wjs-uploading-video
Push finished videos to YouTube. Defaults are tuned for this user's workflow (王建硕 channel, China network with local proxy, 1080p horizontal recordings from Riverside / multicam edits).
When to use
- User has one or more finished
.mp4 files and wants them on YouTube
- User points to a
final/ directory with multiple segments and an UPLOAD_META.md
- User wants a specific privacy / playlist / scheduled publish
Don't use for:
- 微信视频号 upload (no public API; user uploads manually via web)
- 抖音 / 小红书 / B 站 (different APIs, not yet implemented here)
- YouTube Shorts variants from horizontal source (use
wjs-reframing-video first to produce the 9:16 cut, then upload that via this skill)
Prerequisites (one-time per machine)
- Google Cloud OAuth client:
~/.config/youtube/credentials.json must exist. See references/credentials-setup.md for the 5-minute setup if missing.
- Python deps:
pip3 install google-auth-oauthlib google-api-python-client requests (only google-auth + requests are strictly needed at upload time, but the OAuth-lib pulls them).
- First-ever upload opens a browser for Google consent and writes
~/.config/youtube/token.json. Subsequent runs reuse it silently.
How it works (and why it's not the stock youtube-uploader)
YouTube's resumable upload protocol issues a Location: URL after the metadata POST, then accepts the bytes in chunked PUT requests. The stock google-api-python-client runs this over httplib2, which under this user's local SOCKS+HTTP proxy stack throws [Errno 65] No route to host or socket.timeout on those follow-up PUTs and stalls indefinitely.
This skill bypasses httplib2: it does OAuth via google-auth, then drives the resumable upload manually with requests, passing the proxy explicitly. 8 MB chunks (not the stock 256 KB) — fewer round-trips through the proxy. Exponential-backoff retry on socket.timeout / ConnectionError / 5xx.
If you're tempted to "just call the YouTube API client directly," don't — it'll fail in this environment.
ModuleNotFoundError: No module named 'google.oauth2' — Homebrew 升级 Python 大版本后 site-packages 会丢（2026-08 从 3.13→3.14 实际发生过）。别重新 pip install，直接用 uvx 带依赖跑（已验证）：
uvx --with google-auth --with requests python \
~/.claude/skills/wjs-uploading-video/scripts/upload_youtube.py --dir "/path/to/final"
Usage
Batch upload a final/ directory
python3 ~/.claude/skills/wjs-uploading-video/scripts/upload_youtube.py \
--dir "/path/to/final" \
--meta "/path/to/final/UPLOAD_META.md"
The script:
- Reads
UPLOAD_META.md and pairs each ## NN · filename.mp4 block to a video file in --dir
- Skips videos already in
--results-file (default <dir>/.youtube_upload_results.json) — safe to re-run after failures
- Uploads sequentially with progress every 8 MB
- Writes the final URL list to
--results-file
Single file
python3 ~/.claude/skills/wjs-uploading-video/scripts/upload_youtube.py \
--video /path/to/clip.mp4 \
--title "My Title" \
--description "Body text" \
--tags "tag1,tag2,tag3"
Common overrides
| Flag | Default | Notes |
|---|
--privacy | public | private / unlisted / public |
--category | 28 | 28 = Science & Tech. 27 = Education. 24 = Entertainment. |
--made-for-kids | false | YouTube requires this declaration |
--playlist <ID> | none | Add each uploaded video to a playlist |
--publish-at <ISO8601> | none | Schedule publish (requires --privacy private) |
--credentials | ~/.config/youtube/credentials.json | OAuth client JSON |
--token | ~/.config/youtube/token.json | Cached OAuth token |
--chunk-mb | 8 | Smaller chunks if uploads keep failing mid-flight |
--dry-run | off | Parse meta + list what would upload, don't touch network |
UPLOAD_META.md format
The parser expects the user's standard structure:
## 01 · segment_01_no-bugs.mp4
**短标题**
代码没有错误,只有意图不一致
**视频描述**
AI 时代屎山的重新定义...
—— 王建硕 × 任鑫《...》第 1 集
#王建硕 #AI编程 #ClaudeCode
---
Mapping:
## NN · <filename> → which video this block describes**短标题** (or **Title**) block → YouTube title, verbatim. Short titles work but consider that YouTube allows up to 100 chars — if you want a richer title with series name, write it that way in **短标题****视频描述** (or **Description**) block → YouTube description, verbatim, with the #tag hashtags retained at the bottom- All
#word tokens in the 视频描述 → comma-separated YouTube tags (each # is stripped; the user's channel name 王建硕 is auto-prepended per global instructions)
Filename in the heading must match an actual file in --dir. If a file exists but has no meta block, the script errors loudly — pass --allow-missing-meta to upload it with --title <basename> and empty description.
Sensible defaults this skill bakes in
- Privacy = public: videos go live immediately and appear in subscriber feeds + search. Override per call with
--privacy unlisted (link-only) or --privacy private (owner-only) when you want to review first
- Category = 28 (Science & Tech): matches 王建硕 channel's main content; override with
--category per upload
- selfDeclaredMadeForKids = false: YouTube requires this; the user's content is adult-targeted
- Chunk size = 8 MB: validated working size through this user's local proxy (256 KB stalled)
- Skip already-uploaded: results file is the source of truth; deleting it forces re-upload
Channel-name CTA rule
If you write description footers, signatures, or "subscribe to me" lines into a video's metadata, use 王建硕 (the user's channel name). Don't put a guest's name there — guests like 任鑫 belong inside the description body when they're the conversation partner, never in the channel-CTA slot.
Troubleshooting
| Symptom | Fix |
|---|
access_denied 403 on consent screen | Add user's Google account to the OAuth client's Test users list in Google Cloud Console |
[Errno 65] No route to host mid-upload | Almost always a proxy issue — verify curl --max-time 10 https://upload.googleapis.com/upload/youtube/v3/videos returns a 4xx (any 4xx = proxy reachable); if 000, the proxy is down |
| Upload stalls with no progress lines | The proxy is silently buffering. Lower --chunk-mb 4 or restart the proxy daemon |
quotaExceeded (API units) | YouTube Data API default quota is 10,000 units/day, each upload is 1,600 units — so ~6 uploads/day. Request a quota bump in Google Cloud Console, or split uploads across days |
429 rateLimitExceeded · Video Uploads per day | A DIFFERENT, separate limit from API units — YouTube's per-project daily video-upload count (anti-abuse, tied to project verification status; can be very low). When hit, every upload in the batch fails init session failed: 429, none succeed. It is NOT a proxy/auth problem and can't be worked around. It resets at midnight US Pacific Time (not your local midnight). Options: wait for the PT reset and re-run (the results file was cleared so all retry); or upload via the YouTube Studio web UI, which does NOT consume this API limit; or get the GCP project verified to raise the cap. Earlier uploads the same PT-day (even manual API ones) eat into this count. |
| Token refresh fails | Delete ~/.config/youtube/token.json and re-run; OAuth browser flow restarts |
After uploading
- Results saved to
--results-file (JSON: file, title, video id, URL)
- Echo the URL list back to the user in a markdown table
- Videos are
public by default — they're live the moment the upload completes. If the user wanted a review buffer, mention they can re-upload with --privacy unlisted (or flip back to unlisted in YouTube Studio)
- If they mentioned a 合集 / series, offer to create a YouTube playlist and batch-add the new uploads (the user must give a playlist ID or let you create one)
