gstreamer_video_player - issue on looping #25

@ardera I'm facing this issue on looping the video.

plugins/gstreamer_video_player/player.c: last gstreamer state change failed. gst_element_get_state(element name: pipeline0): GST_STATE_CHANGE_FAILURE
[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(nativeerror, Input/output error, 5, null)
#0      StandardMethodCodec.decodeEnvelope (package:flutter/src/services/message_codecs.dart:652:7)
#1      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:310:18)

#2      FlutterpiVideoPlayer.getPosition (package:flutterpi_gstreamer_video_player/src/platform.dart:155:20)
<asynchronous suspension>
#3      VideoPlayerController._applyPlayPause.<anonymous closure> (package:video_player/video_player.dart:582:41)
<asynchronous suspension>

Any possible solution to loop the video, the code used is from the example of the package.

Fixed rebuilding the app, strange.

I've tested for looping 10 minutes and some times still happen, how can i manage this exception? The unwanted output is that the app stop the videi and the only way is to kill and relaunch the app.

Have you found any solution? I've got the same error.

Same problem here. I'm using a pi zero2, the video loops ok then stops.

Does the player allow an array of looping videos?

ardera commented 5 months ago

Okay, I've reproduced it, it seems to be either kernel or gstreamer related. Somehow, sometimes on end of stream, the buffer sharing between kernel and gstreamer gets confused - gstreamer thinks some buffer is currently not queued/used in kernel, but some time later it dequeues that exact buffer from the kernel and emits a stream error because that shouldn't have been possible. Though no idea what causes it.

As a super hacky workaround, one could create a new video player controller in flutter at every end of stream.
