[FFmpeg-user] Interlaced x264

[Anatol]

Hi,
I am looking for a way to create interlaced x264 TFF file.
The media info result that I get is

Scan type                                : MBAFF

The scan order is not mentioned.
The '-vf idet' check of the resultant file is considerably different
compared to an interlaced PAFF file.

Command line:

ffmpeg -threads 1 -i
/web//content/r71v1/entry/data/551/98/1_jpzy9xr0_1_t3mdjl8h_11.mp4 -c:v
libx264  -subq 7 -qcomp 0.6 -qmin 10 -qmax 50 -qdiff 4 -bf 16 -coder 1
-refs 6 -x264opts
b-pyramid:weightb:mixed-refs:8x8dct:no-fast-pskip=0:interlaced=1:tff=1:weightp=0
-vprofile high -force_key_frames expr:'gte(t,n_forced*2)' -pix_fmt yuv420p
-b:v 4000k -s 720x480 -r 29.97 -g 60 -aspect 720:480 -c:a libfdk_aac -b:a

-sc_threshold 40 -i_qfactor 0.71 -bt 1200k -maxrate 4000k -bufsize 8000k
-rc_eq 'blurCplx^(1-qComp)' -aspect 4:3 -top 1 -flags +ilme+ildct  -vsync 1
-threads 4  -y BBB_30sec_interlaced.ts

Uncut console output - in the attached file.

Thanks in advance,
Anatol
