[vlc-devel] RE : VLC as a frame-server : some problems remains.

[Video Guru]

As per your suggestions, I created an avencoder dll (based on the
dummy encoder.c), but I am unable to figure out how to put it into the
sout chain, and how to specify the width/height/chroma/audio format. I
just want RV32 video and 2 channel 48khz audio.

Can you please guide by giving a simple argv string, my encoder is called avmem.

Electricity is actually made up of extremely tiny particles called
electrons, that you cannot see with the naked eye unless you have been
