Struct retina::client::Session[][src]

pub struct Session<S: State>(_, _);
Expand description

An RTSP session.

The expected lifecycle is as follows:

  1. Create a session via Session::describe.
  2. Examine the session’s available streams via Session::streams and set up one or more via Session::setup.
  3. Start playing via Session::play.
  4. Get packets via the [futures::stream::Stream] impl on Session<Playing>, or frames via the [futures::stream::Stream] impl returned by Session<Playing>::demuxed.
  5. Drop the session. Retina may issue a TEARDOWN in the background, depending on the [SessionOptions::teardown] parameter.
  6. Possibly wait for TEARDOWN to complete; see SessionOptions::session_group and SessionGroup::await_teardown.

Implementations

Returns the available streams as described the server.

Creates a new session from a DESCRIBE request on the given URL.

This method is permissive; it will return success even if there are errors in the SDP that would prevent one or more streams from being depacketized correctly. If those streams are setup via Session<Described>::setup, the erorrs in question will be ultimately returned from Stream<Playing>::demuxed.

Expects to be called from a tokio runtime.

Sends a SETUP request for a stream.

Note these can’t reasonably be pipelined because subsequent requests are expected to adopt the previous response’s Session. Likewise, the server may override the preferred interleaved channel id and it seems like a bad idea to try to assign more interleaved channels without inspect that first.

Panics if stream_i >= self.streams().len().

Sends a PLAY request for the entire presentation.

The presentation must support aggregate control, as defined in RFC 2326 section 1.3.

Returns a wrapper which demuxes/depacketizes into frames.

Fails if a stream that has been setup can’t be depacketized.

👎 Deprecated since 0.3.1:

Use SessionGroup::await_teardown instead

Sends a TEARDOWN, ending the session.
