Hi

I am using matroska container to add subtitles to the video.
Inserting using buffer of appsrc.
Extract from buffer of appsinc, previously link it it "NewPadAdded" event

record pipeline:
appsrc ! text/x-raw ! matroskamux ! filesink

extract pipeline:
filesrc ! matroskademux ! text/x-raw format=pango-markup ! appsink


Try it yourself. And if no luck, i will send you my source code. :)

Mikl
