vmh264: stream not smooth [1/1]

PD#SWPL-28869

Problem:
H264 stream frequently not smooth

Solution:
cause:The number of inverted frames is inaccurate,
which results in the frame not being output in time
and the code stream is not smooth.
If the grammar has reverse frame number reoder_num_frames,
reoder_num_frames is preferred.

Verify:
