我正在尝试使用为FFMPEG制作的NReco.VideoConverter包装类来连接视频。
我有三个具有相同帧速率和相同帧大小的视频文件。
这就是我所做的。
string toconcatfile = @"C:\Users\Alan\Desktop\Black.mp4";
string output1 = @"C:\Users\Alan\Desktop\output1.mp4";
string output2 = @"C:\Users\Alan\Desktop\output2.mp4";
string finaloutput = @"C:\Users\Alan\Desktop\finaloutput.mp4";
当我将toconcatfile添加到最终转换方法时，所有三个视频的帧速率都为25，视频帧大小却失败了。
当它只是output1和output2意味着toconcatfile中必须有不同的设置时，它才有效。
这是我尝试过的。
FFMpegConverter fFMpeg = new FFMpegConverter();
//Slices first video
ConvertSettings settings = new ConvertSettings
{
VideoFrameRate = 25,
VideoFrameSize = FrameSize.hd480,
MaxDuration = startcut,
AudioSampleRate = 44100
};
//Slices second video
ConvertSettings settings2 = new ConvertSettings
{
VideoFrameRate = 25,
VideoFrameSize = FrameSize.hd480,
Seek = endcut,
AudioSampleRate = 44100
};
//Copies framerate and size from the previous video to the concatenation video
ConvertSettings settings3 = new ConvertSettings
{
VideoFrameRate = 25,
VideoFrameSize = FrameSize.hd480,
MaxDuration = 4,
AppendSilentAudioStream = true,
AudioSampleRate = 44100
};
string newblack = @"C:\Users\Alan\Desktop\newblack.mp4";
//Slice method called
fFMpeg.ConvertMedia(pathtofile, Format.mp4, output1, Format.mp4, settings);
fFMpeg.ConvertMedia(pathtofile, Format.mp4, output2, Format.mp4, settings2);
fFMpeg.ConvertMedia(toconcatfile, Format.mp4, newblack, Format.mp4, settings3);
String[] inputfiles = new String[2];
inputfiles[0] = output1;
inputfiles[1] = newblack;
//inputfiles[1] = output2;
ConcatSettings concatSettings = new ConcatSettings
{
//CustomOutputArgs = output1+" "+ toconcatfile+ " "+output2+ " -filter_complex \"[0:v:0][0:a:0][1:v:0][1:a:0][2:v:0][2:a:0]concat=n=3:v=1:a=1[outv][outa]\" -map \"[outv]\" - map \"[outa]\""
};
fFMpeg.ConcatMedia(inputfiles, finaloutput, Format.mp4, concatSettings);
有人可以帮忙吗？
编辑：我收到异常消息 - “无效参数（退出代码：1）”，
