我想知道如何从我的 iOS 应用程序发送来自 m3u8 URL 的视频，以便通过 Google ChromeCast 在我的电视上播放。播放列表包含一堆“ts”网址。现在我有:
- (void)deviceManager:(GCKDeviceManager *)deviceManager
didConnectToCastApplication:(GCKApplicationMetadata *)applicationMetadata
sessionID:(NSString *)sessionID
launchedApplication:(BOOL)launchedApp
{
_gcChannel = [[GCKMediaControlChannel alloc] init];
_gcChannel.delegate = self;
[deviceManager addChannel: _gcChannel];
GCKMediaMetadata *metadata = [[GCKMediaMetadata alloc] init];
NSTimeInterval startTime = 0;
[metadata setString:@"Stream it" forKey:kGCKMetadataKeyTitle];
GCKMediaInformation *mediaInformation = [[GCKMediaInformation alloc] initWithContentID:URLTOM3U8 streamType:GCKMediaStreamTypeUnknown contentType:@"video/m3u8" metadata:metadata streamDuration:0 customData:nil];
[_gcChannel loadMedia:mediaInformation autoplay:YES playPosition:startTime];
.htaccess 设置为:
<Files "wp-config.php">
Order allow,deny
Deny from all
Header set Access-Control-Allow-Origin "*"
</Files>
当我从我的 iOS 设备流式传输到 chromeCast 时，我在电视上看到 www.myURL.com/Cast/mpl.html 页面，只有它填写了:
Media Player State: 'underflow true'
Media Host State 'fatal error code = 3'
Media Protocol ' HLS'
.....
License Server URL:
Manifest Credentials: false
Segment Credentials: false
License Credentials: false
我的 mpl.html 来自 https://github.com/googlecast/CastMediaPlayerStreamingDRM然后我从谷歌的网站示例中复制并粘贴:https://google-developers.appspot.com/cast/docs/player?hl=id

最佳答案
将 streamType 设置为 GCKMediaStreamTypeNone 并将 contentType 设置为 "video/m3u" 对我来说使用符合 HLS 的 AVC/AAC 流默认接收者:
GCKMediaInformation *mediaInformation =
[[GCKMediaInformation alloc] initWithContentID:
@"https://example.com/path/to/playlist.m3u8"
streamType:GCKMediaStreamTypeNone
contentType:@"video/m3u"
metadata:metadata
streamDuration:0
customData:nil];
关于ios - Google ChromeCast 从 iOS 播放 m3u8，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24431940/
