Spent some time figuring out which existing (free of charge) media player could display current frame-number or resolutions up to milliseconds. I focused my search on Windows platform.
- VLC:
Unable to find a way to step frame-by-frame
- VirtualDub: Yes - it is on by default. Noticed the limited types of media container support. It works with AVI, mpg, but not mp4.
- Media Player Classic: Yes - but I am only able to show it as OSD, not the status / information area.
- Open the video file
- Configure the OSD option to display 'frame number' from Media Player Classic menu: Play -> Filters -> ffdshow Video Decoder -> Properties
- Turn on OSD option from ffdshow (available from windows taskbar)
