NS_E_TAMPERED_CONTENT

What `NS_E_TAMPERED_CONTENT` means at its owning API

When this result (0xC00D0BBF) appears, the first blocked transition is integrity checks on protected media data or its protection metadata did not validate. In practice, the tampered content media-format check must be reconstructed from the same URL, stream, object generation and call sequence.

Windows Media Format separates the compressed stream profile from the raw input format and from the decoded output selected by a reader. The writer then packetizes samples, applies attributes and optional data-unit extensions, so failure at one boundary does not prove that the ASF container itself is unreadable. In the case of this result, preserve the earliest lower-level result because wrappers can map several different causes to the same HRESULT.

A controlled media-format test

Log 0xC00D0BBF, this result, the exact operation and the first failure time.
Preserve reader or writer object, stream and input numbers, profile identity, sample timestamps, buffer lengths and the first callback or SDK call that returned the code.
Do not reuse a graph, session, reader or metadata object created before the relevant configuration or resource changed.
Perform one isolated test: open the same content with a minimal reader or writer configuration and add the disputed option only after the baseline succeeds.
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 tampered content media-format 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 tampered content media-format check, earlier setup may have succeeded, but integrity checks on protected media data or its protection metadata did not validate was not completed. This is why logs should preserve both the last successful call and this result.

The targeted comparison is open the same content with a minimal reader or writer configuration and add the disputed option only after the baseline succeeds. It changes the disputed precondition without changing the media identity or unrelated machine settings.

Profile and sample evidence

Capture	Why it matters
Owning call	Record the API method, object identity, thread or callback and timestamp for the tampered content media-format check.
Decisive values	reader or writer object, stream and input numbers, profile identity, sample timestamps, buffer lengths and the first callback or SDK call that returned the code.
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 the tampered content media-format check while changing only the rejected precondition.

How to read the next HRESULT

Retest result	Interpretation
The identical call still returns the code	The values governing the tampered content media-format 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.
The call advances to another HRESULT	the tampered content media-format 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

removing protection metadata or modifying the file, which can destroy the evidence and cannot grant rights.
Do not erase the first occurrence by repeatedly retrying; callbacks and reconnects can replace the useful state with a later wrapper error.
Do not publish credentials, protected-content material or complete private URLs. Record redacted identifiers, lengths, hashes and protocol fields needed to reproduce the tampered content media-format check.

Nearby results are not interchangeable

Main distinction: It belongs to format, profile or sample processing, not merely to file-name or network resolution.

Nearby HRESULT	How to compare it
`NS_E_NOT_CONFIGURED`	Compare the owning API and first rejected value; it belongs to a neighboring checkpoint, not automatically to the same cause as it.
`NS_E_PROTECTED_CONTENT`	Use object state and operation order to decide which code is authoritative when both appear in one trace.
`NS_E_AUDIO_CODEC_NOT_INSTALLED`	Retain it separately if it appears only after the condition has cleared.

Technical references

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