[Libav-user] Is an avfilter applied before encoding/decoding or after that

[Harry Ma]

Hi, All,

I wonder when a avfilter is applied? is it applied before encoding/decoding
or after that?
could anyone give me a brief introduction how ffmpeg process a video: what
happens to the pipe line from src input to the output sink?

thanks very much.

Best Regards,
Harry
