i think you can't. because the text has became pixels mixed with video frames. why not backup the text before textoverlay?<br><br>At 2016-12-23 13:07:50, "PRADEEP NALAWADE" <pradeep.nalawade@funambolo.co.in> wrote:<br> <blockquote id="isReplyContent" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">
<p>Hi,</p>
<p>I am using the following command to overlay text onto the video
and store it.</p>
<p><b>gst-launch-1.0 -e imxv4l2videosrc ! textoverlay text="Video 1"
valignment=top halignment=left font-desc="Sans, 60" !
timeoverlay ! vpuenc_h264 ! mp4mux ! filesink
location=video_264.mp4</b></p>
<p>Now I have to extract the overlay information from the stored
video file. Is there any command available to extract the overlay
information from the stored video.</p>
<p>Thanks & Best Regards,</p>
