"ffplay" Interactive Commands

While playing a movie with the "ffplay", you can also control the playing process using the following interactive commands:

q, ESC            quit  f                 toggle full screen  p, SPC            pause  a                 cycle audio channel in the current program  v                 cycle video channel  t                 cycle subtitle channel in the current program  c                 cycle program  w                 cycle video filters or show modes  s                 activate frame-step mode  left/right        seek backward/forward 10 seconds  down/up           seek backward/forward 1 minute  page down/page up seek backward/forward 10 minutes  mouse click       seek to percentage in file corresponding                     to fraction of width  

Let use these interactive commands to locate the ending position of the "Anchor 'Great Escape'" segment.

1. Run "ffplay" to play "Tony_reelshow_2009_512kb.mp4". The movie player starts.

2. Click the player screen at about 22% width position. The player seeks to 00:00:42 position and displays the following on the console:

Seek to 22% ( 0:00:42) of total duration ( 0:03:11)       B f=0/0  

3. Press "p" to stop the play. The player displays a still image of the "Anchor 'Great Escape'" segment.

4. Press "s" to step 1 frame forward. The player shows the following on the console:

  42.03 A-V:  0.028 fd=  96 aq=    5KB vq=    9KB sq=    0B f=0/0  

5. Press <right> arrow key to seek forward for 10 seconds. The player displays a still image of the next movie segment with the following on the console:

  52.03 A-V:    nan fd=  96 aq=    1KB vq=   19KB sq=    0B f=0/0  

6. Press <left> arrow key to seek backward for 10 seconds. Then press "s" many times until you see the last image of the "Anchor 'Great Escape'" segment. It should be at 00:00:43.33.
