fix(moq-audio,moq-video): build capture and Android again, and gate both on PRs by Frando · Pull Request #3850 · moq-dev/moq

Frando · 2026-09-21T15:19:49Z

main does not build moq-audio or moq-video with the capture feature, and it does not build moq-video for Android. No pull-request job compiles either configuration, which is how both breaks got in. This PR fixes both and adds the two gates that would have caught them.

Fixes

Capture. feat(hang)!: unify catalog APIs #3813 renamed Clock::micros() -> u64 to Clock::now() -> Timestamp. It missed moq-audio's encode/capture.rs and moq-video's encode/producer.rs, which are both behind capture. Nightly's macOS job reported this after the merge.
Android. The encoder's resolved bitrate became a bandwidth::Rate, but mediacodec.rs still passes it to a u64 helper. Nothing compiles that file off Android.

CI

Capture gate. check-changed runs a new just rs capture whenever moq-video or moq-audio is selected. That lints both crates with capture under -D warnings. Selection includes dependents, so a moq-mux or moq-net diff also reaches it. _select-test asserts that a moq-mux diff drives the gate and a moq-relay diff doesn't.
Android gate. android.yml runs the existing just rs android recipe on ubuntu-24.04, outside Nix, because the dev shell has no NDK and the runner image has one. It triggers on moq-video's in-repo dependency graph, the same way wasm.yml is scoped.
Not covered. Apple and Windows stay nightly-only, and nightly failures still land on main.
Unrelated nightly break. The nightly features step currently fails at its first command. The lan_mesh test doesn't compile with --no-default-features, so the step's all-features clippy never runs. That break is unrelated and not fixed here.

Verification

I reverted each fix locally and ran the matching gate. just rs capture fails on Clock::micros, and just rs android fails on the Rate mismatch. Both pass with the fixes.
just rs _select-test passes.
android.yml passes on this PR in about three minutes. cargo-ndk finds the runner image's NDK through ANDROID_NDK_HOME with no extra setup.

🤖 Generated with Claude Code

…ed Clock moq-dev#3813 replaced `moq_mux::Clock::micros() -> u64` with `Clock::now() -> Timestamp`, and updated every caller except the two behind the `capture` feature. `cargo check -p moq-audio --features capture` and the same for moq-video fail on `main` as a result, and nothing in CI builds that feature, so it went unnoticed. The video producer wanted a `Timestamp` anyway and was converting into one, so it now takes `clock.now()` directly and loses a fallible conversion with it. The audio capture path feeds a converter that counts in microseconds, so it reads `now().as_micros()`, which is what `micros()` computed before. `moq_net::Timestamp` in the video producer is left needed only by its tests, so its import narrows to `cfg(test)`.

The encoder's resolved bitrate became a bandwidth `Rate`, and the Android backend still handed it to a helper that takes a plain `u64`. The file is only compiled for Android, so no host build caught it; moq-video failed to build for any Android target. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

…ests Both fixes before this one are for code no pull-request job compiles. The device code in moq-video and moq-audio sits behind the off-by-default `capture` feature, and moq-video's MediaCodec backend behind `target_os = "android"`. The Linux gate compiles neither, so moq-dev#3813's Clock rename and the move to `bandwidth::Rate` both reached main with their callers broken. Nightly's macOS job did report the first, after the merge. `check-changed` now runs a new `capture` recipe whenever moq-video or moq-audio is selected. Selection includes dependents, so a moq-mux or moq-net diff reaches it, and `_select-test` asserts that a moq-mux diff does and a moq-relay diff does not. It lints just those two crates with `capture`, not `--all-features`, which would also build the bindgen codecs nightly already covers. android.yml runs the existing `just rs android` recipe on an ubuntu runner, outside Nix because the dev shell has no NDK and the runner image does. It triggers on moq-video's in-repo dependency graph. Checked by reverting each fix: `just rs capture` fails on `Clock::micros`, and `just rs android` fails on the `Rate` mismatch. Both pass with the fixes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

We should probably make it a default feature?

Walkthrough

Added an Android GitHub Actions workflow for scoped pull requests. The workflow installs pinned tools and the Android target, then runs just rs android. Added capture-feature selection and clippy validation for moq-video and moq-audio. Updated capture timestamp and bitrate call sites for current APIs.

Use a pull-request-stable concurrency key.

For an active pull request, github.ref uses the pull-request merge ref. For a merged closed event, it uses the target branch ref. These values produce different concurrency groups, so the close event cannot cancel the active run. The job-level if does not prevent workflow-level concurrency cancellation.

Keeping capture opt-in for now, so landing as-is:

render is already default in moq-video (default = [mediacodec, nvidia, render]).
capture stays opt-in because on Linux it needs libclang + kernel headers (v4l bindgen over videodev2.h) and libasound (cpal). Making it default would force those system deps on every default build, including CI just check, the relay, and downstream consumers unless they opt out via default-features = false.
This PR fixes the actual gap (no PR job compiled capture or Android) with the just rs capture gate and android.yml, so the breaks can't recur without changing defaults.

Follow-up: open a quest to see if those system deps can be removed or narrowed so capture could become default later.

moq-dev/moq#3850 merged the capture and Android build fixes that `Frando/moq@iroh-live-4` carried, so the fork is no longer needed. The patch block points at upstream `main`, pinned by `Cargo.lock` at 6ab7d1a2. The 24 commits since our previous base need no changes here: the workspace, the Android crates, clippy and the full test suite are all clean against them. The block itself stays until moq releases something after the `dev` merge; its comment now says only that. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
