By default most players do not cache the data they receive from Streamlink.
|
|
|
|
|
Caching can reduce the amount of buffering you run into because the player will

|
|
|
have some breathing room between receiving the data and playing it.

Multi-threaded streaming
|
|
|
|
|
^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
On segmented streaming protocols (such as HLS and HDS) it's possible to use
|
|
|
|
|
multiple threads to potentially increase the throughput.
|

|
|
|
Each stream type has its own option, and these are the ones that are currently available:

.. note::
|
|
|
|
|
|
|
|
|
|
Using 2 or 3 threads should be enough to see an impact on live streams,
|
|
|
|
|
any more will likely not show much effect.
