* fix(transcoding): don't apply server-side transcoding override on getTranscodeDecision The getTranscodeDecision endpoint was incorrectly applying server-side player transcoding overrides (forced format and MaxBitRate cap), which replaced the client's declared capabilities with synthetic profiles. This caused the endpoint to ignore what the client can actually play and return decisions for formats the client never requested (e.g. AAC when the client only supports FLAC/opus/mp3). The override is now gated behind an ApplyServerOverride flag in TranscodeOptions, which is only set by the legacy stream endpoint where this behavior is expected. Signed-off-by: Deluan <deluan@navidrome.org> * refactor: move server-side transcoding override to ResolveRequest Moved the server-side player transcoding override logic (forced format and MaxBitRate cap) from MakeDecision into ResolveRequest, where the legacy stream context is handled. This makes MakeDecision a pure function that only operates on the ClientInfo it receives, removing the ApplyServerOverride flag and all context-sniffing from the decision engine. Tests moved accordingly to legacy_client_test.go. * test(e2e): update transcode decision tests for server override removal Updated e2e tests to reflect that getTranscodeDecision no longer applies server-side player overrides (MaxBitRate cap and forced transcoding profile). The player MaxBitRate tests now verify the endpoint ignores the player cap and relies solely on client-declared capabilities. * test(e2e): assert opus default bitrate when player cap is ignored Added bitrate assertion to verify the player MaxBitRate cap is truly ignored: the target bitrate should be the opus format default (128kbps), not the player cap (320kbps). --------- Signed-off-by: Deluan <deluan@navidrome.org>
