You can use ffmpeg for b4a and use

FFMpegVideoView1.SetVideoLayout(FFMpegVideoView1.VIDEO_LAYOUT_ZOOM)

 

[victormedranop]

and how to reduce size ?
FFMpegVideoView1.SetVideoLayout(FFMpegVideoView1.VIDEO_LAYOUT_STRETCH)

is not working.

reduce 20%.
try inside a panel but did not work.

You can start with this code:

   'Calculation Proportion Movie
      Dim vidfile, Dir, VideoName As String
      Dir = File.DirInternal
      VideoName = "vid_bokeh.mp4"
      vidfile = File.Combine(Dir, VideoName)
  
      Dim rfl As Reflector
      Dim obj As Object
      Dim b As Bitmap
  
      obj = rfl.CreateObject("android.media.MediaMetadataRetriever")
      rfl.Target = obj
      rfl.RunMethod2("setDataSource", vidfile, "java.lang.String")
      b = rfl.RunMethod3("getFrameAtTime", 0, "java.lang.long", 3, "java.lang.int")
  
  
      Dim new_width, new_height As Int

If ( b.Width / b.Height < Activity.Width / Activity.Height ) Then 'Landscape
            new_width = Activity.Width + 100dip
            new_height = b.Height * ( Activity.Width / b.Width )
            Panel_Wait.AddView(vv_sopra_pannello, 0, 0, new_width,new_height )   
    Else
            new_height = Activity.Height + 100dip
            new_width = b.Width * ( Activity.Height / b.Height)
            Panel_Wait.AddView(vv_sopra_pannello, - ( new_width / 2 ) + ( Activity.Width / 2) , - (( new_height / 2 ) - ( Activity.Height / 2 )),  new_width,new_height )

End If

This is proportional for all screen, but you can reduce or increase example:

.....
          new_height = b.Height - ((20/b.Height) * b.Height) .......'Reduce 20%
          new_width = b.Width - ((20/b.Width) * b.Width) .......'Reduce 20%
          Panel_Wait.AddView(vv_sopra_pannello,...... - ( new_width / 2 ) + ( Activity.Width / 2) , - (( new_height / 2 ) - ( Activity.Height / 2 )),  new_width,new_height )
.....
