Summary of the bug:
When using a real 1080p60 video source (i.e. not lavfi), attempting to
both crop to 1440x1080 and then interlace causes FFMPEG to crash. The same
video can be either cropped or interlaced individually with success. Also,
doing the cropping and interlacing in two subsequent encodes works as
expected. Interestingly, if I crop, scale to 720x480, then interlace in a
single encode, this works as expected.
How to reproduce:
Use included sample (or perhaps another 1080p60 video) and then use the
following command line:
{{{
% ffmpeg -i 1080p60sample.mp4 -vf crop=1440:1080,interlace=scan=tff -c:v
libx264 -x264-params tff -flags +ilme+ildct -an output.mp4
}}}
