I had install YUView before on this computer with same Ubuntu 16.04 Xenial. But after some problem done and a loop boot, I was forced to reinstall Ubuntu 16.04 and lost applications installed. YUView is a part of them.

Now, I want to reinstall it (YUView is a software which can display .yuv file like .png, and without any issue about yuv format - 420, 422, ...), and I try to reinstall it by using same steps I use previously.

Problem : the PPA had changed (http://ppa.launchpad.net/beineri/opt-qt571-trusty/ubuntu), and the repertory Release didn't exist anymore for xenial. Anyone know how I can reinstall YUView ?

NB : step for install YUView (from their Github) :

  • sudo add-apt-repository ppa:beineri/opt-qt571-trusty -y
  • sudo apt-get update -qq
  • sudo apt-get install -qq qt57base; source /opt/qt57/bin/qt57-env.sh

Edit :

$ sudo apt update -qq
E: The repository http://ppa.launchpad.net/beineri/opt-qt571-trusty/ubuntu xenial Release  does not have a release file.

  • These steps are only needed for Ubuntu 14.04, because there are no Qt5 packages. As the README.md on the github page says use apt-get install qt5base to get Qt5 on Ubuntu 16.04

Download Qt 5 :

https://www.qt.io/download-qt-installer?hsCtaTracking=9f6a2170-a938-42df-a8e2-a9f0b1d6cdce%7C6cb0de4f-9bb5-4778-ab02-bfb62735f3e5

Install Qt 5 :

chmod +x qt-unified-linux-x64-3.0.5-online.run
sudo ./qt-unified-linux-x64-3.0.5-online.run

Qt5 installion software will start.

Select option that you want to install (default installation is suffisant, we didn't need to add others packages, we don't try to code a program with Qt).

NB: I add the sudo because you can have an issue with mirror host with an error like

Network error while downloading 'http://mirrors.ukfast.co.uk/sites/qt.io/online/qtsdkrepository/linux_x64/desktop/licenses/qt.license.gplv3except/1.0.0-1meta.7z' : Mirror host is unreachable.

Install YUView

Download the source code from Github, but there is the version 2.0 here (I don't use it, the 1st link is enough for me)

Extract your ZIP folder, you will get a folder named YUView; open a terminal inside, and use the following command :

qmake
make
sudo make install

YUView is now installed, you can now display your favorite YUV file and some format can be read (420, 422, 444 ...)

NB: YUView didn't detect the size of your picture, you must filled width and height option like I do (my picture is from a fisheye camera, 1536 x 1536)
