About

HLS Stream Player

Features
Read full description

This app plays HLS (.m3u8) streams that are protected with HTTP Basic authentication -- the kind of stream a private or office server provides. You register the URL of your own server. The app ships with no stations and no stream list of its own. FEATURES - Register several streams and switch between them with one tap. - Works with streams that require a user name and password, over http or https. - Background playback. Audio keeps playing while you use other apps or with the screen off, and you can control it from the Lock Screen and Control Center. - The track forward and back controls on headphones and car audio switch to the next and previous stream. - Connection Test verifies the URL and the credentials before you try playback. - Import and export a settings file, so one person can configure the streams and everyone else imports them instead of typing URLs. - Automatic reconnection when the network drops, with a backoff of 1, 2, 4, 8 and 16 seconds. - Send the audio to an AirPlay speaker or a Bluetooth device from the output button on the main screen. - Give each stream its own artwork for the Lock Screen with an image URL, in the stream editor or the settings file. The app icon is used when none is set. - Streams with video show the picture on the main screen, and fill the screen when you turn the iPhone sideways. With a display connected by an HDMI cable, the picture appears on that display only. Streams without authentication can also show the picture on an Apple TV chosen from the output button; streams with authentication send only the audio. - Start and stop a stream from the Shortcuts app, from an automation such as connecting to your car over Bluetooth, or by asking Siri. Include the app name, for example "Play Office Radio with StreamPlayer". WHAT IT DOES NOT DO - In the background or with the screen locked, only the audio plays. - No offline playback and no recording. - One stream at a time. On http streams the user name and password are sent in near-plain text, so use them only on a private network. The app shows a warning when you do.
