End Of stream issue while playing mp4 file

Hi,
The issue i am facing is , Iam not able to playback the mp4 file created . The code is shown below.
This issue is happen when i use mp4mux.
Instead of using mp4mux if i use mpegtsmux (currently commented) then i am able to playback the recorded video.

Another thing i have noticed is if i use videotestsrc with mp4mux, then i am able to playback the recorded video.

AW: End Of stream issue while playing mp4 file

Hi, you have to wait for EOS to reach the filesink. When you have received the EOS Message, the MP4 file is complete. Then you can stop your pipeline.
