'screencast' using host-x11 no longer works

[DennisLfromGA]

My HP Chromebook 14 just updated to using Freon and my 'screencast' script is now broken - and it won't get up. I get the error:

No Chromium OS X server is available.

The pertinent command is:

sudo enter-chroot -c /usr/local/chroots -n screencast host-x11 avconv -f alsa -ac 2 -ab 128k -i pulse -f x11grab -r 30 -s 1366x768 -i :0.0 -vcodec libx264 -preset ultrafast -crf 0 Downloads/movie1.mkv

It's using the chroot-bin/host-x11 script and the error stems from this logic, I believe:

if [ ! -f "/sys/class/tty/tty0/active" ]; then
    err="No Chromium OS X server is available."

I tried adding the 'xorg' xmethod to no avail.

Shall I try to add xmethod 'xiwi' to see if that fixes it?
Is there another, better way to run this or am I now out of luck?

There's no X server in Chromium OS with freon, so abusing host-x11 won't work anymore. You'll either need to make avconv directly access the display data (not sure if possible), or use some Chromium OS native mechanism for screencasting.

Well those options are out of my wheelhouse so I guess 'screencast' is dead :(
Maybe Francois Beaufort will have some ideas, I may try to run it by him.

@DennisLfromGA Anything new, yet?

[DennisLfromGA]

@TheBlackLion - Nope, I'm afraid not - as yet...
I tried a few things with the 'xiwi' app but haven't yet found anything that works.
The combination of options possible with 'avconv' are extensive, to say the least, so there are many more to try. I'm just not sure I'll have the patience or knowledge to fix it. ;(

Wait... if you use xiwi or Sommelier, and use ChromiumOS built-in screencasting feature, isn't that still a kind of screencasting via Crouton, or am I misunderstanding?

[DennisLfromGA]

@VenomousSteam81,

If you didn't notice this was an issue from 2015 before freon was introduced and it's closed, there may be ways to do it now with the advent of screencasting and other newer ChromeOS features.
