[Kwiver-users] KWIVER Docker Usage: KWIVER_PLUGIN_PATH

[Matt Leotta]

Dave,

That all makes sense to me.  The FFMPEG arrow is now stable and the
preferred way to access video, so it should certainly be enabled by default
if FFMPEG is available.

I think Docker is an increasingly important way of distributing and
integrating KWIVER into other systems.  I'm in favor of more regular builds.

There have been several important bug fixes in KWIVER since the last
release.  I'm thinking we should make a new patch release soon from the
release branch.  I would argue that missing FFMPEG in Docker is a bug that
we should back port to the release branch so that the next release of
KWIVER has working tools.
