SchemeUnsupported
data class SchemeUnsupported(val uri: String, val scheme: String, val detail: String? = null) : PlaybackError
The item's address has a scheme this build has no way to open, such as srt:// or rtmps://, or rtsp:// on the web, where the player has no sockets of its own. Nothing was sent over any network: the address was refused for its scheme alone.
The same address fails the same way every time in this build, which is what separates it from SourceUnavailable, where the bytes could not be reached this time. scheme is the address's scheme in lower case, without its colon, and detail may say what would open it. MediaItem's documentation lists the schemes each platform opens.
