Disabling H264 Hardware acceleration #547
Description
Hello,
I want to disable GPU hardware acceleration for H.264 encoding and force WebRTC to use CPU-based encoding instead.
Right now, WebRTC fails to encode the H.264 video frames and logs the following error:
ai-avatar INFO:__main__:Avatar stdout:
2025-12-14 14:02:36,064 - DEBUG livekit - libwebrtc:50:libwebrtc::imp::peer_connection_factory - (video_stream_encoder.cc:2108): Failed to encode frame. Error code: -7
It appears this WebRTC error prevents the encoder from initializing properly when H.264 hardware acceleration is enabled.
when I prevent the code from seeing the gpu it works fine, but I want the gpu for other part of the code not livekit encoding.
