* vf_dnn_processing: add support for more formats gray8 and grayf32Guo, Yejun2020-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following is a python script to halve the value of the gray image. 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 from skimage import color from skimage import io in_img = io.imread('input.jpg') in_img = color.rgb2gray(in_img) io.imsave('ori_gray.jpg', np.squeeze(in_img)) in_data = np.expand_dims(in_img, axis=0) in_data = np.expand_dims(in_data, axis=3) filter_data = np.array([0.5]).reshape(1,1,1,1).astype(np.float32) filter = tf.Variable(filter_data) x = tf.placeholder(tf.float32, shape=[1, None, None, 1], 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()) graph_def = tf.graph_util.convert_variables_to_constants(sess, sess.graph_def, ['dnn_out']) tf.train.write_graph(graph_def, '.', 'halve_gray_float.pb', as_text=False) print("halve_gray_float.pb generated, please use \ path_to_ffmpeg/tools/python/convert.py to generate halve_gray_float.model\n") output = sess.run(y, feed_dict={x: in_data}) output = output * 255.0 output = output.astype(np.uint8) io.imsave("out.jpg", np.squeeze(output)) To do the same thing with ffmpeg: - generate halve_gray_float.pb with the above script - generate halve_gray_float.model with tools/python/convert.py - try with following commands ./ffmpeg -i input.jpg -vf format=grayf32,dnn_processing=model=halve_gray_float.model:input=dnn_in:output=dnn_out:dnn_backend=native out.native.png ./ffmpeg -i input.jpg -vf format=grayf32,dnn_processing=model=halve_gray_float.pb:input=dnn_in:output=dnn_out:dnn_backend=tensorflow out.tf.png Signed-off-by: Guo, Yejun <yejun.guo@intel.com> Signed-off-by: Pedro Arthur <bygrandao@gmail.com>

| | | | | | | | | | | | do not request AVFrame's format in vf_ddn_processing with 'fmt', but to add another filter for the format. command examples: ./ffmpeg -i input.jpg -vf format=bgr24,dnn_processing=model=halve_first_channel.model:input=dnn_in:output=dnn_out:dnn_backend=native -y out.native.png ./ffmpeg -i input.jpg -vf format=rgb24,dnn_processing=model=halve_first_channel.model:input=dnn_in:output=dnn_out:dnn_backend=native -y out.native.png Signed-off-by: Guo, Yejun <yejun.guo@intel.com> Signed-off-by: Pedro Arthur <bygrandao@gmail.com>

* avformat/mpegtsenc: allow any sensible PID for elementary and PMT PIDsMarton Balint2019-12-03
| | | | | | | | | | | | | This sets the range of the first automatically assigned PMT PID or elementary stream PID parameters to [0x20, 0x1ffa]. You can still assign manually a PID for a stream using AVStream->id in the wider [0x10, 0x1ffe] range as specified by ISO13818-1. But since DVB and ATSC both reserves some PIDs, let's not allow them to be automatically assigned. Also make sure that assigned PID numbers are valid and fix the error message for the previous PID collision checks. Signed-off-by: Marton Balint <cus@passwd.hu>
