+## Deploying aitube2 to https://aitube.at
+
+Note: this document is meant for aitube administrators only, not the general public.
+
+Aitube is not an app/tool but a website, it is not designed to be cloned (technically you can, but since this is not a goal it is not documented).
+
+### Setup the domain
+
+TODO
+
+### Seting up the Python virtual environment
+
+```bash
+python3 -m venv .python_venv
+source .python_venv/bin/activate
+python3 -m pip install --no-cache-dir --upgrade -r requirements.txt 
+```
+
+### Deployment to production
+
+To deploy the aitube2 api to production:
+
+    $ git push space main
+
+To deploy the aitube2 client to production, simply run:
+
+    $ flutter run web
+
+and upload the assets to:
+
+    https://huggingface.co/spaces/jbilcke-hf/aitube2/tree/main/public
+
+#### Running a rendering node
+
+Current aitube uses `jbilcke-hf/LTX-Video-0-9-6-HFIE` as a rendering node.
+
+aitube uses a round-robin schedule implemented on the gateway.
+This helps ensuring a smooth attribution of requests.
+
+What works well is to use the target number of users in parallel (eg. 3) and use 50% more capability to make sure we can handle the load, so in this case about 5 servers.
+
+```bash
+# note: you need to replace <YOUR_ACCOUNT_NAME>, <ROUND_ROBIN_INDEX> and <YOUR_HF_TOKEN>
+
+curl https://api.endpoints.huggingface.cloud/v2/endpoint/<YOUR_ACCOUNT_NAME> 	-X POST 	-d '{"cacheHttpResponses":false,"compute":{"accelerator":"gpu","instanceSize":"x1","instanceType":"nvidia-l40s","scaling":{"maxReplica":1,"measure":{"hardwareUsage":80},"minReplica":0,"scaleToZeroTimeout":120,"metric":"hardwareUsage"}},"model":{"env":{},"framework":"custom","image":{"huggingface":{}},"repository":"jbilcke-hf/LTX-Video-0-9-6-HFIE","secrets":{},"task":"custom","fromCatalog":false},"name":"ltx-video-0-9-6-round-robin-<ROUND_ROBIN_INDEX>","provider":{"region":"us-east-1","vendor":"aws"},"tags":[""],"type":"protected"}' 	-H "Content-Type: application/json" 	-H "Authorization: Bearer <YOUR_HF_TOKEN>"
+```
+
+#### Running the gateway scheduler
+
+```bash
+# load the environment
+# (if you haven't done it already for this shell session)
+source .python_venv/bin/activate
+
+HF_TOKEN="<USE YOUR OWN TOKEN>" \
+    SECRET_TOKEN="<USE YOUR OWN TOKEN>" \

+# AiTube2
+
+## News
+
+aitube2 is coming sooner than expected!
+
+Stay hooked at @flngr on X!
+
+
+## What is AiTube?
+
+AiTube 2 is a reboot of [AiTube 1](https://x.com/danielpikl/status/1737882643625078835), a project made in 2023 which generated AI videos in the background using LLM agents, to simulate an AI generated YouTube.
+
+In [AiTube 2](https://x.com/flngr/status/1864127796945011016), this concept is put upside down: now the content is generated on demand (when the user types something in the latent search input) and on the fly (video chunks are generated within a few seconds and streamed continuously).
+
+This allows for new ways of consuming AI generated content, such as collaborative and interactive prompting.
+
+# Where can I use it?
+
+AiTube 2 is not ready yet: this is an experimental side project and the [platform](https://aitube.at), code and documentation will be in development for most of 2025.
+
+# Why can't I use it?
+
+As this is a personal project I only have limited ressources to develop it on the side, but there are also technological bottlenecks.
+
+Right now it is not economically viable to operate a platform like AiTube, it requires hardware that is too expensive and/or not powerful enough to give an enjoyable and reactive streaming experience.
