我正试图让fmp4 HLS在新的Chromecast上播放(我相信是第三代，而不是Ultra(。
我已经尝试过使用x264和h264库使用ffmpeg对内容进行编码。主配置文件最初给了我一个不支持编解码器的错误，从hls清单中删除编解码器列表修复了这个问题。
切换到基线(这并不理想(不会导致编解码器错误。
然后两者(在删除编解码器定义或使用基线后(都会给出以下错误：
Uncaught Error: Unable to derive timescale

确保您没有设置：
loadRequestData.media.hlsSegmentFormat

loadRequestData.media.hlsSegmentFormat = cast.framework.messages.HlsSegmentFormat.TS;
但对于fmp4，我对此进行了评论。
