I have a stream, that I can successfully decode with ffmpeg, with this command line:

ffmpeg -f image2pipe -vcodec png -r 30 -i -

Now I want to to pipe it directly to vlc. I tried this one with unsuccessfully:

vlc - --avcodec-codec png --avformat-format image2pipe --avformat-options \{r=30\}

I suspect that the arguments are even ignored. How can i accomplish this?

Did you specify the codec for VLC to use like so?

vlc --codec avcodec ...
