我现在遇到一个问题，和华为视频终端（VP9039A）通过H323协商的时候，想协商1080P30，结果华为发给我的是1080P10,如果我把华为视频格式修改为Auto,就和华为协商成704*400 30帧；感觉很奇怪。
定义的参数：
struct PluginCodec_H323GenericParameterDefinition H2641080P_h323params[] =
{
{{1,0,0,0,0},41, PluginCodec_H323GenericParameterDefinition::PluginCodec_GenericParameter_BooleanArray,{64}},
{{1,0,0,0,0},42, PluginCodec_H323GenericParameterDefinition::PluginCodec_GenericParameter_unsignedMin, {85}},
{{1,0,0,0,0},3, PluginCodec_H323GenericParameterDefinition::PluginCodec_GenericParameter_unsignedMin, {492}},
{{1,0,0,0,0},4, PluginCodec_H323GenericParameterDefinition::PluginCodec_GenericParameter_unsignedMin, {32}},
};

struct PluginCodec_H323GenericCodecData H2641080P_h323GenericData[] = {
{OpalPluginCodec_Identifer_H264_Generic, 7680, 4, H2641080P_h323params}
};

struct PluginCodec_Definition h264encInfo
{
/* encoder */

60, }}, /* maximum number of frames per packet */
96,//RTP_DataFrame::DynamicBase, /* IANA RTP payload code */
sdpH264, /* RTP payload name */
NULL, /* create codec function */
NULL, /* destroy codec */
NULL, /* encode/decode */
EncoderControls, /* codec controls */
PluginCodec_H323Codec_generic, /* h323CapabilityType */
(struct PluginCodec_H323GenericCodecData *)&H2641080P_h323GenericData/* h323CapabilityData */
};

用wireshark抓包能力协商的时候
