Mythtv-Leanfront running on Sony TV
Hi,

I installed leanfront on my Sony TV a couple of days ago. It works well and
a big thanks to Peter Bennett for a great solution to today's version of
the original problem that MythTV was intended to solve - integration.
Finally I can throw away my old and buggy Harmony remote and just use the
Sony remote...

I've notice a couple of minor things though, and I was wondering if Peter
or someone else could advise/comment:

Firstly, pretty much all our FTA TV channels are interlaced, either 1080i,
or lower resolution, at 25Hz (Australia). I've noticed that leanfront
complains that there is no suitable refresh rate for frame rates of 25Hz.
And 23.98Hz content too for that matter. However, the playback appears very
smooth, so I'm wondering what frame rate leanfront is using?

Secondly, there are a few formats which don't work for me. This is not a
big deal, but I'd be interested to know if this is a case of "no can do" or
just "our priorities meant we didn't implement that" (or something else).
These include:
* WMV VC1 1080p @ 23.976Hz (no video but the audio played fine - both
TrueHD and DTS files).
* H265 MPEGH HEVC 2160p 23.976 Hz (video and audio played but was a bit
choppy).
* H264 MPEG4 AVC 1080p 29.97Hz (no video and no audio - either TrueHD or
E-AC3).

These formats all worked fine on the MythTV Frontend connected to the same
TV. Note that the majority of 4K files I've tried work just fine.

Thirdly, a feature request, if Peter is ever in the mood: Can we have a
function to display playback data like the Frontend does?

My setup:
TV: Sony A80J 4K OLED
OS: Android TV 10
Kernel version: 4.19.75
Frontend/Backend MythTV version: 32-fixes
Frontend/Backend OS: Ubuntu 22.04
Frontend/Backend HW: Asus Prime B660M-K D4 with i5-12400 using onboard
(Intel) 4K video (HDMI).

Thanks again,

Cheers,
Justin.

Did you try:

Frame Rate Synchronization.
If you are playing a video or recording that was recorded at a different
frame rate from the default for your android device, motion may appear
jerky. Frame Rate Synchronization fixes this by changing the refresh rate
of your TV to match the frame rate of the video. Select "Match original
frame rate" in the playback settings. With Amazon Fire TV Stick you also
need to enable the "Match original frame rate" setting in the Fire TV
settings.

Peter's solution works for me:

http://lists.mythtv.org/pipermail/mythtv-users/2022-December/410836.html

I (Peter) have the same thing on a fire tv (i.e. tv with fire built in,
not a separate fire stick). There seems no way to change refresh rates
and the android system is not reporting a list of available refresh
rates to the application.

Solution: disable "match original framerate" under "Playback" in the
Settings.

I installed leanfront (Perth) on a firetv stick and I have not encounted *any* framerate complaints or any ‘won’t plays’
We get no HVEC (7, 9, 10, ABC, SBS) everything I’ve looked at is 25Hz with ABC, SBS doing around 4000 Kbs and the commercial chans arond 2Mb/s. During the Doco on coral-spawing ABC upped the data rate to high 4000s
I’ve got some samples of jellyfish clips and 4K upto 100mb HVEC looks beautifull beyond that the LAN causes a whiring circle

Disable "match original framerate" in settings. It does not work with
Android TVs and does not seem to be necessary with Android TVs.

The video formats supported are dependent on the TV decoder
implementation. leanfront does not use software decoding for video.
Audio plays with either the TV decoder or with software decoding.

VC1: Likely not supported by the TV decoder.

H265: It looks like the TV decoder is under-powered.

H254: Likely the file is formatted in a way that is not supported. In
particular, AVI files are not supported. You can quickly and easily
convert files that are in an unsupported format to mkv using mkvmerge.

Please open an issue in github for the feature request.
