Good time of the day,
I have heard that such a feature exists, but i've lost the reference and have been unable to find it now. I am looking for a way to use the file as the input for all the fileter options passed to libav's avconv (or ffmpeg).
I know i can do that via a command line with -f or -vf, but there are two problems: i often reuse the same settings and sometimes i need to reuse the particular approach after bash has already lost that particular command line from history.
If i'm mistaken and there's no way to do that, also kindly let me know.
