  MAIN_RESOLUTION_ABILITY      = 1,
  SUB_RESOLUTION_ABILITY       = 2,
  EVENT_RESOLUTION_ABILITY     = 3,
  FRAME_ABILITY                = 4,

}COMPRESSION_ABILITY_TYPE

COMPRESSION_STREAM_ABILITY: 码流压缩类型
MAIN_RESOLUTION_ABILITY: 主码流压缩分辨率
SUB_RESOLUTION_ABILITY: 子码流压缩分辨率
EVENT_RESOLUTION_ABILITY: 事件压缩参数分辨率
FRAME_ABILITY: 帧率能力
BITRATE_TYPE_ABILITY: 位率类型能力
BITRATE_ABILITY: 位率上限
THIRD_RESOLUTION_ABILITY: 三码流压缩分辨率
STREAM_TYPE_ABILITY: 码流类型
PIC_QUALITY_ABILITY: 图像质量
INTERVAL_BPFRAME_ABILITY: BP帧间隔
VIDEO_ENC_ABILITY: 视频编码能力
AUDIO_ENC_ABILITY: 音频编码能力
VIDEO_ENC_COMPLEXITY_ABILITY: 视频编码复杂度能力
FORMAT_ABILITY: 封装格式能力

byRes

保留，置为0

dwNodeNum

能力节点个数

struDescNode

节点能力参数结构

Remarks

我们举例说明各个能力类型与节点参数的关系：

能力类型（dwAbilityType）节点个数（dwNodeNum）节点参数（struDescNode->iValue）节点参数（struDescNode->byDescribe）

COMPRESSION_STREAM_ABILITY 3 0 “Main Stream”

COMPRESSION_STREAM_ABILITY 3 1 “Sub Stream”

COMPRESSION_STREAM_ABILITY 3 2 “Event Stream”

BITRATE_ABILITY 23 0 “16Kbps”

BITRATE_ABILITY 23 1 “32Kbps”

… … … …

BITRATE_ABILITY 23 -1 “Self-Define(0-65535kbps)”

能力类型（dwAbilityType）	节点个数（dwNodeNum）	节点参数（struDescNode->iValue）	节点参数（struDescNode->byDescribe）
COMPRESSION_STREAM_ABILITY	3	0	“Main Stream”
COMPRESSION_STREAM_ABILITY	3	1	“Sub Stream”
COMPRESSION_STREAM_ABILITY	3	2	“Event Stream”
BITRATE_ABILITY	23	0	“16Kbps”
BITRATE_ABILITY	23	1	“32Kbps”
…	…	…	…
BITRATE_ABILITY	23	-1	“Self-Define(0-65535kbps)”
