From: "Saliev, Rafik F" <rafik.f.saliev-at-intel.com@ffmpeg.org> To: "ffmpeg-devel@ffmpeg.org" <ffmpeg-devel@ffmpeg.org> Subject: [FFmpeg-devel] [PATCH] libavfilter/dnn/dnn_backend_openvino.c: fix openvino async mode Date: Mon, 12 Dec 2022 10:31:01 +0000 Message-ID: <PH7PR11MB5887F1A68C19249217A6C09EDAE29@PH7PR11MB5887.namprd11.prod.outlook.com> (raw) Bugfix: The OpenVino DNN backend in the 'async' mode sets 'task->inference_done' to 'complete' prior to data copy from OpenVino output buffer to task's output frame. This order causes task destroy in ff_dnn_get_result_common() prior to model output processing.
