Abstract
Innovations in the area of sample metadata processing can help a media playback tool avoid loss of synchronization between sample metadata and media samples. For example, a media playback tool identifies encoded data and sample metadata for a current media sample, then couples the sample metadata with the current media sample. The media playback tool provides the sample metadata and encoded data for the current media sample to a media decoder, which maintains the coupling between at least one element of the sample metadata and the current media sample during at least one stage of decoding, even when the current media sample is dropped, delayed, split, or repeated. For example, the media playback tool can determine whether to drop the current media sample and, if the current media sample is dropped, also drop the sample metadata that is coupled with the current media sample.
