I have three general classes of devices I run Emby on:
​-Windows PCs, they would prefer MPEG2

-Amlogic S905/X, they would prefer MPEG4 "heavy" "mobile"

-Surface 2 & smartphones, they would prefer MPEG4 "mobile"

 

There's two situations:

 

1) Live TV: I assume Emby can request a specific profile from the HDHomeRun EXTEND and I also assume this isn't being done.  If it is being done, then I get the impression it is broken because the default profile set in each EXTEND impacts the streams that are played from it.  If it isn't automatically figuring this out, I'd like to be able to set it in Emby Server where Emby Theater requests MPEG2 and everything else gets MPEG4 "mobile."  Is this possible now?  It is possible to add?  Is it something that will be added?

 

2) Recordings: This is where things get iffy because Emby Server itself isn't the destination where the video will be consumed.  I think the best solution is to be able to select a transcoding profile on a per recording or series basis.  For example, I know some series only get watched on the Windows computers so it would recorded as MPEG2.  I know  series may be watched on tablets or Amlogic boxes so it would be recorded as MPEG2 "mobile."  Then there is sports events of all kinds need to be recorded as MPEG2 or MPEG4 "heavy" because MPEG4 "mobile" looks like crap. Is this possible now?  It is possible to add?  Is it something that will be added?

 

HDHomeRun EXTEND are powerful little devices but options in Emby appear to prevent them from being used optimally.

 

 

Edit: Apparently MPEG4 "heavy" is too much for the Amlogic 905/X devices.  Here is what MPC-HC got off the recording:

Video: MPEG4 Video (H264) 1920x1080 29.97fps [V: h264 high L4.0, yuv420p, 1920x1080]
Audio: Dolby AC3 48000Hz stereo 384kbps [A: English [eng] (ac3, 48000 Hz, stereo, 384 kb/s)]

Here's an MPEG4 "mobile":

Video: MPEG4 Video (H264) 1280x720 29.97fps [V: h264 high L4.0, yuv420p, 1280x720]
Audio: Dolby AC3 48000Hz 6ch 448kbps [A: English [eng] (ac3, 48000 Hz, 5.1, 448 kb/s)]

That is of a football game which would definitely be at least 1080i.  It appears "heavy" doesn't change resolution where "mobile" does.

It makes the decision on the fly based on the requirements requested by the emby app. In order to maximize direct play, the mobile apps do not care about resolution unless there are device specific requirements. Bitrate requested is the most important factor so if the heavy stream fits into the requested bitrate then that's what you get.
