x265-only relauncher; STATE: the 16:51 stop was a machine reboot
- run/relaunch_x265.sh: start ONLY the x265 tier. run/relaunch_tiers.sh hardcodes `for t in x265 nvenc`, and the nvenc tier must not start while another job owns the GPU (the TubeSync 58-file repair batch holds it since 2026-10-09 20:36). x265 is pinned to the E-cores, so it shares only the RaiDrive mount -- 2 concurrent share jobs is the documented safe limit. - The launcher redirects its own banners into the log (under -WindowStyle Hidden, stdout goes nowhere) and documents the -ArgumentList form: the script path alone. - STATE.md: LastBootUpTime 2026-10-09 16:51:58 -- both tiers stopped by a REBOOT, not a bug (x265 404/589, nvenc 308/589); the stale lock pids need no cleanup because transcode.Lock is staleness-aware. Memory after reboot: 13 GB free / 50.3 of 55.9 GB committed, but the commit limit fell from 79.6 GB because D: is 92% full.

## 现在在跑什么
|
||||
|
||||
**两档都停着** —— 2026-10-09 11:30 业主叫停，先修 bug 再重启；进程已按 PID 全部清掉，GPU encoder 0 %。
|
||||
**重启前先读「第 10 个 bug：MemoryError」和「8 个 `.new.mp4` 残留」两节**，并先腾内存。
|
||||
|
||||
原设计：两个 HEVC 档在跑，各自独立的锁（`run-x265.lock` / `run-nvenc.lock`；x265 = E 核，nvenc = GPU ASIC，互不争抢）。
|
||||
|
||||
**它们不在 Hermes 的进程管理里** → `process_manage` 看不到，也没有退出通知：只能看日志、按 PID 杀。
|
||||
**只有 x265 一档在跑**（2026-10-09 20:51:41 起，单档启动器 `run/relaunch_x265.sh`）。
|
||||
**nvenc 档故意不启动** —— GPU 被 TubeSync 的 58 个文件修复批次占着（20:36 起，与铁律一致：同一颗编码器不能两个任务）。
|
||||
|
||||
```bash
|
||||
# 断点续跑（幂等：已转好的自动跳过，失败项文件未动，下一轮自动重做），每档最多重试 8 次
|
||||
bash /d/tmp/xcode/relaunch_tiers.sh
|
||||
|
||||
# 看进度
|
||||
tail -f /d/tmp/xcode/run_x265.log /d/tmp/xcode/run_nvenc.log
|
||||
# 只起 x265（E 核，纯 CPU）—— 仓库源 run/relaunch_x265.sh 拷到 /d/tmp/xcode/ 再跑
|
||||
powershell -NoProfile -Command 'Start-Process -FilePath "C:\Program Files\Git\bin\bash.exe" -ArgumentList "D:/tmp/xcode/relaunch_x265.sh" -WindowStyle Hidden'
|
||||
# ⚠ 参数必须只有脚本路径；写成 -ArgumentList "-lc","bash <脚本>" 会起一个交互式 bash，什么都不跑
|
||||
tail -f /d/tmp/xcode/run_x265.log
|
||||
```
|
||||
|
||||
### 2026-10-09 16:51:58：两档是**整机重启**停的，不是 bug
|
||||
|
||||
（两档都不在 Hermes 的进程管理里 → `process_manage` 看不到，也没有退出通知：只能看日志，按 PID 杀。）
|
||||
`LastBootUpTime = 2026-10-09 16:51:58`；x265 日志停在 16:50:42（404/589）、nvenc 停在 16:51:30
|
||||
（308/589）。11:48 由 relauncher 重新拉起、跑到重启为止。锁文件里那两个 PID（23792 / 50128）已是死号 ——
|
||||
`transcode.Lock` 是**过期感知**的（age > 300 s 且 pid 已死即接管），不需要手工清锁。
|
||||
|
||||
重启后内存正常：物理空闲 12.9–13 GB、提交 50.3/55.9 GB（11:19 那次 MemoryError 时是 96.5%）。
|
||||
⚠ 但提交上限从 79.6 GB 缩到 55.9 GB：D: 已 92% 满，pagefile 长不上去。
|
||||
|
||||
### 为什么改成"脱管"启动 —— 10:37 那次全停的教训（第 9 个 bug）
|
||||
|
||||
上一轮的 x265 / nvenc 是 Hermes 后台进程。**用户停会话时它们被一起杀了**：两个都停在编码到一半

# Start ONLY the x265 tier of the 樊登读书会 conversion, DETACHED from Hermes.
|
||||
#
|
||||
# Why a separate launcher: run/relaunch_tiers.sh hardcodes `for t in x265 nvenc`, and the nvenc
|
||||
# tier must NOT start while another job owns the GPU -- the TubeSync 58-file repair batch has held
|
||||
# the GPU encoder since 2026-10-09 20:36. x265 is pure CPU pinned to the E-cores (0x3FF0000), so it
|
||||
# shares nothing with the GPU job; the only shared resource is the RaiDrive mount, and 2 concurrent
|
||||
# share jobs is the documented safe limit (3 produced `[Errno 9] Bad file descriptor`).
|
||||
#
|
||||
# Detached for the reason recorded in STATE.md: a Hermes-scoped background job is killed when the
|
||||
# session ends (measured 2026-10-08 10:37, both tiers killed mid-encode), so the launcher is started
|
||||
# by `powershell Start-Process ... -WindowStyle Hidden` and its parent exits immediately. No exit
|
||||
# notification -- watch the log; stop by PID only, never by image name.
|
||||
#
|
||||
# Idempotent: already-converted files are skipped, a failure leaves the live file untouched and the
|
||||
# next attempt retries it. Lock: C:\AI\transcode-run\run-x265.lock (stale-aware: age > 300 s AND a
|
||||
# dead pid is taken over automatically, so the lock left by the 16:51 reboot needs no cleanup).

# Start-Process -FilePath "C:\Program Files\Git\bin\bash.exe" -ArgumentList "<this script>" -WindowStyle Hidden
