### Install dependencies and Chromium for headless server collection

Source: https://github.com/zxsos/hghubx/blob/main/docs/playback-diagnostics.md

Prerequisite setup for headless server auto-collection. Requires Node.js 22+, pnpm, FFmpeg (with libx264/AAC), and Chromium.

```sh
pnpm install --frozen-lockfile
pnpm exec playwright-core install --with-deps chromium
```

--------------------------------

### Run playback diagnostics tests

Source: https://github.com/zxsos/hghubx/blob/main/docs/playback-diagnostics.md

Generates 90-second HLS media, starts Vite/media server on random localhost port, operates headless browser, and cleans up after. External network requests are blocked and cause failure.

```sh
pnpm test:playback
```

--------------------------------

### 编译 sing-box 二进制规则集（sing-box rule-set compile）

Source: https://github.com/zxsos/hghubx/blob/main/rules/README.md

将 hghubx.json 编译为 hghubx.srs，供 sing-box 二进制规则集使用。编译后需将配置中的 format 改为 binary、path 改为 ./rules/hghubx.srs。

```sh
sing-box rule-set compile --output rules/hghubx.srs rules/hghubx.json

```

--------------------------------

### 生成本地 HLS fixture 并启动测试服务

Source: https://github.com/zxsos/hghubx/blob/main/docs/playback-seek.md

使用 ffmpeg 生成 90 秒 HLS 测试资源，然后启动本地代理服务。需要 FFmpeg 和 Python 3。

```sh
seek_fixture_dir=$(mktemp -d)
ffmpeg -hide_banner -loglevel error \
  -f lavfi -i testsrc2=size=320x180:rate=15 \
  -f lavfi -i sine=frequency=440:sample_rate=44100 -t 90 \
  -c:v libx264 -preset ultrafast -g 30 -sc_threshold 0 -pix_fmt yuv420p \
  -c:a aac -f hls -hls_time 2 -hls_playlist_type vod \
  -hls_segment_filename "$seek_fixture_dir/seg%03d.ts" "$seek_fixture_dir/list.m3u8"
python3 tests/serve-seek-media.py "$seek_fixture_dir"
```

--------------------------------

### Run limited playback regression scenarios

Source: https://github.com/zxsos/hghubx/blob/main/docs/playback-diagnostics.md

Executes only the specified scenarios (seek, legacy, stall) for focused diagnostics. Fails with exit code 1 on any check failure but retains logs and reports.

```sh
pnpm test:playback --scenarios seek,legacy,stall
```

--------------------------------

### sing-box 规则集配置（route 的 rule_set 与 rules）

Source: https://github.com/zxsos/hghubx/blob/main/rules/README.md

将 hghubx.json 作为 source 格式的本地规则集加入 route，并添加路由规则。适用于 sing-box 1.11+；1.10 需要删除路由项中的 action 字段。替换 proxy 为实际出站标签。

```json
{
  "route": {
    "rule_set": [
      {
        "type": "local",
        "tag": "hghubx",
        "format": "source",
        "path": "./rules/hghubx.json"
      }
    ],
    "rules": [
      {
        "rule_set": ["hghubx"],
        "action": "route",
        "outbound": "proxy"
      }
    ]
  }
}

```

--------------------------------

### Mihomo 规则集配置（rule-providers 与 rules）

Source: https://github.com/zxsos/hghubx/blob/main/rules/README.md

将 hghubx.list 作为 classical/text 规则集引入 Mihomo，并添加 RULE-SET 规则。需要把 PROXY 替换为已有代理组名，且规则应放在其他兜底规则之前。也可使用 type: http 并填写实际 url 和更新周期。

```yaml
rule-providers:
  hghubx:
    type: file
    behavior: classical
    format: text
    path: ./rules/hghubx.list

rules:
  - RULE-SET,hghubx,PROXY

```

--------------------------------

### Run MMS-specific diagnostics

Source: https://github.com/zxsos/hghubx/blob/main/docs/playback-diagnostics.md

Verifies hls.js MMS compatibility fix only. Uses Chromium's real MSE for decoding and buffering, simulates MMS constructors and streaming events. Report marks simulated_mms: true.

```sh
pnpm test:playback --scenarios mms
```
