AVI file output

Products: Video Capture SDK .Net, Video Edit SDK .Net

AVI (Audio Video Interleave) was developed by Microsoft in 1992. AVI is a multimedia container format that stores both audio and video data in a single file. It supports synchronous audio-with-video playback. AVI files can contain both compressed and uncompressed data, offering flexibility but often resulting in large file sizes.

To capture video in AVI format using Video Capture SDK, you need to configure video output format using the AVIOutput class. You can set video and audio codecs and their various settings.

The same sample code can be used for Video Edit SDK .Net. Use the VideoEditCore class instead of VideoCaptureCore.

You can use dialog to set settings in UI or set settings in code.

Sample code

Create AVIOutput object

AVIOutput aviOutput = new AVIOutput();

Set AVI settings using the settings dialog

AVISettingsDialog aviSettingsDialog = new AVISettingsDialog(
  VideoCapture1.Video_Codecs.ToArray(),
  VideoCapture1.Audio_Codecs.ToArray());

aviSettingsDialog.ShowDialog(this);

aviSettingsDialog.SaveSettings(ref aviOutput);

Or

Set AVI settings without using the settings dialog

Get lists of audio and video codecs, fill combo boxes

foreach (string codec in VideoCapture1.Video_Codecs)
{
  cbVideoCodecs.Items.Add(codec);
}

foreach (string codec in VideoCapture1.Audio_Codecs)
{
  cbAudioCodecs.Items.Add(codec);
}

Set video settings

aviOutput.Video_Codec = cbVideoCodecs.Text;

Set audio settings

aviOutput.ACM.Name = cbAudioCodecs.Text;
aviOutput.ACM.Channels = 2;
aviOutput.ACM.BPS = 16;
aviOutput.ACM.SampleRate = 44100;
aviOutput.ACM.UseCompression = true;

Apply settings

Set AVI format settings for output

VideoCapture1.Output_Format = aviOutput;

Set video capture mode

VideoCapture1.Mode = VideoCaptureMode.VideoCapture;

Set file name (be sure that you have to write access rights)

VideoCapture1.Output_Filename = "output.avi";

Start capture (sync or async)

await VideoCapture1.StartAsync();
