NS_E_INCOMPATIBLE_VERSION
Diagnosing NS_E_INCOMPATIBLE_VERSION in the Windows Media pipeline
This result (0xC00D0BC7) is returned at the content or profile requires a newer Windows Media SDK contract. It identifies the incompatible version media-format check, so troubleshooting should begin with the object and operation that own that checkpoint rather than with a broad player reset.
Where the failure occurs
At the incompatible version media-format check, the component has already accepted the earlier prerequisites but cannot cross the boundary described as the content or profile requires a newer Windows Media SDK contract. That distinction matters: success in opening the file, resolving the host or creating a COM object does not prove that this later operation is valid.
Profile and sample evidence
| Capture | Why it matters |
|---|---|
| Owning call | Record the API method, object identity, thread or callback and timestamp for the incompatible version 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 this result after configuration has changed. |
| First nested result | Keep the earliest codec, COM, socket, DNS, parser or provider status before this result; later UI messages are less specific. |
| Comparison case | Use one known-good resource that exercises the same the incompatible version media-format check while changing only the rejected precondition. |
A controlled media-format test
- Log
0xC00D0BC7, it, the exact operation and the first failure time. - Do not reuse a graph, session, reader or metadata object created before the relevant configuration or resource changed.
- 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 incompatible version media-format check is fixed.
- Confirm the expected next state and retain any new HRESULT as a separate downstream result.
How to read the next HRESULT
| Retest result | Interpretation |
|---|---|
| The identical call still returns the code | The values governing the incompatible version 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 incompatible version 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. |
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_VIDEO_CODEC_ERROR | Compare the owning API and first rejected value; it belongs to a neighboring checkpoint, not automatically to the same cause as it. |
NS_E_INVALIDPROFILE | Use object state and operation order to decide which code is authoritative when both appear in one trace. |
NS_E_OFFLINE_MODE | Retain it separately if it appears only after the condition has cleared. |
Misleading actions
- changing several profile and codec settings at once, which hides the first incompatible field.
- 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 incompatible version media-format check.
