We have just released Plex for Android 8.0.0.which introduces an app setting to disable transcoding on Amazon Fire for interlaced video
See release note:
- [TV] Live TV: Amazon Fire TV Stick 4k users can now disable transcode of interlaced streams.
The transcoding was introduced to circumvent the Amazon Fire 4k TV issue covered by this: FTV Stick 4K interlaced video playback leads to media player crash · Issue #94 · amzn/exoplayer-amazon-port · GitHub
Unfortunately whilst the transcoding fixed the problem for some users, other users especially ones with HD Homerun that does its own transcoding had issues with this change. So now we have a user setting to disable this transcoding if it is causing a problem
The transcoding and the related setting is temporary until the underlying issue is fixed by Amazon
