I am trying to output a screenshot of a video at an specified time and the resulting picture should have a black square with the time that was given initially.
So far I was only able to produce a screenshot using vframes from the example at the documentation on ffmpeg page which is this below:
ffmpeg -i input.flv -ss 00:00:14.435 -vframes 1 out.png
But I would like to add a timestamp in the resulting thumbnail or capture of the video which would show that '00:00:14.435' using arial fontface and a black square as background an yellow as fontcolor. Can this be done?.
