The previous calculation used the video size in pixels, which might lead
to stretched/squashed videos in rare cases where the video has non-square
pixels. The new calculation is correct for all video sizes.

The video_info function returns the start time already in milliseconds,
so compare against 1ms instead of 1/1000.

The ffprobe command in ffmpeg 4.0 now omits the aspect ratio fields in the
json output when indeterminate, instead of returning an invalid value with
0 in the numerator or denominator. Handle this correctly.
