-``cache``
- Network cache fill state (0-100.0).
-
-``cache-size`` (RW)
- Network cache size in KB. This is similar to ``--cache``. This allows
- setting the cache size at runtime. Currently, it's not possible to enable
- or disable the cache at runtime using this property, just to resize an
- existing cache.
-
- This does not include the backbuffer size (changed after mpv 0.10.0).
-
- Note that this tries to keep the cache contents as far as possible. To make
- this easier, the cache resizing code will allocate the new cache while the
- old cache is still allocated.
-
- Don't use this when playing DVD or Blu-ray.
-
-``cache-free`` (R)
- Total free cache size in KB.
-
-``cache-used`` (R)
- Total used cache size in KB.
-
-``cache-speed`` (R)
- Current I/O read speed between the cache and the lower layer (like network).
- This gives the number bytes per seconds over a 1 second window (using
- the type ``MPV_FORMAT_INT64`` for the client API).
-
-``cache-idle`` (R)
- Returns ``yes`` if the cache is idle, which means the cache is filled as
- much as possible, and is currently not reading more data.

Approximate duration of video buffered in the demuxer, in seconds. The
guess is very unreliable, and often the property will not be available

Cache
-----
-``--cache=<kBytes|yes|no|auto>``
- Set the size of the cache in kilobytes, disable it with ``no``, or
- automatically enable it if needed with ``auto`` (default: ``auto``).
- With ``auto``, the cache will usually be enabled for network streams,
- using the size set by ``--cache-default``. With ``yes``, the cache will
- always be enabled with the size set by ``--cache-default`` (unless the
- stream cannot be cached, or ``--cache-default`` disables caching).
-
- May be useful when playing files from slow media, but can also have
- negative effects, especially with file formats that require a lot of
- seeking, such as MP4.
-
- Note that half the cache size will be used to allow fast seeking back. This
- is also the reason why a full cache is usually not reported as 100% full.
- The cache fill display does not include the part of the cache reserved for
- seeking back. The actual maximum percentage will usually be the ratio
- between readahead and backbuffer sizes.
-
-``--cache-default=<kBytes|no>``
- Set the size of the cache in kilobytes (default: 10000 KB). Using ``no``
- will not automatically enable the cache e.g. when playing from a network
- stream. Note that using ``--cache`` will always override this option.
-
-``--cache-initial=<kBytes>``
- Playback will start when the cache has been filled up with this many
- kilobytes of data (default: 0).
-
-``--cache-seek-min=<kBytes>``
- If a seek is to be made to a position within ``<kBytes>`` of the cache
- size from the current position, mpv will wait for the cache to be
- filled to this position rather than performing a stream seek (default:
- 500).
-
- This matters for small forward seeks. With slow streams (especially HTTP
- streams) there is a tradeoff between skipping the data between current
- position and seek destination, or performing an actual seek. Depending
- on the situation, either of these might be slower than the other method.
- This option allows control over this.
-
-``--cache-backbuffer=<kBytes>``
- Size of the cache back buffer (default: 10000 KB). This will add to the total
- cache size, and reserved the amount for seeking back. The reserved amount
- will not be used for readahead, and instead preserves already read data to
- enable fast seeking back.
-
-``--cache-file=<TMP|path>``
- Create a cache file on the filesystem.
-
- There are two ways of using this:
-
- 1. Passing a path (a filename). The file will always be overwritten. When
- the general cache is enabled, this file cache will be used to store
- whatever is read from the source stream.
-
- This will always overwrite the cache file, and you can't use an existing
- cache file to resume playback of a stream. (Technically, mpv wouldn't
- even know which blocks in the file are valid and which not.)
-
- The resulting file will not necessarily contain all data of the source
- stream. For example, if you seek, the parts that were skipped over are
- never read and consequently are not written to the cache. The skipped over
- parts are filled with zeros. This means that the cache file doesn't
- necessarily correspond to a full download of the source stream.
-
- Both of these issues could be improved if there is any user interest.
-
- .. warning:: Causes random corruption when used with ordered chapters or
- with ``--audio-file``.
-
- 2. Passing the string ``TMP``. This will not be interpreted as filename.
- Instead, an invisible temporary file is created. It depends on your
- C library where this file is created (usually ``/tmp/``), and whether
- filename is visible (the ``tmpfile()`` function is used). On some
- systems, automatic deletion of the cache file might not be guaranteed.
-
- If you want to use a file cache, this mode is recommended, because it
- doesn't break ordered chapters or ``--audio-file``. These modes open
- multiple cache streams, and using the same file for them obviously
- clashes.
-
- See also: ``--cache-file-size``.
-
-``--cache-file-size=<kBytes>``
- Maximum size of the file created with ``--cache-file``. For read accesses
- above this size, the cache is simply not used.
-
- Keep in mind that some use-cases, like playing ordered chapters with cache
- enabled, will actually create multiple cache files, each of which will
- use up to this much disk space.
-
- (Default: 1048576, 1 GB.)
+``--cache=<yes|no|auto>``
+ Decide whether to use network cache settings (default: auto).
+
+ If enabled, use the maximum of ``--cache-secs`` and ``--demuxer-max-bytes``
+ for the cache size. If disabled, ``--cache-pause`` and related are
+ implicitly disabled.
+
+ The ``auto`` choice sets this depending on whether the stream is thought to
+ involve network accesses (this is an imperfect heuristic).
``--no-cache``
Turn off input stream caching. See ``--cache``.
