Adobe’s Real-Time Messaging Protocol (RTMP) comprises a family
of network protocols for transporting streams of time-oriented
video, audio, and data messages over IP networks. The URI
schemes that are used to identify, locate, and access streaming
resources in the RTMP family follow the URI Generic Syntax
of RFC 3986, with constraints. This memo describes the syntax
constraints and the access semantics for RTMP family URIs.

<section title="Introduction">
<t>Adobe’s Real-Time Messaging Protocol (RTMP) comprises a family of network
protocols for transporting streams of time-oriented video, audio, and data
messages over IP networks.</t>
<t>The URI schemes that are used to identify, locate, and access streaming
resources in the RTMP family follow the URI Generic Syntax of
<xref target="RFC3986"/>, with constraints.</t>
<t>
RTMP and its TCP-based transport (the RTMP Chunk Stream) are described in the
<xref target="RTMP">RTMP Specification of December 2012</xref>. Errors,
omissions, and ambiguities in that specification are addressed in
<xref target="RTMP-Errata">RTMP Errata and Addenda</xref>. Coordinated interoperable
enhancements to RTMP are described in
<xref target="E-RTMP">Enhanced RTMP</xref>. Transporting RTMP messages over the
<xref target="RFC7016">Secure Real-Time Media Flow Protocol (RTMFP)</xref>
is described in
<xref target="RFC7425">Adobe's RTMFP Profile for Flash Communication</xref>.
</t>
<t>This memo describes the syntax constraints and the access semantics for
RTMP family URIs.</t>
<t>This memo does not address private or undocumented extensions to the RTMP
family for which interoperation is not desired by the extending parties.</t>
<t>The primary operation for dereferencing an RTMP family URI is to connect
to the indicated origin server and its abstract <em>target resource</em>.
Neither the connection itself nor the target resource have a "representation"
or a "media type" in the senses described in RFC 3986, nor is a "retrieval"
performed by connecting.</t>
<t>The target resource can have secondary resources, such as streams, shared
objects, and remote procedures, that can be accessed according their kinds
via the connection. For example, streams may be published or played, shared
objects updated or observed, and remote procedures called.</t>

<section title="Syntax">
<t>RTMP family URIs follow the Generic Syntax of <xref target="RFC3986"/>,
with constraints. Their syntax is described here using the
<xref target="RFC5234">Augmented Backus-Naur Form (ABNF)</xref> rules from
RFC 3986, which are incorporated by reference as though fully set forth here.
The <tt>host</tt> rule is also reproduced here for clarity in the following
sections. Note that the <tt>rtmp-authority</tt> rule defined here is compatible
with the <tt>authority</tt> rule, and <tt>rtmp-userinfo</tt> is compatible
with the <tt>userinfo</tt> rule.</t>

