How to play audio and video in C++ using SDL2 and gstreamer

[Pedro GMail]

Hello all.

I'm looking for some example or explanation about how to play audio and 
video using SDL.

I'm looking for it in internet for more than two weeks and I cannot find 
any thing which helped me.

I've tried to convert the example wrote for gtk to SDL but I was unable 
to do that.

I've tried the example wrote for weston and I was unable to convert it 
to SDL2.

I had this task made with VLC but it's so slow and has memory lags.

Now I'm playing only the video stream with gstreamer. I extract the 
audio stream in a file apart and I play it with SDL.

I've found in the tutorials an example explaining that it is possible to 
create a pipe line with  a demuxer to play audio and video but actually 
it only plays audio.

Could you help me, please?

Thank you very much.

Pedro Becerra.
