[Video Player] PlatformException occurs in video_player example

[makotosato-at]

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>

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)
#0      AndroidVideoPlayerApi.setMixWithOthers (package:video_player_android/src/messages.g.dart:522)
<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).

First of all, didn't you encounter build errors with flutter-elinux 3.13.0? Because event_channel API was wrong in 3.13.0 (See sony/flutter-embedded-linux@23589c3).

[makotosato-at]

Sorry. I forgot to inform.
I fixed flutter/bin/cache/artifacts/engine/elinux-common/cpp_client_wrapper/include/flutter/event_channel.h manually and then tried.

I was unable to reproduce the issue.

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

This is strange. VideoPlayer for eLinux doesn't use AndroidVideoPlayer though... Can you please try again on the top of the flutter-elinux main tree?

I tried but it did not work...
The same issue occurred on another PC(x86_64/Ubuntu 22.04 LTS).

Can you share whole logs?

flutter-elinux run -d elinux-x11 --release -vv

[makotosato-at]

I got the log.
flutter_log.txt

Hmm, it looks good. BTW, does this issue depend on flutter-elinux version?

It occurs in 3.13.0 or later.
Works fine in 3.10.6.

[HidenoriMatsubayashi]

I was able to reproduce this issue on x64 Linux host. It appears it occurs only on x64 host. It works fine on arm64 host.

[HidenoriMatsubayashi]

This issue should be resolved in #80. Can you please confirm if it's fixed in the latest plugin source files?

[makotosato-at]

Thank you.
It works fine.

One thing I noticed.
In x86 and release mode, Platform.operatingSystem returns 'android'. (3.13.0 or later)
This may be the root of this issue.
(returns 'linux' in 3.10.6)

Thanks. I filed sony/flutter-elinux#212.
