Package tvi.webrtc

Class VideoFrame

  • All Implemented Interfaces:

    public class VideoFrame
    extends java.lang.Object
    implements RefCounted
    Java version of webrtc::VideoFrame and webrtc::VideoFrameBuffer. A difference from the C++ version is that no explicit tag is used, and clients are expected to use 'instanceof' to find the right subclass of the buffer. This allows clients to create custom VideoFrame.Buffer in arbitrary format in their custom VideoSources, and then cast it back to the correct subclass in their custom VideoSinks. All implementations must also implement the toI420() function, converting from the underlying representation if necessary. I420 is the most widely accepted format and serves as a fallback for video sinks that can only handle I420, e.g. the internal WebRTC software encoders.

      • VideoFrame

        public VideoFrame​(VideoFrame.Buffer buffer,
                          int rotation,
                          long timestampNs)
        Constructs a new VideoFrame backed by the given buffer. Note: Ownership of the buffer object is tranferred to the new VideoFrame.

        public int getRotation()
        Rotation of the frame in degrees.
      • getTimestampNs

        public long getTimestampNs()
        Timestamp of the frame in nano seconds.
      • getRotatedWidth

        public int getRotatedWidth()
      • getRotatedHeight

        public int getRotatedHeight()
      • retain

        public void retain()
        Description copied from interface: RefCounted
        Increases ref count by one.
        Specified by:
        retain in interface RefCounted
      • release

        public void release()
        Description copied from interface: RefCounted
        Decreases ref count by one. When the ref count reaches zero, resources related to the object will be freed.
