NS_E_INVALID_FILE_BITRATE
Diagnostic meaning beyond the standard text
For NS_E_INVALID_FILE_BITRATE (0xC00D1BD1), the actionable event is file-transfer stream bitrate is invalid for the profile.
Why the session can reach this point
A Windows Media Encoder profile declares content types and one or more audiences. Each audience maps source indexes to audio, video, script or file streams and must remain structurally consistent with the other audiences in a multiple-bit-rate profile.
Individual fields may be syntactically valid while the complete profile is inconsistent across audiences or does not match the source group. One concrete way to reach the condition is that the file bitrate exceeds the total bitrate of the smallest audience.
Decision path
- Record
0xC00D1BD1, the Encoder version and the exact API call or property access that returned it. - Export the current
.wmeor.prxconfiguration, then capture file bitrate, audience total and file-source configuration. - Verify the profile, audience and stream topology precondition without changing the source, profile and output sink at the same time.
- Run one controlled comparison that changes only the identified precondition: set a supported nonnegative allocation that fits the audience.
Codes with similar symptoms but different owners
| Result | Why it differs |
|---|---|
NS_E_MULTIPLE_FILE_BITRATES | file-transfer stream bitrate differs across audiences |
NS_E_AUDIENCE__LANGUAGE_CONTENTTYPE_MISMATCH | different-language streams in one audience do not share compatible media properties |
NS_E_INVALID_SCRIPT_BITRATE | script-stream bitrate is outside the accepted range |
Safe recovery
Set a supported nonnegative allocation that fits the audience.
Do not repair a profile by deleting arbitrary audiences; export the .prx profile first and compare the same source index across every audience.
Discriminating evidence: Measure the file-transfer stream bitrate assigned to each audience and compare it with that audience's total bitrate budget. Record the source index and configured bits per second; this result is specifically about file-stream bitrate allocation, not pixel geometry, profile naming, or the presence of a source index.
