camera_desktop

+ +

+Platform +Language: Dart +
+Pub Version +pub points +Flutter CI +License +

+ +A Flutter camera plugin for desktop platforms. Implements +[`camera_platform_interface`](https://pub.dev/packages/camera_platform_interface) +so it works seamlessly with the standard +[`camera`](https://pub.dev/packages/camera) package and `CameraController`. + +## Platform Support + +| Platform | Backend | Status | +|----------|---------|--------| +| **Linux** | GStreamer + V4L2 | Included | +| **macOS** | AVFoundation | Included | +| **Windows** | Media Foundation | Included | + +## Installation + +Add `camera_desktop` alongside `camera` in your `pubspec.yaml`: + +```yaml +dependencies: + camera: ^0.11.0 + camera_desktop: ^1.2.1 +``` + +That's it. All three desktop platforms are covered, no additional packages needed. + +## Usage + +Use the standard `camera` package API: + +```dart +import 'package:camera/camera.dart'; + +final cameras = await availableCameras(); +final controller = CameraController(cameras.first, ResolutionPreset.high); +await controller.initialize(); + +// Preview +CameraPreview(controller); + +// Capture +final file = await controller.takePicture(); + +// Record +await controller.startVideoRecording(); +final video = await controller.stopVideoRecording(); +``` + +### Advanced Settings + +`CameraController` (camera 0.11.x+) accepts optional `fps`, `videoBitrate`, and +`audioBitrate` parameters at construction time: + +```dart +final controller = CameraController( + cameras.first, + ResolutionPreset.veryHigh, + enableAudio: true, + fps: 30, + videoBitrate: 5000000, // 5 Mbps + audioBitrate: 128000, // 128 kbps +); +``` + +These settings are applied during `initialize()`. To change them you must +`dispose()` the controller and create a new one, see [Limitations](#limitations). + +## Platform-Specific Setup + +### Linux + +Install GStreamer development libraries: + +```bash +# Ubuntu/Debian +sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev gstreamer1.0-plugins-good + +# Fedora +sudo dnf install gstreamer1-devel gstreamer1-plugins-base-devel gstreamer1-plugins-good + +# Arch +sudo pacman -S gstreamer gst-plugins-base gst-plugins-good +``` + +### macOS + +Add camera and microphone usage descriptions to your `Info.plist`: + +```xml +NSCameraUsageDescription +This app needs camera access. +NSMicrophoneUsageDescription +This app needs microphone access for video recording. +``` + +For sandboxed apps, add to your entitlements: + +```xml +com.apple.security.device.camera + +com.apple.security.device.audio-input + +``` + +### Windows + +No additional setup required. + +## Features + +| Feature | Linux | macOS | Windows | +|---------|-------|-------|---------| +| Camera enumeration | Yes | Yes | Yes | +| Live preview | Yes | Yes | Yes | +| Photo capture | Yes | Yes | Yes | +| Video recording | Yes | Yes | Yes | +| Image streaming | Yes | Yes | Yes | +| Audio recording | Yes | Yes | Yes | +| Resolution presets | Yes | Yes | Yes | +| Custom FPS | Yes | Yes | Yes | +| Video bitrate control | Yes | Yes | Yes | +| Audio bitrate control | Yes | Yes | Yes | +| Mirror control | Yes | Yes | No (handled in Flutter) | + +## Mirror / Flip Behavior + +On **macOS** and **Linux**, the preview frames are mirrored at the native capture +level (like a webcam selfie view), so `buildPreview()` returns the texture as-is. +The mirror state can be toggled at runtime via `setMirror()`: + +```dart +import 'package:camera_desktop/camera_desktop.dart'; + +// Toggle mirror at runtime (macOS & Linux only) +final plugin = CameraDesktopPlugin(); +await plugin.setMirror(cameraId, false); // disable mirror +await plugin.setMirror(cameraId, true); // re-enable mirror +``` + +On **Windows**, the native backend does not mirror, so the example app wraps the +preview in a horizontal `Transform` in Flutter: + +```dart +if (Platform.isWindows) { + return Transform( + alignment: Alignment.center, + transform: Matrix4.diagonal3Values(-1, 1, 1), + child: Texture(textureId: textureId), + ); +} +``` + +The same applies to video playback. Recorded files from macOS/Linux are already +mirrored, while Windows recordings need a Flutter-side flip if you want a +mirror-style playback. + +## Platform Capabilities + +Query what the current platform supports at runtime: + +```dart +import 'package:camera_desktop/camera_desktop.dart'; + +final caps = await CameraDesktopPlugin().getPlatformCapabilities(); +// caps['supportsMirrorControl'] == true (macOS & Linux) +// caps['supportsVideoFpsControl'] == true +// caps['supportsVideoBitrateControl'] == true +// caps['supportsAudioBitrateControl'] == true +``` + +This is useful when building UIs that conditionally expose controls based on the +running platform. + +## Limitations + +Desktop cameras generally do not support mobile-oriented features: + +- Flash/torch control +- Exposure/focus point selection +- Zoom (beyond 1.0x) +- Device orientation changes +- Pause/resume video recording + +These methods either no-op or throw `CameraException` as appropriate. + +`fps`, `videoBitrate`, and `audioBitrate` are applied at initialization and cannot +be changed on a running controller. To update them, `dispose()` the controller and +create a new one with the desired settings. diff --git a/plugins/camera_desktop/analysis_options.yaml b/plugins/camera_desktop/analysis_options.yaml new file mode 100644 index 0000000..a5744c1 --- /dev/null +++ b/plugins/camera_desktop/analysis_options.yaml @@ -0,0 +1,4 @@ +include: package:flutter_lints/flutter.yaml + +# Additional information about this file can be found at +# https://dart.dev/guides/language/analysis-options diff --git a/plugins/camera_desktop/android/build.gradle b/plugins/camera_desktop/android/build.gradle new file mode 100644 index 0000000..77b64a2 --- /dev/null +++ b/plugins/camera_desktop/android/build.gradle @@ -0,0 +1,48 @@ +group = "com.hugocornellier.camera_desktop" +version = "1.0-SNAPSHOT" + +buildscript { + ext.kotlin_version = "2.1.0" + repositories { + google() + mavenCentral() + } + + dependencies { + classpath("com.android.tools.build:gradle:8.9.1") + classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version") + } +} + +allprojects { + repositories { + google() + mavenCentral() + } +} + +apply plugin: "com.android.library" +apply plugin: "kotlin-android" + +android { + namespace = "com.hugocornellier.camera_desktop" + + compileSdk = 36 + + compileOptions { + sourceCompatibility = JavaVersion.VERSION_11 + targetCompatibility = JavaVersion.VERSION_11 + } + + kotlinOptions { + jvmTarget = JavaVersion.VERSION_11 + } + + sourceSets { + main.java.srcDirs += "src/main/kotlin" + } + + defaultConfig { + minSdk = 24 + } +} diff --git a/plugins/camera_desktop/android/src/main/AndroidManifest.xml b/plugins/camera_desktop/android/src/main/AndroidManifest.xml new file mode 100644 index 0000000..dba8dcb --- /dev/null +++ b/plugins/camera_desktop/android/src/main/AndroidManifest.xml @@ -0,0 +1,3 @@ + + diff --git a/plugins/camera_desktop/android/src/main/kotlin/com/hugocornellier/camera_desktop/CameraDesktopPlugin.kt b/plugins/camera_desktop/android/src/main/kotlin/com/hugocornellier/camera_desktop/CameraDesktopPlugin.kt new file mode 100644 index 0000000..c4db6c5 --- /dev/null +++ b/plugins/camera_desktop/android/src/main/kotlin/com/hugocornellier/camera_desktop/CameraDesktopPlugin.kt @@ -0,0 +1,34 @@ +package com.hugocornellier.camera_desktop + +import io.flutter.embedding.engine.plugins.FlutterPlugin +import io.flutter.plugin.common.MethodCall +import io.flutter.plugin.common.MethodChannel +import io.flutter.plugin.common.MethodChannel.MethodCallHandler +import io.flutter.plugin.common.MethodChannel.Result + +/** CameraDesktopPlugin */ +class CameraDesktopPlugin : + FlutterPlugin, + MethodCallHandler { + private lateinit var channel: MethodChannel + + override fun onAttachedToEngine(flutterPluginBinding: FlutterPlugin.FlutterPluginBinding) { + channel = MethodChannel(flutterPluginBinding.binaryMessenger, "camera_desktop") + channel.setMethodCallHandler(this) + } + + override fun onMethodCall( + call: MethodCall, + result: Result + ) { + if (call.method == "getPlatformVersion") { + result.success("Android ${android.os.Build.VERSION.RELEASE}") + } else { + result.notImplemented() + } + } + + override fun onDetachedFromEngine(binding: FlutterPlugin.FlutterPluginBinding) { + channel.setMethodCallHandler(null) + } +} diff --git a/plugins/camera_desktop/ci/check_unicode_inventory.py b/plugins/camera_desktop/ci/check_unicode_inventory.py new file mode 100755 index 0000000..cb1b748 --- /dev/null +++ b/plugins/camera_desktop/ci/check_unicode_inventory.py @@ -0,0 +1,74 @@ +#!/usr/bin/env python3 +"""Assert that every non-ASCII character appearing in windows/*.cpp|*.h also +appears in ci/cp936_repro.cpp. + +Purpose: the CP936 simulation step in CI compiles cp936_repro.cpp to prove that +/utf-8 resolves C4819 for the exact character set we use.
