I tried to set blocksize of gstbase source to 100 and I am able to disable
subtitles without blocking the video, however if the subtitles start little bit
late(e.g: once the credits are over, if they are appearing at the start of
clip), then video is blocked till a buffer(worth 100 bytes) gets released.

On the other hand, if I keep trying disable/enable of subtitle multiple times
at some point no effect is observed w.r.t subtitle appearing/disappearing --
filesrc is in paused state :(, while the rest of things seem to be happening
fine in playbin(flags property(GST_PLAY_FLAG_TEXT) is being set appropriately).