+
+I am evaluating various options to make it available sooner for people with the financial ressources to try it, such as creating a system to deploy render nodes to Hugging Face, GPU-on-demand blockchains.. etc.
+
+# When can I use it?
+
+I estimate it will take up to 1 to 2 years for more powerful and/or cheaper hardware to become available.
+
+I already have a open-source prototype of AiTube which I use for R&D, based on free (as in "can run on your own machine") AI video models that can run fast with low quality settings (such as LTX Video).
+
+It's not representative of the final experience, but that's a start and I use that as a basis to imagine the experiences of the future (collaborative generation, broadcasted live streams, interactive gaming, and artistic experiences that are hybrid between video and gaming).

+
+FVP [#](#fvp)
+=============
+
+A plugin for official [Flutter Video Player](https://pub.dev/packages/video_player) to support all desktop and mobile platforms, with hardware accelerated decoding and optimal rendering. Based on [libmdk](https://github.com/wang-bin/mdk-sdk). You can also create your own players other than official `video_player` with [backend player api](#backend-player-api)
+
+Prebuilt example can be download from artifacts of [github actions](https://github.com/wang-bin/fvp/actions).
+
+[More examples are here](https://github.com/wang-bin/mdk-examples/tree/master/flutter)
+
+project is create with `flutter create -t plugin --platforms=linux,macos,windows,android,ios -i objc -a java fvp`
+
+Features [#](#features)
+-----------------------
+
+*   All platforms: Windows x64(including win7) and arm64, Linux x64 and arm64, macOS, iOS, Android(requires flutter > 3.19 because of minSdk 21).
+*   You can choose official implementation or this plugin's
+*   Optimal render api: d3d11 for windows, metal for macOS/iOS, OpenGL for Linux and Android(Impeller support)
+*   Hardware decoders are enabled by default
+*   Dolby Vision support on all platforms
+*   Minimal code change for existing [Video Player](https://pub.dev/packages/video_player) apps
+*   Support most formats via FFmpeg demuxer and software decoders if not supported by gpu. You can use your own ffmpeg 4.0~7.1(or master branch) by removing bundled ffmpeg dynamic library.
+*   High performance. Lower cpu, gpu and memory load than libmpv based players.
+*   Support audio without video
+*   HEVC, VP8 and VP9 transparent video
+*   Small footprint. Only about 10MB size increase per cpu architecture(platform dependent).
+
+How to Use [#](#how-to-use)
+---------------------------
+
+*   Add [fvp](https://pub.dev/packages/fvp) in your pubspec.yaml dependencies: `flutter pub add fvp`. Since flutter 3.27, fvp must be a direct dependency in your app's pubspec.yaml.
+*   **(Optional)** Add 2 lines in your video\_player examples. Without this step, this plugin will be used for video\_player unsupported platforms(windows, linux), official implementation will be used otherwise.
+
+    import 'package:fvp/fvp.dart' as fvp;
+    
+    fvp.registerWith(); // in main() or anywhere before creating a player. use fvp for all platforms.
+    
+
+copied to clipboard
+
+You can also select the platforms to enable fvp implementation
+
+    registerWith(options: {'platforms': ['windows', 'macos', 'linux']}); // only these platforms will use this plugin implementation
+    
+
+copied to clipboard
+
+To select [other decoders](https://github.com/wang-bin/mdk-sdk/wiki/Decoders), pass options like this
+
+    fvp.registerWith(options: {
+        'video.decoders': ['D3D11', 'NVDEC', 'FFmpeg']
+        //'lowLatency': 1, // optional for network streams
+        }); // windows
+    
+
+copied to clipboard
+
+[The document](https://pub.dev/documentation/fvp/latest/fvp/registerWith.html) lists all options for `registerWith()`
+
+### Error Handling [#](#error-handling)
+
+Errors are usually produced when loading a media.
+
+    _controller.addListener(() {
+      if (_controller.value.hasError && !_controller.value.isCompleted) {
+        ...
