better_player在颤振中添加video_trimmer后停止工作
提问于 2022-09-02 20:24:38
Better_Player在添加Video_Trimmer之前就开始工作了，但是在我添加了Video_Trimmer之后，它停止了播放视频，如果我再次删除Video_Trimmer，Better_Player就会工作。
我测试过的东西：
- 卸载和重新安装应用程序
- 使用较低版本的Better_Player
better_player: ^0.0.83
video_trimmer: ^1.1.3控制台错误是：

我面临着同样的问题，现在通过遵循这个#1085解决了这个问题
要解决这个问题，只需使用以下better_player版本：
替换
better_player: ^0.0.83通过
better_player:
git:
url: https://github.com/tintran-dev/betterplayer.git还要确保已经为m3u8和mdp添加了m3u8。
BetterPlayerDataSource dataSource = BetterPlayerDataSource(
BetterPlayerDataSourceType.network,
"url",
videoFormat: BetterPlayerVideoFormat.hls,
drmConfiguration: BetterPlayerDrmConfiguration(
drmType: BetterPlayerDrmType.token,
token: "Bearer=token",
),
