One thing I'll note here: its a bit of a challenge to set up if
you're<br>
<pre wrap="">using the AirVideo Server for <b class="moz-txt-star"><span class="moz-txt-tag">*</span>Linux<span class="moz-txt-tag">*</span></b>. It takes about 30 seconds to
set up if you're using the AirVideo server for Mac OS X (and
presumably similar for Windows). I'm running AirVideo Server for Mac
OS X on an old 2GHz Core Duo iMac right now. Works well enough for all
mpeg2 content and lower resolution h.264/mpeg4/etc., but real-time
transcode unsurprisingly doesn't work particularly well for h.264 HD
content. Thus far though, its mostly all just a neat trick for me to
be able to play stuff on my iPad and iPhone. I'm rarely in a position
where I want to watch something and it doesn't make more sense to just
watch it using mythfrontend on a machine hooked to a TV at home, or
worst-case, mythfrontend on a laptop. If I traveled more or had a long
commute via public transit, maybe it'd be more useful.

<pre wrap="">Agreed, would be a nice integrated feature. And as mentioned, there
<b class="moz-txt-star"><span class="moz-txt-tag">*</span>is<span class="moz-txt-tag">*</span></b> some relevant related work being done to enable storing multiple

transcoded ipod-tailored version and the original version of a
recording. Not sure if any work is being done or considered wrt
on-demand real-time transcoding, beyond the mythweb flash player,
which (iirc) calls ffmpeg directly, it doesn't actually do the
transcode via mythbackend/mythtranscode. As they say in the
industry... Patches welcome! <span class="moz-smiley-s3" title=";)"><span>;)</span></span>

I'm finding that AirVideo transcodes 720p content recorded from an
HD-PVR just fine on the fly (serving up to an iPod Touch over
wifi). On my dual-core Athlon64 3GHz, ffmpeg peaks around 60% CPU
(seams to use both cores?), but only sporadically. My sons both
have iPod Touches, and I'm sure I'll soon see how it deals with two
HD programs being transcoded simultaneously, probably with a
recording, commflag, and remote front-end all running at the same
time ;-)<br>
<br>
I'd test 1080i content, but from some reason my cable company never
seems to serve up any 1080i content, and it saves me from having to
deal with de-interlacing, anyway.<br>
<br>
I'd love to submit a patch.... but I'm afraid I'm a product manager
rather than a developer, so the best I could do would be to submit a
functional specification or market requirements document! If any
developers want to volunteer, I'm happy to do the requirements
management ;-)<br>
