Member Function Documentation

GetSampleCount()

virtual int32 IMediaCache::GetSampleCount ( EMediaCacheState  State ) const

inlinevirtual

Query the number of samples for the specified caching state.

Parameters

State

The sample state we're interested in.

Returns

Sample count.

QueryCacheState()

virtual bool IMediaCache::QueryCacheState ( EMediaCacheState  State, TRangeSet< FTimespan > &  OutTimeRanges  ) const

inlinevirtual

Query the time ranges of cached media samples for the specified caching state.

This method can be used to probe a media player's decoder for which samples are scheduled for loading, being loaded, or finished loading. This is generally only supported by those players that expose some kind of internal sample caching or load/decode scheduling mechanism, and most players may simply ignore this call.

Parameters

State	The sample state we're interested in.
OutTimeRanges	Will contain the set of matching sample time ranges.

Returns

true on success, false if not supported.
