You can just have youtube-dl download just the audio of the youtube video.

youtube-dl -x --audio-format mp3 http://www.bbc.co.uk/programmes/b07fl5bh

You can also set other formats for the audio

"best", "aac", "vorbis", "mp3", "m4a", "opus", or "wav"

Could you share a little more about your use case? You mentioned
multi-user and restricting based on group membership. Do you have
children that you don't want playing specific games, is this a work
environment?

The more information, the merrier. With the removal of games.eclass,
this case is going away, so if I or others can learn more about your use
case, we might be able to help you figure out how to better meet that
use case, or begin drafting features and/or documentation to make this
possible again.

Which features are your personal ebuilds using? Could you supply a

[gentoo-user] OT: what audio file format / container to play on Android.

[Stroller]

I've only recently started using my Android device for playing audio.

About once a week I listen to a podcast, which is usually an MP3 I've 
downloaded from NPR.org.

On my laptop I copy these to Google Drive (big shout to net-misc/drive) and 
then I can access then via Drive on my Android phone.

Google Drive on Android seems to play these audio files on a built-in player; 
its only controls are to skip forwards or backwards 30 seconds, but this is 
adequate for podcasts. 

I have here a BBC radio show that I downloaded a couple of weeks ago with 
net-misc/youtube-dl.

When downloaded it saves as an .mp4 file. I have also tried renaming it to .m4a 
but, either way, Google Drive complains "unable to process this video".

How do I need to process this audio to get it to play, please?

I'd obviously prefer to keep the same audio stream, rather than transcoding it. 
I assume that the player can handle AAC (??), it just needs to be in another 
container.

Thanks in advance for any suggestions,

Stroller.

I like the game group feature.  On a multiuser system it makes it fairly
simplistic to ensure access goes to whom I want to have access to those
games.  It also behaves similarly to other services which allow non root
users to run things based on their group membership.

I do not really care much about the ability to install outside of /usr, but
I can see that being very useful.  Of course, a symlink can provide this
same feature.

I have very few personal ebuilds that take advantage of much of the

I make use of the games group in my personal ebuilds.  I find some of the
other features provided in games.eclass potentially useful, but do not make
immediate needs of them.

I'm not sure what are all the features it provides.  But I do like that
(at least) some games share scores between users (in /var/games). It is
"nice to have" feature.

Also it is great advantage that emerge can ask for original game
installation media.  I'd feel more sorry for this one to be gone.

More games. ;-)

[gentoo-user] Security Onion on Gentoo

[James]

Hello,


So net-analyzer/suricata is all the rage now. The 'Security Onion' is
often pitched as a suricata distro. [1] Many of the commonly listed
packages that are part of the security onion are already in gentoo.

So, are there suricata users on gentoo-user? If so, do you use any
of the key listed software found on the security onion, as part of your
IDS/NDS/etc security toolset?


Would anyone be interested in combining these software components found
on the securtiy onion onto gentoo? [2]

[gentoo-user] Call for opinions and/or use cases regarding games.eclass

[Daniel Campbell]

Most of us know about the games.eclass history. Let's put that aside;
I'm looking for user consensus on packages that use(d) games.eclass.

1. Do you take advantage of games.eclass features, including restricting
game access to a given group and installing games outside of /usr and/or
on different media?

2. If yes, how do you feel about the removal of the eclass? Did you rely
on its functionality? Does your use case require it?

3. If yes, _what is your use case_? Which features are important to your
use case wrt games and what can Gentoo do to improve that?

We cannot make concrete decisions without concrete evidence, so please
answer and speak for your use case. This will serve as a public record
of interest, and might even inspire a few people. :)

Thanks for your time,

~zlg
