Hi,
when I am trying to execute following transcode I receive segmentation
fault.
( I am trying to rotate initial video and then scale it down, adding two
equal vertical black stripes on the left and right).
What is most peculiar is that if I change pad to pad=152,270,0,0 this
segfault does not happen.
Please find ffmpeg output below:
ffmpeg -v 9 -loglevel 99 -i rotation_-90.MOV -vcodec libx264 -r 20 -b 768k
-bt 768k -vf transpose=3,scale=152:270,pad=480:270:164:0 -s 480x270 -an
-preset medium -fastfirstpass 1 -profile baseline -pass 1 -passlogfile
result.mp4.passlogfile -f rawvideo -y /dev/null
