MILERR_MROW_UPDATE_FAILED
MILERR_MROW_UPDATE_FAILED is a Windows Media Integration Layer (MIL) HRESULT. It indicates that an update to a shared rendering resource conflicts with an outstanding update operation.
Diagnostic discriminator: Correlate overlapping update submissions to the same shared resource. Serialize one update and repeat with identical content; success on the serialized path identifies concurrent or duplicate update scheduling as the relevant state.
What to check for MILERR_MROW_UPDATE_FAILED
- Serialize updates to the affected resource and wait for the previous update to complete.
- Check for duplicate composition updates submitted from independent callbacks or threads.
- Coalesce frequent changes so only the latest required update is applied after the resource is writable.
