Own Arguments - Package add incorrect parameters
oreleraki opened this issue · comments
Part of my use cases, i have a concatenation which doesn't supported by Xabe and i tried to pass my own arguments.
I have noticed that Xabe is adding arguments which produce me incorrect results.
The added parameters i didn't wanted are: -map 0:0 -map 0:1 -n
Temporary solution
I have added -i input.mp4
to my parameter and removed .AddStream
builder function, so the source code will ignore it.
C#
var mediaInfo = await FFmpeg.GetMediaInfo(fileName);
string @params = "-filter_complex \"[0:v]trim=start=10:duration=10,setpts=PTS-STARTPTS[v0]; [0:v]trim=start=70:duration=10,setpts=PTS-STARTPTS[v1]; [0:v]trim=start=190:duration=10,setpts=PTS-STARTPTS[v2]; [v0][v1][v2]concat=n=3:v=1[final]\" -map \"[final]\"";
IConversionResult conversionResult = await FFmpeg.Conversions.New()
.AddStream(mediaInfo.Streams)
.AddParameter(@params)
.SetOutput("concat-video.mp4")
.Start();
"C:\ffmpeg-5.1.2-full_build\ffmpeg-5.1.2-full_build\bin\ffmpeg.exe" -i "H:\input.mp4" -map 0:0 -map 0:1 -n -filter_complex "[0:v]trim=start=10:duration=10,setpts=PTS-STARTPTS[v0]; [0:v]trim=start=70:duration=10,setpts=PTS-STARTPTS[v1]; [0:v]trim=start=190:duration=10,setpts=PTS-STARTPTS[v2]; [v0][v1][v2]concat=n=3:v=1[final]" -map "[final]" "concat-video.mp4"
Hello @oreleraki
I don't think there is anything I can do about that.
For more complex scenarios if you know FFmpeg I suggest using .Start(string params) overload.
That builder should fulfill most of user cases but it's not perfect :)

Thank you @tomaszzmuda, that helps a lot.
