Need help using gst-play and gst-launch

[Kenneth Sloat]

Gstreamer is much better suited as a development platform to create custom media pipelines. Not that you couldn't use it to do what you are doing, but since it seems you are just trying to play videos with subtitles, then why not use VLC or similar?

In regards to subtitles, looks like there is an associate component subtitleoverlay:
