[FFmpeg-user] Showinfo bug?

[Mark Filipak]

Is this a showinfo bug, or am I misinterpreting the results?

For VOBs that are known to be 23.976 FPS, soft-telecined, this command:
'ffprobe -f lavfi movie=VTS_01_1.VOB,showinfo'
reports that they're 59.94 FPS.

The first & last lines of output show this:
"[Parsed_showinfo_1 @ 000001d381f6dc80] config in time_base: 1/90000, 
frame_rate: 60000/1001"
"    Stream #0:0: Video: rawvideo (I420 / 0x30323449), yuv420p, 720x480 
[SAR 1:1 DAR 3:2], 59.94 tbr, 90k tbn, 90k tbc"

This seems to be a rather big error, if indeed it is an error. At 
question is the reliability of ff*.

In contrast, as expected, 29.97 FPS, hard-telecined videos are reported 
as 29.97 FPS.
"[Parsed_showinfo_1 @ 00000222eeb2dc80] config in time_base: 1/90000, 
frame_rate: 30000/1001"
"    Stream #0:0: Video: rawvideo (I420 / 0x30323449), yuv420p, 720x480 
[SAR 1:1 DAR 3:2], 29.97 fps, 29.97 tbr, 90k tbn, 90k tbc".

Please comment. I'm not particularly knowledgeable regarding ff*.

Regards,
Mark.
