Extraction of Overlay Data from Video File

[胡珩]

i think you can't. because the text has became pixels mixed with video frames. why not backup the text before textoverlay?

Hi,

I am using the following command to overlay text onto the video and store it.

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

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.

Thanks & Best Regards,

Pradeep Nalawade
