\doxysubsection{Detailed Description}
Java version of webrtc\+::\+Video\+Frame and webrtc\+::\+Video\+Frame\+Buffer. A difference from the C++ version is that no explicit tag is used, and clients are expected to use \textquotesingle{}instanceof\textquotesingle{} to find the right subclass of the buffer. This allows clients to create custom \mbox{\hyperlink{interfaceio_1_1agora_1_1base_1_1_video_frame_1_1_buffer}{Video\+Frame.\+Buffer}} in arbitrary format in their custom Video\+Sources, and then cast it back to the correct subclass in their custom Video\+Sinks. All implementations must also implement the to\+I420() 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 Web\+R\+TC software encoders.
