additional RTP sender state that must be preserved when round-tripping through `set_parameters()`. # livekit-ffi 0.12.64 (2026-06-17) ## Fixes - Add `LK_DISABLE_NVDEC` to bypass NVIDIA NVDEC decoder registration when the environment variable is set. - return DeviceNotFound when device is not there for set_recording_devi… - #1155 (@xianshijing-lk) ### Add dynacast support - #1003 (@chenosaurus, @stephen-derosa) This includes a minor breaking change for `libwebrtc`: `RtpParameters` now contains additional RTP sender state that must be preserved when round-tripping through `set_parameters()`. # livekit-api 0.5.2 (2026-06-17) ## Fixes ### Shrink binaries with an HMAC-only JWT crypto provider `livekit-api` now installs a minimal in-crate HMAC `CryptoProvider` (HS256/384/512) instead of jsonwebtoken's `rust_crypto` backend, dropping the unused RSA/EC/EdDSA algorithms. LiveKit access tokens are HS256, so there is no public API or behavior change. This trims ~200 KiB of unreachable crypto code, shrinking the shipped binaries ~25–29% — the `RustLiveKitUniFFI` iOS framework drops from ~900 KiB to ~672 KiB (arm64) and the Android arm64-v8a `.so` from ~1.13 MiB to ~816 KiB. `livekit-ffi` and `livekit` benefit too. ### fix: surface full error chain in region fetch failures for better TLS error diagnosis. When connecting to LiveKit Cloud from containers without CA certificates installed, the error message now includes the full error chain (e.g., "invalid peer certificate: UnknownIssuer") instead of just "error sending request for url (...)". This makes TLS certificate issues self-diagnosing. Also added documentation for TLS features in Cargo.toml, highlighting `rustls-tls-webpki-roots` as the recommended option for container deployments. # webrtc-sys 0.3.35 (2026-06-17) ## Fixes - Fix silent subscription failures in single-pc mode when the SFU reuses an existing empty transceiver for a new remote track. Also make `RtpTransceiver::mid()` safe to call on transceivers that haven't been negotiated yet — libwebrtc is built with `-fno-exceptions`, so `std::optional::value()` aborted the process instead of throwing. - Add `LK_DISABLE_NVDEC` to bypass NVIDIA NVDEC decoder registration when the environment variable is set. - Add Jetson DMA-buffer video publishing support for libargus MIPI capture and the Jetson hardware encoder, including AV1 hardware encoding on supported Jetson Orin devices. ### Make GLib an opt-in dependency `webrtc-sys` no longer links against `glib-2.0`/`gobject-2.0`/`gio-2.0` by default. Breaking: Wayland screen sharing now requires the `glib-main-loop` feature on `livekit` (or `libwebrtc`). # libwebrtc 0.3.37 (2026-06-17) ## Features ### Add dynacast support - #1003 (@chenosaurus, @stephen-derosa) This includes a minor breaking change for `libwebrtc`: `RtpParameters` now contains additional RTP sender state that must be preserved when round-tripping through `set_parameters()`. ### Make GLib an opt-in dependency `webrtc-sys` no longer links against `glib-2.0`/`gobject-2.0`/`gio-2.0` by default.

SubscribedQualityUpdateevents from SFU and update published layers.Heres a video of dynacast working. We can see that if we get server commands down, we properly respond
