Is this possible?

Hi,

I dont know if this is possible or not but it would really be nice if it was.

I have a main Frontend/Backend that I use to watch HD and SD and it works great. I am thinking about adding anew frontend with an Xbox. I know that the xbox doesnt have the power to play HD but I can think of two alternatives that would work great for me and others i believe.

The best option...

Record the show with my HD card. Then have it automatically transcoded to Xvid HR HDTV keeping the original.

I know how to set to keep the file myth renames it to .old

What i would want ideally when I watch the recording with my HD viewer it would play the .old file that has the full res video but when i connect with my xbox it would play the Xvid version.

The working but not so good method...

When i record a show use my analog and HD card to record a show. Then when playing the show i could choose between which show I would like to watch. But how would i set it to record both shows? Create two recordings and set the tuner to the corrisponding version?

Thanks,
Mitchell

I think what you describe might be possible. The way I would do it is to
have a second backend (maybe running on a virtual machine on the original
backend). It wouldn't be configured as a slave backend. You would have to
use nuvexport to transfer the recordings to the second backend then
transcode the recordings down to a resolution the xbox can handle. The xbox
would only interface with the virtual machine backend.

Not easily possible with current Myth, but something that is on my TODO
list and that I've made a quick proof of concept of already. I'm looking
into extending Myth to support the concept of multiple (independent) files
per "recording", so you could have the original HD version for watching
on your HD frontend and a transcoded copy for watching on your Xbox or any
other slower frontend that wasn't HD capable. These would be tied to the
same recording entry. My current proof of concept code pops up a box
asking which version you want to play, but the actual implementation could
prompt or automatically decide based on the file description in the DB
(HD vs transcoded, etc.) or possibly even based on the contents in the
future.

My current test code adds a 'recordedfile' table. Adding another copy
of the recording is as simple as inserting a new record into that table
and it automatically appears on the popup menu when you try to play the
recording. That's the easy part. Handling these alternate files in
places like the AutoExpirer are a bit more difficult.

I had mentioned this a couple of months back, but was met with
silence. I'm happy to see you've got it in the works! I would be
thrilled to keep full-res HD for watching just on my living room
front end and make everyone else watch a transcoded version that
doesn't bring their machines to a hault and tie up my network.

I must have missed it or either I replied with a link to the script
I posted a while back that let you keep the transcoded copy as
another recording in Myth by duplicating all the recording info
and offsetting the time by a second. Total hack, but I think
it accomplished what someone was looking for when I posted it.

Yeah, it will be a long time before all my frontends are HD
capable so I'd like the same thing.

How far of do you think this kind of thing is? MythTV .21? or later?

i think this is really needed being the high hardware demands of HD and all the frontends that cant hadle the load. Also many people only have one HDTV and use their older SD TV's in other rooms its a waste of hardware to spend $$ to decode HD when your using that SD tv.

Since I think 0.21 is a ways off, I can probably say that you'll see it
in SVN before 0.21 is out. Right now, it is pretty high on my TODO list
so I will be working on it as I have time.

That's another reason, I have frontends that I doubt I'll ever upgrade
to make them HD capable, but I still want to be able to watch a transcoded
copy of an HD show on them.
