CicadaPlayer开始定位的是一个网络播放器，这种需求目前还没有做，没有尝试过，可能切换不了，如果要加的话，应该也比较简单，可以复用多码率hls切语言的接口，可以提供一个sample流吗？

可以用这条命令生成 ffmpeg -i input1.mp4 -i input2.aac -i input3.aac -map 0 -map 1 -map 2 -shortest output.mp4 CicadaPlayer hls多码率切换时selectTrack，实际的track是子m3u8（可能有多音轨）。 如果上层还需要切换音轨的话，是不是需要实现另一个selectTrack接口？

应该不用，复用现在的selectTrack应该就可以
