Imagine I am using FFmpeg to read a raw YUV file. How do I flag that
input file as interlaced so that interlaced aware filters process the
stream correctly?
For instance:
I have an SD PAL sized yvyu422 file that I know is top-field-first
I want to output that as PAL DV 25, which is bottom-field-first
I expect to use a command like like this:
ffmpeg -f rawvideo -r 25 -s 720x576 -pix_fmt yuyv422 -i input.yvyu422
-vf fieldorder=bff -vcodec dvvideo -pix_fmt yuv420p -y output.mov
But, since the input file is not flagged as interlaced the fieldorder
filter cannot do it's job.
Thanks.
