@ -834,6 +834,15 @@ Property list
Returns ``yes`` if the cache is idle, which means the cache is filled as
much as possible, and is currently not reading more data.
``demuxer-cache-duration``
Approximate duration of video buffered in the demuxer, in seconds. The
guess is very unreliable, and often the property will not be available
at all, even if data is buffered.
``demuxer-cache-idle``
Returns ``yes`` if the demuxer is idle, which means the demuxer cache is
filled to the requested amount, and is currently not reading more data.
``paused-for-cache``
Returns ``yes`` when playback is paused because of waiting for the cache.
