[REQUIRED] Use case description
Support DTS-HD passthrough with audio contained in the Matroska container. See #2147 for more context.
Proposed solution
As the container does not explicitly signal DTS-HD vs DTS, we need to inspect the first audio access unit to determine if the audio is in DTS-HD format. See #2147 (comment) for more details.
Alternatives considered
We could add a flag to allow apps to force the extractor to advertise DTS-HD instead of DTS, but it seems preferable to have the extractor determine the media type correctly based on the media, without external information.
