The GStreamer team is pleased to announce another development snapshot in the API/ABI-unstable 1.29 release series.

The API/ABI-unstable 1.29 release series is for testing and development purposes in the lead-up to the stable 1.30 series which is scheduled for release in Q4 2026. Any newly-added API can still change until that point.

This development release is primarily for developers and early adopters, and distros should probably not package it.

Highlighted changes:

• webrtcbin2: New scalable WebRTC bin that uses fewer threads and native Rust DTLS, ICE and RTP session management implementations
• rtspsrc2: implement support for SRTP, authentication, HTTP tunnelling, keep alive, stream selection, TLS validation, latency configuration
• rtp2: New Rust RTP payloader and depayloader implementations for MPA audio, MPEG-2 video and raw video
• Digitally Signed Content (DSC) support, initially for H.266 video
• New D3D12-based element which performs color lookup operations using user-provided Adobe .cube LUT files
• videoencoders: Support adaptive presets with resolution-dependent properties and implement in x264enc and nvh264enc
• closedcaption: add h266seiinserter; add "do-timestamp" property to codecseiiinserter
• flv: Add support for AV1 video
• v4l2: add capture timestamps to buffers in v4l2src, and "bitrate" and "gop-size" properties to video encoders
• applemedia: new iosurface helper library providing a memory:IOSurface abstraction
• AMF: add super resolution hq-scaler component
• New OpenGL glalphacombine element for RGBA inputs and Vulkan/OpenGL memory support for alphacombine
• openjpeg: Add support for high bit depth formats
• analytics: add semantic tag getter to GstAnalyticsMtd
• tensordecoders: Add YOLO26 detection decoder
• tfliteinference: support for external delegates, XNNPACK, and GRAY8 input
• MP4: add support for losslessly-compressed video
• matroskamux: add TrueHD audio and HDMV PGS subpicture support
• playsink reconfiguration stability improvements
• New agingradio and sofalizer audio effect elements
• New image-rs based imagersoverlay element in Rust to replace gdkpixbufoverlay
• webrtcsink: add v4l2h264enc (Raspberry Pi) encoder support and a signaller for Unreal Engine PixelStreaming
• webrtcsink, webrtcsource: make custom signalling protocol extendable
• Speech elements: implement support for non-synchronized output
• d3d12: Add support for hardware-accelerated decoding of VP9 with alpha
• androidmedia: New source element for Android assets
• filesink: Add support for Windows file sharing mode to allow reading of file while it's being written to
• tracing: custom spans and events API and new tracers that integrate with the Rust tracing ecosystem
• editing-services: auto-plug raw video converters from the registry based on compositor memory family and prepare for multi-threaded usage
• dots-viewer: General enhancement of the web app
• New viuersink video sink that plays video in the terminal, replacing aasink and cacasink
• cerbero: Added ccache support for MSVC
• Countless bug fixes, build fixes, memory leak fixes, and other stability and reliability improvements

Binaries for Android, iOS, Mac OS X and Windows will be made available shortly at the usual location.
