HDHomeRun Extend to avoid interlace issues

[sfatula 207]

So, the thought (finally) occurred to me. I have a duo and a quatro. If I replace the duo with the HdHomeRun Extend, and only used it for interlaced channels, I could set the profile (hopefullly) to send only progressive deinterlaced content to Emby for recording purposes, right? (not interested in live, just speaking of DVR recordings)

 

Which then avoids many hassles and limitations of Emby right now. Please do not ask about that comment, the question is, am I correct that using an Extend, I can record progressive to Emby?

 

Any issues or limitations with the extend for antenna recordings?

 

Or, does Emby still not support or respect the transcoding settings in the Extend?

Yes you could do that. Or you could also use the media convert feature in emby after recordings have completed.

Which Extend Transcode profile provides the highest quality deinterlaced content?

[Luke 42083]

The server picks the profile based on the quality requested by the Emby app that is playing.

@@Luke,  I thought this thread was about having the Extend  "to send only progressive deinterlaced content to Emby for recording purposes,"

 

So again  what is the transcode profile on the HDHR Extend  that will only send deinterlaced content from the tuner to Emby?

[Luke 42083]

I think any of them except for heavy, but Emby doesn't use your HDHR setting. It picks a value internally and then tells the HDHR to use that.

 

It picks based on whichever quality level is closest to what is being requested by the Emby app that is playing. It is always possible to expand on this and provide you with more control, but that is what it currently does today.

Thanks for the explanation Luke.  That explains why it seems to me I am not getting compression from the Extend regardless of my Extend settings.

 

I gotta sat it is not intuative when the interface for the tuner setup in Emby says:  

    "Allow hardware transcoding If enabled, allow the tuner to transcode streams on the fly. This may help reduce transcoding required by Emby Server.

But then Emby will choose to ignore the transcode settings from the tuner.  That just doesn't make sense to me.

 

OK, well the more control would be good.  Allowing us to choose what HDHR Extend profile we want.  Or just a checkbox that says something to the effect of   "Always use Transcode settings from tuner."

 

Regards.

Yes I think that makes sense. Thanks for the feedback.

Yeah, so, convert would convert all my media in a folder, didn't want that. And I dpon't want to manually pick them either. I only need interlaced content deinterlaced.

 

So, a second thought is writing a post recording script to simply yadif if the video width is 1920 (1080i). That way, only interlaced content is affected and therefore, I can leave Apple TV client on full quality since I don't have to worry about interlaced any more.

I wasn't aware that they extend deinterlaced anything. I thought it transcoded without deinterlacing.

[Mike-G 16]

I realize the discussion was about deinterlacing, so sorry if this is a bit off-topic (but it seems very much related)......

 

Is there any way to configure Emby and/or the Extend so Emby records from the Extend already transcoded into H.264 (that's why I got the model with built-in hw transcoding)?  It seems that even though my Extend is set to hardware transcode, the files Emby is recording seem to be mpeg2 (unless I'm reading the MediaInfo output wrong)? Maybe I've done something stupid and just need to configure something differently?

The HDhomerun document: here

https://www.silicondust.com/hdhomerun/hdhomerun_http_development.pdf

 

Indicate heavy as  "interlacing as the original stream"   and others as progressive.

 

 

The kicker here is that we have learned from Luke  that emby ignores the transcode settings on the HDhomerun  and requests the profile that best fits the client and your emby settings.

 

@luke 

What if there is no client/app  involved?   What if it is a scheduled recording from the server?   In those scheduled recording cases what does Emby request from the HDhomerun?

Thanks for that clarification, I never knew that.  Have never seen that document.  I purchased the Extend at pre-order, because I wanted the transcoding, so I could watch on a tablet.  That was years ago, and haven't used the transcoding function in years.

[Luke 42083]

When no client is involved it requests the original stream.
