Android - 在一个圆圈中显示 ExoPlayer

Question

我试图在一个圆圈内显示一个 ExoPlayerView，覆盖另一个 ExoPlayer(画中画):

我曾尝试将第二个播放器放在圆角框架内(this answer 和 this one)，但播放器总是会脱离父框架并绘制视频的完整矩形。

我找到了 this solution它使用 GLSurfaceView，但是此解决方案使用经典的 MediaPlayer 而不是 ExoPlayer。

Answer 1

对于应该有圆角的那个，你可以在布局XML文件中这样设置:

app:surface_type="texture_view"

找到这个解决方案 here .

使用它的缺点主要是性能和电池使用(写成here):

Should I use SurfaceView or TextureView? SurfaceView has a number of benefits over TextureView for video playback:

Significantly lower power consumption on many devices. More accurate frame timing, resulting in smoother video playback. Support for secure output when playing DRM protected content. SurfaceView should therefore be preferred over TextureView where possible. TextureView should be used only if SurfaceView does not meet your needs. One example is where smooth animations or scrolling of the video surface is required prior to Android N (see How do I get smooth animation/scrolling of video?). For this case, it’s preferable to use TextureView only when SDK_INT is less than 24 (Android N) and SurfaceView otherwise.
