What does HRESULT 0xC00D115B (NS_E_WMP_CONVERT_FILE_CORRUPT) mean?

NS_E_WMP_CONVERT_FILE_CORRUPT

Diagnosing NS_E_WMP_CONVERT_FILE_CORRUPT during Windows Media library import

NS_E_WMP_CONVERT_FILE_CORRUPT (0xC00D115B) is returned when the import converter found malformed or inconsistent source data.

Identify whether library insertion reached path validation, type detection, plug-in activation, rights evaluation or database update. Record what the Player had already completed because later retries often replace the original evidence. The specific rejected condition is the import converter found malformed or inconsistent source data.

Controlled import comparison

1. Start from the original call and log 0xC00D115B together with its object and operation phase.
2. Collect container parser result, byte offset, file length, header fields, checksums and whether another parser accepts the whole file before changing the machine.
3. Use this single-variable test: remux or regenerate a short sample from the same source and import it through the identical path.
4. Repeat on a fresh object if the original predates a configuration, device or resource change.
5. Validate the expected next operation, not just initial open or object creation.
