* avfilter/vf_sr.c: refine code to use AVPixFmtDescriptor.log2_chroma_h/wGuo, Yejun2020-03-03
| | | | | Signed-off-by: Guo, Yejun <yejun.guo@intel.com> Reviewed-by: Pedro Arthur <bygrandao@gmail.com>
* avfilter/vf_sr: correct flags since the filter changes frame w/hGuo, Yejun2019-10-30
| | | | | | | | If filter changes frame w/h, AVFILTER_FLAG_SUPPORT_TIMELINE_GENERIC cannot be supported. Signed-off-by: Guo, Yejun <yejun.guo@intel.com> Signed-off-by: Pedro Arthur <bygrandao@gmail.com>
* avfilter/dnn: get the data type of network output from dnn execution resultGuo, Yejun2019-10-30
| | | | | | | | | | | so, we can make a filter more general to accept different network models, by adding a data type convertion after getting data from network. After we add dt field into struct DNNData, it becomes the same as DNNInputData, so merge them with one struct: DNNData.

* lavf/sr: Refine the coding style for initJun Zhao2019-06-03

* lavf/sr: Don't need to check NULL before sws_freeContextJun Zhao2019-06-03

* lavfi/sr: Change the backend type from flags to intJun Zhao2019-05-28
| | | | | | | native and tensorflow is exclusive, so change the type from flags to int. Signed-off-by: Jun Zhao <barryjzhao@tencent.com>

* libavfilter/dnn: add more data type support for dnn model inputGuo, Yejun2019-05-08
| | | | | | | | currently, only float is supported as model input, actually, there are other data types, this patch adds uint8. Signed-off-by: Guo, Yejun <yejun.guo@intel.com> Signed-off-by: Pedro Arthur <bygrandao@gmail.com>
* libavfilter/dnn: support multiple outputs for tensorflow modelGuo, Yejun2019-05-08
| | | | | | | | | | | | some models such as ssd, yolo have more than one output. the clean up code in this patch is a little complex, it is because that set_input_output_tf could be called for many times together with ff_dnn_execute_model_tf, we have to clean resources for the case that the two interfaces are called interleaved.

* libavfilter/dnn: determine dnn output during execute_model instead of ↵Guo, Yejun2019-05-08
| | | | | | | | | | | | | | | | | | | set_input_output Currently, within interface set_input_output, the dims/memory of the tensorflow dnn model output is determined by executing the model with zero input, actually, the output dims might vary with different input data for networks such as object detection models faster-rcnn, ssd and yolo. This patch moves the logic from set_input_output to execute_model which is suitable for all the cases. Since interface changed, and so dnn_backend_native also changes. In vf_sr.c, it knows it's srcnn or espcn by executing the model with zero input, so execute_model has to be called in function config_props Signed-off-by: Guo, Yejun <yejun.guo@intel.com> Signed-off-by: Pedro Arthur <bygrandao@gmail.com>
* libavfilter/dnn: remove limit for the name of DNN model input/outputGuo, Yejun2019-05-08

* libavfilter/vf_sr: refine code to remove keyword 'else'Guo, Yejun2019-05-08
