v1.9.1

[TiTidom-RC]

This pull request adds support for multiple audio file formats (mp3, wav, ogg, opus, flac) throughout the TTS Cast plugin, improving flexibility for users uploading and playing custom sounds. It also updates the backend and proxy logic to safely handle these new file types, and modifies the Python daemon to use a proxy endpoint for serving audio files with correct MIME types.

Audio Format Support and Validation:

• Expanded allowed upload formats for custom sounds to include .wav, .ogg, .opus, and .flac in addition to .mp3, and updated validation and error messages accordingly in ttscast.ajax.php and the plugin configuration UI. [1] [2]
• Updated getSoundList() and getCustomSoundList() to list all supported audio file types, not just .mp3. [1] [2]

File Handling and Security:

• Ensured file uploads and downloads use safe filenames (via basename) to prevent directory traversal, and updated the proxy script (ttscast.audio.proxy.php) to validate file names and extensions for all supported formats and request types. [1] [2]

Proxy and Daemon Integration:

• Modified the Python daemon (ttscastd.py) to use a new proxy endpoint (ttsWebSrvMediaProxy) for serving both standard and custom sounds, passing the filename and type as query parameters and encoding filenames safely. [1] [2] [3]
• Dynamically set the correct MIME type for each audio file based on its extension when casting, ensuring compatibility with various devices.

Miscellaneous:

• Bumped plugin version to 1.9.1 in info.json.
• Minor import fix in ttscastd.py for quote from urllib.parse.
