I had some time to set up a new Pi3 frontend this weekend. I basically
replicated the same experience from when I tried a little more than a year
ago. 1080i was still not usable for me. It seems like others have this
working.. what am I missing?
My experience was:
1. Spent a lot of time debugging. This is a recurring theme in my long
experience with MythTV. I got random frontend hangs, which I thought were
related to video decoding. But, after much debugging got it down to the
"query_cache" settings in MySQL. Once I disabled that the frontend became
reliable.
2. US Broadcast MPEG2 @ 720P works great.
3. US Broadcast MPEG2 @1080i does not work well. I get video playback,
but with frequent audio hiccups and some video hiccups. The default
de-interlacer setting of 'Advanced (HW)' was quite bad. When I changed it
to "Fast (hw)' it worked much better -- but still had audio/video hiccups.
MythTV version: 0.28 (up-to-date frontend and backend)
Video Settings: OpenMax normal, Decoder: Openmax, renderer: openmax, OSD
Renderer: OpenGL; Primary deinterlacer: Fast(HW)
MPEG2 license enabled: verified by command line and CPU load during playback
Output: HDMI @ 1080P on 4K TV
Any tips on reliable 1080i MPEG2 playback?
