UVC学习笔记是以最新的UVC1.5为基础,带你学习和了解最新的UVC规范和协议。

无压缩数据格式的官方文档为:USB_Video_Payload_Uncompressed_1.5.pdf,其下载地址为:https://www.usb.org/sites/default/files/USB_Video_Class_1_5.zip

UVC无压缩的数据格式支持四种数据格式类型,见下表:

无压缩的视频格式

无压缩的视频格式描述符定义了特定视频流的特征。 它用于承载 无压缩视频信息的格式,包括所有YUV变体。对应于USB INOUT端点的终端及其所属的接口支持一种或多种格式定义。 为了选择特定格式,主机软件将控制请求发送到相应的接口。

bFormatIndex字段包含此格式描述符的从一开始的索引,并且主机发出的请求用于设置和获取当前视频格式

guidFormat字段唯一标识在与此接口进行相应格式索引通信时应使用的视频数据格式。 对于视频源功能,主机软件将根据此字段中指定的格式部署相应的视频格式解码器(如果需要)。

bAspectRatioX和bAspectRatioY字段分别为视频场(隔行)数据指定图片高宽比的X和Y尺寸。 例如,对于16:9的显示,bAspectRatioX将为16,bAspectRatioY将为9。

无压缩的视频格式描述符后跟一个或多个 无压缩的视频帧描述符; 每个视频帧描述符都传达特定于该格式支持的帧大小的信息。 无压缩的视频格式描述符标识以下内容。

数据格式定义:

typedef struct _UNCOMPRESSED_VIDEO_FORMAT_DESCRIPTOR
{
    UINT8  bLength;
    UINT8  bDescriptorType;
    UINT8  bDescriptorSubtype;
    UINT8  bFormatIndex;
    UINT8  bNumberFrameDescriptor;
    GUID   guidFormat:指定了; //UINT[16]
    UINT8  bBitsPerPixel;
    UINT8  bDefaultFrameIndex;
    UINT8  bAspectRatioX;
    UINT8 bAspectRatioY;
    UINT8 bmInterlaceFlags;
    UINT8 bCopyProtect;
}UNCOMPRESSED_VIDEO_FORMAT_DESCRIPTOR;
  • bLength:该结构体长度,固定为27字节;
  • bDescriptorType:描述符类型,固定为0x24,代表视频流接接口。
  • bDescriptorSubtype:子描述符类型,固定为0x05,代表无压缩数据格式
  • bFormatIndex:数据格式编号。
  • bNumberFrameDescriptor:帧格式数量。
  • guidFormat:指定了无压缩数据格式的类型。
  • bBitsPerPixel:一个像素的多少位。如NV12为12位,YUV2为16位。
  • bDefaultFrameIndex:默认的帧格式。
  • bAspectRatioX:X宽度比例
  • bAspectRatioY:Y高度比例
  • bmInterlaceFlags:标志信息
  • bCopyProtect:是否支持视频流分流。

无压缩的帧描述符帧格式定义:

无压缩的视频帧描述符(或简称为帧描述符)用于描述解码视频和静止图像的帧尺寸以及特定流支持的其他特定于帧的特性。 一个或多个帧描述符遵循它们所对应的 无压缩视频格式描述符。 帧描述符还用于确定指定帧大小支持的帧间隔范围。

无压缩视频帧描述符仅适用于适用 无压缩视频格式描述符的视频格式。

bFrameIndex字段包含此帧描述符的从一开始的索引,并且主机请求使用它来设置和获取所使用格式的当前帧索引。 对于设备支持的每个相应格式描述符,此索引均基于一个索引。

支持的帧间隔范围可以是连续范围或一组离散值。 对于连续范围,dwMinFrameInterval,dwMaxFrameInterval和dwFrameIntervalStep指示范围的限制和粒度。 对于离散值,dwFrameInterval(x)字段指示在此帧大小下支持的帧间隔范围(以及帧速率)。 帧间隔是以100ns为单位的单个解码视频帧的平均显示时间。

typedef struct _UNCOMPRESSED_VIDEO_FRAME_DESCRIPTOR
{
    UINT8  bLength;
    UINT8  bDescriptorType;
    UINT8  bDescriptorSubtype;
    UINT8  bFrameIndex;
    UINT8  bmCapabilities;
    UINT16 wWidth;
    UINT16 wHeight;

    UINT32 dwMaxBitRate;
    UINT32 dwMaxVideoFrameBufferSize;
    UINT32 dwDefaultFrameInterval;
    UINT8  bFrameIntervalType;
    UINT32 adwFrameInterval[7];
} UNCOMPRESSED_VIDEO_FRAME_DESCRIPTOR;
Offset Field Size Value Description
0 bLength 1 Number 当bFrameIntervalType为0时,此描述符的大小以字节为单位;当bFrameIntervalType> 0时,此描述符的大小以字节为单位:26+(4 * n)
1 bDescriptorType 1 Constant CS_INTERFACE描述符类型
2 bDescriptorSubtype 1 Constant VS_FRAME_UNCOMPRESSED描述符子类型
3 bFrameIndex 1 Number 该帧描述符的索引
4 bmCapabilities 1 Number D0: 支持静止图像指定此帧设置是否支持静止图像。 这仅适用于具有使用静止图像捕获方法1的IN视频终结点的VS接口,在所有其他情况下应将其设置为0。 <br> D1: 固定帧速率指定设备是否在与此帧描述符关联的流上提供固定帧速率。如果启用了固定速率,则设置为1;否则,设置为0。 <br> D7..2: 保留,设置为0。
5 wWidth 2 Number 解码后的位图帧的宽度(以像素为单位)
7 wHeight 2 Number 解码后的位图帧的高度(以像素为单位)
9 dwMinBitRate 4 Number 指定最长帧间隔处的最小比特率,以bps为单位可以传输数据。
13 dwMaxBitRate 4 Number 指定可以传输数据的最短帧间隔的最大比特率,以bps为单位。
17 dwMaxVideoFrameBufferSize 4 Number 不建议使用此字段。指定压缩器将为视频帧或静止图像生成的最大字节数。Video Probe and Commit控件的dwMaxVideoFrameSize字段替换了此描述符字段。 为了与实现本规范较早版本的主机软件兼容,应选择该字段的值。
21 dwDefaultFrameInterval 4 Number 指定设备要指示用作默认值的帧间隔。 这必须是以下字段中所述的有效帧间隔。
25 bFrameIntervalType 1 编号指示如何设置帧间隔: <br> 0: 连续帧间隔 <br> 1..255: 支持的离散帧间隔数(n)
26… 请参阅以下帧间隔表。

连续帧间隔

Offset Field Size Value Description
26 dwMinFrameInterval 4 Number 支持的最短帧间隔(以最高帧速率),以100 ns为单位。
30 dwMaxFrameInterval 4 Number 支持的最长帧间隔(最低帧速率),以100 ns为单位。
34 dwFrameIntervalStep 4 Number 表示帧间隔范围的粒度,以100 ns为单位。

离散帧间隔

Offset Field Size Value Description
26 dwFrameInterval(1) 4 Number 支持的最短帧间隔(以最高帧速率),以100 ns为单位。
