* dnn_backend_tf.c: add option sess_config for tf backendGuo, Yejun2020-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | TensorFlow C library accepts config for session options to set different parameters for the inference. This patch exports this interface. The config is a serialized tensorflow.ConfigProto proto, so we need two steps to use it: 1. generate the serialized proto with python (see script example below) the output looks like: 0xab...cd where 0xcd is the least significant byte and 0xab is the most significant byte. 2. pass the python script output into ffmpeg with dnn_processing=options=sess_config=0xab...cd The following script is an example to specify one GPU. If the system contains 3 GPU cards, the visible_device_list could be '0', '1', '2', '0,1' etc. '0' does not mean physical GPU card 0, we need to try and see. And we can also add more opitions here to generate more serialized proto. script example to generate serialized proto which specifies one GPU: import tensorflow as tf gpu_options = tf.GPUOptions(visible_device_list='0') config = tf.ConfigProto(gpu_options=gpu_options) s = config.SerializeToString() b = ''.join("%02x" % int(ord(b)) for b in s[::-1]) print('0x%s' % b)

| | | | | | | | ad73b32d2922f4237405043d19763229aee0e59e added some code for freeing in the input's config_props function, yet this is unnecessary as uninit is called anyway if config_props fails. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avfilter/vf_minterpolate: Fix left shift of negative valueAndreas Rheinhardt2020-10-09
| | | | | | | | | | | | This has happened when initializing the motion estimation context if width or height of the video was smaller than the block size used for motion estimation and if the motion interpolation mode indicates not to use motion estimation. The solution is of course to only initialize the motion estimation context if the interpolation mode uses motion estimation. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avfilter/vf_minterpolate: Reject too small dimensionsAndreas Rheinhardt2020-10-09
| | | | | | | | | | The latter code relies upon the dimensions to be not too small; otherwise one will call av_clip() with min > max lateron which aborts in case ASSERT_LEVEL is >= 2 or one will get a nonsense result that may lead to a heap-buffer-overflow/underflow. The latter has happened in ticket #8248 which this commit fixes. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* Revert "avfilter/setparams: add FF_FILTER_FLAG_HWFRAME_AWARE"Mark Thompson2020-09-29
| | | | | | | This reverts commit 5bbf58ab876279ca1a5a2f30563f271c99b93e62. The setparams filters are not hwframe aware, so the default context passthrough behaviour is needed to allow using them with hardware frames.

* dnn: add a new interface DNNModel.get_outputGuo, Yejun2020-09-21
| | | | | | | | | | for some cases (for example, super resolution), the DNN model changes the frame size which impacts the filter behavior, so the filter needs to know the out frame size at very beginning. Currently, the filter reuses DNNModule.execute_model to query the out frame size, it is not clear from interface perspective, so add a new explict interface DNNModel.get_output for such query.
* dnn: put DNNModel.set_input and DNNModule.execute_model togetherGuo, Yejun2020-09-21
| | | | | | | | | | | | | | suppose we have a detect and classify filter in the future, the detect filter generates some bounding boxes (BBox) as AVFrame sidedata, and the classify filter executes DNN model for each BBox. For each BBox, we need to crop the AVFrame, copy data to DNN model input and do the model execution. So we have to save the in_frame at DNNModel.set_input and use it at DNNModule.execute_model, such saving is not feasible when we support async execute_model. This patch sets the in_frame as execution_model parameter, and so all the information are put together within the same function for each inference. It also makes easy to support BBox async inference.
* dnn: change dnn interface to replace DNNData* with AVFrame*Guo, Yejun2020-09-21
| | | | | | | | | | | | Currently, every filter needs to provide code to transfer data from AVFrame* to model input (DNNData*), and also from model output (DNNData*) to AVFrame*. Actually, such transfer can be implemented within DNN module, and so filter can focus on its own business logic. DNN module also exports the function pointer pre_proc and post_proc in struct DNNModel, just in case that a filter has its special logic to transfer data between AVFrame* and DNNData*. The default implementation within DNN module is used if the filter does not set pre/post_proc.
