Xpra: Ticket #1751: deb: switch back to system libraries for ffmpeg on newer distros

Newer Debian / Ubuntu distros provide ffmpeg libraries that are recent enough for us to use:

stretch: 3.2.9 (maybe)
buster: 3.4.1
artful: 3.3.4
bionic: 3.4.1

We should deprecate our private package (#1256) for those distros and ensure we build against the system version. This may require using Conflicts and Replaces tags to ensure the package is not installed.

status changed from new to assigned

Done for "bionic" in r18106.

TODO:

test install with bionic alpha
test upgrade with artful

r18222: buster should now upgrade and remove the old ffmpeg-xpra

Let's not deal with stretch and artful, leaving it to the distro upgrade to make the transition to the new dependencies.

Wed, 21 Mar 2018 16:09:25 GMT - Antoine Martin: status changed; resolution set

status changed from assigned to closed
resolution set to fixed

This will do for now, hopefully ffmpeg 4.0 won't force us to use functions that aren't available in 3.4.x (see #1772)

Had to clean the build chroot and remove ffmpeg-xpra to ensure it doesn't get picked up by the build file because then the DEB both depends and conflicts with the ffmpeg package!

Thu, 26 Sep 2019 16:53:23 GMT - Antoine Martin:

Removed completely in v4: r23978.
