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.

In some implementation, the signaling of pres- Sample ; able T at ence of corrupted video frames can come in the form of omission of those corrupted video frames from the media file.
