Properties
AllowOpenGop
public bool AllowOpenGop { get; set; }Specifies whether an open Group of Pictures (GOP) structure should be
allowed or not. The default is false.
| Property Value | |
|---|---|
| Type | Description |
Boolean | |
AqStrength
public double AqStrength { get; set; }Specify the intensity of the adaptive quantizer (AQ). Must be between 0 and 1, where 0 disables the quantizer and 1 maximizes the quantizer. A higher value equals a lower bitrate but smoother image. The default is 0.
| Property Value | |
|---|---|
| Type | Description |
Double | |
BFrameCount
public int BFrameCount { get; set; }The number of consecutive B-frames. Must be greater than or equal to zero. Must be less than [gop_frame_count][google.cloud.video.livestream.v1.VideoStream.H264CodecSettings.gop_frame_count] if set. The default is 0.
| Property Value | |
|---|---|
| Type | Description |
Int32 | |
BitrateBps
public int BitrateBps { get; set; }Required. The video bitrate in bits per second. Minimum value is 10,000.
- For SD resolution (< 720p), must be <= 3,000,000 (3 Mbps).
- For HD resolution (<= 1080p), must be <= 15,000,000 (15 Mbps).
| Property Value | |
|---|---|
| Type | Description |
Int32 | |
BPyramid
public bool BPyramid { get; set; }Allow B-pyramid for reference frame selection. This may not be supported
on all decoders. The default is false.
| Property Value | |
|---|---|
| Type | Description |
Boolean | |
EntropyCoder
public string EntropyCoder { get; set; }The entropy coder to use. The default is cabac.
Supported entropy coders:
cavlccabac
| Property Value | |
|---|---|
| Type | Description |
String | |
FrameRate
public double FrameRate { get; set; }Required. The target video frame rate in frames per second (FPS). Must be less than or equal to 60. Will default to the input frame rate if larger than the input frame rate. The API will generate an output FPS that is divisible by the input FPS, and smaller or equal to the target FPS. See Calculating frame rate for more information.
| Property Value | |
|---|---|
| Type | Description |
Double | |
GopDuration
public Duration GopDuration { get; set; }Select the GOP size based on the specified duration. The default is
2s. Note that gopDuration must be less than or equal to
[segment_duration][google.cloud.video.livestream.v1.SegmentSettings.segment_duration], and
[segment_duration][google.cloud.video.livestream.v1.SegmentSettings.segment_duration] must be divisible
by gopDuration. Valid range is [2s, 20s].
All video streams in the same channel must have the same GOP size.
| Property Value | |
|---|---|
| Type | Description |
Duration | |
GopFrameCount
public int GopFrameCount { get; set; }Select the GOP size based on the specified frame count.
If GOP frame count is set instead of GOP duration, GOP duration will be
calculated by gopFrameCount/frameRate. The calculated GOP duration
must satisfy the limitations on gopDuration as well.
Valid range is [60, 600].
| Property Value | |
|---|---|
| Type | Description |
Int32 | |
GopModeCase
public VideoStream.Types.H264CodecSettings.GopModeOneofCase GopModeCase { get; }| Property Value | |
|---|---|
| Type | Description |
VideoStream.Types.H264CodecSettings.GopModeOneofCase | |
HeightPixels
public int HeightPixels { get; set; }Required. The height of the video in pixels. Must be an even integer. Valid range is [180, 1080].
| Property Value | |
|---|---|
| Type | Description |
Int32 | |
Profile
public string Profile { get; set; }Enforces the specified codec profile. The following profiles are supported:
baselinemain(default)high
The available options are FFmpeg-compatible Profile Options. Note that certain values for this field may cause the transcoder to override other fields you set in the [H264CodecSettings][google.cloud.video.livestream.v1.VideoStream.H264CodecSettings] message.
| Property Value | |
|---|---|
| Type | Description |
String | |
Tune
public string Tune { get; set; }Enforces the specified codec tune. The available options are FFmpeg-compatible Encode Options Note that certain values for this field may cause the transcoder to override other fields you set in the [H264CodecSettings][google.cloud.video.livestream.v1.VideoStream.H264CodecSettings] message.
| Property Value | |
|---|---|
| Type | Description |
String | |
VbvFullnessBits
public int VbvFullnessBits { get; set; }Initial fullness of the Video Buffering Verifier (VBV) buffer in bits. Must be greater than zero. The default is equal to 90% of [vbv_size_bits][google.cloud.video.livestream.v1.VideoStream.H264CodecSettings.vbv_size_bits].
| Property Value | |
|---|---|
| Type | Description |
Int32 | |
VbvSizeBits
public int VbvSizeBits { get; set; }Size of the Video Buffering Verifier (VBV) buffer in bits. Must be greater than zero. The default is equal to [bitrate_bps][google.cloud.video.livestream.v1.VideoStream.H264CodecSettings.bitrate_bps].
| Property Value | |
