[Availability]

The package x265 is already in Ubuntu universe.
The package x265 build for the architectures it is designed to work on.
It currently builds and works for architectures: amd64 arm64 armhf i386 ppc64el
riscv64 s390x

Link to package https://launchpad.net/ubuntu/+source/x265

[Rationale]

- The package x265 will not generally be useful for a large part of
  our user base, but is important/helpful still because it is required
  for libheif
- Additionally new use-case enabled by this is encoding H.265/HEVC video
  stream
- The package x265 is a new runtime dependency of package libheif that
   we intend to support
- It would be great and useful to community/processes to have the
  package TBD in Ubuntu main, but there is no definitive deadline.

[Security]

- Had 3 security issues in the past
  - https://ubuntu.com/security/CVE-2017-13135
  - https://ubuntu.com/security/CVE-2017-13666
  - https://ubuntu.com/security/CVE-2017-8906
  There are no open CVEs againt current (3.5.2) version of the package.

- no executables in `/sbin` and `/usr/sbin`

- Package does not install services, timers or recurring jobs
- Packages does not open privileged ports (ports < 1024)
- Packages does not contain extensions to security-sensitive software

[Quality assurance - function/usage]

- The package works well right after install

[Quality assurance - maintenance]

- The package is maintained well in Debian/Ubuntu and has not too many
  and long term critical bugs open
  - Ubuntu https://bugs.launchpad.net/ubuntu/+source/x265/+bug
  - Debian https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=x265
- The package has important open bugs, listing them:
  - https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1006211
    FTBS on kfreebsd, not applicable
  - https://bugs.launchpad.net/ubuntu/+source/x265/+bug/1915012
    Feature request to enable build option
  - https://bugs.launchpad.net/ubuntu/+source/x265/+bug/1909949
    SIGSEGV on previous version, need more information, e.g. input file
    to investigate. Did not occur during my testing
    (sample file encoding with ffmpeg)

- The package does not deal with exotic hardware we cannot support

[Quality assurance - testing]

- The package does not run a test at build time because
  it is not implemented in the package.
  The upstream contains TestBench target which can be enabled through
  -DENABLE_TESTS=on passed to cmake. This creates TestBench executable
  with unit tests.

- The package runs an autopkgtest, and is currently passing on
  this amd64 arm64 armhf i386 ppc64el riscv64 s390x list of architectures,
  link to test logs https://autopkgtest.ubuntu.com/packages/x/x265

- The package does have not failing autopkgtests right now

[Quality assurance - packaging]

- debian/watch is present and works

- debian/control defines a correct Maintainer field

  `lintian --pedantic` as an extra post to this bug.
- Lintian overrides are not present

[UI standards]
