prebuilt ffmpeg packages with QSV support for ubuntu

4

Suprisingly i couldn't find any ppa with prebuilt ffmpeg packages to add QSV (intel quicksync video) support.

Are there any, around? And isn't QSV added by default because it would rely on proprietary code? What other reason could there be, since it's a feature that >50% of the systems have these days?

19.10 + Nomachine nxclient_3.5.0-7_amd64.deb

4

so i'm a long time user of nomachine products. Lately i was (still am) happily using nxclient 3.5 on an ubuntu 18.04 to connect to a nomachine workstation 6.4 server (evaluation version).

Things are working great, minus the required replacement of the included libz.so.1.2.3 that apparently fails in 18.04 and has to be overwritten with the system version.

However, doing the same on a ubuntu 19.10 (and 20.04) doesn't work anymore, and the client appears to hang during connection with this sshlog:

NX> 105 NX> 280 Exiting on signal: 15

to compare with the same package ran on 18.04, here's the sshlog from the other machine:

I don't fully understand what could be the reason for nxssh hanging after the server has replied, since the installed package and binaries are the same.. Any suggestions?

ps: the reason i'm asking about nxclient 3.5 is because i already tried to use the latest client, but it somehow sucks much harder when using the "light" protocol (= old nx protocol) compared to the 3.5 client, and that's why i'd like to stick to it.

16.04 keeps waking up unmounted USB drives

0

I don't know if anybody else has experienced this, but i did on two systems on which i installed 16.04.

Essentially, if i plug a USB drive, unmount it (eject it in Nautilus), and put it to sleep (hdparm -y), i can hear the motor spinning down.

However, after a variable amount of time, the disk spins up again, and hdparm -C reports the disk to be active/idle again.

I also tried to disable gvfs from handling the drive, by putting its uuid into fstab, but even this does not help. Even with the disk unmounted, i keep getting it woken up by the system and i don't know why.

Can somebody suggest a way to diagnose what process might be responsible?

Running native ubuntu installation from fusion or parallels

0

my intention is to buy a macbook (retina) and triple boot it, with osX, w7 and ubuntu (>= 12.04, i still have to see which one offers the best compatibility). I found guides that explain how to do it without using the hybrid MBR, since all of these OSes are GPT aware. So far so good.

However, i would like to be able to run either of the two additional OSes both natively and virtualized. This means that the virtual machine (parallels, fusion or virtualbox) will be requested (by me) to run the OS from the physical partition.

Now, i already tried this with Windows 7 on a macbook, and it works nicely, without messing up anything (means i can boot one day from parallels, the next day natively, and everything is fine, even after installing parallels additions or whatever they are called).

My question is about ubuntu. I have not tried it, but i can reasonably expect that some things, for example the video drivers, are different in the two modes. Since these settings are normally stored in files (xorg.conf, for example), how easy is to interchangeably boot a native ubuntu both natively and virtualized?

PS: i know there will be some answers like "why do you ever want to do that?" or other non constructive comments. The reason why i want to do this is because we all know that these alternative OSes do not play nicely with the battery of the mac, when ran natively. So i want to be able to run them from osX when i will be on battery, to extend the usage range. On the other side, i want to be able to run natively these OS in order to use the graphic hardware directly (GPGPU and stuff like that)

update: I was also wondering: does parallels or fusion allow the guest to mount a physical partition (obviously if not mounted on the host)?
