#3246: Provide means to hide configuration, libraries, copyright information, build info but retain input and progress info -------------------------------------+------------------------------------- Reporter: qubodup | Type: Status: new | enhancement Component: | Priority: normal undetermined | Version: Keywords: | unspecified Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- I use ffmpeg directly in the command line. When debugging, the progress report information is very useful but the block of information about copyright, build, configuration and library version info is redundant and disturbs the formatting of the visible text in the terminal. I always have trouble finding the output of a previous command when for example using ffmpeg in a shell script together with other commands. {{{ ffmpeg version 2.1.1 Copyright (c) 2000-2013 the FFmpeg developers built on Dec 10 2013 06:36:11 with gcc 4.8.2 (GCC) configuration: --prefix=/usr --disable-debug --disable-static --enable- avresample --enable-dxva2 --enable-fontconfig --enable-gnutls --enable-gpl --enable-libass --enable-libbluray --enable-libfreetype --enable-libgsm --enable-libmodplug --enable-libmp3lame --enable-libopencore_amrnb --enable-libopencore_amrwb --enable-libopenjpeg --enable-libopus --enable- libpulse --enable-librtmp --enable-libschroedinger --enable-libspeex --enable-libtheora --enable-libv4l2 --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-pic --enable-postproc --enable- runtime-cpudetect --enable-shared --enable-swresample --enable-vdpau --enable-version3 --enable-x11grab libavutil 52. 48.101 / 52. 48.101 libavcodec 55. 39.101 / 55. 39.101 libavformat 55. 19.104 / 55. 19.104 libavdevice 55. 5.100 / 55. 5.100 libavfilter 3. 90.100 / 3. 90.100 libavresample 1. 1. 0 / 1. 1. 0 libswscale 2. 5.101 / 2. 5.101 libswresample 0. 17.104 / 0. 17.104 libpostproc 52. 3.100 / 52. 3.100 }}} `-loglevel quiet` hides all of the mentioned above.
