# LibTV - Image & Video Generation (Seedance 2.0)

Generate AI **images** and **videos** through one bundled LibTV skill, powered by Seedance 2.0. Supports text-to-image, image-to-image, text-to-video, and image-to-video workflows, via both Nexu-managed Seedance execution and direct LibTV execution with a user-owned `sk-libtv-...` key.

Key routing:

- `mgk_...` keys use Nexu-managed Seedance through `https://seedance.nexu.io/`
- `sk-libtv-...` keys use direct LibTV OpenAPI through `https://im.liblib.tv`

Delivery architecture (currently Feishu only):
- `create-session` captures `OPENCLAW_CHANNEL_TYPE` + `OPENCLAW_CHAT_ID`,
  persists them as the session's `delivery` block, forks a detached
  `wait-and-deliver` background process via `subprocess.Popen(...,
  start_new_session=True)`, and returns immediately with a single-line
  JSON submit confirmation on stdout.
- The forked waiter polls the upstream LibTV API (Seedance gateway or
  direct LibTV) and, on terminal success, shells out to
  `feishu_send_video.py`, the same proven helper used by `medeo-video`, which downloads each result URL, uploads it to Feishu's file API, and
  posts a native media message to the originating chat.
- The waiter's output is captured in `$NEXU_HOME/libtv-waiter-<id>.log`
  for post-hoc debugging. A `delivered_at` timestamp is persisted when
  the Feishu helper reports success, so re-invoking `wait-and-deliver`
  on a delivered session is a safe no-op.

No `sessions_spawn`, no subagent model-speech contract, no HTTP
notification callback, no stale routing fields. Delivery is a direct
HTTP call using stable per-user identifiers (`open_id` / `chat_id`)
that never go stale the way the old `account_id` did.

Multi-channel support is a follow-up: adding Discord / Slack / WeChat
means dropping a new `<channel>_send_video.py` helper next to
`feishu_send_video.py` and adding one branch in `_deliver_results`.
