-- ** 'sendVideo'

-- | Request parameters for 'sendVideo'.
data SendVideoRequest = SendVideoRequest
  { sendVideoChatId :: SomeChatId -- ^ Unique identifier for the target chat or username of the target channel (in the format @channelusername)
  , sendVideoMessageThreadId :: Maybe MessageThreadId -- ^ Unique identifier for the target message thread (topic) of the forum; for forum supergroups only.
  , sendVideoVideo :: InputFile -- ^ Video to send. Pass a file_id as String to send an video that exists on the Telegram servers (recommended), pass an HTTP URL as a String for Telegram to get a video from the Internet, or upload a new video using multipart/form-data. More info on Sending Files »
  , sendVideoDuration :: Maybe Int -- ^ Duration of sent video in seconds
  , sendVideoWidth :: Maybe Int -- ^ Video width
  , sendVideoHeight :: Maybe Int -- ^ Video height
  , sendVideoThumbnail :: Maybe InputFile -- ^ Thumbnail of the file sent; can be ignored if thumbnail generation for the file is supported server-side. The thumbnail should be in JPEG format and less than 200 kB in size. A thumbnail's width and height should not exceed 320. Ignored if the file is not uploaded using multipart/form-data. Thumbnails can't be reused and can be only uploaded as a new file, so you can pass “attach://<file_attach_name>” if the thumbnail was uploaded using multipart/form-data under <file_attach_name>. More info on Sending Files »
  , sendVideoCaption :: Maybe Text -- ^ Video caption (may also be used when resending videos by file_id), 0-1024 characters after entities parsing
  , sendVideoParseMode :: Maybe ParseMode  -- ^ Send 'MarkdownV2', 'HTML' or 'Markdown' (legacy), if you want Telegram apps to show bold, italic, fixed-width text or inline URLs in your bot's message.
  , sendVideoCaptionEntities :: Maybe [MessageEntity] -- ^ A JSON-serialized list of special entities that appear in the caption, which can be specified instead of parse_mode
  , sendVideoHasSpoiler :: Maybe Bool -- ^ Pass 'True' if the video needs to be covered with a spoiler animation.
  , sendVideoSupportsStreaming :: Maybe Bool -- ^ Pass True, if the uploaded video is suitable for streaming
  , sendVideoDisableNotification :: Maybe Bool -- ^ Sends the message silently. Users will receive a notification with no sound.
  , sendVideoProtectContent :: Maybe Bool -- ^ Protects the contents of the sent message from forwarding and saving.
  , sendVideoReplyToMessageId :: Maybe MessageId -- ^ If the message is a reply, ID of the original message
  , sendVideoAllowSendingWithoutReply :: Maybe Bool -- ^ Pass True, if the message should be sent even if the specified replied-to message is not found
  , sendVideoReplyMarkup :: Maybe InlineKeyboardMarkup -- ^ Additional interface options. A JSON-serialized object for an inline keyboard, custom reply keyboard, instructions to remove reply keyboard or to force a reply from the user.
