FFmpeg编码的RGB视频无法在Azure Kinect Viewer中播放的问题求助

大家好，我遇到了一个困扰很久的问题，想请各位帮忙排查下：

我用Azure Kinect DK设备录制了一段视频，原本能在Azure Kinect Viewer（版本v1.4.1）里正常播放。但当我用FFmpeg对其中提取出的RGB单通道视频（原始的RGB.mkv本身可以正常用该播放器打开）进行编码后，生成的视频就无法在Azure Kinect Viewer中播放了，打开时会弹出提示：

Failed to open Recording

我已经尝试了两种不同的FFmpeg编码命令，分别是：

• 基于H.264编码的命令：

  ffmpeg -i .\RGB.mkv -c:v libx264 -preset veryfast -crf 18 -c:a aac -b:a 128k RGG_Enc.mkv
  

• 基于MJPEG编码的命令：

  ffmpeg -i .\RGB.mkv -c:v mjpeg -pix_fmt yuvj422p -q:v 2 output.mkv
  

除此之外，我还试过其他不同的编码格式和参数组合，但结果都一样，没法在Azure Kinect Viewer里正常播放。

为了方便大家排查问题，我附上了原始RGB.mkv的ffprobe输出信息：

有没有大佬能指点一下，我该怎么调整FFmpeg的参数，才能让编码后的视频正常在Azure Kinect Viewer里播放？
