Please tell me, what may be the cause， thanks

Anyone had luck integrating media-kit with elinux for video playback?
media-kit uses libmpv under the hood on Linux.

hi, i run video/sample on pi,

Sorry to bother you again, I couldn't compile when integrating the video playback function. Here are some instructions for my project:

1. Add dependencies:
   video_player: ^2.8.2
   video_player_elinux:
   git:
   url: https://github.com/sony/flutter-elinux-plugins.git
   path: packages/video_player
   Ref: main
2. Before adding dependencies, I can compile the product normally and execute it on the embedded device. The command used is: flutter-elinux build elinux --target-backend-type=x11 --target-arch=arm64, and I am in Added set(CMAKE_CXX_COMPILER aarch64-linux-gnu-g++-10) to elinux/CmakeLists.txt.
3. I have asked similar questions before(#93 ), but I am a newbie, what should I do?too difficult.

Hello.

I have an iMX8M Mini. I tried the example/demo application as is. However, I seem to have 2 issues:

1. An error happen when pressing play [ERROR:/usr/src/debug/flutter-auto-runtimerelease/git-r0/git/shell/static_plugins/gstreamer_egl/gstreamer_egl.cc(1552)] Unable to retrieve current position.
2. The metadata appears but nothing happens. If I use the following pipeline I can stream videos with gstreamer though: $ gst-launch-1.0 filesrc location=/path/to/video.mp4 ! qtdemux ! queue ! h264parse ! v4l2h264dec ! imxvideoconvert_g2d ! queue ! autovideosink.

Here is a log of what happens:

Add gamepad plugin

i run main.dart, always "Button tapped 1 time", when i restart App, it become "0 times".I just added some printing:

Future _incrementCounter() async {
final Map<String, Object> values = await prefs.getAll();
final int counter = (values['counter'] as int? ?? 0) + 1;
print('_incrementCounter:values:$values');
setState(() {
_counter = prefs.setValue('Int', 'counter', counter).then((bool success) {
print('_incrementCounter:success:$success');
return counter;
});
});
}

No matter how many times i click，output always:
_incrementCounter:values:{}
_incrementCounter:success:true
...

No error message is reported。
so，where might the problem occur?
Looking forward to your reply,
thanks.

hello，When I directly run main.dart, I receive the following error：

It seems to be a compatibility issue. How can I solve this problem? Thank you.

Hello.
I have i.MX8MP board and using video_player.
This SoC has a VPU(Video Proccessing Unit) so that it can hardware decode H.264 with gstreamer.
But, 1080p 30fps or 60fps video, the following gst_buffer_extract() is the bottleneck and playback is slow.
(gst_extract_buffer() takes about 60ms.)
gst_video_player.cc:

const uint8_t* GstVideoPlayer::GetFrameBuffer() {
  std::shared_lock<std::shared_mutex> lock(mutex_buffer_);
  if (!gst_.buffer) {
    return nullptr;
  }

  const uint32_t pixel_bytes = width_ * height_ * 4;
  gst_buffer_extract(gst_.buffer, 0, pixels_.get(), pixel_bytes);
  return reinterpret_cast<const uint8_t*>(pixels_.get());
}

I think the availability of dmabuf would solve this problem.
Are there any plans to support gstreamer dmabuf in video_player?
(In my environment, gst_is_dmabuf_memory() returns TRUE, so I can use dmabuf.)

Hi,

I'm trying to use the video-player plugin in flutter-elinux-plugins.
When running the example on the my ubuntu desktop, it completely works ok.

But when I cross compile this and run video-player-plugin example on an arm64 embedded linux environment
I encountered the error below during initialization.

Do I need a video player inside my embedded linux environment to be able to run this?
I'm running this over weston using flutter-client.

$> flutter-client --bundle=pathOfBundle -f

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)

#1 VideoPlayerController.initialize (package:video_player/video_player.dart:434)

I copied the same code: https://github.com/sony/flutter-elinux-plugins/blob/main/packages/video_player/example/lib/main.dart

but it crash

Is it possible to write plugins in languages other than C? For example Python, Go etc?

Create AudioPlayer plugin

Hello.

I have a question about the return value of GstVideoPlayer::HandleGstMessage().

Why does GstVideoPlayer::HandleGstMessage() return GST_BUS_PASS as in the following code?
https://github.com/sony/flutter-elinux-plugins/blob/main/packages/video_player/elinux/gst_video_player.cc#L475

I think it should return GST_BUS_DROP.

Create Shared preference plugin

Hello.

I'm using Debian(bullseye) on my PC(x86_64) and flutter-elinux 3.13.0
When I run the video_player example, I get the following error:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)
#0      AndroidVideoPlayerApi.initialize (package:video_player_android/src/messages.g.dart:272)

<asynchronous suspension>
#1      VideoPlayerController.initialize (package:video_player/video_player.dart:361)
<asynchronous suspension>

Here are the steps:

$ git clone https://github.com/sony/flutter-elinux-plugins.git
$ cd flutter-elinux-plugins/packages/video_player/example
$ flutter-elinux pub get
$ flutter-elinux run -d elinux-x11 --release

It does not occur in debug mode(--debug).

Hi

I am trying to use the camera plugins on the following configuration

1. amd64 Ubuntu 22.04 linux
2. flutter-elinux: 3.13.2
3. camera: 0.10.5+5
4. camera_elinux: https://github.com/sony/flutter-elinux-plugins.git (main branch)
5. Display: X11

When I invoke the camera controller startVideoCapturing, I get the following exception

MissingPluginException(No implementation found for method startVideoRecording on channel plugins.flutter.io/camera)

Thanks

Create Path provider plugin

copied the same code: https://github.com/sony/flutter-elinux-plugins/blob/main/packages/video_player/example/lib/main.dart in flutter project.

Currently when playing videos higher than 1080p 30fps(for example 1080p 60fps) it cause player to lose sound and play slower(1080p 60 fps plays like 30), the higher resolution - slower playback is.

• On 4K it looks like slow motion video.
• HW acceleration is present ( VAAPI ), also tried separate pipeline without sound, just video - same result. Pipeline: filesrc ! qtdemux ! queue ! h264parse ! vaapih264dec ! vaapipostproc ! fakesink
• When sound disappears underflow happens: WARN pulse pulsesink.c:703:gst_pulsering_stream_underflow_cb:<audiosink-actual-sink-pulse> Got underflow
• There's no resources starvation CPU/GPU

Tests were performed with big-buck samples:

• 1080p 30fps(no issues)
• 1080p 60 fps(video playback looks like 30 fps or slower, sound disappears once introduction animation ends)
• 4K 30 fps (super slow video, same issue with sound )

Tested on Laptop with Ubuntu 20.04, Intel HD Graphics ( Latest drivers as well as VAAPI lib were built from source )
Playback is fine in separate window if don't provide videosink to playbin.

hi,
What are the solutions for video on other platforms? For example, Raspberry Pi

Create URL launcher plugin, but I have no ideas now.

Create WebRTC plugin
https://github.com/flutter-webrtc/flutter-webrtc

Currently, auto-repeat (looping video) doesn't work correctly.
