[FFmpeg-user] Frames per second Conceptual Details.

[whoami Jils]

i am  a newbie and trying to understand the concepts behind ffmpeg/video.
fps -> frame per second , for example 25fps -> 25 frames are captured in a
second.
and 25 frames need to be displayed in a second [ correct me if i am wrong?
]


Now i  have written a simple video player in ffmpeg to display.  i read
frames by av_read_frame(),  if fps is 25, then does av_read_frame() returns
25 frames per second? how can i relate it?
