Update module github.com/pion/webrtc/v4 to v4.2.6 by renovate[bot] · Pull Request #124 · pion/bwe-test

Special thanks to @AkshayJainG for reporting and diagnosing several panic conditions in the IVF and OGG readers caused by malformed inputs. these fixes improve robustness when handling untrusted or malformed media inputs using ogg reader or ivf reader.

`v4.2.0`

Compare Source

We are pleased to announce our final and largest release of 2025. This release includes contributions from 69 contributors.

This release also marks a new era for Pion. Going forward, we will publish releases on a regular schedule.

Major new features

RACK

We are happy to announce that SCTP now includes a RACK implementation, enabled by default. This work is included in pion/sctp#390 and pion/sctp#438, with a reported 71% improvement in maximum throughput and 27% better latency.

ICE Renomination

Pion now supports ICE renomination It was added in pion/ice#822 and pion/ice#799, and integrated into WebRTC in #3306. It can be enabled via the SettingEngine.

// For advanced use with a custom generator and interval.
se := webrtc.SettingEngine{}

interval := 2 * time.Second
customGen := func() uint32 { return uint32(time.Now().UnixNano()) } // example

if err := se.SetICERenomination(
	webrtc.WithRenominationGenerator(customGen),
	webrtc.WithRenominationInterval(interval),
); err != nil {
	log.Println(err)
}

Cryptex

Pion now supports Cryptex, enabling full encryption of RTP headers and header extensions. This work is included in pion/srtp#324 and pion/sdp#213.

FlexFEC

FlexFEC has been added, is stable, and is ready for production use. See pion/interceptor#333, #3075, pion/interceptor#330, pion/interceptor#344, and pion/interceptor#383.

ICEAddressRewriteRule

Pion’s NAT 1:1 API is now deprecated. After years of use, it no longer fits modern deployment models. This change is implemented in pion/ice#834 and #3309.

The new API, SetICEAddressRewriteRules(rules ...ICEAddressRewriteRule) error, rewrites the IP addresses embedded in gathered ICE candidates.

Rule fields (high level):

External []string: the address or addresses you want to expose
Matchers: Local, CIDR, or Iface
Mode: Replace (default) or Append (keep the original and add the rewritten candidate)
Optional: AsCandidateType (for example, rewrite as srflx)

se := webrtc.SettingEngine{}

_ = se.SetICEAddressRewriteRules(
	webrtc.ICEAddressRewriteRule{
		Local:    "10.0.0.12",
		External: []string{"203.0.113.10"},
		// Mode omitted, defaults to Replace.
	},
)

api := webrtc.NewAPI(webrtc.WithSettingEngine(se))
// pc, _ := api.NewPeerConnection(...)

// For more advanced use.
se := webrtc.SettingEngine{}

se.SetICEAddressRewriteRules(
	// Allow eth0 (map RFC1918 to public 203.0.113.10)
	webrtc.ICEAddressRewriteRule{
		Iface:    "eth0",
		CIDR:     "10.0.0.0/8",
		External: []string{"203.0.113.10"},
		Mode:     webrtc.ICEAddressRewriteReplace,
	},

	// Allow eth1 (map 192.168/16 to public 198.51.100.20)
	webrtc.ICEAddressRewriteRule{
		Iface:    "eth1",
		CIDR:     "192.168.0.0/16",
		External: []string{"198.51.100.20"},
		Mode:     webrtc.ICEAddressRewriteReplace,
	},

	// Catch-all: drop any other IPv4 host candidates
	webrtc.ICEAddressRewriteRule{
		CIDR:     "0.0.0.0/0",
		Mode:     webrtc.ICEAddressRewriteReplace,
		External: nil, // drop
	},

	// Catch-all: drop any other IPv6 host candidates
	webrtc.ICEAddressRewriteRule{
		CIDR:     "::/0",
		Mode:     webrtc.ICEAddressRewriteReplace,
		External: nil, // drop
	},
)

SVT-AV1

Adds a new AV1 video encoder to pion/mediadevices backed by SVT-AV1: pion/mediadevices#660.

HEVC reader and writer

#3171
- pkg/media/h265reader parses an H.265/HEVC Annex-B byte stream (start-code delimited) into NAL units you can work with.
- pkg/media/h265writer takes H.265 RTP payloads (RFC 7798) and writes them back out as an Annex-B bytestream, which is useful for recording and archiving.

New OGG Reader API

A series of improvements to oggreader:
- #3301 adds OpusTags support via ParseOpusTags, enabling access to artist, title, and vendor comments.
- #3299 expands ParseOpusHead to parse Opus channel mappings for multichannel layouts.
- #3300 updates oggreader to handle multi-track Ogg by routing pages by serial and introducing NewWithOptions along with richer page and header APIs.
- #3302 validates the full flow by streaming single-track and multi-track Ogg with a playlist and metadata over DataChannel control, while audio remains on the RTP track.
