Generate Telecine Sequence

[ht techdev]

Hi 

Using gstreamer 1.4.5, I am trying to generate a telecine sequence, and used
the following pipeline:

gst-launch-1.0 -v -m videotestsrc is-live=true pattern=zone-plate kx2=20
ky2=20 kxy=4 kt2=10 num-buffers=50 ! video/x-raw,
format=I420,width=1920,height=1080,framerate=24/1,interlace-mode=progressive
! interlace field-pattern=2 allow-rff=true ! x264enc bitrate=6000
byte-stream=true interlaced=true ! h264parse! mpegtsmux ! filesink
location=2_3_telecin.ts

However, analyzing the resultant clip, with ffprobe, indicates that there is
no field repetition, and duration of all generated frames is the same.

Any thoughts?

Cheers,
