# Extension points — harry0703/MoneyPrinterTurbo

Scanned commit 3d5f4e421927d61f3eac729cf4b711ac0b69d688 (2026-09-21). Generated by codevetter codevetter 1.12.0 on 2026-09-22.

The codebase is deliberately registry/dispatch oriented. New LLM providers plug into LLM_PROVIDER_REGISTRY plus (only for non-OpenAI-compatible protocols) an adapter branch in llm._generate_response. New video material sources extend the download_videos dispatch plus the CLI's _CLI_VIDEO_SOURCES and mpt_agent's SUPPORTED_SOURCES. New AI-music providers slot into _VIDEO_MUSIC_PROVIDERS. New TTS engines add is_*_voice detectors and a _single_tts branch. State and queue backends are subclassable, routes extend via new_router, and UI strings via i18n JSON files.
- LLM providers: append an LLMProviderSpec to LLM_PROVIDER_REGISTRY (provider_id, defaults, endpoints, extra_fields); OpenAI-compatible providers need no adapter code — only gemini, qwen, azure, claude_code, litellm have dedicated branches in _generate_response. — [app/models/llm_provider.py#L29-195](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/models/llm_provider.py#L29-L195) [app/services/llm.py#L257-331](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/services/llm.py#L257-L331)
- Video material sources: add a branch in material.download_videos plus the source id in cli.py's _CLI_VIDEO_SOURCES, docs/skill/mpt_agent.py's SUPPORTED_SOURCES (kept aligned by comment), and config.example.toml keys; WebUI-specific sources like loomloom bypass download_videos entirely via get_video_materials in task.py. — [app/services/material.py#L1686-1805](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/services/material.py#L1686-L1805) [cli.py#L37-51](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/cli.py#L37-L51) [docs/skill/mpt_agent.py](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/docs/skill/mpt_agent.py) [app/services/task.py#L648-728](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/services/task.py#L648-L728)
- AI music providers: register in task.py's _VIDEO_MUSIC_PROVIDERS dict — a service module implementing is_enabled() and generate_bgm() plus error_type/suffix/warning_code/display_name metadata; orchestration, zero-volume short-circuit, and failure degradation are shared. — [app/services/task.py#L72-103](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/services/task.py#L72-L103)
- TTS engines: add an is_<name>_voice() detector on the voice-name prefix and a dispatch branch in _single_tts; voice lists surface via get_<name>_voices() helpers consumed by the WebUI. — [app/services/voice.py#L379-460](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/services/voice.py#L379-L460) [app/services/voice.py#L597-728](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/services/voice.py#L597-L728)
- Subtitle engines: config.app.subtitle_provider selects among 'edge', 'whisper', or empty inside task.generate_subtitle — adding a provider means a new branch there plus a service module like subtitle.py. — [app/services/task.py#L580-645](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/services/task.py#L580-L645) [config.example.toml#L426-429](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/config.example.toml#L426-L429)
- State backends: subclass BaseState (update_task/get_task/get_all_tasks/patch_task/delete_task) and switch the singleton at the bottom of state.py; queue backends subclass TaskManager's create_queue/enqueue/dequeue/is_queue_empty/queue_size. — [app/services/state.py#L24-41](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/services/state.py#L24-L41) [app/services/state.py#L231-244](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/services/state.py#L231-L244) [app/controllers/manager/base_manager.py#L41-139](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/controllers/manager/base_manager.py#L41-L139)
- API surface: create a router with controllers/v1/base.new_router(dependencies=[Depends(base.verify_token)]) and include it in app/router.py — the pattern automatically yields /api/v1 prefix, V1 tag, and auth. — [app/controllers/v1/base.py](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/controllers/v1/base.py) [app/router.py](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/router.py) [app/controllers/v1/llm.py#L16-18](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/controllers/v1/llm.py#L16-L18)
- Cross-post platforms: extend upload_post_platforms config values plus the _CROSS_POST_SOCIAL_PLATFORMS map in task.py that translates platform ids into LLM social-metadata platform names. — [app/services/task.py#L66-71](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/services/task.py#L66-L71) [app/services/upload_post.py#L30-35](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/services/upload_post.py#L30-L35) [config.example.toml#L477-478](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/config.example.toml#L477-L478)
- UI languages: drop a new locale JSON into webui/i18n/ — utils.load_locales scans the directory at startup; locale keys like llm_provider_label.<id> are referenced by the provider registry. — [webui/i18n/en.json](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/webui/i18n/en.json) [app/utils/utils.py#L535-547](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/utils/utils.py#L535-L547) [app/models/llm_provider.py#L58-79](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/models/llm_provider.py#L58-L79)
- Config schema: add keys under config.example.toml sections and read them via config.<section>.get(); entirely new sections require adding a dict to save_config's serialization list or they will be dropped on save. — [app/config/config.py#L492-504](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/config/config.py#L492-L504) [config.example.toml](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/config.example.toml)
- Pipeline parameters: new VideoParams fields automatically flow into API request models (TaskVideoRequest subclasses VideoParams) and CLI batch manifests (unknown fields rejected, known fields merged), but CLI single-task flags must be added manually to parse_args. — [app/models/schema.py#L255-256](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/models/schema.py#L255-L256) [cli.py#L287-298](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/cli.py#L287-L298)
- FFmpeg encoder options are config-driven: app.video_codec accepts libx264/h264_nvenc/h264_amf/h264_qsv/h264_mf/h264_videotoolbox with runtime probing and automatic fallback — new encoders plug into _get_effective_video_codec's probe path. — [app/services/video.py#L282-365](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/app/services/video.py#L282-L365) [config.example.toml#L436-440](https://github.com/harry0703/MoneyPrinterTurbo/blob/3d5f4e421927d61f3eac729cf4b711ac0b69d688/config.example.toml#L436-L440)
