Femto bolt多台相机同步录制问题 #91

实现两台Femto bolt同步录制。
首先我分别从k4aviewer上将从机和主机分别运行,可以看到两台设备是同步的。
然后进行录制工作,我使用k4arecorder.exe运行命令行进行录制。
首先对于从机设备打开命令行运行k4arecorder.exe --device 0 --external-sync subordinate --imu OFF -e 16000 -r 15 -l 10 output-2.mkv
会显示[subordinate mode] Waiting for signal from master并等待主设备录制开启。
然后对于主机设备运行k4arecorder.exe --device 1 --external-sync master --imu OFF -e 16000 -r 15 -l 10 output-1.mkv
此时主设备还在初始化还没开始录制,而从机设备已经开始录制了,显示Started recording,主机此时还在初始化,过了两三秒,主机初始化完才显示Started recording,导致两台设备录制不同步,从机设备总是提前录制完。
随后查看录制保存的视频显示的总是从机提前主机开始录制。并且,一机一台电脑和两机一台电脑两种连接都会出现这个问题。
这好像是从机只要接收到主机启动的脉冲就开始录制,但是此时主机还没完全启动完,也就没办法录制。从而导致两台设备没办法同时录制。
请问有什么解决方法吗
