## ◆ VD_3840x2160

final VideoDimensions io.agora.rtc2.video.VideoEncoderConfiguration.VD_3840x2160 = new VideoDimensions(3840, 2160)
| static

Not supported.

## ◆ STANDARD_BITRATE

final int io.agora.rtc2.video.VideoEncoderConfiguration.STANDARD_BITRATE = 0
| static

0: The standard bitrate mode. In this mode, the bitrates under the Live Broadcast and Communication profiles differ:

- In the Communication profile, the video bitrate is the same as the base bitrate.
- In the Live Broadcast profile, the video bitrate is twice the base bitrate.

## ◆ COMPATIBLE_BITRATE

final int io.agora.rtc2.video.VideoEncoderConfiguration.COMPATIBLE_BITRATE = -1
| static

-1: The compatible bitrate mode. In this mode, the bitrate stays the same regardless of the profile. If you choose this mode for the Live Broadcast profile, the video frame rate may be lower than the set value.

## ◆ DEFAULT_MIN_BITRATE

final int io.agora.rtc2.video.VideoEncoderConfiguration.DEFAULT_MIN_BITRATE = -1
| static

(For future use) Use the default minimum bitrate.

## ◆ DEFAULT_MIN_FRAMERATE

final int io.agora.rtc2.video.VideoEncoderConfiguration.DEFAULT_MIN_FRAMERATE = -1
| static

(For future use) The default minimum frame rate.

## ◆ DEFAULT_MIN_BITRATE_EQUAL_TO_TARGET_BITRATE

final int io.agora.rtc2.video.VideoEncoderConfiguration.DEFAULT_MIN_BITRATE_EQUAL_TO_TARGET_BITRATE = -2
| static

-2: (For future use) Set minimum bitrate the same as target bitrate.

## ◆ dimensions

VideoDimensions io.agora.rtc2.video.VideoEncoderConfiguration.dimensions

The video frame dimensions (px), which is used to specify the video quality and measured by the total number of pixels along a frame's width and height. The default value is 960 × 540. Users can either set the resolution manually or choose from the following options:

- VD_120x120.
- VD_160x120.
- VD_180x180.
- VD_240x180.
- VD_320x180.
- VD_240x240.
- VD_320x240.
- VD_424x240.
- VD_360x360.
- VD_480x360.
- VD_640x360.
- VD_480x480.
- VD_640x480.
- VD_840x480.
- VD_960x540.
- VD_960x720.
- VD_1280x720.

Note
  - The value of the dimension does not indicate the orientation mode of the output ratio. For how to set the video orientation, see ORIENTATION_MODE.
  - Whether 720p+ can be supported depends on the device. If the device cannot support 720p, the frame rate will be lower than the one listed in the table.

## ◆ frameRate

int io.agora.rtc2.video.VideoEncoderConfiguration.frameRate

The video frame rate (fps). The default value is 15. Users can either set the frame rate manually or choose from the following options. We do not recommend setting this to a value greater than 30.

- FRAME_RATE_FPS_1(1).
- FRAME_RATE_FPS_7(7).
- FRAME_RATE_FPS_10(10).
- FRAME_RATE_FPS_15(15).
- FRAME_RATE_FPS_24(24).
- FRAME_RATE_FPS_30(30).
- FRAME_RATE_FPS_60(60).

## ◆ minFrameRate

int io.agora.rtc2.video.VideoEncoderConfiguration.minFrameRate

(For future use) The minimum video encoder frame rate (fps). The default value is {DEFAULT_MIN_FRAMERATE(-1)} (the SDK uses the lowest encoder frame rate).

