A revolution in game streaming starts now
The time has finally come, AV1 streaming is now available with OBS Studio software.
The AV1 and HEVC native streaming is now available on YouTube. This functionality has been added to the 29.1 version of OBS Studio which utilizes YouTube RTMP protocol that accepts AV1/HEVC video streams. Unfortunately, this does not mean that the video will be served in the same codec to end users, but at least streaming will now be possible at higher quality at the same bandwidth.
The development team has just released the first BETA of OBS Studio 29.1 with a long list of new features and fixes. This version introduces the new AV1 encoding support but requires proper hardware, such as GeForce RTX 40, Intel Arc or AMD Radeon 7000 series.
It is worth noting that AV1 recording was already possible through OBS Studio, but the new feature extends codec support to streaming. This is mainly because most platforms did not support this codec until now, but it has now been added to Discord and YouTube.
If you want to learn more about AV1 encoding and how it impacts streaming quality, check this guide by EposVox. He explains the best settings for different resolutions and how to utilize the new OBS feature properly. Just bear in mind the video is sponsored by Intel Arc.
