Comment(by mdean):
The attached patch,
mythtv-7136-remove_GeneratePreviewRemotely_setting.patch , removes the
"Generate preview image remotely" setting and does all preview generation
from the backend process. It does not remove the preview generator's
ability to be used for local versus remote generation--it just makes the
playbackbox use the remote generator.
The recent improvements to UI responsiveness before previews are created
and during preview generation make the amount of time it takes to generate
a preview less important. Furthermore, since the local preview generation
was only used for the occasional changed recording (after setting a
bookmark or cutlist or watched flag or ...) and for recordings in
progress, the setting was mostly unused. And, finally, since the days of
the hugely-powerful frontend system with underpowered backend systems seem
to be over and many users are actually taking the opposite approach (and
creating powerful backends with low-powered frontends), this configuration
should work well for everyone--even users who don't install mythbackend on
dedicated frontend systems (or who are working on platforms to which
mythbackend has not been ported).
Even with my ca. 2002 Athlon XP 2000+ system generating previews for HDTV
broadcasts (which it can not decode in real time), the preview generation
seems sufficiently fast. Therefore, rather than test for a local
mythbackend binary before calling it, or even changing the defaults to
enable the "Generate preview image remotely" setting, it makes more sense
to just remove the setting completely.
Nigel: Until the setting is removed, you can simply enable the "Generate
preview image remotely" setting in Utilities/Setup|Setup|TV
Settings|Playback.
