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.
Windows Media Format separates the compressed stream profile from the raw input format and from the decoded output selected by a reader during a controlled retest. 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 before retrying.
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. |
| Decisive values | Profile XML or stream configuration, major type, subtype, format block, bitrate, channels, sample rate, frame dimensions and codec enumeration result when isolating this failure. |
| 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 media-format check while changing only the rejected precondition. |
A controlled media-format test
- Log
0xC00D0BD0, it, 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.
- Do not reuse a graph, session, reader or metadata object created before the relevant configuration or resource changed in the diagnostic record.
- Perform one isolated test: enumerate accepted input formats and change only the raw input media type to one advertised by the selected codec when isolating this failure.
- 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 boundary 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 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.
The targeted comparison is enumerate accepted input formats and change only the raw input media type to one advertised by the selected codec before retrying. It changes the disputed precondition without changing the media identity or unrelated machine settings in the diagnostic record.
Misleading actions
- Changing several profile and codec settings at once, which hides the first incompatible field when isolating this failure.
- Do not erase the first occurrence by repeatedly retrying; callbacks and reconnects can replace the useful state with a later wrapper error at this checkpoint.
- Do not publish credentials, protected-content material or complete private URLs. Record redacted identifiers, lengths, hashes and protocol fields needed to reproduce the original request.
How to read the next HRESULT
| Retest result | Interpretation |
|---|---|
| The identical call still returns the code | The values governing the recorded format state 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 before retrying. |
| The call advances to another HRESULT | the original boundary boundary was cleared. Diagnose the new code at its own format, graph, URL, network or metadata stage when isolating this failure. |
| Only one resource fails | The evidence favors content, URL, publishing point, stream, attribute or object-specific state rather than a global outage at this checkpoint. |
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 metadata provider rejected this operation checkpoint |
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 in the diagnostic record.
