I've just spent a few hours looking very very carefully at high-speed video of an industrial process. Here is a proposal for mplayer to make this an even better tool for analysis/kinematics.
Add an --analysis flag to mplayer. This would do the following:
- Turn on OSD, and show the frame number as well as H:m:s. Eg:
0:01:02::21 [or, show fractions of a second: 0:01:02.62 ]
- Make the left/right arrow keys advance/reverse only by 1 second rather than 10.
- When video is paused, the seek controls (eg left/right arrow) should jump to the next point, but NOT resume playback.
- See also wish #2214, for single-stepping backwards.
- At the end of the video, the window should not automatically close. It should remain open (we're doing a lot of seeking back and forward, and don't want to quit if we jump to the end).
- Don't auto-hide the mouse pointer.
- Turn the mouse pointer into cross-hairs. When it is clicked on the video, print (to stdout) the timestamp (to the nearest frame) and the x:y co-ordinates of the click.
- When the mouse is right-clicked, also turn that pixel red (and keep it red till we quit).
- Optional extra: allow some way to measure distances and speeds.
Thank you for your consideration. :-)
