#6562: FFmpeg's ass filter draw wrong shapes -------------------------------------+---------------------------------- Reporter: greatrobert | Type: defect Status: new | Priority: normal Component: ffmpeg | Version: Keywords: libass | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+---------------------------------- I have an ass file with some specific shapes, when I use command line <ffmpeg.exe -v 9 -loglevel 99 -i "D:\test\1.mp4" -vf "ass=D\\:test/1.ass" -f mp4 -y "D:\test\ffmpeg.mp4"> to burn it into video file, the shapes are in a mess. But when I use FFmpeg+AvisynthPlus (command line <ffmpeg.exe -i "D:\test\1.avs" -f mp4 -y "D:\test\ffmpeg+AvisynthPlus.mp4">) to burn it, the shapes are exact. All the files and logs are attached.
