WebM file output

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

WebM: WebM is an open, royalty-free media file format designed for the web. Introduced in 2010, it was developed by Google to provide high-quality video streaming with low computational overhead. WebM is optimized for use with HTML5 and supports VP8 and VP9 video codecs and Vorbis and Opus audio codecs.

You must configure the output format using the WebMOutput class to capture video in WebM format. You can use dialog to set settings in UI or set settings in code.

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

Sample code​

Create WebMOutput object​

var webmOutput = new WebMOutput();

Set WebM settings using the settings dialog​

WebMSettingsDialog settingsDialog = new WebMSettingsDialog();
settingsDialog.ShowDialog(this);
settingsDialog.SaveSettings(ref webmOutput);

Or

Set WebM settings without using the settings dialog (basic sample)​

webmOutput.Video_Mode = VP8QualityMode.Realtime;
webmOutput.Video_EndUsage = VP8EndUsageMode.VBR;
webmOutput.Video_Encoder = WebMVideoEncoder.VP8;
webmOutput.Video_Bitrate = 2000;

webmOutput.Audio_Quality = 80;

Apply settings​

Set WebM format settings for output​

VideoCapture1.Output_Format = webmOutput;

Set the video capture mode​

VideoCapture1.Mode = VideoCaptureMode.VideoCapture;

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

VideoCapture1.Output_Filename = "output.webm";

Start capture (sync or async)​

await VideoCapture1.StartAsync();
