_EncodedFrameTop / Bottom maybe wrong?

[MIRIMIRIM]

I have such a clip

Source Frame	0		1			2		3
TFF flag	1		1			0		0
RFF flag	0		1			0		1
Field	0t	0b	1t	1b	1t_r	2b	2t	3b	3t	3b_r
Decode Frame	0		1		2		3		4

Top three columns are from clip headers, field column is the result I think we should get. “_r” means repeat.

_EncodedFrameTop [int], _EncodedFrameBottom [int]
Frame number (before pulldown) used to generate this frame's top/bottom field.

But I got the following props when use LWLibavVideoSource(clip, repeat=True):

frame	_EncodedFrameTop	_EncodedFrameBottom
0	0	0
1	1	1
2	2	2
3	2	3
4	3	4

I’m not sure what went wrong.

Can you share a short sample?

I use mmg trim the first few frames from the original DVD source

Thanks.

Try the attached test version.

Use ffprobe -show_frames sample.mkv to get the frames metadata.

Thank you for the fix, at the same time I realized that I was looking at the wrong order of frames and have fixed the issue description.
