# ECP-0020: deterministic encode checks + MoQ self-test CLI
|
|
|
|
## Status
|
|
Draft
|
|
|
|
## Context
|
|
We need a repeatable way to validate deterministic encoding and to verify MoQ publish/subscribe flows from the CLI without the UI.
|
|
|
|
## Decision
|
|
Add CLI tooling for (1) deterministic re-encoding checks using the libx264 single-thread profile, and (2) a local MoQ round-trip self-test that compares object hashes.
|
|
|
|
## Details
|
|
- `ec-cli determinism-test` re-encodes the same input multiple times using `deterministic_h264_profile` and compares segment hashes.
|
|
- `ec-node moq-selftest` publishes a chunked stream and subscribes to it using a second endpoint, verifying object hashes per chunk index.
|
|
- The self-test waits for the subscriber to acknowledge each published chunk to avoid MoQ track drops, and waits briefly for endpoint addresses to appear.
|
|
- Defaults are conservative: single-thread x264, bitexact flags, fixed GOP.
|
|
|
|
## Consequences
|
|
- Determinism regressions are detectable early.
|
|
- MoQ path can be validated headlessly without the Tauri app.
