Writing via a temp file is way more expensive. (The old thumbnailer did
that.)
Dedicated pipe sounds like the way to go.

Title:
vs-thumb should not rely on standard streams to communicate result
image back
Status in thumbnailer package in Ubuntu:
New
Bug description:
vs-thumb right now streams extracted data to stdout by default (see
[1]). The approach is brittle in the sense that any component (e.g.,
gstreamer or gstreamer plugin) writing to stdout can easily break the
thumbnail. We have zero control over stdout and should thus either:
(1.) Rely on specifying an explicit temporary destination file or
(2.) Open a dedicated communication pipe to communicate back the resulting
thumbnail to the calling process.
Please also see [2.] for the respective product bug.
