Windows Command Prompt doesn't handle splits with floating point numbers, PowerShell does. silence_end: 15.6667 | silence_duration: 5.This is where we need PowerShell. silence_start: 0.49 bitrate=N/A speed=12.8x Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '/Users/user/Desktop/SilenceTopTail.mov': Silent at the Begging and End of File (Two sections of silence, but not entirely silent) ffmpeg version 4.4.1 Copyright (c) 2000-2021 the FFmpeg developers Video:246kB audio:2938kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown Here are two possible examples that contain silence:Įntirely Silent File ffmpeg version 4.4.1 Copyright (c) 2000-2021 the FFmpeg developersīuilt with Apple clang version 12.0.0 (clang-1200.0.32.29)Ĭonfiguration: -prefix=/usr/local/Cellar/ffmpeg/4.4.1_3 -enable-shared -enable-pthreads -enable-version3 -cc=clang -host-cflags= -host-ldflags= -enable-ffplay -enable-gnutls -enable-gpl -enable-libaom -enable-libbluray -enable-libdav1d -enable-libmp3lame -enable-libopus -enable-librav1e -enable-librist -enable-librubberband -enable-libsnappy -enable-libsrt -enable-libtesseract -enable-libtheora -enable-libvidstab -enable-libvmaf -enable-libvorbis -enable-libvpx -enable-libwebp -enable-libx264 -enable-libx265 -enable-libxml2 -enable-libxvid -enable-lzma -enable-libfontconfig -enable-libfreetype -enable-frei0r -enable-libass -enable-libopencore-amrnb -enable-libopencore-amrwb -enable-libopenjpeg -enable-libspeex -enable-libsoxr -enable-libzmq -enable-libzimg -disable-libjack -disable-indev=jack -enable-avresample -enable-videotoolbox
#Ffmpeg command line quiet how to#
I'm not sure how to parse the output in order to do this and any nudges in the right direction would be extremely helpful - Thanks! There seems to be different rounding of decimal points depending on the values for FFMPEG's output (duration = 15.67, silence_duration=15.6667), so whatever accuracy is possible given these circumstances is ok. I think I would need to check if the last silence_duration value is equal to the duration. I am able to output the silence information via: ffmpeg -i FILE.mov -af silencedetect=noise=0.0001 -f null - 2>&1 I am trying to pass audio and video files into FFMPEG and determine if their audio is entirely silent (I don't need to detect if the audio stream is present or not, just if it is silent), and ideally return a boolean at the end of it all, or a 0/1.
