C00D11B1 error is a problem that occurs when Windows Media Player fails to process the set of files associated with your system’s codec. It is also likely that this error will appear if there are issues with the files required by codec to run. A “codec” is a software or hardware that compresses/decompresses audio and video data streams. Its purpose is to decrease the size of the digital audio and video frames to fast track the transmission and save memory space. With this, the error usually comes up when users attempt to stream an audio or video file from the internet. As this happens, the application cannot be further used.
