本地服务器 (iOS) 上的特定视频运行滞后

Question

基于example project from google build simple player app for play video on device. Added GCDWebServer lib for local streaming. All works fine, except 1 video。它有点滞后。此视频在 AppStore 的其他播放器上播放完美。

在此处编写我如何设置 GCKCastContext 并开始在 Chromecast 上播放的代码：

static func setup() {
    let options = GCKCastOptions(discoveryCriteria: GCKDiscoveryCriteria(applicationID: kReceiverAppID))
    options.physicalVolumeButtonsWillControlDeviceVolume = true
    GCKCastContext.setSharedInstanceWith(options)


    let logFilter = GCKLoggerFilter()
    logFilter.minimumLevel = .error
    GCKLogger.sharedInstance().filter = logFilter
    GCKLogger.sharedInstance().delegate = shared

    shared.sessionManager.add(shared)
}

func generateMediaInfo(url: URL) -> GCKMediaInformation {
    let builder = GCKMediaInformationBuilder(contentURL: url)

    builder.streamType = .live
    if url.isFileURL, let mimeType = mimeTypes[url.pathExtension] {
        builder.contentType = mimeType
    }
    builder.metadata = GCKMediaMetadata(metadataType: .movie)
    builder.mediaTracks = nil
    builder.textTrackStyle = buildTextStyle()

    let mediaInfo = builder.build()
    return mediaInfo
}

func buildTextStyle() -> GCKMediaTextTrackStyle {
    let style = GCKMediaTextTrackStyle.createDefault()
    style.windowType = .roundedCorners
    style.windowColor = GCKColor(red: 0, green: 0, blue: 0, alpha: 0.7)
    return style
}

func playURL(_ url: URL, position: Double = 0) {
    let options = GCKMediaLoadOptions()
    options.playPosition = position

    let url = ChromecastServer.startServer(url.path) // builded with GCDWebServer, returns local server url
    let mediaInfo = generateMediaInfo(url: url!)

    if let client = sessionManager.currentCastSession?.remoteMediaClient {
        performAsyncIn(.main) {
            client.loadMedia(mediaInfo, with: options)
        }
    }
}

Answer 1

这是因为我没有正确响应 Content-Range 请求。固定版本：

server = GCDWebServer()
server?.addHandler(forMethod: "GET", path: "/chromecast_video", request: GCDWebServerRequest.self, processBlock: { (req) -> GCDWebServerResponse? in
    var resp: GCDWebServerFileResponse? = GCDWebServerFileResponse()
    if (req.hasByteRange()) {
        return GCDWebServerFileResponse(file: filePath, byteRange: req.byteRange)
    } else {
        return GCDWebServerFileResponse(file: filePath)
    }
})
