Reported by: mulvya Owned by:
Priority: important Component: avfilter
Version: git-master Keywords: drawtext crash SIGSEGV
Cc: Blocked By:
Blocking: Reproduced by developer: yes
Analyzed by developer: no

Description

Use of command below causes ffmpeg to crash. Use of same command without borderw results in successful completion. Use of same command with borderw but with cour.ttf (Courier) results in successful completion.

Using 2016-03-17 Zeranoe build on Windows 7 Ultimate 64-bit (no SP installed). Behaviour reproduced on another system with same OS and set of font files.

Command:

ffmpeg -f lavfi -i "color=black:s=1280x720" -filter_complex "drawtext=fontfile=bpmono.ttf:text='Hello World':fontcolor=white@1.0:fontsize=16:borderw=5:x=w-tw-10:y=10:box=1:boxcolor=black@0.5" -c:v libx264 -preset veryfast -t 5 textwithborder.mp4 -report
