2020-01-05doc/volume: correct placement of replaygain_noclipGyan Doshi
In the merge commit 878f8b0d26, entry for replaygain_noclip was placed in commands, which it is not, instead of among the options.

2019-12-17avfilter: Add tonemap vaapi filter for H2SXinpeng Sun
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>

2019-12-08avfilter/scale.c: factorize ff_scale_eval_dimensionsGyan Doshi
Adjustment of evaluated values shifted to ff_adjust_scale_dimensions Shifted code for force_original_aspect_ratio and force_divisble_by from vf_scale so it is now available for scale_cuda, scale_npp and scale_vaapi as well.

2019-11-07avfilter/vf_dnn_processing: add a generic filter for image proccessing with ↵Guo, Yejun
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>
