[FFmpeg-user] Query regarding mkvtimestamp_v2 filter

[tarun singhal]

Hi All,

I need help in understanding what does  mkvtimestamp_v2 filter do.
I tried to search documentation around it but couldnt find. All I could
find was this command
*ffmpeg -i usopen.mp4 -f mkvtimestamp_v2 -qscale:v 0 a.txt*

which apparently seems to give out timestamp of each frame in the video.

Can you please help?
What other options are available with formatting of this filter output.

Regards,
Tarun
