If a progressive 25 frames video is encoded as 50 interlaced fields, you should after decoding with FFmpeg get your original 25 frames: FFmpeg does not know fields internally, only frames. Real interlaced material can of course not be deinterlaced without degrading quality (compared to the original progressive material): The information is lost.
