@ywangwxd , could you please send me a sample of the problematic video? Also, issue are mpp related only? Does video successfully processed by the software decoder?

Just point Timebase and PTS. Simplest way, set Timebase to the value inverted to required FPS, for example 1/60 and use sequential counter for the frames: 1, 2, 3, 4,...

Too busy, sorry. Look into https://github.com/h4tr3d/avcpp/blob/decode-raw-h264/example/api2-samples/api2-decode-raw-h264.cpp sample. Will be moved into master.
