Currently, I have ffplay setup to draw the timestamp as overlay text, so that I can manually record the value of the paused frame. This getting tedious and I was thinking of extracting it with a custom program that monitors stdout.
I noticed that when I turn on the log output, I can see the debug information for the text formatting of the drawn timestamp. When paused, I can read back several lines to see the timestamp that matches the one shown in the overlay text. It seems consistently 4 formatting debug messages back, but that is probably unreliable.
Any ideas on how this can be done and reliably?
