FFmpeg, x264: "Interlace + weightp is not implemented"

[peter_b]

Encoding interlaced source to H.264 (libx264):

Code: Select all

$ ffmpeg -i VIDEO_IN -c:a copy -c:v libx264 -preset slow -crf 23 -flags +ildct+ilme VIDEO_OUT.avi

Works, but there's a warning of some sort:

[libx264 @ 0x4143540] interlace + weightp is not implemented

Seems like this is just saying that some optimizations (like weightp, for example) have no effect when encoding interlaced.
Okay.
