Type Alias
FrameEncryptCallback
加密單幀 callback。回 0=成功；非 0=失敗（drop 該幀 + 發 FrameCryptoError 事件）。
typealias FrameEncryptCallback = @convention(c) (UInt32, UInt32, UnsafePointer<UInt8>?, Int, UnsafeMutablePointer<UInt8>?, Int, UnsafeMutablePointer<Int>?, UnsafeMutablePointer<UInt64>?, UnsafeMutableRawPointer?) -> Int32Discussion
參數：(mediaType, ssrc, plaintext, plaintextSize, ciphertext, ciphertextCapacity, outCiphertextSize, outCounter, userData)。
寫密文到
ciphertext[0..<ciphertextCapacity)、設outCiphertextSize（須 ≤ capacity）。設
outCounter為此幀 counter（SDK 序列化到 wire，decrypt 端原樣收到）。
