[gst-devel] Timestamping a video file with gstreamer

[jeetu.golani at gmail.com]

Hello,

First, I'm new to gstreamer and video manipulation and file formats in
general, therefore forgive me if what I ask is obvious :)

I would like to timestamp a video file sort of like how the timeoverlay and
clockoverlay elements do. However, I would like the time to begin from the
time the file was recorded. I'm using MythTV to record video and upon
recording I would like the file (or a clip) to be transcoded with the
timestamp - am open to having the final recording in any of the popular
container formats. My questions:

- Is there a way for me to overlay a user defined time? Can I somehow
manipulate the buffer or using some means introduce a time into the stream
using the timeoverlay/clockoverlay elements?
- Can I somehow introduce a timestamp in the file container itself and then
this gets used as the start time?

Google has so far not been able to provide me with my answers (or maybe I've
been looking in the wrong place). There is mention of a patch for
mencoder/mplayer that provided this functionality but that's obsolete now.
Same for ffmpeg that provided something similar using a vhook plugin.

I would sincerely appreciate your help on this. I'm definitely on my wits
end :)

Thanks

Bye for now
