NS_E_INVALID_NUM_PASSES
Investigating NS_E_INVALID_NUM_PASSES without losing the first failure
This result (0xC00D0BD5) marks the application used a preprocessing-pass sequence incompatible with the output mode. The code belongs to the failing media-format operation, which is why a later network, codec or metadata error must be recorded separately instead of replacing it.
Where the failure occurs
At that format stage, the component has already accepted the earlier prerequisites but cannot cross the boundary described as the application used a preprocessing-pass sequence incompatible with the output mode. 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.
For the strongest reproduction, run the exact pass sequence required by the output mode and compare it with the failing callback order. If the same call gets past this point after that single change, the changed precondition is relevant. If it does not, return to the first nested error instead of broadening the repair.
Profile and sample evidence
| Capture | Why it matters |
|---|---|
| Owning call | Record the API method, object identity, thread or callback and timestamp for the original request. |
| Values to record | Source time range, pass number, preprocessing state, EDL entries in source order and the output mode selected for the stream. |
| Comparison case | Use one known-good resource that exercises the same media-format check while changing only the rejected precondition. |
A controlled media-format test
- Log
0xC00D0BD5, the exact operation and the first failure time. - Preserve source time range, pass number, preprocessing state, EDL entries in source order and the output mode selected for the stream.
- Perform one isolated test: run the exact pass sequence required by the output mode and compare it with the failing callback order.
- 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 recorded format state is fixed.
- Confirm the expected next state and retain any new HRESULT as a separate downstream result before retrying.
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_DUPLICATE_PACKET | the receiver recognized a packet sequence that had already been accepted |
NS_E_SDK_BUFFERTOOSMALL | the caller-provided output buffer is smaller than the size reported by the SDK |
NS_E_ATTRIBUTE_READ_ONLY | the caller attempted to modify an attribute whose value is owned or computed by the SDK |
Misleading actions
- Changing several profile and codec settings at once, which hides the first incompatible field.
- Do not publish credentials, protected-content material or complete private URLs before retrying. Record redacted identifiers, lengths, hashes and protocol fields needed to reproduce the original condition.

Close the incident only after the original operation succeeds on a current object and the expected next state is observed.
