android - 如何使用 Exoplayer 播放输入流？

Question

我使用以下 FrameWorkSampleSource 构造函数来初始化 SampleSource 实例。

File file = new File(path);
FileInputStream inputStream = new FileInputStream(file);
FileDescriptor fd = inputStream.getFD();
SampleSource sampleSource = new FrameworkSampleSource(fd, 0, file.length());

但我需要使用 ExoPlayer 播放 InputStream。我找不到任何实现 SampleSource 类并在其构造函数中将 InputStream 作为参数的接口(interface)。

似乎没有简单的方法可以实现这一点，因为 ExoPlayer 不是为此设计的。引用开发者的话:

"We do not provide an implementation that wraps an InputStream directly because the InputStream interface doesn't provide suitable random access behavior for media playback, which is required both for seeking and because some media formats place data at the end of the file that must be read at the start of playback."
