使用gstreamer创建的MP4文件无法在Window Media Player上播放

现代公园

我使用gstreamer创建了mp4文件。

gst-launch-1.0 videotestsrc num-buffers=10 ! "video/x-raw, format=(string)NV12, width=(int)1280, height=(int)720, framerate=(fraction)30/1"  ! videoconvert ! avenc_mpeg4 ! avmux_mp4 ! filesink location=/tmp/test.mp4

我可以使用Mplayer，VLC等播放它。但是我不能在Windows Media Player上播放它。

我选中了MP4框。但似乎没有问题。我如何尝试其他方式？
