When using the webcam on Google Meet with QtWebEngine 5.15.3, I can see myself, but other users don't see my picture at all. The following is logged:
[395085:30:0406/171000.208940:ERROR:vp9_impl.cc(744)] Init error: ABI version mismatch [395085:30:0406/171000.209126:ERROR:video_stream_encoder.cc(798)] Failed to initialize the encoder associated with codec type: VP9 (2) [395085:30:0406/171000.209202:ERROR:video_stream_encoder.cc(829)] Failed to configure encoder.

With a developer build of the current 5.15 branch, I instead get a malloc error and renderer process crash:

With 5.15.2, things seem to work fine.
