Hi I want to extract closed captions from an mpegts stream coming through udp. I am using the following fommand line:
ffmpeg -f lavfi -i "movie=filename=udp\\://224.2.2.37\\:1051[out+subcc]" -map 0:1 output.srt But its not working. It gives the following output: ffmpeg version 3.2 Copyright (c) 2000-2016 the FFmpeg developers built with gcc 4.8 (Ubuntu 4.8.4-2ubuntu1~14.04.3) configuration: --disable-static --enable-shared --prefix=/home/tempbn741/source-2/install/ --enable-nonfree --extra-cflags=-I/home/tempbn741/source-2/install/include --extra-cxxflags= -I/home/tempbn741/source-2/install/include --extra-ldflags=-L/home/ tempbn741/source-2/install/lib --enable-libx264 --enable-libx265 --enable-libmp3lame --enable-gpl --extra-libs=-ldl --enable-openssl libavutil 55. 34.100 / 55. 34.100 libavcodec 57. 64.100 / 57. 64.100 libavformat 57. 56.100 / 57. 56.100 libavdevice 57. 1.100 / 57. 1.100 libavfilter 6. 65.100 / 6. 65.100 libswscale 4. 2.100 / 4. 2.100 libswresample 2. 3.100 / 2. 3.100 libpostproc 54. 1.100 / 54. 1.100 [Parsed_movie_0 @ 0x21d9180] Failed to avformat_open_input 'udp' [lavfi @ 0x21d7380] Error initializing filter 'movie' with args 'filename=udp://224.2.2.37:1051' movie=filename=udp\://224.2.2.37\:1051[out+subcc]: No such file or directory I have tried different options escaping the input string but none seems to work.
