Codec 'mpeg1video' (1) is not supported by the bitstream filter 'h264_mp4toannexb'. Supported codecs are: h264 (27)

Hello, I'm tried to join several videos using the following code:

foreach (var file in recordFiles)
{
  var fileDuration = GetFileDuration(file);
  if (File.Exists(tempFile))
  {
    FFMpeg.Join(tempFile, file);
  }
  else
  {
    FFMpeg.SubVideo(file, tempFile, TimeSpan.FromSeconds(0), fileDuration);
  }
}

Unfortunatelly, I recieved the error mentioned in the topic when the FFMpeg.Join is executed.

Here is the entire error text:
