NS_E_INVALID_INPUT_FORMAT
NS_E_INVALID_INPUT_FORMAT in a format, graph or streaming trace
The relevant condition for 0xC00D0BB8 is the writer or transform has rejected the raw input media type before accepting samples. Diagnose the failing media-format operation directly and avoid inferring the cause only from the visible playback symptom.
Nearby results are not interchangeable
Main distinction: input format describes samples supplied to the writer, while output format describes data exposed by a reader or transform.
| Nearby HRESULT | How to compare it |
|---|---|
NS_E_MSAUDIO_NOT_INSTALLED | the requested Microsoft audio encoder or decoder is not registered for the selected profile |
NS_E_UNEXPECTED_MSAUDIO_ERROR | The Microsoft audio codec was created but failed during configuration or sample processing |
NS_E_INVALID_OUTPUT_FORMAT | The decoded or transformed output media type is not one the selected component can expose |
Failure anatomy
that format stage is reached when the writer or transform has rejected the raw input media type before accepting samples. The caller must not assume that the next filter, packet, session or metadata state exists after this result.
As a controlled comparison, enumerate accepted input formats and change only the raw input media type to one advertised by the selected codec. If the same operation then returns a different HRESULT, diagnose that later result separately.
A controlled media-format test
- Log
0xC00D0BB8, this result, 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.
Profile and sample evidence
| Capture | Why it matters |
|---|---|
| Owning call | Record the API method, object identity, thread or callback and timestamp for the format operation. |
| 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. |
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 condition.

Treat it as resolved only when the same API path succeeds at this stage; success through a different player or cached copy is merely supporting evidence.
