watermark
資源會識別在指定頻道影片播放期間顯示的圖片。你也可以指定圖片連結的目標頻道,以及決定浮水印在影片播放期間的顯示時間和長度。
方法
這個 API 支援 watermarks
資源的下列方法:
- 設定
- 將浮水印圖片上傳至 YouTube,並為頻道設定浮水印。
- 未設定
- 刪除頻道的浮水印圖片。
立即試用。
屬性
下表定義這個資源中顯示的屬性:
屬性 |
timing |
object
timing 物件會封裝資訊,說明頻道浮水印圖片在影片播放期間的顯示時間。 |
timing.type |
string
決定影片播放期間浮水印圖片顯示時間的方法。如果值為 offsetFromStart ,則 offsetMs 欄位代表影片開始的偏移量。如果值為 offsetFromEnd ,則 offsetMs 欄位代表影片結尾的偏移量。 |
timing.offsetMs |
unsigned long
時間偏移量 (以毫秒為單位),決定影片播放期間宣傳項目出現的時間。type 屬性的值會決定偏移量是從影片開頭還是結尾開始計算。 |
timing.durationMs |
unsigned long
浮水印圖片的顯示時間長度 (以毫秒為單位)。 |
position |
object
position 物件會封裝影片中顯示浮水印圖片的空間位置相關資訊。 |
position.type |
string
在影片播放器中,宣傳項目顯示的位置。
這個屬性的有效值如下: |
position.cornerPosition |
string
播放器中顯示促銷項目的角落。項目一律會顯示在播放器的右上角。
這個屬性的有效值如下: |
imageUrl |
string
頻道浮水印圖片的網址。YouTube 會產生這個網址,並在 watermark.set 要求的 API 回應中傳回。 |
imageBytes |
bytes
浮水印圖片的大小 (以位元組為單位)。 |
targetChannelId |
string
浮水印圖片連結的頻道 YouTube 頻道 ID。 |

Key actions include setting a watermark by uploading an image and specifying its `targetChannelId` for linking. The `timing` object defines when the image appears using `type`, `offsetMs`, and `durationMs`. The `position` object, set to 'corner', determines the spatial location, specifically `topRight`. Watermarks can be removed using the `unset` method.

You can also specify a target channel to which the image will link as well as timing details that determine when the watermark appears during video playbacks and the length of time it is visible.\n\nMethods\n-------\n\nThe API supports the following methods for `watermarks` resources:\n\n[set](/youtube/v3/docs/watermarks/set)\n: Uploads a watermark image to YouTube and sets it for a channel.\n\n[unset](/youtube/v3/docs/watermarks/unset)\n: Deletes a channel's watermark image.\n [Try it now](/youtube/v3/docs/watermarks/unset#try-it).\n\nResource representation\n-----------------------\n\nThe JSON structure below shows the format of a `watermarks` resource: \n\n```carbon\n{\n \"#timing\": {\n \"#timing.type\": string,\n \"#timing.offsetMs\": unsigned long,\n \"#timing.durationMs\": unsigned long\n },\n \"#position\": {\n \"#position.type\": string,\n \"#position.cornerPosition\": string\n },\n \"#imageUrl\": string,\n \"#imageBytes\": bytes,\n \"#targetChannelId\": string\n}\n```\n\n### Properties\n\nThe following table defines the properties that appear in this resource:\n\n| Properties ||\n|---------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `timing` | `object` The `timing` object encapsulates information about the time during a video playback when a channel's watermark image will display. |\n| timing.`type` | `string` The timing method that determines when the watermark image is displayed during the video playback. If the value is `offsetFromStart`, then the `offsetMs` field represents an offset from the start of the video. If the value is `offsetFromEnd`, then the `offsetMs` field represents an offset from the end of the video. |\n| timing.`offsetMs` | `unsigned long` The time offset, specified in milliseconds, that determines when the promoted item appears during video playbacks. The `type` property's value determines whether the offset is measured from the start or end of the video. |\n| timing.`durationMs` | `unsigned long` The length of time, in milliseconds, that the watermark image should display. |\n| `position` | `object` The `position` object encapsulates information about the spatial position within the video where the watermark image will display. |\n| position.`type` | `string` The manner in which the promoted item is positioned in the video player. Valid values for this property are: - corner |\n| position.`cornerPosition` | `string` The corner of the player where the promoted item will appear. The item always appears in the upper right corner of the player. Valid values for this property are: - `topRight` |\n| `imageUrl` | `string` The URL for the channel's watermark image. YouTube will generate this URL and return it in the API response to a `watermark.set` request. |\n| `imageBytes` | `bytes` The size of the watermark image, in bytes. |\n| `targetChannelId` | `string` The YouTube channel ID of the channel that the watermark image links to. |"]]
