08/09/2023, 5:46 PMWe are using the gstreamer libvpx binding for encoding. I couldn't find any confirmation of whether vp8enc supports multithreading, but it does look like it may not, considering that there is an option in libvpx enable multithreading for vp9, but not vp8

08/09/2023, 5:47 PMWhat resolution are you encoding, on what kind of core? There are tweaks to adjust the cpu usage/quality tradeoff for vp8 encoding, They are set to the default values currently
chilly-animal-65189
08/09/2023, 5:58 PMWell, never mind: https://www.webmproject.org/docs/encoder-parameters/ item 6.

08/09/2023, 6:08 PMStill curious about your use case to understand a bit better what to set this to. It looks like there are some restrictions linked to frame size

08/09/2023, 6:08 PMFor the moment, I test from 1080p to 480p, with quality from 0 to 2, and bitrate from 10kB/s to 500kB/s, nothing change, still 100% of one core and latency which increase
happy-ability-28669
08/09/2023, 6:10 PMFor the moment, we need vp8 because the python client sdk (based on the rust one) only support vp8.

08/09/2023, 6:12 PMWhat is the cpu core this runs on?
chilly-animal-65189
08/09/2023, 6:13 PMif we can't keep up on 1 core at 480p, multithreading is unlikely to be enough for 1080p

08/09/2023, 6:18 PMI will try tomorrow on your cloud ingress to see if it’s my livekit setup or the server which cause the behavior

08/09/2023, 6:21 PMI have no doubt cloud will also fail at 1080p without multihreading. 480p is more interesting

08/10/2023, 5:21 AM@happy-ability-28669 We have not optimized Ingress for VP8 encoding yet. This is on our roadmap. Once completed it should have no issues utilizing multiple cores.

08/10/2023, 8:12 AMAny idea when the rust client will support the h264 ?
