v0.4.5 (2023-02-02)

  • minimum Rust version is now 1.64.
  • upgrade to rtsp-types 0.0.5, which ignores trailing whitespace in RTSP headers. This fixes errors when communicating with some Longse cameras (#77).
  • remove obsolete workaround for GW security GW security GW4089IP's bad out-of-band parameters. Instead, we treat them as unparseable and ignore them as described in the v0.4.2 notes below.

v0.4.4 (2022-12-26)

  • improve interop with Ubiquiti cameras by ignoring fmtp attributes in SDP which have nothing (no required SP, no data) after the payload type.
  • fix parsing of RTP packets with extensions, which broke with v0.4.0 (2e34bf92).

v0.4.3 (2022-09-28)

  • upgrade version of h264-reader crate. Compatibility note: Retina may now be stricter about parsing H.264 parameters (SPS/PPS). In practice, with some cameras this means unparseable "out-of-line" parameters (specified in the SDP) will be ignored in favor of parseable "in-line" parameters (specified within the RTP data stream).

v0.4.2 (2022-09-28)

v0.4.1 (2022-08-09)

  • Send keepalives at every half-session-timeout rather than a fixed 30-second interval. This allows persistent connections to servers that have timeouts shorter than 30 seconds.
  • Use OPTIONS for initial keepalive, and only switch to SET_PARAMETER if the server advertises its support. This allows persistent connections to rtsp-simple-server v0.19.3, which does not support the latter method and drops the connection on receiving unsupported methods.

v0.4.0 (2022-05-17)

  • BREAKING: remove deprecated retina::client::Session<Playing>::teardown and retina::client::Demuxed::teardown; made private some items already #[doc(hidden)].
  • BREAKING: retina::client::Session<Described>::setup takes a new SetupOptions argument for future expansion.
  • BREAKING: the transport to use is configured per-stream as part of retina::SetupOptions (rather than the prior retina::SessionOptions) and takes per-transport options for future expansion.
  • BREAKING: retina::StreamContext has been split out of retina::PacketContext. Both must be printed to provide the same information as before. This change reduces how much data needs to be copied with each packet.
  • BREAKING: PacketItem and CodecItem are now #[non_exhaustive] for future expansion.
  • BREAKING: retina::client::rtp::Packet is now retina::rtp::ReceivedPacket, and field access has been removed in favor of accessors.
  • BREAKING: retina::client::PacketItem::RtpPacket has been renamed to retina::client::PacketItem::Rtp.
  • BREAKING: retina::client::PacketItem::SenderReport has been replaced with retina::client::PacketItem::Rtcp, to expose full RTCP compound packets. Likewise retina::codec::CodecItem.
  • BREAKING: retina::codec::Parameters is now retina::codec::ParametersRef, which references parameters stored within the Stream to reduce copying.
  • minimum Rust version is now 1.59.

v0.3.10 (2022-05-09)

  • ignore unparseable rtptime values in the PLAY response's RTP-Info header. This improves compatibility with the OMNY M5S2A 2812 camera, as described in scottlamb/moonfire-nvr#224.

v0.3.9 (2022-04-12)

  • camera interop: eliminate bad clockrate in rtpmap errors with cameras that (incorrectly) add trailing spaces to this SDP parameter, as described at scottlamb/moonfire-nvr#213.
  • camera interop: allow ignoring RTSP interleaved data messages on unassigned channels, also described at scottlamb-moonfire-nvr#213.
  • camera interop: when using TCP, default to attempting a TEARDOWN before closing the connection, to improve behavior with cameras that have the live555 stale session bug but do not advertise it.
  • clarify Session's expectations for tokio runtimes.
  • additional diagnostics/logging on certain camera failures.

v0.3.8 (2022-03-08)

  • fix depacketization of fragmented AAC frames
  • #52: allow compatibility with cameras that incorrectly omit the SDP origin line.
  • fix panic if RTSP server precedes a data message with a CRLF.
  • expose SDP framerate via retina::client::Stream::framerate.

