hi各位，在hi3798MV100平台使用以下命令进行h264编码
gst-launch-1.0 -vv videotestsrc !  'video/x-raw,format=I420, width=1280,height=720,framerate=10/1' ! videoconvert ! omxh264enc ! h264parse ! filesink location=test.mkv -e

输出如下：

然后将 test.mkv 放在本地上使用以下命令
mplayer test.mkv -fps 10
播放，其图像如下

不会有变化
请教下这个问题如何排查，
另外我有两个疑问
1. test.mkv 中未有 fps信息，必须手动 -fps 10 进行指定
2. [FBD]report EOS buffer !PTS = 14600000, 0, len= 0   的 14600000 代表啥 ，视频录制时间 Execution ended after 0:00:03.616382904 是，但是播放时长比0.3秒要长，感觉跟 14600000 这个有关。
