For backwards compatibility, there are stubs for PartitionHeadChecker and WithPartitionHeadChecker that do nothing; these should be removed for 4.0. This also fixes a bug with the depacketizer: if no head checker was present, every packet would be considered as a potential partition head, even if it was at the beginning of the buffer. Since a partition head checker is now always present, the bug cannot happen. The tests assume the old bug, which is why the fakePacketizer returns true if headBytes is empty. It would be better to adapt the tests to do the right thing, as in jech/depacketizer. --- go.mod | 2 +- go.sum | 4 +- pkg/media/samplebuilder/samplebuilder.go | 23 ++++------ pkg/media/samplebuilder/samplebuilder_test.go | 44 +++++++++++-------- 4 files changed, 36 insertions(+), 37 deletions(-) diff --git a/go.mod b/go.mod index fd5571d4d78..942591d14e4 100644 --- a/go.mod +++ b/go.mod @@ -12,7 +12,7 @@ require ( github.com/pion/logging v0.2.2 github.com/pion/randutil v0.1.0 github.com/pion/rtcp v1.2.6 - github.com/pion/rtp v1.7.1 + github.com/pion/rtp v1.7.2 github.com/pion/sctp v1.7.12 github.com/pion/sdp/v3 v3.0.4 github.com/pion/srtp/v2 v2.0.5 diff --git a/go.sum b/go.sum index 8e57c03eadb..c176d9e05c9 100644 --- a/go.sum +++ b/go.sum @@ -54,8 +54,8 @@ github.com/pion/randutil v0.1.0/go.mod h1:XcJrSMMbbMRhASFVOlj/5hQial/Y8oH/HVo7TB github.com/pion/rtcp v1.2.6 h1:1zvwBbyd0TeEuuWftrd/4d++m+/kZSeiguxU61LFWpo= github.com/pion/rtcp v1.2.6/go.mod h1:52rMNPWFsjr39z9B9MhnkqhPLoeHTv1aN63o/42bWE0= github.com/pion/rtp v1.7.0/go.mod h1:bDb5n+BFZxXx0Ea7E5qe+klMuqiBrP+w8XSjiWtCUko= -github.com/pion/rtp v1.7.1 h1:hCaxfVgPGt13eF/Tu9RhVn04c+dAcRZmhdDWqUE13oY= -github.com/pion/rtp v1.7.1/go.mod h1:bDb5n+BFZxXx0Ea7E5qe+klMuqiBrP+w8XSjiWtCUko= +github.com/pion/rtp v1.7.2 h1:HCDKDCixh7PVjkQTsqHAbk1lg+bx059EHxcnyl42dYs= +github.com/pion/rtp v1.7.2/go.mod h1:bDb5n+BFZxXx0Ea7E5qe+klMuqiBrP+w8XSjiWtCUko= github.com/pion/sctp v1.7.10/go.mod h1:EhpTUQu1/lcK3xI+eriS6/96fWetHGCvBi9MSsnaBN0= github.com/pion/sctp v1.7.12 h1:GsatLufywVruXbZZT1CKg+Jr8ZTkwiPnmUC/oO9+uuY= github.com/pion/sctp v1.7.12/go.mod h1:xFe9cLMZ5Vj6eOzpyiKjT9SwGM4KpK/8Jbw5//jc+0s= diff --git a/pkg/media/samplebuilder/samplebuilder.go b/pkg/media/samplebuilder/samplebuilder.go index 8e4ed3ab013..e928f14314d 100644 --- a/pkg/media/samplebuilder/samplebuilder.go +++ b/pkg/media/samplebuilder/samplebuilder.go @@ -22,9 +22,6 @@ type SampleBuilder struct { // sampleRate allows us to compute duration of media.SamplecA sampleRate uint32 - // Interface that checks whether the packet is the first fragment of the frame or not - partitionHeadChecker rtp.PartitionHeadChecker - // the handler to be called when the builder is about to remove the // reference to some packet. packetReleaseHandler func(*rtp.Packet) @@ -204,7 +201,7 @@ func (s *SampleBuilder) buildSample(purgingBuffers bool) *media.Sample { var consume sampleSequenceLocation for i := s.active.head;

-### New Release - -Pion WebRTC v3.0.0 has been released! See the [release notes](https://github.com/pion/webrtc/wiki/Release-WebRTC@v3.0.0) to learn about new features and breaking changes. - -If you aren't able to upgrade yet check the [tags](https://github.com/pion/webrtc/tags) for the latest `v2` release. - -We would love your feedback! Please create GitHub issues or join [the Slack channel](https://pion.ly/slack) to follow development and speak with the maintainers. - ----- - ### Usage [Go Modules](https://blog.golang.org/using-go-modules) are mandatory for using Pion WebRTC. So make sure you set `export GO111MODULE=on`, and explicitly specify `/v2` or `/v3` when importing.

