Players
=======
Transport modes
---------------
There are three different modes of transporting the stream to the player.
.. list-table::
:header-rows: 1
:class: sd-w-100
* - Name
- Description
* - Standard input pipe
- This is the default behavior when there are no other options specified.
* - Named pipe (FIFO)
- See the :option:`--player-fifo` option.
* - HTTP
- See the :option:`--player-http` and :option:`--player-continuous-http` options.
.. note::
Streamlink also allows passing the resolved stream URL through to the player as its first launch argument
when using the :option:`--player-passthrough` option.
This does only work if the player has support the specific streaming protocol built in. The player will then do
all the data fetching on its own while Streamlink will just wait for the player process to end.
Some streaming protocols like DASH can't be passed through to the player.
Player compatibility

prints the error message
VLC is unable to open the MRL 'fd://0'
Use one of the other transport methods instead to work around this.
.. [2] Requires the ``--stdin`` player argument (:option:`--player-args`)
