Diagnosing NS_E_WMP_JPG_UNEXPECTED_ENDOFFILE
0xC00D103D maps to this result. Its actionable interpretation is the JPEG byte stream ends before the decoder reaches the markers needed to finish the image within the skin artwork decoder and raster-file contract; the producing mechanism is the image-loading path used by Windows Media Player skins to identify GIF, PNG, BMP or JPEG data, validate format-specific headers and create a bitmap usable by a UI control.
Evidence that separates the result
| Field | What to record |
|---|---|
| What to verify | Record file length, final complete marker and the marker or scan data being read at EOF |
| Artifact identity | Standalone decode result outside the skin package using the same bytes for the JPEG unexpected end of file reproduction |
| Runtime state | Archive member name, byte length, hash and file signature for this reproduction |
| Owning object | Format header fields, dimensions, bit depth and color model for this reproduction |
| Lower-level result | First invalid marker/chunk and its byte offset for this reproduction |
| Correlation | Decoder-supported coding mode versus the file’s declared mode for this reproduction |
Representative case: A partially copied JPEG ends in compressed scan data before the expected end marker.
Focused test and correction
- Confirm the failure directly: record file length, final complete marker and the marker or scan data being read at EOF.
- After you replace the truncated JPEG from an intact source or regenerate it, recreate the owning WMP object and verify that the corrected generation completes.
Nearby results with different conditions
| Result | Different condition |
|---|---|
NS_E_WMP_JPG_IMAGE_TOO_BIG | The JPEG dimensions exceed the decoder’s accepted image-size boundary |
NS_E_WMP_JPG_SOF_UNSUPPORTED | The JPEG frame marker selects an unsupported coding process |
NS_E_WMP_JPG_FRACT_SAMPLE_NOTIMPL | The JPEG uses fractional sampling behavior not implemented by the WMP decoder |
Verification
Repeat the original operation with a fresh owning object after the identified precondition is corrected.