+    
+
+copied to clipboard
+
+### Backend Player API [#](#backend-player-api)
+
+    import 'package:fvp/mdk.dart';
+    
+
+copied to clipboard
+
+The plugin implements [VideoPlayerPlatform](https://pub.dev/packages/video_player_platform_interface) via [a thin wrapper](https://github.com/wang-bin/fvp/blob/master/lib/video_player_mdk.dart) on [player.dart](https://github.com/wang-bin/fvp/blob/master/lib/src/player.dart).
+
+Now we also expose this backend player api so you can create your own players easily, and gain more features than official [video\_player](https://pub.dev/packages/video_player), for example, play from a given position, loop in a range, decoder selection, media information detail etc. You can also reuse the Player instance without unconditionally create and dispose, changing the `Player.media` is enough. [This is an example](https://github.com/wang-bin/mdk-examples/blob/master/flutter/simple/lib/multi_textures.dart)
+
+### VideoPlayerController Extensions [#](#videoplayercontroller-extensions)
+
+With this extension, we can leverage mature `video_player` code without rewriting a new one via backend player api, but gain more features, for example `snapshot()`, `record()`, `fastSeekTo()`, `setExternalSubtitle()`.
+
+    import 'package:fvp/fvp.dart' as fvp;
+    
+    fvp.registerWith(); // in main() or anywhere before creating a player. use fvp for all platforms.
+    
+    // somewhere after controller is initialized
+    _controller.record('rtmp://127.0.0.1/live/test');
+    
+
+copied to clipboard
+
+Upgrade Dependencies Manually [#](#upgrade-dependencies-manually)
+=================================================================
+
+Upgrading binary dependencies can bring new features and backend bug fixes. For macOS and iOS, in your project dir, run
+
+    pod cache clean mdk
+    find . -name Podfile.lock -delete
+    rm -rf {mac,i}os/Pods
+    
+
+copied to clipboard
+
+For other platforms, set environment var `FVP_DEPS_LATEST=1` and rebuilt, will upgrade to the latest sdk. If fvp is installed from pub.dev, run `flutter pub cache clean` is another option.
+
+Design [#](#design)
+===================
+
+*   Playback control api in dart via ffi
+*   Manage video renderers in platform specific manners. Receive player ptr via `MethodChannel` to construct player instance and set a renderer target.
+*   Callbacks and events in C++ are notified by ReceivePort
+*   Function with a one time callback is async and returns a future
+
+Enable Subtitles [#](#enable-subtitles)
+=======================================
+
+libass is required, and it's added to your app automatically for windows, macOS and android(remove ass.dll, libass.dylib and libass.so from mdk-sdk if you don't need it). For iOS, [download](https://sourceforge.net/projects/mdk-sdk/files/deps/dep.7z/download) and add `ass.framework` to your xcode project. For linux, system libass can be used, you may have to install manually via system package manager.
+
+If required subtitle font is not found in the system(e.g. android), you can add [assets/subfont.ttf](https://github.com/mpv-android/mpv-android/raw/master/app/src/main/assets/subfont.ttf) in pubspec.yaml assets as the fallback. Optionally you can also download the font file by fvp like this
+
+      fvp.registerWith(options: {
+        'subtitleFontFile': 'https://github.com/mpv-android/mpv-android/raw/master/app/src/main/assets/subfont.ttf'
+      });
+    
+
+copied to clipboard
+
+DO NOT use flutter-snap [#](#do-not-use-flutter-snap)
+=====================================================
+
+Flutter can be installed by snap, but it will add some [enviroment vars(`CPLUS_INCLUDE_PATH` and `LIBRARY_PATH`) which may break C++ compiler](https://github.com/canonical/flutter-snap/blob/main/env.sh#L15-L18). It's not recommended to use snap, althrough building for linux is [fixed](https://github.com/wang-bin/fvp/commit/567c68270ba16b95b1198ae58850707ae4ad7b22), but it's not possible for android.

