On January 23, a message appeared on the github page of the Open Broadcaster Software project about the completion of work to support AV1 video encoding using the Linux Video Acceleration API (VA-API). On May 2, 2023, a merge request was opened for the OBS FFmpeg code to add AV1 VA-API support, and as of the evening of January 23, the code has been merged.
The code has been successfully tested with VA-API AV1 encoding using Mesa drivers, which is available for AMD Radeon RX 7000 series and Intel Arc Graphics series video cards (if we are talking about video cards that support the open source Mesa driver). Unfortunately, merging this code took a long time, but the next release of OBS will include this feature.
For reference: Open Broadcaster Software (or OBS for short) is a free, open-source video recording and streaming program developed by the OBS project and a community of independent developers, the project itself is written in C and C++.
OBS provides the ability to capture video streams from devices and sources in real time, scene composition, decoding, recording and broadcasting. For example, OBS together with an IP camera can be used for video surveillance. Data transmission is carried out mainly through the Real Time Messaging Protocol (RTMP).
