Wrong frame rate problem

[MunMunMiao]

First, I used staxrip and identified the problem caused by ffms2

When V2.2

1、The frame rate is 58.407803 FPS, not 29.97 FPS.
2、The video rendered with this configuration. There will be acceleration problems at 00:00:08

this's output file mega

When V2.4

In this version, although the frame rate resolution is correct. But at 00:00:03, 00:00:08, there will be jitter.

I'll take a look, I suspect the the problem (or maybe it 'fixed' the file) is related to interlacing fixes.

StaxRip, MeGUI, XviD4PSP5, AviSynth, FFMS2 and other Windows tools are not suitable for encoding arbitrary files due to the lack of support for non-linear container timecodes and variable frame rates. They are defective in design (CFR only). Use these tools for DVD/BluRay encoding only. For everything else, there is Handbrake (ffmpeg based) or Avidemux at least.

Older decoders incorrectly define fps as 2x. In addition, ffmpeg reports that there are some "corrupt decoded frames", but that's okay. Handbrake and Avidemux encode fine (at 29.97p). The problem is with ffms2 and avisynth (video slowdown), I confirm.
