I would like to backup an ASF video stream with the time stamp (I mean the original recording date/time) on the output stream ?

Usage

I convert / store my video using the mkv format (Matroska) with libx264 (video) and aac (audio) codecs.

Assume the IP camera webcam user account is account, the password password

$ ffmpeg -i http://admin:alpha1237@webcam/videostream.asf -c:v libx264 -s 768X432 -crf 13 -b:v 2500K -pix_fmt yuv420p -c:a libfdk_aac output.mkv

This works fine on a tenvis JPT3815W camera

How to

I need to get the video timestamp available for display as a subtitle or other meta data field managed by standard video players, and ideally to be able to hide it or not during video reading.

Does anybody knows how to achieve that ?

Thanks in advance for your help.
