3.2 Usage VDR-to-VDR server:
|
||||
3.2 Usage IGMP multicast server:
|
||||
--------------------------------
|
||||
|
||||
IGMP based multicast streaming is often used by settop boxes to receive IP TV.
|
||||
Streamdev's multicast server allows you to feed live TV from VDR to such a
|
||||
settop box. VLC is known to work well if you look for a software client.
|
||||
|
||||
The advantage of multicasting is that the actual stream is sent out only once,
|
||||
regardless of how many clients want to receive it. The downside is, that you
|
||||
cannot simply multicast across network boundaries. You need multicast routers.
|
||||
For multicast streaming over the public Internet you would even need to register
|
||||
for your own IP range. So don't even think of multicasting via Internet with
|
||||
streamdev! Streamdev will send the stream only to one local ethernet segment and
|
||||
all clients must be connected to this same segment. There must not be a router
|
||||
inbetween. Also note that the client must not run on the streamdev-server
|
||||
machine.
|
||||
|
||||
Each channel is offered on a different multicast IP. Channel 1 is available from
|
||||
multicast IP 239.255.0.1, channel 2 from 239.255.0.2 and so on. The upper limit
|
||||
is 239.255.254.255 which corresponds to channel 65279 (239.255.255.0/24 is
|
||||
reserved according to RFC-2365).
|
||||
|
||||
Before you can use streamdev's multicast server, you might need to patch VDR.
|
||||
Binding an IGMP socket is a privileged operation, so you must start VDR as root.
|
||||
If you pass the -u option to VDR, it will drop almost all priviledges before
|
||||
streamdev is even loaded. Apply vdr-cap_net_raw.diff to keep VDR from dropping
|
||||
the CAP_NET_RAW capability required to bind the IGMP socket. The patch is part
|
||||
of streamdev's source distribution. Check the patches subdirectory. There's no
|
||||
need to patch VDR if it is kept running as root (not recommended).
|
||||
|
||||
The multicast server is disabled by default. Enter the streamdev-server setup
|
||||
menu to enable it and - IMPORTANT - bind the multicast server to the IP of your
|
||||
VDR server's LAN ethernet card. The multicast server will refuse to start with
|
||||
the default bind adresse "0.0.0.0".
|
||||
|
||||
Now edit your streamdevhosts.conf. To allow streaming of all channels, it must
|
||||
contain "239.255.0.0/16". Note that you cannot limit connections by client IP
|
||||
here. You can however restrict which channels are allowed to be multicasted.
|
||||
Enter individual multicast IPs instead of "239.255.0.0/16".
|
||||
|
||||
By default, the linux kernel will refuse to join more than 20 multicast groups.
|
||||
You might want to increase this up to "number_of_channels + 1". Note that it's
|
||||
"number_of_channels", not "maximum_channel_number".
|
||||
|
||||
#First 100 channels:
|
||||
bash# sysctl -w sys.net.ipv4.igmp_max_memberships=101
|
||||
|
||||
#All channels:
|
||||
bash# COUNT=$(grep -c '^[^:]' PATH_TO_YOUR/channels.conf)
|
||||
bash# sysctl -w sys.net.ipv4.igmp_max_memberships=$COUNT
|
||||
|
||||
A multicast server never knows how many clients are actually receiving a stream.
|
||||
If a client signals that it leaves a multicast group, the server has to query
|
||||
for other listeners before it can stop the stream. This may delay zapping from
|
||||
one transponder to an other. The client will probably requests the new channel
|
||||
before the previous stream has been stopped. If there's no free DVB card, VDR
|
||||
won't be able to fulfill the request until a DVB card becomes available and the
|
||||
client resends the request.
