# Now the streams! There are two types of streams; stream (HTTP output)
# and udpstream (UDP output). Let's take stream first.
#
# A basic form of stream, with HTTP input. Often, you will need no more than this.
# The input must be Metacube framed (VLC can produce this with an option).
stream /test.flv src=http://gruessi.zrh.sesse.net:4013/test.flv
# Streams can share the same input (the same is reused, no extra bandwidth needed).
# force_prebuffer=<number of bytes> is a parameter where we don't start sending
# any data to a newly connected client before we can do that many bytes at once.
# This is useful for clients that don't properly buffer themselves before starting
# playing, e.g., most web browsers and some Flash players when playing from HTTP
# (e.g., JW Player).
stream /test-jwplayer.flv src=http://gruessi.zrh.sesse.net:4013/test.flv force_prebuffer=1500000
# encoding=metacube means the _output_ will be Metacube framed. This is useful
# for sending on to another Cubemap instance.
stream /test.flv.metacube src=http://gruessi.zrh.sesse.net:4013/test.flv encoding=metacube
# A stream where the input is _not_ Metacube framed. Note that the stream needs to
# have no header and be self-synchronizing (like with UDP input below), and most formats
# are not like this. A typical example, however, is MPEG-TS.
stream /test.ts src=http://gruessi.zrh.sesse.net:4013/test.ts src_encoding=raw
# UDP input. TS is the most common container to use over UDP (you cannot
# take any arbitrary container and expect it to work).
# backlog_size=<number of bytes> overrides the backlog, which is normally 10 MB.
# If clients fall more behind than the backlog (plus the socket buffer),
# they will drop data, so if you have extremely high-bitrate streams, you may want
# to increase this. Or conversely, if you have little RAM and many streams
# (or many servers) you can decrease it.
stream /udp.ts src=udp://@:1234 backlog_size=1048576
# An example of IPv4 multicast input. Cubemap will subscribe to the given group
# and wait for data sent by any sender to the given port.
# pacing_rate_kbit=<number of kilobit/sec> will ask the kernel to hard-limit
# the TCP transfer rate, including retransmits, to the given speed. (This is a
# no-op if you do not use the sch_fq packet scheduler, which is not the default
# but can be set in Linux 3.13 and newer using tc.) This is extremely
# useful for reducing packet loss and thus including throughput, since it means
# that packets arrive smoothly instead of in tight bursts, which will often
# overload underbuffered routers and cause drops (imagine receiving a 100 kB
# keyframe at 10gig speeds, and then having to meter it out over 5 Mbit ADSL).
# The rate should be a bit higher than your stream bitrate to allow for retransmits.
stream /udp-multicast.ts src=udp://@233.252.0.2:1234 pacing_rate_kbit=2000
# IPv6 SSM (Single Source Multicast) input. Subscribes to the given group and
# waits for packets from the given sender only. SSM is nicer than ASM in that
# it does not require a Rendezvous Point (RP) and other complexity, but is
# often poorly supported in various network equipment.
stream /udp-multicast-ssmv6.ts src=udp://[2001:67c:29f4::32]@[ff3e::1000:0]:1234 pacing_rate_kbit=20000
# udpstream takes src= inputs just like stream does, but instead of waiting
# for TCP connections on ports, it immediately sends the packets out over UDP.
# (As with UDP input, this probably only works well for TS mux.)
udpstream [2001:67c:29f4::50]:5000 src=http://pannekake.samfundet.no:9094/frikanalen.ts.metacube
# udpstream takes pacing_rate_kbit= just like stream. None of the other options
# make sense.
udpstream 193.35.52.50:5001 src=http://pannekake.samfundet.no:9094/frikanalen.ts.metacube pacing_rate_kbit=2000
# IPv4 multicast output, to the given group. You can explicitly set the TTL
# and/or multicast output interface, if the defaults do not suit you.
udpstream 233.252.0.1:5002 src=http://pannekake.samfundet.no:9094/frikanalen.ts.metacube ttl=32 multicast_output_interface=eth1
# A type of HTTP resource that is not a stream, but rather just a very simple
# document that a HTTP 204 response and nothing else. allow_origin= is optional;
# if it is set, the response will contain an Access-Control-Allow-Origin header
# with the given value, allowing the ping response to be read (and
# differentiated from an error) from a remote domain using XHR.
#
# If you have a stream and a gen204 endpoint with the same URL, the stream takes
# precedence and the ping endpoint is silently ignored.
gen204 /ping allow_origin=*
