I've been successful at getting vlc to stream a file from a network file share to an old chromecast (which doesn't support hevc / x265 directly) using the commands below (the file is encoded using x264).

vlc -vv --sout "#chromecast" --sout-chromecast-ip=192.168.1.111 --sout-chromecast-conversion-quality=0 --demux-filter=demux_chromecast "/home/vid/nfst/video1_x264.mp4" 

I'm trying to do the same thing with an HEVC / x265 file but it looks like it needs to be trans-coded "in real-time" before it gets to the chromecast. Does anybody know how I can go about doing this with vlc using command line syntax?

PS: I have tried the VLC GUI but the OLD chromecast doesn't support HEVC / x265 files the audio plays but the video is black.

PPs: I'm using VLC media player 3.0.7.1 Vetinari (revision 3.0.7.1-0-gf3940db4af) running Ubuntu 18.04 64bit.