When retrieving codecs from the transceiver after changing codec preferences of the transceiver (for example changing the SDPFmtpLine), the filter function was using codec from the media engine. Thus, the change from `SetCodecPreferences` is lost. Fix: ---- - When a match is found (either exact or partial), use the codec from the transceiver instead of media engine. - Based on feedback, add checks to ensure that PayloadType is not set incorrectly (i. e. set with a default of 0). If it is set to 0, use the PayloadType from the media engine, i. e. negotiated value. Testing: -------- - Modify SDPFmtpLine of a codec of a transceiver using `SetCodecPreferences` method of `RTPTransceiver`. - Invoke `GetParamters` of `RTPREceiver` and ensure that `Codecs` has the SDPFmtpLine modification.

The current transceiver for the Simulcast track already had SSRCs set as media has been received. But, tracks read from the SDP only has `rid`.

When track details are gathered, RIDs are fetched using `getRids` which returns a map. A `range` is done on the returned map and RIDs are appended to the `rids` array in `trackDetails`. And then SSRCs are read from SDP and set into the `ssrcs` array of `trackDetails`. As map range order is not guaranteed, some times the RID index and SSRC index in their respective arrays do not match. Due to the mismatch, services like ion-sfu which rely on RID to find the correct spatial layer get confused and end up forwarding the wrong layer. Solution(s): ------------ There are three possible solutions I could think of 1. The simplest is to not populate SSRCs in `trackDetails` if RIDs are available. Let `handleIncomingSSRC` do the SSRC resolution based on RID. According to RFC 8853 (https://www.ietf.org/rfc/rfc8853.pdf), the binding to SSRC should happen using RID. This is the change I have made in this PR. See testing below for browsers tested. 2. Look for `simulcast` attribute in SDP and take the RID ordering from that line in `getRids` if that attribute is available. If not fall back to `rid` attribute. Also, change `getRids` to return an array. But, I cannot find an RFC which defines behaviour when both RID and SSRC are used in `offer`. The question is, "Will the `ssrc` attribute ordering match the `rid` ordering?". If that is not guaranteed, this will run into trouble. This should be easy to do though if we want to go down this route. 3. The hardest option is to change the receiver SSRC based on RID. But, that makes it too complicated (for example if we have to change SSRC binding of a receiver based on received RID, there will be two receivers with the same SSRC binding unless there is some way to swap bindings of receivers) Testing: -------- Tested on Firefox, Firefox 78.15.0esr, Chrome, Ssafari and ensured that Simulcast sender and receiver are in sync for rid/ssrc/spatial layer resolution. --- peerconnection_media_test.go | 54 ------------------------------------ sdp.go | 5 ---- 2 files changed, 59 deletions(-) diff --git a/peerconnection_media_test.go b/peerconnection_media_test.go index ca43817b368..f8ef503b0af 100644 --- a/peerconnection_media_test.go +++ b/peerconnection_media_test.go @@ -1195,58 +1195,4 @@ func TestPeerConnection_Simulcast(t *testing.T) { assertRidCorrect(t) closePairNow(t, pcOffer, pcAnswer) }) - - t.Run("SSRC Based", func(t *testing.T) { - pcOffer, pcAnswer, err := NewAPI(WithMediaEngine(m)).newPair(Configuration{}) - assert.NoError(t, err) - - vp8Writer, err := NewTrackLocalStaticRTP(RTPCodecCapability{MimeType: MimeTypeVP8}, "video", "pion2") - assert.NoError(t, err) - - _, err = pcOffer.AddTrack(vp8Writer) - assert.NoError(t, err) - - ridMap = map[string]int{} - pcAnswer.OnTrack(onTrackHandler) - - assert.NoError(t, signalPairWithModification(pcOffer, pcAnswer, func(sessionDescription string) string { - sessionDescription = strings.Split(sessionDescription, "a=end-of-candidates\r\n")[0] - sessionDescription = filterSsrc(sessionDescription) - - for _, rid := range rids { - sessionDescription += "a=" + sdpAttributeRid + ":" + rid + " send\r\n" - } - sessionDescription += "a=simulcast:send " + strings.Join(rids, ";") + "\r\n" - - return sessionDescription + `a=ssrc:5000 cname:{49d59adc-fae6-407b-8850-2eb4a5e9b76e} -a=ssrc:5001 cname:{49d59adc-fae6-407b-8850-2eb4a5e9b76e} -a=ssrc:5002 cname:{49d59adc-fae6-407b-8850-2eb4a5e9b76e} -a=ssrc:5003 cname:{49d59adc-fae6-407b-8850-2eb4a5e9b76e} -a=ssrc:5004 cname:{49d59adc-fae6-407b-8850-2eb4a5e9b76e} -a=ssrc:5005 cname:{49d59adc-fae6-407b-8850-2eb4a5e9b76e} -a=ssrc-group:FID 5000 5001 -a=ssrc-group:FID 5002 5003 -a=ssrc-group:FID 5004 5005 -` - })) - - for sequenceNumber := uint16(0); !ridsFullfilled(); sequenceNumber++ { - time.Sleep(20 * time.Millisecond) - - for ssrc := 5000; ssrc <= 5004; ssrc += 2 { - header := &rtp.Header{ - Version: 2, - SSRC: uint32(ssrc), - SequenceNumber: sequenceNumber, - PayloadType: 96, - } - - _, err := vp8Writer.bindings[0].writeStream.WriteRTP(header, []byte{0x00}) - assert.NoError(t, err) - } - } - - assertRidCorrect(t) - closePairNow(t, pcOffer, pcAnswer) - }) } diff --git a/sdp.go b/sdp.go index 94c44bffd9b..6b2518879e8 100644 --- a/sdp.go +++ b/sdp.go @@ -189,11 +189,6 @@ func trackDetailsFromSDP(log logging.LeveledLogger, s *sdp.SessionDescription) ( for rid := range rids { simulcastTrack.rids = append(simulcastTrack.rids, rid) } - if len(simulcastTrack.rids) == len(tracksInMediaSection) { - for i := range tracksInMediaSection { - simulcastTrack.ssrcs = append(simulcastTrack.ssrcs, tracksInMediaSection[i].ssrcs...) - } - } tracksInMediaSection = []trackDetails{simulcastTrack} } From 979aefd702bfe50552cd830a084f9bc339e7d7df Mon Sep 17 00:00:00 2001 From: Artur Shellunts Date: Thu, 28 Oct 2021 18:38:48 +0200 Subject: [PATCH 082/162] Update jsfiddle in play-from-disk Add 'copy browser Session Description to clipboard'.

