PipeWire 0.3.77 (2023-08-04)
This is a quick bugfix release that is API and ABI compatible with previous 0.3.x releases.
Highlights
- Fix a bug in ALSA source where the available number of samples was miscaluclated and resulted in xruns in some cases.
- A new L permission was added to make it possible to force a link between nodes even when the nodes can’t see each other.
- The VBAN module now supports midi send and receive as well.
- Many cleanups and small fixes.
True, and it’s fabulous for video as well.
Ow you are right. I wasn’t aware of the video part of Pipewire. Which allows very low latency video recording as well.
Fun fact: with the proper plugins, you can capture both the video and the output of a particular window / process in OBS, giving you a stream of exactly that and nothing else (which you can then mix with other sources). Very handy for streaming if you don’t want to include voice chat (for privacy reasons) or background music (DMCA takedown on VODs).
However, for capturing Vulkan games, I recommend the vkcapture plugin. It acts as a Vulkan layer and is very performant, plus I get the impression it works better with Freesync.
I hate OBS under Linux still doesn’t allow me to use the GPU (using AMD videocard) for encoding.
Don’t blame OBS, AMD’s video encoding is awful in a multitude of ways
owh…? I was hoping it was open-source. Some standard API. or something…
As someone said, there are ways to get it working in OBS.
Does it expose the full feature set using VA-API? I have no clue. I was never able to actually hit the bitrate I wanted.
Please note that cards until the RX 6000 generation do not support B-frames.
AMD’s encoders are garbage, but if you insist, you can use VA-API to get accelerated encoding in the output advanced settings.
