# camera_elinux
|
|
|
|
The implementation of the camera plugin for flutter elinux. APIs are designed to be API compatible with the the official [`camera`](https://github.com/flutter/plugins/tree/master/packages/camera).
|
|
|
|
## Required libraries
|
|
|
|
This plugin uses [GStreamer](https://gstreamer.freedesktop.org/) internally.
|
|
|
|
```Shell
|
|
$ sudo apt install libgstreamer1.0-dev
|
|
# Install as needed.
|
|
$ sudo apt install libgstreamer-plugins-base1.0-dev \
|
|
gstreamer1.0-plugins-base gstreamer1.0-plugins-good \
|
|
gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav
|
|
```
|
|
|
|
## Usage
|
|
|
|
### pubspec.yaml
|
|
```yaml
|
|
dependencies:
|
|
camera: ^0.10.5+3
|
|
camera_elinux:
|
|
git:
|
|
url: https://github.com/sony/flutter-elinux-plugins.git
|
|
path: packages/camera
|
|
ref: main
|
|
```
|
|
|
|
### Source code
|
|
|
|
Import `camera` in your Dart code:
|
|
```dart
|
|
import 'package:camera/camera.dart';
|
|
```
|
|
|
|
### Customization for your target devices
|
|
|
|
To improve the performance of this plugin, you will need to customize the pipeline in the source file. Please modify the source file and replace the `videoconvert` element with a H/W accelerated element of your target device to perform well.
|
|
|
|
`bool GstCamera::CreatePipeline()` in packages/camera/elinux/gst_camera.cc
|
|
|
|
#### default:
|
|
|
|
```
|
|
camerabin viewfinder-sink="videoconvert ! video/x-raw,format=RGBA ! fakesink"
|
|
```
|
|
|
|
#### i.MX 8M platforms:
|
|
|
|
```
|
|
camerabin viewfinder-sink="imxvideoconvert_g2d ! video/x-raw,format=RGBA ! fakesink"
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
If you get the following error:
|
|
```Shell
|
|
Wrong JPEG library version: library is 62, caller expects 80
|
|
```
|
|
|
|
, try the following:
|
|
```Shell
|
|
sudo mv /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstjpeg.so \
|
|
/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstjpeg.so.org
|
|
```
