…TIDAL group="main" manifests TIDAL appears to have changed the MPEG-DASH MPD manifests returned for some streams to include non-numeric values in `<AdaptationSet group="...">` (e.g. group="main"). The current `mpegdash` parser expects group to be an integer and raises a `ValueError`, which `tidalapi` wraps as `ManifestDecodeError`. This caused `mopidy-tidal` playback to fail and tracks to be marked “not playable”. This PR updates mopidy-tidal’s playback provider to avoid parsing MPD manifests via tidalapi/mpegdash. For MPD manifests we only need to persist the MPD XML and return a `file://` URI, so parsing is unnecessary. **Root cause** - [`tidalapi.StreamManifest`](https://github.com/EbbLabs/python-tidal/blob/08742362ee8cef7df1362387cef60c2846aa84ee/tidalapi/media.py#L644) → [`DashInfo.from_mpd()`](https://github.com/EbbLabs/python-tidal/blob/08742362ee8cef7df1362387cef60c2846aa84ee/tidalapi/media.py#L770) → `mpegdash` parser - New MPD contains: `<AdaptationSet ... group="main" ...>` - [`mpegdash` tries to parse group as int](https://github.com/sangwonl/python-mpegdash/blob/48b52122cdbcaebe1804b79f77d05dfc1ce32900/mpegdash/nodes.py#L782) → `ValueError` → `tidalapi.exceptions.ManifestDecodeError` - Mopidy logs: backend exception + _Track is not playable_ **Changes** - **MPD path** (`ManifestMimeType.MPD`) - Stop calling `stream.get_stream_manifest()` (this triggers MPD parsing and the crash) - Use `stream.get_manifest_data()` to fetch raw MPD XML - Write the MPD to `manifest.mpd` in the extension cache directory - Return `file://…/manifest.mpd` for playback (same end result as before, but without parsing) - **BTS path** (ManifestMimeType.BTS) - Keep existing behavior using stream.get_stream_manifest() **Why this is safe** mopidy-tidal already ultimately plays MPD by writing it to disk and handing Mopidy a `file://` URI. The parsed MPD data from tidalapi wasn’t required for playback logic here; it was effectively only used for logging (codecs). Closes: EbbLabs/python-tidal#397
