Lynne	907ae87d6e	lavfi: add an chromaber_vulkan filter This commit adds a chromatic aberration filter for Vulkan that attempts to emulate a lens chromatic aberration effect. For a YUV frame it will instead shift the chroma channels, providing a simple approximation.	5 years ago
Lynne	a2db7343e0	lavfi: add an avgblur_vulkan filter This commit adds a fast avgblur Vulkan filter. This will reset Intel GPUs on Linux due to a known, two-year-old driver bug (!834 on mesa's gitlab).	5 years ago

Xinpeng Sun	2e2dfe6673	avfilter: Add tonemap vaapi filter for H2S It performs HDR(High Dynamic Range) to SDR(Standard Dynamic Range) conversion with tone-mapping. It only supports HDR10 as input temporarily. An example command to use this filter with vaapi codecs: FFMPEG -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -hwaccel_output_format vaapi \ -i INPUT -vf 'tonemap_vaapi=format=p010' -c:v hevc_vaapi -profile 2 OUTPUT Signed-off-by: Xinpeng Sun <xinpeng.sun@intel.com> Signed-off-by: Zachary Zhou <zachary.zhou@intel.com> Signed-off-by: Ruiling Song <ruiling.song@intel.com>	5 years ago

Guo, Yejun	4d980a8ceb	avfilter/vf_dnn_processing: add a generic filter for image proccessing with dnn networks This filter accepts all the dnn networks which do image processing. Currently, frame with formats rgb24 and bgr24 are supported. Other formats such as gray and YUV will be supported next. The dnn network can accept data in float32 or uint8 format. And the dnn network can change frame size. The following is a python script to halve the value of the first channel of the pixel. It demos how to setup and execute dnn model with python+tensorflow. It also generates .pb file which will be used by ffmpeg. import tensorflow as tf import numpy as np import imageio in_img = imageio.imread('in.bmp') in_img = in_img.astype(np.float32)/255.0 in_data = in_img[np.newaxis, :] filter_data = np.array([0.5, 0, 0, 0, 1., 0, 0, 0, 1.]).reshape(1,1,3,3).astype(np.float32) filter = tf.Variable(filter_data) x = tf.placeholder(tf.float32, shape=[1, None, None, 3], name='dnn_in') y = tf.nn.conv2d(x, filter, strides=[1, 1, 1, 1], padding='VALID', name='dnn_out') sess=tf.Session() sess.run(tf.global_variables_initializer()) output = sess.run(y, feed_dict={x: in_data}) graph_def = tf.graph_util.convert_variables_to_constants(sess, sess.graph_def, ['dnn_out']) tf.train.write_graph(graph_def, '.', 'halve_first_channel.pb', as_text=False) output = output * 255.0 output = output.astype(np.uint8) imageio.imsave("out.bmp", np.squeeze(output)) To do the same thing with ffmpeg: - generate halve_first_channel.pb with the above script - generate halve_first_channel.model with tools/python/convert.py - try with following commands ./ffmpeg -i input.jpg -vf dnn_processing=model=halve_first_channel.model:input=dnn_in:output=dnn_out:fmt=rgb24:dnn_backend=native -y out.native.png ./ffmpeg -i input.jpg -vf dnn_processing=model=halve_first_channel.pb:input=dnn_in:output=dnn_out:fmt=rgb24:dnn_backend=tensorflow -y out.tf.png Signed-off-by: Guo, Yejun <yejun.guo@intel.com> Signed-off-by: Pedro Arthur <bygrandao@gmail.com>	5 years ago
