Dear all,
I have a large collection of anime files with the bellow combination of codecs for audio and video. The thing is that playing from the web player works fine, but doing so from the Fire TV app and the Android app produces a weird problem: it play the first minute or so fine and afterwards buffers every second for a while, reproduces 1-2 seconds and then another 20ish seconds of buffering, making everything unwatchable. This does not happens tho if I use an external player or if I force transcodification by using mobile data. I think is a problem of the Plex player on those apps. I am a Plex Pass holder btw.

This only happens with this type of files with this specific combination of video/audio codecs but does not happens with anything else. Optimizing for TV and Mobile works fine but if I need to do this for my ENTIRE collection…
Can I have a hand on this?
Thanks

FIX?
Okay, I have find a solution that does not involve limiting the bandwith, kind of. Changing maximum level of H264 from 5.2 to 3.2 drops the BW use from crazy to normal as it forces it to transcode without dropping the quality.
