I had the former file in which I added your suggested stanza, but youtube 
videos dragged from FF continue to refuse to play (mpv crashes).  This is what 
is saved in the logs:

I trust you're aware you can use net-misc/youtube-dl until you get this

It's not clear to me that _any_ HTML5 audio is playing in your browser.

What version of Firefox do you have, what are it's USE flags?

Stroller.


...yes, sour are right :)
Until now no a single HTML5-video is playing its sound...


A better way:

Open mpv from your "start menu". Drag&drop the youtube video into the
mpv window.

No need to mess with terminals :-)


Hmm ... this won't work here.  :(

An exit code of 2 was returned.


You need to have the youtube-dl script installed (net-misc/youtube-dl). 
Make sure you use the ~arch version, since YouTube can change their APIs 
very fast, and that script has almost daily updates. But it's safe using 
~arch for this package, since it's just a python script.


To make sure you get the highest quality youtube format (including 
getting 60FPS video when available), make sure this line:


  ytdl-format=bestvideo[ext=webm]+bestaudio/bestvideo+bestaudio/best

Is in your mpv config file (default should be ~/.mpv/config). If you 
have a 1080p monitor, make sure you're excluding 4K. In that case, the 
above line should be:



ytdl-format=bestvideo[width<=?1920][ext=webm]+bestaudio/bestvideo[width<=?1920][ext=mp4]+bestaudio/best

In both cases, VP9 is given higher priority and H.264 is only used when 
no VP9 version of the video exists. (YouTube provides much higher 
quality video in the VP9 format.)

Have you passed the graphics card through to the VM?

Is the user trying to run the X server in the video group?

Systemd appears to complicate things greatly.  Have you tried to use
startx?

Can you attach x11vnc to the session (assuming that one does exist) to
see what would be on the screen from a remote machine?

Then you might be better off with no swap unless you put it on a file

btrfs and zfs

I won't put my data on btrfs for at least quite a while.

btrfs raid is software raid, zfs raid is software raid, mdadm is
software raid.  That makes three different sofware raids.

mdadm does have a very significant performance overhead.  ZFS mirror
performance seems to be rather poor.  I don't know how much overhead is
involved with zfs and btrfs software raid, yet since they basically all
do the same thing, I have my doubts that the overhead is significantly
lower than the overhead of mdadm.

There would be a possibility for more data integrity for the root file
system, assuming that btrfs is as reliable as ext4 on hardware raid.  Is
it?

That's about 10GB, mostly read and not written to.  It would be a
very minor improvement, if any.

 When you use hardware raid, it
 can be disadvantageous compared to btrfs-raid --- and when you use it
 anyway, things are suddenly much more straightforward because everything
 is on raid to begin with.

I have two drives to hold the root file system and the swap space.  The
raid controller they'd be connected do does not support using disks

It seems far more likely for a drive to fail when it is used than when
it is not used.

They are special cases.  Flash never really worked, and when it does,
it's pretty much unusable because it's too crappy.  Skype only kinda
works and is not usable due to total lack of privacy.

I wouldn't know how to do that.

In any case, the default is simply wrong.

There is no non-multilib profile one could use when they want a desktop
profile.  Perhaps multilib goes away in 20 years or so, or never.  That
doesn't help.

When a disk fails a swap partition is on, the system is likely to go
down.  Raid is not a replacement for backups.

Not at all, I'm seeing it as an advantage, especially when you want to
store large amounts of data.  Since I don't trust btrfs with that, I'm
using ZFS.

A system partition of 50 or 60GB --- of which about 10GB are used --- is
not exactly storing large amounts of data, and the data on it doesn't
change much.  In this application, checksums would still be a benefit,
yet a rather small one.  So as I said, the /relevant/ advantage of btrfs
is being able to make snapshots.  And that isn't worth the trouble.

Still needing swap partitions and removing the option to use swap files
instead simply defeats the purpose of btrfs and makes it significantly
harder to use.

I had the problem of html5 notplaying audio, I created a new profile,
andit madeit work and I just re-installed the add-ins I wanted.  I then
copied the entire profile  directory  so that in case this happened
again, I could always revert to my backup copy.
