38 # Now the streams! There are two types of streams; stream (HTTP output)
39 # and udpstream (UDP output). Let's take stream first.
42 # A basic form of stream, with HTTP input. Often, you will need no more than this.
43 # The input must be Metacube framed (VLC can produce this with an option).
44 stream /test.flv src=http://gruessi.zrh.sesse.net:4013/test.flv
46 # Streams can share the same input (the same is reused, no extra bandwidth needed).
47 # force_prebuffer=<number of bytes> is a parameter where we don't start sending
48 # any data to a newly connected client before we can do that many bytes at once.
49 # This is useful for clients that don't properly buffer themselves before starting
50 # playing, e.g., most web browsers and some Flash players when playing from HTTP
52 stream /test-jwplayer.flv src=http://gruessi.zrh.sesse.net:4013/test.flv force_prebuffer=1500000
54 # encoding=metacube means the _output_ will be Metacube framed. This is useful
55 # for sending on to another Cubemap instance.
56 stream /test.flv.metacube src=http://gruessi.zrh.sesse.net:4013/test.flv encoding=metacube
58 # A stream where the input is _not_ Metacube framed. Note that the stream needs to
59 # have no header and be self-synchronizing (like with UDP input below), and most formats
60 # are not like this. A typical example, however, is MPEG-TS.
61 stream /test.ts src=http://gruessi.zrh.sesse.net:4013/test.ts src_encoding=raw
63 # If your input has PTS Metacube2 blocks (currently only generated by
64 # Nageru >= 1.7.2 with MP4 output) and is segmentable (in practice MP4 with the
65 # right tags, again typically generated by Nageru), you can serve HLS fragments
66 # out of Cubemap's regular backlog, with the playlist served at the given URL
67 # (in this case, /stream.m3u8). This allows you to serve video directly to
68 # Mobile Safari (you'll need iOS >= 10 for fMP4 support; older iOS only
69 # supports TS), and also allow rewinding in the stream if your backlog is large
70 # enough. As of April 2018, iOS and hls.js seem to work well, while at least
71 # VLC and mpv appear to be buggy.
73 # hls_frag_duration= sets the maximum fragment size in seconds; the default, 6,
74 # is Apple's default recommendation. Larger fragments will cause more latency but
75 # fewer HTTP requests (less chance of performance problems). (Typically, you'll want
76 # a bit longer backlog than the default of 10 MB, as you won't fit many six-second
77 # fragments into that.) Setting hls_backlog_margin= makes Cubemap not expose any
78 # new fragments that are too far, measured in bytes, from the beginning of the
79 # backlog, in order to reduce the risk of not managing to deliver them before
80 # they rotate out. The default is zero, but you almost certainly want to change that
81 # to be some reasonable fraction of your fragment length.

84 # UDP input. TS is the most common container to use over UDP (you cannot
85 # take any arbitrary container and expect it to work).
86 # backlog_size=<number of bytes> overrides the backlog, which is normally 10 MB.
87 # If clients fall more behind than the backlog (plus the socket buffer),
88 # they will drop data, so if you have extremely high-bitrate streams, you may want
89 # to increase this. Or conversely, if you have little RAM and many streams
90 # (or many servers) you can decrease it.
91 stream /udp.ts src=udp://@:1234 backlog_size=1048576
93 # An example of IPv4 multicast input. Cubemap will subscribe to the given group
94 # and wait for data sent by any sender to the given port.
95 # pacing_rate_kbit=<number of kilobit/sec> will ask the kernel to hard-limit
96 # the TCP transfer rate, including retransmits, to the given speed. (This is a
97 # no-op if you do not use the sch_fq packet scheduler, which is not the default
98 # but can be set in Linux 3.13 and newer using tc.) This is extremely
99 # useful for reducing packet loss and thus including throughput, since it means
100 # that packets arrive smoothly instead of in tight bursts, which will often
101 # overload underbuffered routers and cause drops (imagine receiving a 100 kB
102 # keyframe at 10gig speeds, and then having to meter it out over 5 Mbit ADSL).
103 # The rate should be a bit higher than your stream bitrate to allow for retransmits.
