NS_E_INVALID_SAMPLING_RATE
A practical diagnostic path for NS_E_INVALID_SAMPLING_RATE
The diagnostic value of this result (0xC00D0BD0) is its location: the audio sample rate is outside the values accepted by the selected codec and profile. That location is the failing media-format operation, not a generic statement that the file or server is unusable.
Profile and sample evidence
| Capture | Why it matters |
|---|---|
| Owning call | Record the API method, object identity, thread or callback and timestamp for that format stage. |
| Values to record | Profile XML or stream configuration, major type, subtype, format block, bitrate, channels, sample rate, frame dimensions and codec enumeration result. |
| 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
0xC00D0BD0, the exact operation and the first failure time. - Preserve profile XML or stream configuration, major type, subtype, format block, bitrate, channels, sample rate, frame dimensions and codec enumeration result before retrying.
- Perform one isolated test: enumerate accepted input formats and change only the raw input media type to one advertised by the selected codec.
- 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 reported failure is fixed.
What completed, and what did not
Before the format operation, earlier setup may have succeeded, but the audio sample rate is outside the values accepted by the selected codec and profile was not completed. This is why logs should preserve both the last successful call and it.
A focused comparison is to enumerate accepted input formats and change only the raw input media type to one advertised by the selected codec before retrying. This isolates the disputed precondition without changing the media identity or unrelated machine settings.
Misleading actions
- Changing several profile and codec settings at once, which hides the first incompatible field.
- Record redacted identifiers, lengths, hashes and protocol fields needed to reproduce the original request.
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_UNSUPPORTED_PROPERTY | The requested property is not supported by the current metadata object or provider. |
NS_E_NO_MORE_SAMPLES | the reader reached the end of the selected range or stream enumeration |
NS_E_MAX_PACKET_SIZE_TOO_SMALL | The configured ASF packet ceiling cannot contain data generated by the profile |

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