Great work. Thanks!

I saw that the ffmpeg-kit has several packages:
github.com

Releases · tanersener/ffmpeg-kit

Fork of https://github.com/arthenica/ffmpeg-kit. Contribute to tanersener/ffmpeg-kit development by creating an account on GitHub.

Can I use only the min package or the video package to decrease the final size of the app?

Thanks for your support.

Is there a way to use the filter with (') in ExecuteAsync instead ExecuteWithArgumentsAsync?
(quote: because of this part :force_style='fontsize=70,PrimaryColour=&H00FF99AA' we need to use ExecuteWithArgumentsAsync as ExecuteAsync will remove ' from command)

I try to merge drawtext with subtitles. It works with ExecuteAsync, but I can't use the force_style.
B4X: 
FFmpegCommand = "-i " & InputFilePath & " -vf 'drawtext=fontsize=40:text=" & TextOverVideo & ":y=85','subtitles=" & InputSubtitlesPath & "' -acodec copy -y " & OutputFilePath

If I use the same command in ExecuteWithArgumentsAsync, don't works.
B4X: 
Dim FFmpegCommandArray() As String = Array As String("-i", InputFilePath, "-vf", "drawtext=fontfile=" & InputFontPath & ":text=" & TextOverVideo & ":fontsize=50:fontcolor=white", "subtitles=" & InputSubtitlesPath, "-acodec", "copy", "-y", OutputFilePath)

Any help are welcome. Thanks.

This code work:
B4X: 
Dim FFmpegCommandArray() As String = Array As String("-i", InputFilePath, "-vf", "drawtext=fontfile=" & InputFontPath & ":text=" & TextOverVideo & ":fontsize=50:fontcolor=white:x=50:y=100", "-acodec", "copy", "-y", OutputFilePath)

Thanks.
I found the problem. I was using the separator to drawtext and subtitle filters in FFmpegCommandArray and this is the problem.
Here is the correct code:
B4X: 
Dim FFmpegCommandArray() As String = Array As String("-i", InputFilePath, "-vf", "drawtext=fontfile=" & InputFontPath & ":text=" & TextOverVideo  & ":fontsize=50:fontcolor=white:x=(w-text_w)/2:y=100" & ", subtitles=" & InputSubtitlesPath & ":force_style='fontsize=30,PrimaryColour=&H00FFFFFF,OutlineColour=&HFF000000,Bold=1,Alignment=10'", "-acodec", "copy", "-y", OutputFilePath)
