如何将已编码的hls v4 / v5流式传输到Chromecast？

Question

我在将视频网址投射到Chromecast时遇到了问题

我无法播放此视频

http://cdnlb.tvplayhome.lt/vod/eds/220830_test1/220830_test1/_/hls_v4/220830_test1.m3u8

但是如果我切换到hls_v3或2或1，它将在播放

http://cdnlb.tvplayhome.lt/vod/eds/220830_test1/220830_test1/_/hls_v3/220830_test1.m3u8

这是基本的实现方式

            let url = URL.init(string: "http://cdnlb.tvplayhome.lt/vod/eds/220830_test1/220830_test1/_/hls_v4/220830_test1.m3u8")
        guard let mediaURL = url else {
            print("invalid mediaURL")
            return
        }

        let mediaInfoBuilder = GCKMediaInformationBuilder.init(contentURL: mediaURL)
        mediaInfoBuilder.streamType = GCKMediaStreamType.none;
        mediaInfoBuilder.contentType = "application/x-mpegURL"
        mediaInfoBuilder.metadata = metadata
        mediaInfoBuilder.mediaTracks = nil
        let mediaInformation = mediaInfoBuilder.build()

        let rmc = GCKCastContext.sharedInstance().sessionManager.currentCastSession?.remoteMediaClient


        let request = rmc?.loadMedia(mediaInformation)
        request!.delegate = self

我正在控制台中找到它
