NS_E_MAX_PACKET_SIZE_TOO_SMALL
What NS_E_MAX_PACKET_SIZE_TOO_SMALL means at its owning API
When this result (0xC00D0BD1) appears, the first blocked transition is the configured ASF packet ceiling cannot contain data generated by the profile. In practice, the packet size too small media-format check must be reconstructed from the same URL, stream, object instance and call sequence.
A controlled media-format test
- Log
0xC00D0BD1, this result, the exact operation and the first failure time. - Preserve ASF packet number, packet size, send and receive timestamps, sequence number, jitter window and the profile packet-size setting.
- Perform one isolated test: load a known-good profile for the same codec, then reintroduce the disputed profile field one setting at a time.
- 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 this condition media-format check is fixed.
What completed, and what did not
Before this condition media-format check, earlier setup may have succeeded, but the configured ASF packet ceiling cannot contain data generated by the profile was not completed. This is why logs should preserve both the last successful call and this result.
A focused comparison is to load a known-good profile for the same codec, then reintroduce the disputed profile field one setting at a time. This isolates the disputed precondition without changing the media identity or unrelated machine settings.
Profile and sample evidence
| Capture | Why it matters |
|---|---|
| Owning call | Record the API method, object identity, thread or callback and timestamp for this condition media-format check. |
| Values to record | ASF packet number, packet size, send and receive timestamps, sequence number, jitter window and the profile packet-size setting. |
| Object instance | Note when the reader, writer, graph, URL object, streaming session or metadata provider was created; stale state can reproduce it after configuration has changed. |
| Comparison case | Use one known-good resource that exercises the same condition 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 this condition media-format check.
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_NO_MORE_SAMPLES | the reader reached the end of the selected range or stream enumeration |
NS_E_INVALID_SAMPLING_RATE | The audio sample rate is outside the values accepted by the selected codec and profile |
NS_E_LATE_PACKET | a network packet missed the useful playout or reordering window |

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