psdk开发的负载设备用DjiPayloadCamera_SendVideoStream函数发送视频流时，带宽最大是多少，实时视频流码率是8M会报如下错误

调用DjiHighSpeedDataChannel_SetBandwidthProportion设置视频流数据带宽比例设置成百分比，数据流带宽和下载流数据带宽比例设置成0

    能否帮忙看一下视频流数据，8M的视频流传到遥控器就卡，一直报上面的错，4M的码率就不卡

    码流检测工具检测是通过的，发送数据到遥控器就卡顿

    日志看是飞机端的通道问题，已经在排期优化了，有可测试的固件会再次同步给您的。

    测试固件什么时候可以有

    下一版本的飞机固件会修改到此处（预计3月发布，具体时间还请您再留意下公告），但是还要再确认下您的问题是否和我们的已知问题一致，请问下您使用的是Custom通道还是DJI-H264通道？您可以使用DjiPayloadCamera_GetVideoStreamState函数看看带宽情况，也可以将结果给我们确认下。后续Custom H264不会再支持了，这几个版本还会继续维护的，因此我们建议您使用DJI H264通道。

    用的是DJI-H264（DJI_CAMERA_VIDEO_STREAM_TYPE_H264_DJI_FORMAT）

    我们下个版本会优化这个通道的设置，下个版本预计是3月中发布，具体释放日期还请您以官方的发布公告为准。另外您可以同步用DjiPayloadCamera_GetVideoStreamState看看传输时的带宽情况。

    在8M码流下，通道处于繁忙状态

    还有就是负载设备使用的是静态ip(192.168.120.2/255.255.0.0),但不管是动态ip还是静态ip，8M码流都是一样的问题

    视频流传输走的高速通道，官方文档上说M300上发送高速数据需要将通道类型设置为custom的PSDK_CAMERA_VIDEO_STERAM_TYPE_H264_CUSTON_FORMAT的格式，本地设置是DJI_CAMERA_VIDEO_STREAM_TYPE_H264_DJI_FORMAT，所以这两种格式下个版本都会优化吗

    目前我们确认到会优化DJI_CAMERA_VIDEO_STREAM_TYPE_H264_DJI_FORMAT的传输效果，但是不会优化PSDK_CAMERA_VIDEO_STERAM_TYPE_H264_CUSTON_FORMAT，因为Custom是透传通道，这个不好去定制化或适配某个平台。
