java - 如何修复 ExoPlayer 视频卡住 2.9.6

Question

我使用此代码来播放全屏视频，但是当视频播放并从主要 Activity 移动到全屏 Activity 时出现问题，视频卡住 2-3 秒 仅出现此问题仅适用于 2.8.3 之后的版本，但适用于 2.8.0 视频很流畅

Answer 1

只需尝试此代码即可解决视频卡住问题:

@Override
public void play() {
    player.setPlayWhenReady(true);
    player.getPlaybackState();
}

@Override
public void pause() {
    player.setPlayWhenReady(false);
    player.getPlaybackState();
}

这里 player.getPlaybackState(); 可以帮助完全恢复状态。
