GStreamer encountered a general stream error

[JongIlLee]

Hi

Now I'm trying to play mp4 files

After trying to play mp4 file to demuxing

A stream error may occur.

My code will let me know if there are any problems

Ask advice. thank you!

* error : GStreamer encountered a general stream error.

um...Add to I want to make the final application is

An application with the pipeline, such as an attached image

Combine the mp4 file and one subtitle file is application.

If wrong with respect to the structure, please advise.
