A Rust plugin delivery is ensured as part of the official binary packages for Windows and macOS platforms (builds and delivery are supported for Linux, Windows, and macOS).\n
A Rust-based media server using WebRTC has been implemented, supporting WHIP (WebRTC HTTP ingest) and WHEP (WebRTC HTTP egress).\n
The videocolorscale element has been added, combining capabilities for video conversion and scaling.\n
Improved support for high color depth video.\n
The Navigation API has added support for events from touch screens.\n
H.264\/H.265 timestamp correction elements have been added for reconstructing PTS\/DTS before the packaging of media containers.\n
On the Linux platform, DMA application has been improved for collaboration with buffers during encoding, decoding, filtering, and rendering of video using hardware acceleration.\n
CUDA integration has been enhanced: the gst-cuda library and cudaconvertscale element have been added, ensuring integration with D3D11 elements and NVIDIA dGPU NVMM.\n
Direct3D11 integration has been improved: the new gst-d3d11 library has been added, and the capabilities of the d3d11screencapture, d3d11videosink, d3d11convert, and d3d11compositor plugins have been expanded.\n
New hardware-accelerated video encoders in formats H.264\/AVC, H.265\/HEVC, and AV1 have been implemented for AMD GPUs, built using the AMF (Advanced Media Framework) SDK.\n
Support for encoding and decoding H.265\/HEVC video has been added to the applemedia plugin.\n
Support for encoding H.265\/HEVC video has been added to the androidmedia plugin.\n
The force-live property has been added to the audiomixer, compositor, glvideomixer, and d3d11compositor plugins to enforce live mode. <\/ul>\n
