i’ve a strange issue with fire tv 4k max
server:lastest
player: latest
i’ve figured a problem with avi tv shows, all are in h264 avc codec. they all stutter/loose frames,
with some research i found that the combination of avi and avc codecs are not supported in fire tv, or I’m missing something?
is there a way to re encode all the tv shows in mpeg4 avi format without a pain?
You should just remux those to MKV. Not sure who thought putting AVC into an AVI container was a good idea but that’s duuuuumb. Won’t impact quality of the video and it’s fairly easy assuming mkvtoolnix accepts an AVI as an input file.
in the past i preferred avi container for better compatibility, and i always converted tv shows in avi without any issues, but recently i started having some issues on fire tv.
on the other side on apple tv4k those tv shows play well without any issues… so i’m thinking of converting them back to mkv as long i’ve more than 3k tv shows episodes coded in avc into avi container 
There are batch automation tools for remuxing that will likely help with that. Just start with whatever you are watching now. This also will give you the chance to properly label language tracks and subtitles if you have sidecar files now.
can you please tell me what software can do remux with more than 3000 files in subfolder ( every show with his own directory and season directory)?
i’ve tried mkvtoolnix and it work but can’t handle much files per time…
Mkvtoolnix itself can do this, but I don’t know if there is a graphical interface method. You might have to use the command-line. See here:

I tried using MKV Muxxing Batch GUI just now, since I use it for some automated remuxxing and while it can take the AVI files as input, it didn’t seem to successfully run with the ones I gave it, but my AVIs have WMV and MPEG2-based codec video in them. Not H.264. So that might have something to do with why it didn’t process things.
There’s plenty of video converter programs out there. You just need one that can read AVI files and has “copy” options for the audio and video streams. Most remuxxing I do is manually, one file at a time, in MKVToolnix’s GUI. So I can’t really be much help here finding a method of doing a large number of files in an automated fashion. MKVToolnix GUI works fine for a single file when I try here, but it doesn’t really have a batch mode where it picks the files itself to use for input.
You said you converted these yourself. Are you not able to use the same software you used before to move the audio and video streams back into MKV?
i’ve tried it ( yesterday i found it) but it doesn’t work very well…
so now i’m doing manually some file at time 
You can do this remux in VLC, which would let you set up a batch, but the MKV files it makes are screwed up in some way. They show up as being 248 hours long when I play them back on mpv. I tested one on my Fire Stick and it played back transcoded, but that might be from something in the format.
Very likely software out there to help with this.
nevermind… I used mkvtoolknix and add some file per time i used to convert all the stuffs
it was a long day ahahaha
