## Code of conduct
This project and everyone participating in it is governed by the [api.video Code of Conduct](https://github.com/apivideo/.github/blob/main/CODE_OF_CONDUCT.md). By participating, you are expected to uphold this code. Please report unacceptable behavior to [help@api.video](mailto:help@api.video).
## I just have a question!
> **Note:** [Please don't file an issue to ask a question.] You'll get faster results by using the resources below.
We have an official message board with a detailed FAQ and where the community chimes in with helpful advice if you have questions.
* [The official api.video's Community](https://community.api.video/)
* [api.video FAQ](https://community.api.video/c/faq/)
## How can I contribute?
### Reporting bugs
This section guides you through submitting a bug report for api.video. Following these guidelines helps maintainers and the community understand your report :pencil:, reproduce the behavior :computer:, and find related reports :mag_right:.
Before creating bug reports, please check [this list](#before-submitting-a-bug-report) as you might find out that you don't need to create one. When you are creating a bug report, please [include as many details as possible](#how-do-i-submit-a-good-bug-report). Fill out [the required template](https://github.com/apivideo/.github/blob/main/.github/ISSUE_TEMPLATE/bug_report.yml), the information it asks for helps us resolve issues faster.
> **Note:** If you find a **Closed** issue that seems like it is the same thing that you're experiencing, open a new issue and include a link to the original issue in the body of your new one.
#### Before submitting a bug report
* **Check the [The official api.video's Community](https://community.api.video/)** for a list of common questions and problems.
* **Determine which repository the problem should be reported in**.
* **Perform a [cursory search](https://github.com/search?q=is%3Aissue+user%3Aapivideo)** to see if the problem has already been reported. If it has **and the issue is still open**, add a comment to the existing issue instead of opening a new one.
#### How do I submit a (good) bug report?
Bugs are tracked as [GitHub issues](https://guides.github.com/features/issues/). After you've determined which repository your bug is related to, create an issue on that repository and provide the following information by filling in [the template](https://github.com/apivideo/.github/blob/main/.github/ISSUE_TEMPLATE/bug_report.yml).
Explain the problem and include additional details to help maintainers reproduce the problem:
* **Use a clear and descriptive title** for the issue to identify the problem.
* **Describe the exact steps which reproduce the problem** in as many details as possible. When listing steps, **don't just say what you did, but explain how you did it**.
* **Provide specific examples to demonstrate the steps**. Include links to files or GitHub projects, or copy/pasteable snippets, which you use in those examples. If you're providing snippets in the issue, use [Markdown code blocks](https://help.github.com/articles/markdown-basics/#multiple-lines).
* **Describe the behavior you observed after following the steps** and point out what exactly is the problem with that behavior.
* **Explain which behavior you expected to see instead and why.**
* **Include screenshots or videos** which show you following the described steps and clearly demonstrate the problem.
* **If the problem wasn't triggered by a specific action**, describe what you were doing before the problem happened and share more information using the guidelines below.
Provide more context by answering these questions:
* **Did the problem start happening recently** (e.g. after updating to a new version of api.video) or was this always a problem?
* If the problem started happening recently.**
* **Can you reliably reproduce the issue?** If not, provide details about how often the problem happens and under which conditions it normally happens.
Include details about your configuration and environment:
* **Which version of the api.video package are you using?**
* **What's the name and version of the OS you're using?**
### Suggesting enhancements
This section guides you through submitting an enhancement suggestion for api.video project, including completely new features and minor improvements to existing functionality. Following these guidelines helps maintainers and the community understand your suggestion :pencil: and find related suggestions :mag_right:.
When you are creating an enhancement suggestion, please [include as many details as possible](#how-do-i-submit-a-good-enhancement-suggestion). Fill in [the template](https://github.com/apivideo/.github/blob/main/.github/ISSUE_TEMPLATE/feature_request.yml), including the steps that you imagine you would take if the feature you're requesting existed.
#### How do I submit a (good) enhancement suggestion?
Enhancement suggestions are tracked as [GitHub issues](https://guides.github.com/features/issues/). After you've determined which repository your enhancement suggestion is related to, create an issue on that repository and provide the following information:
* **Use a clear and descriptive title** for the issue to identify the suggestion.
* **Provide a step-by-step description of the suggested enhancement** in as many details as possible.
* **Provide specific examples to demonstrate the steps**. Include copy/pasteable snippets which you use in those examples, as [Markdown code blocks](https://help.github.com/articles/markdown-basics/#multiple-lines).
* **Describe the current behavior** and **explain which behavior you expected to see instead** and why.
* **Include screenshots** which help you demonstrate the steps or point out the part of api.video which the suggestion is related to.
* **Explain why this enhancement would be useful** to most api.video users and isn't something that can or should be implemented as a community package.
