The video player `value.isBuffering` always return true after `seekTo` any position #165149

PachecoLpG · 2025-03-13T19:54:43Z

Steps to reproduce

Start the video and seekTo any position

Expected results

isBuffering should return false after buffering

Actual results

isBuffering remains true for the entire duration of the video and the video continues to play

Code sample

import 'package:flutter/material.dart';
import 'package:video_player/video_player.dart';

void main() => runApp(const VideoApp());

/// Stateful widget to fetch and then display video content.
class VideoApp extends StatefulWidget {
  const VideoApp({super.key});

  @override
  _VideoAppState createState() => _VideoAppState();
}

class _VideoAppState extends State<VideoApp> {
  late VideoPlayerController _controller;
  

  @override
  void initState() {
    super.initState();
    _controller = VideoPlayerController.networkUrl(Uri.parse(
        "https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ElephantsDream.mp4"))
      ..initialize().then((_) {
        // Ensure the first frame is shown after the video is initialized, even before the play button has been pressed.
        setState(() {});
      });

    _controller.addListener(printBuffer);
  }

  void printBuffer() => print(_controller.value.isBuffering);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Video Demo',
      home: Scaffold(

                });
              },

Reproducible using the code sample provided above. This appears to work fine on iOS but not on android. See the recordings below

Notice that on android, once the skip button is tapped, the buffering never stops.

Tested with video_player: ^2.9.3

We recently had to disable a test in flutter/packages CI because of this; the test was waiting for buffering to report stopped, and never was. This was an out-of-band failure whose cause we were not able to determine. Our only guess was that this changed in ExoPlayer, but we couldn't see any obvious reason that the ExoPlayer version would have changed out of band (since Gradle deps don't automatically pull the latest, unlike unpinned pub deps).

wenwangwill · 2025-04-01T03:20:33Z

If you want to temporarily solve this problem, you can compare the current playback position with the buffer position to determine whether it is in the buffer.

      controller.addListener(() {
        final value = controller.value;
        final buffer = value.buffered.lastOrNull?.end.inMilliseconds;
        final position = value.position.inMilliseconds;
        bool buffering = position == buffer;
      });

timoxd7 · 2025-04-02T10:56:26Z

@wenwangwill Thanks for the workaround. This indeed works, however if seekTo a previous position while having the video paused, this might give a true on buffering even though it is not buffering nor playing. But as workaround for now, this seems good.

xshiwei · 2025-04-02T12:45:31Z

I still hope it can be solved as soon as possible, this problem is quite serious

AnalabaSylvester · 2025-04-02T20:23:15Z

this is a realy serious issues, and really feels worse on live stream where you wont want to track seek position .

AnalabaSylvester · 2025-04-02T20:25:26Z

void _updateState() {
if (mounted) {
final newIsPlaying = widget.controller.value.isPlaying;
final newPosition = widget.controller.value.position.inSeconds.toDouble();
final position = widget.controller.value.position;
final buffered = widget.controller.value.buffered;

  // Custom buffering logic: Check if position is outside all buffered ranges
  final newIsBuffering =
      buffered.isEmpty ||
      !buffered.any(
        (range) => position >= range.start && position <= range.end,
      );

  if (_isPlaying != newIsPlaying ||
      _currentPosition != newPosition ||
      _isBuffering != newIsBuffering) {
    setState(() {
      _isPlaying = newIsPlaying;
      _currentPosition = newPosition;
      _isBuffering = newIsBuffering;
      if (_isBuffering && _isVisible) {
        _isVisible = false; // Hide controls if buffering starts
        _hideTimer?.cancel(); // Cancel hide timer if active
      }
    });
  }

  // Debug logging
  log(
    "Position: $position, Buffered: ${buffered.map((r) => '[${r.start}-${r.end}]').join(', ')}",
  );
  log(
    "Custom Buffering: $_isBuffering, Official: ${widget.controller.value.isBuffering}",
  );
}

} . this walk around helps a little tho but did not fully meet my requirement .

Limit video_player_android to version 2.7.17, do not upgrade!

neo-etremblay · 2025-04-23T19:23:56Z

I also have this issue with video_player_android 2.8.2

iammofidul · 2025-04-24T10:27:17Z

bool isActuallyBuffering = controller.value.isBuffering; if (controller.value.isPlaying && controller.value.position.inMilliseconds > 0 && controller.value.isBuffering) { isActuallyBuffering = false; }

Until they fixed it we can use above workaround