v0.3.7 (2022-01-28)

  • #50: fix a panic on certain invalid H.264 sprop-parameter-sets
  • documentation improvements

v0.3.6 (2021-12-29)

  • correctly expire stale session entries that track live555 stale file descriptor sessions. See moonfire-nvr#184.
  • ignore (rather than error on) spurious RTP data packets between the PLAY request and response. These are sent by some versions of v4l2rtspserver.

v0.3.5 (2021-11-30)

  • #42: support servers that don't send out-of-band H.264 parameters or send invalid parameters; wait for in-band parameters in this case. The in-band parameters must be valid.
  • documentation improvements.

v0.3.4 (2021-10-26)

  • use rtsp-types 0.0.3, and thus nom 7.0.

v0.3.3 (2021-10-20)

  • #25: better HTTP authentication support via the new http-auth crate. Before, retina would only authenticate properly if the first requested challenge was Digest. Now, it will pick out a Digest or Basic challenge from a list.

v0.3.2 (2021-09-29)

  • better TEARDOWN handling, which often avoids the need to wait for session expiration ((#34).

v0.3.1 (2021-09-09)

  • warn when connecting via TCP to a known-broken live555 server version.
  • improve Geovision compatibility by skipping its strange RTP packets with payload type 50.
  • UDP fixes.
  • improve compatibility with cameras with non-compliant SDP, including Anpviz (#26 and Geovision ([#33])(scottlamb#33)).
  • new mechanism to more reliably send TEARDOWN requests.

v0.3.0 (2021-08-31)

  • BREAKING CHANGE: #30: experimental UDP support. Several RtspMessageContext fields have been replaced with PacketContext.
  • BREAKING CHANGE: remove retina::client::SessionOptions::ignore_spurious_data. This was an attempted workaround for old live555 servers (#17) that was ineffective.
  • #22: fix handling of 44.1 kHz AAC audio.

v0.2.0 (2021-08-20)

  • BREAKING CHANGE: retina::client::Session::describe now takes a new options: SessionOptions. The creds has moved into the options, along with some new options.
  • BREAKING CHANGE: renamed PlayPolicy to PlayOptions for consistency.
  • Added options to work around bugs found in Reolink cameras.
  • #9. Improve compatibility with how some cameras handle the control and RTP-Info urls. This adopts a URL joining behavior which isn't RFC-compliant but seems to be more compatible in practice.

v0.1.0 (2021-08-13)

  • use SET_PARAMETERS rather than GET_PARAMETERS for keepalives. The latter doesn't work with GW Security GW4089IP cameras.
  • removed rtcp dependency. Fixes #8. Avoids picking up various transitive dependencies needed by later versions of the rtcp crate, including tokio. (retina's own tokio dependency will likely become optional in a future version.)

v0.0.5 (2021-07-08)

  • BREAKING CHANGE: New opaque error type with more uniform, richer error messages. No more failure dependency.
  • BREAKING CHANGE: retina::client::Stream::parameters now returns parameters by value. This allows shrinking depacketizer types.
  • BREAKING CHANGE: retina::codec::VideoFrame::new_parameters is now boxed. This allows shrinking VideoFrame and CodecItem by 80 bytes each (on 64-bit platforms). The box is only rarely populated.
  • in client mp4 example, handle an initial video parameter change correctly.

v0.0.4 (2021-06-28)

  • bugfix: Retina stopped receiving packets after receiving a keepalive response.

v0.0.3 (2021-06-28)

  • BREAKING CHANGE: Session<Playing> now directly implements Stream instead of through pkts().
  • Performance improvements.

v0.0.2 (2021-06-25)

  • BREAKING CHANGE: Video frames are now provided as a single, contiguous Bytes, and H.264 depacketization is more efficient (#4).

v0.0.1 (2021-06-09)

Initial release.
