From: "Chen, Angus" <angus.c...@intel.com>
sdl2_muxer(wayland):
In ffmpeg6, we create a separate thread for muxer after calling
avformat_write_header().
It may generate EGL_BAD_ACCESS when we call write_packet. This is because
egl_context
is bound to previous thread.
>From EGL spec: If ctx is current to some other thread, or if either draw or
>read are
bound to contexts in another thread, an EGL_BAD_ACCESS error is generated.
