<Parameter name="encodingPreference">

视频编码器偏好。详见 [FENUMWRAP_ENCODING_PREFERENCE](/zh-CN/api-reference/rtc/unreal-blueprint/enum-encodingpreference)。

</Parameter>
<a id="compressionpreference"></a>
<Parameter name="compressionPreference">

视频编码的压缩偏好。详见 [ECOMPRESSION_PREFERENCE](/zh-CN/api-reference/rtc/unreal-blueprint/enum-compressionpreference)。

</Parameter>
<a id="encodealpha"></a>
<Parameter name="encodeAlpha">

当视频帧包含 Alpha 通道数据时，设置是否将 Alpha 数据编码并发送至远端：

- `true`：对 Alpha 数据进行编码发送。
- `false`：（默认）不对 Alpha 数据进行编码发送。
