I’m trying to use the cropdetect filter on some JPEG images, but it’s not showing anything useful in the console output. I checked to see if it’s available with “ffplay -filters” and that shows the following line: T.. cropdetect V->V Auto-detect crop size.
Example command: $ ffplay -i A002C001_140919_R6OW.000072.jpg -vf "cropdetect=24:16:0" ffplay version 2.3.git-9b8eedd Copyright (c) 2003-2014 the FFmpeg developers built on Sep 19 2014 00:12:16 with Apple LLVM version 6.0 (clang-600.0.51) (based on LLVM 3.5svn) configuration: --prefix=/opt/local --enable-swscale --enable-avfilter --enable-avresample --enable-libmp3lame --enable-libvorbis --enable-libopus --enable-libtheora --enable-libschroedinger --enable-libopenjpeg --enable-libmodplug --enable-libvpx --enable-libspeex --enable-libass --enable-libbluray --enable-gnutls --enable-fontconfig --enable-libfreetype --enable-libfribidi --disable-indev=jack --disable-outdev=xv --mandir=/opt/local/share/man --enable-shared --enable-pthreads --cc=/usr/bin/clang --enable-vda --arch=x86_64 --enable-yasm --enable-gpl --enable-postproc --enable-libx264 --enable-libxvid --enable-nonfree --enable-libfdk-aac --enable-libfaac libavutil 54. 7.100 / 54. 7.100 libavcodec 56. 1.100 / 56. 1.100 libavformat 56. 3.100 / 56. 3.100 libavdevice 56. 0.100 / 56. 0.100 libavfilter 5. 0.103 / 5. 0.103 libavresample 2. 1. 0 / 2. 1. 0 libswscale 3. 0.100 / 3. 0.100 libswresample 1. 1.100 / 1. 1.100 libpostproc 53. 0.100 / 53. 0.100 Input #0, image2, from 'A002C001_140919_R6OW.000072.jpg':0B f=0/0 Duration: 00:00:00.04, start: 0.000000, bitrate: N/A Stream #0:0: Video: mjpeg, yuvj420p(pc, bt470bg), 512x288 [SAR 144:144 DAR 16:9], 25 tbr, 25 tbn, 25 tbc [swscaler @ 0x7fdd3480c600] deprecated pixel format used, make sure you did set range correctly 1.98 M-V: 0.000 fd= 0 aq= 0KB vq= 0KB sq= 0B f=0/0 _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
