ffmpeg - Chromecast HLS : Unable to derive timescale

Question

我正在尝试让 fmp4 HLS 在新的 Chromecast(我相信第三代，而不是 Ultra)上播放。
我尝试使用 x264 和 h264 库使用 ffmpeg 对内容进行编码。
主要配置文件最初给了我一个编解码器不支持的错误，从 hls list 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)不会产生编解码器错误。
然后(在删除编解码器定义或使用基线之后)都给出以下错误:

Uncaught Error: Unable to derive timescale

Answer 1

确保您没有设置:

loadRequestData.media.hlsSegmentFormat

对于 TS，我必须设置:

loadRequestData.media.hlsSegmentFormat = cast.framework.messages.HlsSegmentFormat.TS;

但是对于 fmp4，我将其注释掉了。
