Pull Request Overview

This PR introduces throwing behavior for unsupported codecs by validating codec formats in SRTStream and updating related APIs and call sites to handle errors.

• Added supportedAudioCodecs and supportedVideoCodecs in SRTStream, and made setAudioSettings throw unsupportedCodec for invalid formats.
• Updated HKStream protocol and its implementations (SRTStream, RTMPStream) so that setAudioSettings and setVideoSettings are throws.
• Changed all codec-setting calls to use try? await and updated example imports accordingly.

• The variable name mamimumVideoBitRate appears to be misspelled; consider renaming it to maximumVideoBitRate for clarity.

                let incremental = mamimumVideoBitRate / 10

The method setVideoSettings is now throwable but doesn’t validate supportedVideoCodecs or throw for unsupported formats. Consider adding a guard for Self.supportedVideoCodecs.contains(videoSettings.format) and throwing Error.unsupportedCodec when the codec is not supported.

Suggested change

	public func setVideoSettings(_ videoSettings: VideoCodecSettings) throws {
	public func setVideoSettings(_ videoSettings: VideoCodecSettings) throws {
	guard Self.supportedVideoCodecs.contains(videoSettings.format) else {
	throw Error.unsupportedCodec
	}

[nitpick] This throwing method currently doesn’t throw under any condition. Either implement validation for unsupported codecs to throw an error, or remove the throws declaration to avoid confusion.

Suggested change

	public func setAudioSettings(_ audioSettings: AudioCodecSettings) throws {
	public func setAudioSettings(_ audioSettings: AudioCodecSettings) {
