[Ffmpeg-devel] dv ntsc 640x480 sqare pixels probed as 720x480

[Marcus Engene]

Hi,

If I export a clip in Premiere 1.5 as
DV/DVCPRO - NTSC
640x480
Square pixels

ffmpeg probes this as 720x480
Why does it do that? Is there any way to tell is something is square 
pixels instead of 0.9?
Quicktime player reports the clip to be 640x480

example:

Best regards,
Marcus