* **Specify which version of the api.video package you're using.**
* **Specify the name and version of the OS you're using.**
### Pull requests
The process described here has several goals:
- Maintain api.video's quality
- Fix problems that are important to users
- Engage the community in working toward the best possible api.video
- Enable a sustainable system for api.video's maintainers to review contributions
Please follow these steps to have your contribution considered by the maintainers:
1. Explain what, why and how you resolved the issue. If you have a related issue, please mention it.
2. Follow the [style guides](#style-guides)
3. After you submit your pull request, verify that all [status checks](https://help.github.com/articles/about-status-checks/) are passing <details><summary>What if the status checks are failing?</summary>If a status check is failing, and you believe that the failure is unrelated to your change, please leave a comment on the pull request explaining why you believe the failure is unrelated. A maintainer will re-run the status check for you. If we conclude that the failure was a false positive, then we will open an issue to track that problem with our status check suite.</details>
While the prerequisites above must be satisfied prior to having your pull request reviewed, the reviewer(s) may ask you to complete additional design work, tests, or other changes before your pull request can be ultimately accepted.
## Style guides
### Git commit messages
* Use the present tense ("Add feature" not "Added feature")
* Limit the first line to 72 characters or less
* Reference issues and pull requests after the first line
* Consider starting the commit message with an applicable emoji:
* :art: `:art:` when improving the format/structure of the code
* :racehorse: `:racehorse:` when improving performance
* :non-potable_water: `:non-potable_water:` when plugging memory leaks
* :memo: `:memo:` when writing docs
* :penguin: `:penguin:` when fixing something on Linux
* :apple: `:apple:` when fixing something on macOS
* :checkered_flag: `:checkered_flag:` when fixing something on Windows
* :bug: `:bug:` when fixing a bug
* :fire: `:fire:` when removing code or files
* :green_heart: `:green_heart:` when fixing the CI build
* :white_check_mark: `:white_check_mark:` when adding tests
* :lock: `:lock:` when dealing with security
* :arrow_up: `:arrow_up:` when upgrading dependencies
* :arrow_down: `:arrow_down:` when downgrading dependencies
* :shirt: `:shirt:` when removing linter warnings
### Documentation style guide
* Use [Markdown](https://daringfireball.net/projects/markdown).

# Flutter RTMP Live stream Client
[api.video](https://api.video/) is the video infrastructure for product builders. Lightning fast
video APIs for integrating, scaling, and managing on-demand & low latency live streaming features in
your app.
</documentation_only>-->
## Project description
This module is made for broadcasting RTMP live stream from smartphone camera.
## Getting started
### Installation
Run the following command at the root of your project:
```shell
flutter pub add apivideo_live_stream
```
In your dart file, import the package:
```dart
import 'package:apivideo_live_stream/apivideo_live_stream.dart';
```
### Permissions
To be able to broadcast, you must:
1. On Android: ask for internet, camera and microphone permissions:
```xml
<manifest>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.CAMERA" />
</manifest>
```
The library will require android.permission.CAMERA and android.permission.RECORD_AUDIO at runtime.
You don't need to request them.
2. On iOS: update the Info.plist with a usage description for camera and microphone
```xml
<key>NSCameraUsageDescription</key>
<string>Your own description of the purpose</string>
<key>NSMicrophoneUsageDescription</key>
<string>Your own description of the purpose</string>
```
### Code sample
1. Creates a live stream controller
```dart
final ApiVideoLiveStreamController _controller = ApiVideoLiveStreamController(
initialAudioConfig: AudioConfig(), initialVideoConfig: VideoConfig.withDefaultBitrate());
```
2. Initializes the live stream controller
```dart
await _controller.initialize();
```
3. Adds a CameraPreview widget as a child of your view
```dart
@override
Widget build(BuildContext context) {
return SizedBox(
width: 300.0,
height: 300.0,
child: ApiVideoCameraPreview(controller: _controller));
}
```
`ApiVideoCameraPreview` parameters:
- `controller`: the live stream controller
- `fit`: the fit of the preview (default is BoxFit.contain,
see [BoxFit](https://api.flutter.dev/flutter/painting/BoxFit.html) for more information)
- `child`: a child widget to overlay on top of the preview (optional)
4. Starts a live stream
```dart
_controller.startStreaming("YOUR_STREAM_KEY");
```
5. Stops streaming and preview
```dart
_controller.stop();
```
#### Manage application lifecycle
On the application side, you must manage application lifecycle:
```dart
@override
void didChangeAppLifecycleState(AppLifecycleState state) {
if (state == AppLifecycleState.inactive) {
_controller.stop();
} else if (state == AppLifecycleState.resumed) {
_controller.startPreview();
}
}
```
## Example App
You can try
our [example app](https://github.com/apivideo/api.video-flutter-live-stream/tree/master/example),
feel free to test it.
### Setup
Be sure to follow the [Flutter installation steps](https://docs.flutter.dev/get-started/) before
anything.
1) Open Android Studio
2) File > New > Project from Version Control
In URL field, type:
```shell
git@github.com:apivideo/api.video-flutter-live-stream.git
```
Wait for the indexation to finish.
#### Android
Connect an Android device to your computer and click on the `Run main.dart` button.
#### iOS
1) Connect an iOS device to your computer and click on the `Run main.dart` button.
2) The build will fail because you haven't set your development profile, sign your application:
Open Xcode, click on "Open a project or file" and open
the `YOUR_PROJECT_NAME/example/ios/Runner.xcworkspace` file.
<br />Click on Example, go in `Signin & Capabilities` tab, add your team and create a unique bundle
identifier.
