+<p>Typical usage:</p>

+<ul>

+<li>Call Create() to create a new video encoder resource.</li>

+<li>Call GetSupportedFormats() to determine which codecs and profiles are available.</li>

+<li>Call <a class="el" href="classpp_1_1_video_encoder.html#ad2c47c10cfe92a3bf41e204d326560c7" title="Initializes a video encoder resource.">Initialize()</a> to initialize the encoder for a supported profile.</li>

+<li>Call <a class="el" href="classpp_1_1_video_encoder.html#a5c5fabe6a00afe6b8849bbc612183bb2" title="Gets a blank video frame which can be filled with video data and passed to the encoder.">GetVideoFrame()</a> to get a blank frame and fill it in, or get a video frame from another resource, e.g. <code>PPB_MediaStreamVideoTrack</code>.</li>

+<li>Call <a class="el" href="classpp_1_1_video_encoder.html#a39755b4e3aee295d8ba509da9904e5cd" title="Encodes a video frame.">Encode()</a> to push the video frame to the encoder. If an external frame is pushed, wait for completion to recycle the frame.</li>

+<li>To destroy the encoder, the plugin should release all of its references to it. Any pending callbacks will abort before the encoder is destroyed.</li>
