currenty developing a media player with gstreamer...not using playbin
I'd need to manage subtitles yet.
Though I'm not very familiar with subtitiles, I understand the various
formats availables from a demuxer pad or from an external source.
It looks like /textoverlay /and /subtitleoverlay /are 2 famous plugins to
manage subtitles...knowing that /subtitleoverlay /maanges more formats than
Is there a difference between the 2 plugins regarding the performances and
HW accel considerations ?
Secondly, if we consider a classic pipeline for a video playback: whether a
subtitle is selected or not by the user, is it a bad idea to keep a
/textoverlay /or /subtitleoverlay /element in the pipeline ? With the
subtitle pad not sinnked ? Is there a major performance penalty ?
