// including at least a Track Section and a number of SimpleBlocks each
// containing a single encoded video or audio frame. WebM container has no
// Trailer.
// Clients will push encoded VPx or AV1 video frames and Opus or PCM audio
// frames one by one via OnEncoded{Video|Audio}(). libwebm will eventually ping
// the WriteDataCB passed on constructor with the wrapped encoded data.
// WebmMuxer is designed for use on a single thread.
