NS_E_METADATA_CANNOT_RETRIEVE_FROM_OFFLINE_CACHE
What NS_E_METADATA_CANNOT_RETRIEVE_FROM_OFFLINE_CACHE means at its owning API
When this result (0xC00D32DE) appears, the first blocked transition is offline mode was selected but the cache cannot supply the requested metadata. In practice, the retrieve from offline cache metadata check must be reconstructed from the same URL, stream, object generation and call sequence.
Windows Media metadata can be file-level or stream-level and can come from an ASF header, computed attributes, an online/cache provider or a format-specific metadata handler. Read capability, edit capability, locale and query schema are independent properties. In the case of this result, preserve the earliest lower-level result because wrappers can map several different causes to the same HRESULT.
Read-only metadata experiment
- Log
0xC00D32DE, this result, the exact operation and the first failure time. - Preserve content identifier, cache key, provider, cache timestamp and expiry, requested locale, online/offline mode and the cache lookup result when isolating this case.
- Do not reuse a graph, session, reader or metadata object created before the relevant configuration or resource changed at this checkpoint.
- Perform one isolated test: perform one online metadata retrieval to establish the content identifier, populate the cache, then repeat the identical request offline.
- Repeat through the same API and protocol path; a different player or local-copy test is useful only as a comparison, not as proof that the metadata check is fixed.
- Confirm the expected next state and retain any new HRESULT as a separate downstream result.
What completed, and what did not
Before the metadata check, earlier setup may have succeeded, but offline mode was selected but the cache cannot supply the requested metadata was not completed. This is why logs should preserve both the last successful call and this result.
The targeted comparison is perform one online metadata retrieval to establish the content identifier, populate the cache, then repeat the identical request offline when isolating this case. It changes the disputed precondition without changing the media identity or unrelated machine settings at this checkpoint.
Attribute, schema and locale evidence
| Capture | Why it matters |
|---|---|
| Owning call | Record the API method, object identity, thread or callback and timestamp for the metadata check. |
| Decisive values | Content identifier, cache key, provider, cache timestamp and expiry, requested locale, online/offline mode and the cache lookup result. |
| Object generation | Note when the reader, writer, graph, URL object, streaming session or metadata provider was created; stale state can reproduce it after configuration has changed. |
| First nested result | Keep the earliest codec, COM, socket, DNS, parser or provider status before it; later UI messages are less specific. |
| Comparison case | Use one known-good resource that exercises the same condition metadata check while changing only the rejected precondition. |
Interpret the provider response
| Retest result | Interpretation |
|---|---|
| The identical call still returns the code | The values governing the metadata check are unchanged, or the caller is still using an older object generation. |
| A fresh object succeeds | Lifetime or cached state contributed to it; correct object recreation instead of applying a machine-wide workaround at this checkpoint. |
| The call advances to another HRESULT | the metadata check boundary was cleared. Diagnose the new code at its own format, graph, URL, network or metadata stage. |
| Only one resource fails | The evidence favors content, URL, publishing point, stream, attribute or object-specific state rather than a global outage. |
Misleading actions
- Deleting metadata caches or tags before preserving the provider, attribute key, type and locale that produced the result before closing this incident.
- Do not erase the first occurrence by repeatedly retrying; callbacks and reconnects can replace the useful state with a later wrapper error in the diagnostic record.
- Do not publish credentials, protected-content material or complete private URLs when isolating this case. Record redacted identifiers, lengths, hashes and protocol fields needed to reproduce the metadata check.
Nearby results are not interchangeable
Main distinction: a cache failure does not prove that the online metadata source lacks the item.
| Nearby HRESULT | How to compare it |
|---|---|
NS_E_METADATA_INVALID_DOCUMENT_TYPE | The metadata document type does not match the handler expected for the operation |
NS_E_METADATA_IDENTIFIER_NOT_AVAILABLE | The content identifier needed to correlate metadata is absent |
NS_E_METADATA_CACHE_DATA_NOT_AVAILABLE | The offline or local metadata cache has no matching item |

Retain the post-fix trace so a later pipeline result is not mistaken for recurrence of this boundary in the diagnostic record.
