    Abstract: In various implementations, methods, apparatuses, and computer-readable media are described for providing an indication that a file includes corrupted video frames. For example, the file can include an indicator to indicate one or more video frames associated with a particular playing timestamp and playing duration are corrupted. The indicator can also be configured as an unified indicator associated with both corrupted video frames and missing video frames. In some implementation, the signaling of presence of corrupted video frames can come in the form of omission of those corrupted video frames from the media file. In various implementations, modifications and/or additions to one or more existing media streaming schemes can also indicate to a receiver device that a media segment contains missing (or otherwise non-decodable) frames, prior to the receiver device requesting the media segment.
