Platform: NVIDIA Shield TV 2019 model (the tube)
-
MythTV version: v31.0fixes

Package version: mythfrontend-20200716-arm-v31.0-79-g89d1991ef2.apk

Component: mythfrontend player
What steps will reproduce the bug?
On my 2017 Shield TV I have installed: mythfrontend-20190724-arm64-v31-Pre-539...apk
On a new 2019 Shield TV (Tube): mythfrontend-20200716-arm-v31.0-79-g89d1991ef2.apk
The 20190724-arm64-v31-Pre-539 works fine.
The new 20200716-arm-v31.0-79 has problems as follows. When seeking:
The audio does not mute when seeking, as it does on 20190724-arm64-v31-Pre-539.
The audio sync gets messed up when seeking, and causes the video to play double speed and without audio.
I did notice the AVSync2 menu option is missing from the Settings->Playback menus on 20200716-arm-v31.0-79, and I do have it set on the 20190724-arm64-v31-Pre-539 version.
Onn the Shield Tube, the leanback-frontend plays and seeks without error.
How often does it reproduce? Is there a required condition?
Randomly when seeking forward and/or backward. Occasionally, it kills the frontend completely and returns to android.
What is the expected behaviour?
To have it work like id does in mythfrontend-20190724-arm64-v31-Pre-539...apk
It works flawlessly in that release. I would install Pre-539 on the 2019 Tube Shield, but the Tube is a 32-bit version of android and requires a 32 bit mythfrontend, which I could not find in a Pre-539 release.
Something that changed from mythfrontend-20190724-arm64-v31-Pre-539...apk to mythfrontend-20200716-arm-v31.0-79-g89d1991ef2.apk seems to be the cause.
So I hope a fix results in the following:
- mutes audio while seeking (without little audio blips between each seek)
- resumes playing smoothly and without muted speedup or crashing
What do you see instead?
Audio gets out of sync with video between pressing forward/backward keys and, often, when playback resumes, the audio is muted and the playback speed is 2X (or so) fast. I have to exit playback and resume playback to recover. Sometimes, mythfrontend dies.
Additional information
jpilk suggested:
Most of the a/v sync issues in the new v31 playback code seem to have been related to the choice of deinterlacer. Perhaps this affects the Shield too.
I have tried all combinations of deinterlacer available in the menus, but to no avail.
