Delay in audio and image ratio in firestick 4k

[Randyou]

I have tried the vlc in firestick 4k and I see the problem that comments in this other thread and it has not been solved (https://forum.videolan.org/viewtopic.php?f=35&t=147533&p=497255&hilit=firestick#p497255) the image ratio deforms you. The question is that by downloading an older version 3.2.0. This is solved but to me only in 1080 videos as soon as it puts a video in 4k and it is deformed again.
Another incredible theme is the delay in the audio of all the videos of -350 ms you have to go video by video changing this. There is an option that says "Custom options LIBVLV" It lets you write a code I guess there will be something that can be put so that all videos have that delay of -350ms and not have to put one by one. I hope you solve the problem because it is undoubtedly the best player but for these details I am now using the PLEX that is perfect but I do not like its interface.
