[Cin] 10bit VAAPI encoding test thread

We branching! I looked at gpu-screen-recorder https://git.dec05eba.com/gpu-screen-recorder/tree/src/encoder/video/vaapi.c it sets AVHWFramesContext *hw_frame_context = (AVHWFramesContext*)frame_context->data; hw_frame_context->width = video_codec_context->width; hw_frame_context->height = video_codec_context->height; hw_frame_context->sw_format = self->params.color_depth == GSR_COLOR_DEPTH_10_BITS ? AV_PIX_FMT_P010LE : AV_PIX_FMT_NV12; hw_frame_context->format = video_codec_context->pix_fmt; hw_frame_context->device_ctx = (AVHWDeviceContext*)self->device_ctx->data; so may be we need to set AV_PIX_FMT_P010LE and not just P010?
