I am still waiting for oganize response and hotfix version. I just know after update version of libvlc-all the PlatformException appears
this issue after the latest library update

Reacted by Mouad ZiziThanks for the suggestion @alohadance98 , but now im migrating to media_kit since it use libmpv that reduce app size too
UPDATE: there is a package flutter_vlc_player_16kb on pub.dev which already supports 16kb page size and runs smoothly, you can switch to it @FlawLessx @twix44
I tried flutter_vlc_player_16Kb but still encountered the same error. Do you have a solution yet?
Anyone have one solution on this bug ?
this is my error:

i tried flutter_vlc_player_16kb: ^7.4.7 but still same err
Reacted by Chau Tran T.M. VN.Danang and Dilber ATEŞ
This modification can solveHas anyone been able to find a solution to this problem?
Reacted by William Silva@alohadance98 @Zeus178 @CristianCruz-Almanza , flutter_vlc_player_16kb (https://pub.dev/packages/flutter_vlc_player_16kb) solve this problem but, is not stable on live stream.
@hezhipengzipp Which file should we modify on this picture ?
After locking the screen and leaving it idle for a while, calling initialize on vlc_player_controller again will result in PlatformException(channel-error, Unable to establish connection on channel: "dev.flutter.pigeon.flutter_vlc_player_platform_interface.VlcPlayerApi.create"., null, null)

Has anyone managed to solve this terrible problem?
Hi, running on the same issue as everyone.
Playing videos work in a test environment but implementing vlc player in Piwigo/piwigo-flutter-app#228 doesn't.This result in infinite loading and
[ERROR:flutter/runtime/dart_vm_initializer.cc(40)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)while trying flutter vlc 16kb will outright crash the app withE/VLC ( 9987): [0000006e60bfb440/27b0] http generic: local stream 1 error: Stream closed (0x5)Any updates on this? At the end of this month Play Store force to update all app bundles to 16KB page size but last release is almost not working.
Hi @nechtas and all. We are busy with other tasks unfortunately, so we can't get on this one right now. But I'm happy to merge any PRs that fix this issue.
same issue, switching to flutter_vlc_player_16kb fork worked for me, so fixed for now until there's time here to fix it 👍
@illia-romanenko New year, new roadmap? Do you think you will be able to solve this doring the next weeks?
check your yamal file , dev dependency is correctly set for testing packages only , if not remove it and add in dependencies section and check after clean ..for new flutter versions, fix my all packages to compile correctly, but not for video working , i still have issue in video playing , this is for missing package Error ....
I have download vlc_flutter_player 7.4.4 and run example app but the vlc throws error PlatformException in example app
