Question

我正在编写将短片合并到视频中的脚本，但是这些视频包含不同的大小和帧频。当我运行下面的代码时，输出的视频充满了第二个剪辑的毛刺。

from moviepy.editor import *

clips = [ VideoFileClip("clips/clip-1.mp4"),
VideoFileClip("clips/clip-2.mp4"),
VideoFileClip("clips/clip-3.mp4")]

final_clip = concatenate_videoclips(clips)
final_clip.write_videofile("final.mp4")`

搜索更好，我认为这可能是因为它们的属性不同，所以我包含了compose（）方法：

final_clip = concatenate_videoclips(clips, method='compose')

并出现以下错误：

我认为这是moviepy中的一个开放错误，请尝试安装1.0.0版

public class SrcParent
{
    public int Id { get; set; }
    public List<SrcChild> SrcChildren { get; set; }
}

public class SrcChild
{
    public int Id { get; set; }
    public int SrcParentId { get; set; }
    public string Name { get; set; }
    public string Value { get; set; }
}

public class DstParent
{
    public int Id { get; set; }
    public int ConfigurationId { get; set; }
    public List<DstChild> DstChildren { get; set; }
}

public class DstChild
{
    public int Id { get; set; }
    public int DstParentId { get; set; }
    public string Name { get; set; }
    public string Value { get; set; }
}

this.CreateMap<SrcParent, DstParent>()
    .ForMember(dst => dst.Id, opt => opt.Ignore())
    .ForMember(dst => dst.ConfigurationId, opt => opt.Ignore())
    .ForMember(dst => dst.DstChildren, opt => opt.MapFrom<MyValueResolver>());

public class MyValueResolver : IValueResolver<SrcParent, DstParent, List<DstChild>>
{
    public List<DstChild> Resolve(SrcParent source, DstParent destination, List<DstChild> destMember, ResolutionContext context)
    {
        /*
         * Many expensive operations that can be safely cached
         * on the resolver instance through the lifetime.
         */
    }
}

// Seed the mapper with an existing instance to hint the child conversion.
var dst = new DstParent
{
    ConfigurationId = 42
};

this.mapper.Map(src, dst);
