[vlc-devel] [RFC PATCH 1/2] Add dedicated network-caching for live sources

[Julian Scheel]

It can be helpful to have different amount of network caching configured for
live vs non-live (and thus seekable) sources. While for seekable sources it
might be required to have a slightly larger buffering for seeking to actually
be smooth it can be desirable to have a shorter caching for live sources at
the same time. As network-caching is not changeable within a libvlc session
split it into two settings which can be used by the access and demux modules
accordingly.
