Мне хотелось бы узнать, как отправить видео с URL-адреса m3u8 из моего приложения iOS, чтобы играть на моем телевизоре через Google ChromeCast. Плейлист содержит кучу URL-адресов. Сейчас у меня есть:Google ChromeCast play m3u8 от iOS
- (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 установлен в:
<Files "wp-config.php">
Order allow,deny
Deny from all
Header set Access-Control-Allow-Origin "*"
</Files>
Когда я поток от моего IOS устройства к CHROMECAST, я вижу на телевизоре www.myURL.com/Cast/mpl .html страницы, только она заполнена с:
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
Мой mpl.html происходит от https://github.com/googlecast/CastMediaPlayerStreamingDRM, а затем я скопировать и вставить с сайта Google, например: https://google-developers.appspot.com/cast/docs/player?hl=id

Какой приемник вы используете? Что показывает журнал приемника? Установили ли вы CORS? –
Привет, Я использую пользовательский приемник. Я установил URL-адрес в cast.google.com/publish на www.myURL/Cast/mpl.html. Я установил CORS, отредактировав .htaccess, чтобы Header установил Access-Control-Allow-Origin "*". При запуске с сайта www.myURL/Cast/index.html журнал просто говорит «запускающее приложение». Я также размещен на «godaddy» на общем сервере, поэтому я не знаю, будет ли/когда изменения .htaccess вступят в силу, если/когда они перезапускают сервер Apache, по рекомендации здесь: http: // enable-cors. org/server_apache.html – user1709076
Вход в систему http://www.myURL.com/Cast/index.html просто говорит о запуске приложения. – user1709076
