[Ffmpeg-devel] How does ffplay use the interpolation function to show video?

[Bo Liu]

Hi all:

I'm now using ffplay to play H.264 and rawvideo files.It is good that
ffplay could adjust the video area no matter how I change the window
size . ffplay can keep the width/height ratio when it plays video.
This is wonderful.

besides, when I play a H.264 file which is just in qcif
format(176x144) using options like"-x 640 -y 480", it works quite
well, seems like it uses a kind of interpolation method when it plays
video...

I checked ffplay.c many times in order to get information about this
and analyze it,but I couldn't find codes related to it.

anybody do me a favor?
thank you for your time.