</section> <!-- Syntax -->
<section title="Authority">
<t>The <tt>rtmp-authority</tt> component, when present, identifies the location
of an RTMP origin server which governs a namespace of target and secondary
resources.</t>
<t>Note: The bare RTMFP URI form "<tt>rtmfp:</tt>" does not have an
<tt>rtmp-authority</tt> component (or any other components). All of the other
URI forms do. The bare "<tt>rtmfp:</tt>" URI is used in the APIs of some
implementations to indicate instantiation of an RTMFP client according to
<xref target="RFC7425"/>, but without connecting to a server. Such an
instantiation might be used for pure peer-to-peer communication.</t>
<section title="Host and Port">
<t> The <tt>host</tt> and optional <tt>port</tt> components locate the origin
server in the network. The <tt>host</tt> component of the <tt>rtmp-authority</tt>
<bcp14>MUST NOT</bcp14> be empty.</t>
<t>For an <tt>rtmp-URI</tt>, the <tt>host</tt> and optional <tt>port</tt>
identify a potential origin server listening for <xref target="RFC0793">TCP</xref>
connections, over which RTMP messages are to be sent using the RTMP Chunk
Stream as described in the <xref target="RTMP">RTMP Specification</xref>. If
the <tt>port</tt> is empty or not given, TCP port <tt>1935</tt> is the
default.</t>
<t>For an <tt>rtmps-URI</tt>, the <tt>host</tt> and optional <tt>port</tt>
identify a potential origin server listening for TCP connections and capable
of establishing a <xref target="RFC8446">TLS</xref> connection secured for
<xref target="RTMP">RTMP Chunk Stream communication</xref>. "Secured" means
a connection that is authenticated, confidential, and integrity-protected in
a manner acceptable to both the client and server. If the <tt>port</tt> is
empty or not given, TCP port <tt>443</tt> is the default.</t>
<t>For an <tt>rtmfp-URI</tt> where the <tt>rtmp-authority</tt> is present,
the <tt>host</tt> and optional <tt>port</tt> identify one or more initial
candidate addresses with which to initiate an <xref target="RFC7016">RTMFP</xref>
connection according to <xref target="RFC7425"/>. The
<xref target="RFC0768">UDP</xref> port for the initial candidate addresses,
if empty or not specified, is <tt>1935</tt>. If <tt>host</tt> is a
<tt>reg-name</tt>, the initial candidate address set <bcp14>SHOULD</bcp14>
comprise all IPv4 and IPv6 addresses to which <tt>reg-name</tt> resolves.</t>
</section> <!-- Host and Port -->
<section title="Userinfo">
<t>When connecting to an RTMP server, the <tt>connect</tt> command
(Section 7.2.1.1 of <xref target="RTMP"/>) can accept or expect additional
arguments following the <em>Command Object</em>. The number and types of the
additional arguments, their interpretation, and whether they are expected is
implementation-specific and is the prerogative of the server.</t>
<t>Often the server expects one or more string arguments to the <tt>connect</tt>
command following the <em>Command Object</em>, for example a developer key,
a user name and password, or implementation-specific connection properties.</t>
<t>If the <tt>rtmp-authority</tt> contains an <tt>rtmp-userinfo</tt> component,
and in the absence of other arrangements between the client and server, the
<tt>rtmp-userinfo</tt> <bcp14>SHOULD</bcp14> be interpreted as a "<tt>:</tt>"
(<tt>COLON</tt>) separated sequence of potentially empty <tt>rtmp-connect-arg</tt>
strings (as illustrated in the ABNF) to be sent as string arguments to the
<tt>connect</tt> command following the <em>Command Object</em>. Each
<tt>rtmp-connect-arg</tt> <bcp14>SHOULD</bcp14> be percent-decoded before
being sent.</t>
<t>Clients <bcp14>SHOULD</bcp14> remove the <tt>rtmp-userinfo</tt> component
from the URI when sending it as the <tt>tcUrl</tt> property of the <tt>connect</tt>
command’s <em>Command Object</em> or in the Ancillary Data option of an RTMFP Endpoint Discriminator
(<xref target="RFC7425" section="4.4.2.2" sectionFormat="of"/>).</t>
</section> <!-- Userinfo -->
</section> <!-- Authority -->
<section title="Path and Query">
<t>The <tt>path-abempty</tt> and <tt>query</tt> components identify the
abstract <em>target resource</em> within the origin server’s namespace. The
meaning of "target resource" is implementation-specific and is the prerogative
of the origin server.</t>
<t>Interoperability Note: Some client implementations incorrectly presume the
server’s interpretation of the <tt>path-abempty</tt> component of the URI,
specifically by presuming the number of path segments that identify the target
resource. These clients then incorrectly interpret the remaining path segments
of the original URI as identifying a secondary resource (such as the name of
a stream to play or publish via the connection to the target resource). This
behavior is not in keeping with the spirit of URIs (particularly that the
<tt>authority</tt> governs its namespace), is not interoperable, and is
<bcp14>NOT RECOMMENDED</bcp14>. Such secondary resources, when encoded in a
URI, should instead be identified by the fragment identifier as described in
the next section.</t>
</section> <!-- Path and Query -->
<section title="Fragment Identifier">
<t><xref target="RFC3986" section="3.5" sectionFormat="of"/> describes the
<tt>fragment</tt> component of a generic URI as allowing "indirect identification
of a secondary resource by reference to a primary resource and additional
identifying information".</t>
<t>Since an RTMP connection to a target resource has neither a "representation"
nor a "media type", the semantics of the <tt>fragment</tt> component are
unconstrained according to that section.</t>
<t>Often an RTMP client connects to a server to perform a specific operation
on a specific secondary resource, such as to publish to or play from a named
stream. In cases where the kind of secondary resource and the intended
operation are unambiguous, and in the absence of other arrangements between
the client and server, the secondary resource <bcp14>MAY</bcp14> be identified
by the <tt>fragment</tt> component. The <tt>fragment</tt> <bcp14>SHOULD</bcp14>
be percent-decoded before being used in secondary resource APIs (for example
in a stream <tt>play</tt> command).</t>
<t>Clients <bcp14>SHOULD</bcp14> remove the <tt>fragment</tt> component from
the URI when sending it as the <tt>tcUrl</tt> property of the <tt>connect</tt>
command’s <em>Command Object</em> or in the Ancillary Data option of an RTMFP
Endpoint Discriminator
(<xref target="RFC7425" section="4.4.2.2" sectionFormat="of"/>).</t>

<dt>URI scheme semantics:</dt>
<dd>
<t>The scheme-only form is used in the APIs of some implementations
to indicate instantiation of an RTMFP client according to RFC
7425, but without connecting to a server. Such an instantiation
might be used for pure peer-to-peer communication.</t>
<t>The full form provides location information for the RTMFP
server to which to connect, and identifies a target resource
and an optional secondary resource in the namespace of the
server. Connections are made using RTMFP (RFC 7016) as
described by RFC 7425. The host component of the authority
<bcp14>MUST NOT</bcp14> be empty. If host is a <tt>reg-name</tt>,
the initial candidate address set <bcp14>SHOULD</bcp14>
comprise all IPv4 and IPv6 addresses to which <tt>reg-name</tt>
resolves. The UDP port for the initial candidate addresses
for the server, if not specified, is 1935.</t>

information regarding the semantics of this URI scheme.</t>
