AW: Gstreamer output to a buffer then file On Jetson tegra Tx2

[Thornton, Keith]

Hi, you could do this by ending one pipeline with appsink and starting a separate pipeline with appsrc. There are probably other ways to do this depending upon what you are really trying to achieve.

Hi Experts, 

I am new to gstreamer  world of multimedia, i am stuck in gstreamer issues, kindly help me solve it.
I am doing  capturing + encoding video + encoding audio + muxing on tegra tx2.

Current task :
completed task.
1) capturing video+  encoding video *i used tegra multimedia API's* and storing in buffer .


2) capturing audio + encoding audio + muxing *i  am using gstreamer API
code*.
gstreamer takes encode video data from my bufferers +  captures audio +
encode audio data and mux it and write to file .mp4
*
Problem :*

*I want the muxed data to be stored in local bufferers* (char* pst =
(char*)malloc(10000);) 

1) How can i store gstreamer output  to local buffer?
or 2) How to pass local buffer to  gstreamer to store its output.
