[FFmpeg-user] Interlaced h264_vaapi?

I'm looking to get interlaced output from the h264_vaapi encoder, so far
without success. The equivalent command produces interlaced output from
libx264. h264_vaapi is reporting that it's producing interlaced output,
but mediainfo and ffmpeg always say progressive. Is it possible ?
The source is interlaced 1080i TV.
I can't find the meaning of "Invalid RefPicListX[] entry" on log output
or its significance, it's always output. This is using the i965 Intel
driver on an Ivy Bridge CPU.
I have tried adding '-field_order tt', which changes log output with
x264, but doesn't make output interlaced in either case. +ildct appears
to be the trigger to get x264 to produce interlaced output, but perhaps
no effect on vaapi ?
