Unable to do textoverlay #288

Closed premalathasuresh closed 3 years ago

premalathasuresh commented 3 years ago

Hi Am new to gstreamer,

My requirement is to add textoverlay on video. I have installed gstreamer1.0, and run below command for to get the result.

gst-launch-1.0 filesrc location=/home/premalatha/backup/result.ts ! textoverlay text="Hello" ! filesink location=/home/premalatha/backup/resultoutput.ts

Here result.ts is my input file and I expect the resulted data to be present at resultoutput.ts.

Could you please let me know if I have missed out any steps. or any other library to be added here.

Error displayed on screen : premalatha@ATX-InfoSysVM04:~$ gst-launch-1.0 filesrc location=/home/premalatha/backup/result.ts ! textoverlay text="Hello" ! filesink location=/home/premalatha/backup/resultoutput.ts Setting pipeline to PAUSED ...

You'd need to decode the actual video elementary stream first. This is not gstreamer-imx specific - it is a general GStreamer question instead. Please consult the GStreamer mailing list, or visit the GStreamer IRC channel.