+Video Player plugin for Flutter [#](#video-player-plugin-for-flutter)
+=====================================================================
+
+[![pub package](https://img.shields.io/pub/v/video_player.svg)](https://pub.dev/packages/video_player)
+
+A Flutter plugin for iOS, Android and Web for playing back video on a Widget surface.
+
+Android
+
+iOS
+
+macOS
+
+Web
+
+**Support**
+
+SDK 16+
+
+12.0+
+
+10.14+
+
+Any\*
+
+![The example app running in iOS](https://github.com/flutter/packages/blob/main/packages/video_player/video_player/doc/demo_ipod.gif?raw=true)
+
+Setup [#](#setup)
+-----------------
+
+### iOS [#](#ios)
+
+If you need to access videos using `http` (rather than `https`) URLs, you will need to add the appropriate `NSAppTransportSecurity` permissions to your app's _Info.plist_ file, located in `<project root>/ios/Runner/Info.plist`. See [Apple's documentation](https://developer.apple.com/documentation/bundleresources/information_property_list/nsapptransportsecurity) to determine the right combination of entries for your use case and supported iOS versions.
+
+### Android [#](#android)
+
+If you are using network-based videos, ensure that the following permission is present in your Android Manifest file, located in `<project root>/android/app/src/main/AndroidManifest.xml`:
+
+    <uses-permission android:name="android.permission.INTERNET"/>
+    
+
+copied to clipboard
+
+### macOS [#](#macos)
+
+If you are using network-based videos, you will need to [add the `com.apple.security.network.client` entitlement](https://flutter.dev/to/macos-entitlements)
+
+### Web [#](#web)
+
+> The Web platform does **not** support `dart:io`, so avoid using the `VideoPlayerController.file` constructor for the plugin. Using the constructor attempts to create a `VideoPlayerController.file` that will throw an `UnimplementedError`.
+
+\* Different web browsers may have different video-playback capabilities (supported formats, autoplay...). Check [package:video\_player\_web](https://pub.dev/packages/video_player_web) for more web-specific information.
+
+The `VideoPlayerOptions.mixWithOthers` option can't be implemented in web, at least at the moment. If you use this option in web it will be silently ignored.
+
+Supported Formats [#](#supported-formats)
+-----------------------------------------
+
+*   On iOS and macOS, the backing player is [AVPlayer](https://developer.apple.com/documentation/avfoundation/avplayer). The supported formats vary depending on the version of iOS, [AVURLAsset](https://developer.apple.com/documentation/avfoundation/avurlasset) class has [audiovisualTypes](https://developer.apple.com/documentation/avfoundation/avurlasset/1386800-audiovisualtypes?language=objc) that you can query for supported av formats.
+*   On Android, the backing player is [ExoPlayer](https://google.github.io/ExoPlayer/), please refer [here](https://google.github.io/ExoPlayer/supported-formats.html) for list of supported formats.
+*   On Web, available formats depend on your users' browsers (vendor and version). Check [package:video\_player\_web](https://pub.dev/packages/video_player_web) for more specific information.

+
+Usage [#](#usage)
+-----------------
+
+The following section contains usage information that goes beyond what is included in the documentation in order to give a more elaborate overview of the API.
+
+This is not complete as of now. You can contribute to this section by [opening a pull request](https://github.com/flutter/packages/pulls).
+
+### Playback speed [#](#playback-speed)
+
+You can set the playback speed on your `_controller` (instance of `VideoPlayerController`) by calling `_controller.setPlaybackSpeed`. `setPlaybackSpeed` takes a `double` speed value indicating the rate of playback for your video. For example, when given a value of `2.0`, your video will play at 2x the regular playback speed and so on.
+
+To learn about playback speed limitations, see the [`setPlaybackSpeed` method documentation](https://pub.dev/documentation/video_player/latest/video_player/VideoPlayerController/setPlaybackSpeed.html).
+
+Furthermore, see the example app for an example playback speed implementation.
