Requirements:

Libcurl >= 7.36.0 - the multiprotocol file transfer library with RTSP support http://curl.haxx.se/libcurl/
PugiXML - Light-weight, simple and fast XML parser for C++ http://pugixml.org/ or TinyXML - a simple, small, C++ XML parser http://www.grinninglizard.com/tinyxml/
Glibc >= 2.12 - the GNU C library (recvmmsg) http://www.gnu.org/software/libc/

Description:

This plugin integrates SAT>IP network devices seamlessly into VDR. You can use any SAT>IP channel like any other normal DVB channel for live viewing, recording, etc. The plugin also features full section filtering capabilities which allow for example EIT information to be extracted from the incoming stream.

Installation:

tar -xzf /put/your/path/here/vdr-satip-X.Y.Z.tgz make -C satip-X.Y.Z install

Configuration:

The plugin accepts a "--devices" (-d) command-line parameter defaulting to two. This parameter defines how many simultaneous transponders can be received, if there are available SAT>IP tuners.

The plugin accepts also a "--server" (-s) command-line parameter, that can be used to manually configure static SAT>IP servers if autodetection via UPnP somehow can't be used. Multiple service entries can be given separated by a semicolon:

[srcaddress>@]<ipaddress[:]|[:]|[:];...

srcaddress (Optional) Source address can be used to define used networking interface on a host, e.g. 127.0.0.1.
ipaddress IP address of SAT>IP server, e.g. 127.0.0.1.
port (Optional) IP port number of SAT>IP server, e.g 443.
model Model defines DVB modulation system (DVBS2, DVBT2, DVBT, DVBC) and number of available frontends separated by a hyphen, e.g. DVBT2-4.
filter (Optional) Filter can be used to limit satellite frontends to certain satellite position, e.g. S19.2E.
description Friendly name of SAT>IP server. This is used for autodetection of quirks.

quirk (Optional) Quirks are non-standard compliant features and bug fixes of SAT>IP server defined by a hexadecimal number. Multiple quirks can be defined by combining values by addition:

                   0x01: Fix session id bug
                   0x02: Fix play parameter (addpids/delpids) bug
                   0x04: Fix frontend locking bug
                   0x08: Support for RTP over TCP
                   0x10: Support the X_PMT protocol extension
                   0x20: Support the CI TNR protocol extension
                   0x40: Fix auto-detection of pilot tones bug
                   0x80: Fix re-tuning bug by teardowning a session

Examples:

The plugin accepts a "--portrange" (-p) command-line parameter, that can be used to manually specify the RTP & RTCP port range and therefore enables using the plugin through a NAT (e.g. Docker bridged network). A minimum of 2 ports per device is required.

SAT>IP satellite positions (aka. signal sources) shall be defined via sources.conf. If the source description begins with a number, it's used as SAT>IP signal source selection parameter. A special number zero can be used to disable the source. Otherwise, the default parameter is one:

S19.2E Astra 1KR/1L/1M/2C => Signal source = 1

S19.2E 2 => Signal source = 2

S19.2E 3 Astra 1KR/1L/1M/2C => Signal source = 3

S19.2E 0 Astra 1KR/1L/1M/2C => Source is disabled

A channel can be assigned into a specific SAT>IP frontend by giving the identifier number in RID field of a channels.conf entry: FE = RID % 100 Valid range: 1 ... 99

Setup menu:

Operating mode = off If you want exclude all SAT>IP devices low from VDR's device handling, set this normal option to "off". Otherwise, if you want high to keep SAT>IP at a low priority when selecting available devices, set this option to "low". Similarly, the "high" value prefers the SAT>IP over the local DVB cards when selecting available devices.
Use CI extension = no If you want to use the CI extension found in some SAT>IP hardware (e.g. Digital Devices OctopusNet), set this option to "yes".
CICAM # = If you want to assign a CA system into a specific CI slot, set this option to a named one. Use "---" for autoselection.
Enable EPG scanning = yes If you want exclude all SAT>IP devices from VDR's EIT background scanning, set this option to "no".
Disabled sources = none If your SAT>IP servers don't have certain satellite positions available you can disable them via this option.
Disabled filters = none Certain section filters might cause some unwanted behaviour to VDR such as time being falsely synchronized etc. This option allows creation of blacklists of ill-behaving filters. If this option is set to a non-zero value, the menu page will contain that many "Disable filter" options which allow you to disable the individual section filters. Valid range: "none" = 0 ... 7
Transport mode = unicast If you want to use the non-standard multicast RTP-over-TCP transport mode, set this option rtp-o-tcp accordingly. Otherwise, the transport mode will be RTP-over-UDP via unicast or multicast.
Enable frontend reuse = yes Certain devices might have artifacts if multiple channels are assigned to the same frontend. If you want to avoid such a frontend assignment, set this option to "no".
[Red:Scan] Forces network scanning of SAT>IP hardware.
[Yellow:Devices] Opens SAT>IP device status menu.
[Blue:Info] Opens SAT>IP information/statistics menu.
[Ok] Opens information menu of selected SAT>IP device.

Information menu:

[Red:General] Opens the general information page.
[Green:Pids] Opens the pid statistics page.
[Yellow:Filters] Opens the section filter statistics page.
[Blue:Bits/bytes] Toggles between bits and bytes mode.

Notes:

If you are having problems receiving DVB-S2 channels, make sure your channels.conf entry contains correct pilot tone setting.
The stream id "-1" states about unsuccessful tuning. This might be a result of invalid channel parameters or lack of free SAT>IP tuners.
If the plugin doesn't detect your SAT>IP network device, make sure your setup doesn't have firewalled the UDP port 1900.
Stream decryption requires a separate CAM plugin that works without direct access to any DVB card devices. Also the integrated CAM slots in Octopus Net devices are supported.
Tracing can be set on/off dynamically via command-line switch or SVDRP command.
OctopusNet firmware 1.0.40 or greater recommended.
Inverto OEM firmware 1.17.0.120 or greater recommended. The firmware 1.16.0.120 can be downloaded and installed from their webpage: http://www.inverto.tv/support/ An update to a newer firmware should be offered afterwards.
FRITZ!OS 7.00 or greater recommended for FRITZ!Box Cable devices. Older firmware versions require both PlayPids and ForceLock quirks.
If you are experiencing glitches in the video stream, one possible reason can be buffer overflows in RTP receive sockets. You can verify this by checking "receive buffer errors" counter by running "netstat -s" command. If the counter increases every time a video glitch happens, you should try to tweak the RTP receive buffer size with the "--rcvbuf" (-r) plugin parameter. A good starting point for the buffer size is to double the operating system default value until errors disappear or the maximum value is reached. You can check these values in Linux by checking the kernel parameters: $ cat /proc/sys/net/core/rmem_default $ cat /proc/sys/net/core/rmem_max
