WalkthroughThe change removes the gst-base dependency and refactors MoqSink to extend gst::Element instead of gst_base::BaseSink. MoqSink's internal state shifts from Arc<Mutex> to Mutex<Option> and adds per-pad decoding with request-based pads. New methods include change_state, request_new_pad, and release_pad. The justfile introduces RUST_LOG defaults, adds GST_PLUGIN_PATH_1_0, and updates pipelines to use parsebin and moqsrc. Documentation and examples rename hang*/hangsrc/hangsink terminology to moq*/moqsrc/moqsink and adjust TLS/configuration and environment variable descriptions. 🚥 Pre-merge checks | ❌ 3❌ Failed checks (2 warnings, 1 inconclusive)

14-20: Consider usingnew_current_thread()for true single-threaded runtime.The coding guidelines specify "single-threaded Tokio worker pool." Using
new_multi_thread()withworker_threads(1)creates a multi-threaded runtime constrained to one worker, which has different semantics thannew_current_thread()(e.g., spawns a separate thread pool even with one worker).♻️ Suggested change
pub static RUNTIME: LazyLock<tokio::runtime::Runtime> = LazyLock::new(|| { - tokio::runtime::Builder::new_multi_thread() + tokio::runtime::Builder::new_current_thread() .enable_all() - .worker_threads(1) .build() .unwrap() });Based on learnings: "Use single-threaded Tokio worker pool for async runtime in plugin elements".

286-302: Consider logging when using default Opus parameters.When
channelsorrateare not present in caps, the code silently falls back to defaults (2 channels, 48000 Hz). This could produce incorrect OpusHead if the actual stream differs. A debug log would help diagnose issues.💡 Suggested enhancement

Inline comments:
In `@CLAUDE.md`:
- Line 87: The documentation line referencing GST_PLUGIN_PATH is out of sync
with the justfile which now uses GST_PLUGIN_PATH_1_0; update the CLAUDE.md entry
that currently says `GST_PLUGIN_PATH` to instead mention `GST_PLUGIN_PATH_1_0`
(or document both with a note that the justfile sets GST_PLUGIN_PATH_1_0) so the
docs and the justfile are consistent.
In `@src/sink/imp.rs`:
- Around line 282-284: The code currently calls map_readable().unwrap() which
can panic; replace the unwrap with proper error propagation by using
map_readable()? (or match/map_err to convert the mapping error into the
function's error type) and handle the Result before creating bytes::Bytes and
calling decoder.initialize(&mut data)?; update the variables map and data
accordingly so mapping failures return an error instead of panicking (affecting
the map_readable, data, and decoder.initialize calls).