## ◆ bitrate

int io.agora.rtc2.video.VideoEncoderConfiguration.bitrate

The bitrate of the video (Kbps). Refer to the table below and set your bitrate. If you set a bitrate beyond the proper range, the SDK automatically adjusts it to a value within the range. You can also choose from the following options:

- STANDARD_BITRATE(0): (Recommended) The standard bitrate mode. In this mode, the bitrates differ between the Live Broadcast and Communication profiles:
  - In the Communication profile, the video bitrate is the same as the base bitrate.
  - In the Live Broadcast profile, the video bitrate is twice the base bitrate.
- COMPATIBLE_BITRATE(-1): The compatible bitrate mode. In this mode, the bitrate stays the same regardless of the profile. If you choose this mode for the Live Broadcast profile, the video frame rate may be lower than the set value.

Agora uses different video codecs for different profiles to optimize the user experience. For example, the Communication profile prioritizes the smoothness while the Live Broadcast profile prioritizes the video quality (a higher bitrate). Therefore, We recommend setting this parameter as STANDARD_BITRATE = 0.

Video Bitrate Table

Resolution | Frame rate（fps） | Base Bitrate (Kbps, for Communication) | Live Bitrate (Kbps, for Live Broadcast)
--- | --- | --- | ---
160 × 120 | 15 | 65 | 130
120 × 120 | 15 | 50 | 100
320 × 180 | 15 | 140 | 280

320 × 240 | 15 | 200 | 400
240 × 240 | 15 | 140 | 280

360 × 360 | 15 | 260 | 520
640 × 360 | 30 | 600 | 1200
360 × 360 | 30 | 400 | 800
480 × 360 | 15 | 320 | 640
480 × 360 | 30 | 490 | 980

480 × 480 | 15 | 400 | 800
640 × 480 | 30 | 750 | 1500
480 × 480 | 30 | 600 | 1200
848 × 480 | 15 | 610 | 1220
848 × 480 | 30 | 930 | 1860
640 × 480 | 10 | 400 | 800
1280 × 720 | 15 | 1130 | 2260
1280 × 720 | 30 | 1710 | 3420
960 × 720 | 15 | 910 | 1820
960 × 720 | 30 | 1380 | 2760

Note
  The base bitrate in this table applies to the Communication profile. The Live Broadcast profile generally requires a higher bitrate for better video quality. We recommend setting the bitrate mode as STANDARD_BITRATE = 0. You can also set the bitrate as the base bitrate value × 2.

## ◆ minBitrate

int io.agora.rtc2.video.VideoEncoderConfiguration.minBitrate

(For future use) The minimum encoding bitrate (Kbps). The Agora SDK automatically adjusts the encoding bitrate to adapt to the network conditions. Using a value greater than the default value forces the video encoder to output high-quality images but may cause more packet loss and hence sacrifice the smoothness of the video transmission. That said, unless you have special requirements for image quality, Agora does not recommend changing this value.

Note
  This parameter applies to the Live Broadcast profile only.

## ◆ orientationMode

ORIENTATION_MODE io.agora.rtc2.video.VideoEncoderConfiguration.orientationMode

The orientation mode. See ORIENTATION_MODE.

## ◆ degradationPrefer

DEGRADATION_PREFERENCE io.agora.rtc2.video.VideoEncoderConfiguration.degradationPrefer

The video encoding degradation preference under limited bandwidth: {DEGRADATION_PREFERENCE}.

## ◆ mirrorMode

MIRROR_MODE_TYPE io.agora.rtc2.video.VideoEncoderConfiguration.mirrorMode

If mirror_type is set to VIDEO_MIRROR_MODE_ENABLED, then the video frame would be mirrored before encoding.

## ◆ advanceOptions

AdvanceOptions io.agora.rtc2.video.VideoEncoderConfiguration.advanceOptions

The video hardwareEncoding: #hardwareEncoding and The video compressionPreference: #compressionPreference.

## ◆ codecType

VIDEO_CODEC_TYPE io.agora.rtc2.video.VideoEncoderConfiguration.codecType

The codec type of the local video stream. See #VIDEO_CODEC_TYPE. The default value is `VIDEO_CODEC_H265 (3)`.
