Processing of each frame

[ransha]

Hi,
My requirement is to receive video stream in VLC on ubuntu server and read info from each frame. I have download VLC source code tarball from [url]http://get.videolan.org/vlc/3.0.8/vlc-3.0.8.tar.xz[/url], and trying to modify the source code before creating executable to log each frame details.

I see some frame details in file location:
vlc\modules\stream_out\transcode\encoder\video.c (transcode_video_framerate_apply function)

but does looks like the right spot as i do not see each frame hits this method in this class.
Can anyone guide me to look at right class or file.
I will really appreciate any help on this. Thanks.