This example connects two PeerConnections over a virtual network and prints statistics about the data traveling over it. ### Usage diff --git a/examples/examples.json b/examples/examples.json index e2a65bde365..082ac587f2c 100644 --- a/examples/examples.json +++ b/examples/examples.json @@ -130,5 +130,11 @@ "link": "rtcp-processing", "description": "The rtcp-processing example demonstrates Pion's RTCP APIs.

Once signalling to remote side is sent, the remote can send media at any time and receiver has to be ready. Like the bug mentions, a negotiation quickly followed by a renegotiation left the RTP receivers of the tracks in the second offer not set up. If the tracks in the renegotiation happen to be simulcast tracks, they are missed as browsers send RID only in the first few packets. The problem can be reproduced by introducing a 1 second delay in Downstream direction in Network Link Conditioner and using a modified version of LiveKit JS SDK sample app to force a double negotiation spaced closely. With this change, onTrack fires, but the unhandled warning from RTCP for the highest layer still happens. But, the track fires almost immediately following that warning (less than 5 ms later). So, all the simulcast layers are available.

ORTC thread on how roles are set https://github.com/w3c/ortc/issues/167#issuecomment-69409953 When remote is ice-lite and there is no answering role set, the answer uses the default which is DTLS client. So 'setup' is set as 'active' and answer sent. But, when DTLS transport is started, it checks the ICE role and sets itself as DTLS server (because remote is lite and hence local agent becomes controlling ICE agent). So, both sides end up being DTLS server and nobody sends client hello. --- peerconnection.go | 17 ++++---- peerconnection_go_test.go | 88 +++++++++++++-------------------------- sdp.go | 10 +++++ 3 files changed, 50 insertions(+), 65 deletions(-) diff --git a/peerconnection.go b/peerconnection.go index b822dba3928..1794e8d41ef 100644 --- a/peerconnection.go +++ b/peerconnection.go @@ -786,8 +786,9 @@ func (pc *PeerConnection) createICETransport() *ICETransport { // CreateAnswer starts the PeerConnection and generates the localDescription func (pc *PeerConnection) CreateAnswer(options *AnswerOptions) (SessionDescription, error) { useIdentity := pc.idpLoginURL != nil + remoteDesc := pc.RemoteDescription() switch { -
