Validate if the meta returned by gst_buffer_get_vaapi_video_meta() in
the acquired buffer is not null.
This situation should be very "pathological", but still it is better
be safe since that meta might be used later to create a new dma
buffer.
/* Update the underlying surface proxy */
meta = gst_buffer_get_vaapi_video_meta (buffer);
- if (meta)
- gst_vaapi_video_meta_set_surface_proxy (meta, priv_params->proxy);
+ if (!meta) {
+ *out_buffer_ptr = buffer;
+ return GST_FLOW_ERROR;
+ }
+ gst_vaapi_video_meta_set_surface_proxy (meta, priv_params->proxy);
/* Find the cached memory associated with the given surface. */
surface = GST_VAAPI_SURFACE_PROXY_SURFACE (priv_params->proxy);
