# If you have two or more VDRs and you like them to mutually share
|
||
|
|
# there DVB cards you might need to apply this patch first.
|
||
|
|
#
|
||
|
|
# This is a modified version of the patch for VDRs with BIGPATCH.
|
||
|
|
# Thanks to p_body@vdrportal.
|
||
|
|
#
|
||
|
|
# IMPORTANT: As this patch does not only modify streamdev-server but
|
||
|
|
# also an exported method of VDR, you will need to
|
||
|
|
#
|
||
|
|
# !!!!! RECOMPILE VDR AND ALL PLUGINS !!!!!
|
||
|
|
#
|
||
|
|
# Why do I need the patch?
|
||
|
|
# --------------------------
|
||
|
|
# Before switching channels VDR will consider all of its devices to
|
||
|
|
# find the one with the least impact. This includes the device provided
|
||
|
|
# by the streamdev-client plugin. Streamdev-client will forward the
|
||
|
|
# request to its server which in turn checks all of its devices. Now if
|
||
|
|
# the server is running streamdev-client, too, the request will again
|
||
|
|
# be forwarded to its server and finally you will endup in a loop.
|
||
|
|
#
|
||
|
|
# What does the patch do?
|
||
|
|
# -----------------------
|
||
|
|
# The patch adds the additional parameter "bool DVBCardsOnly" to VDR's
|
||
|
|
# device selection method cDevice::GetDevice(...). The parameter
|
||
|
|
# defaults to false which gives you the standard behaviour of GetDevice.
|
||
|
|
# When set to true, GetDevice will use only those devices with a card
|
||
|
|
# index < MAXDVBDEVICES, so only real DVB cards will be considered.
|
||
|
|
# Other devices like streamdev-client or DVB cards provided by plugin
|
||
|
|
# (Hauppauge PVR) won't be used.
