New install video not playing

Hi, i have installed a new instance tv1.gomntu.space when i try to upload a video ist working fine but i cannot play the video and the preview is also not shown.
I have installed ffmpeg version 4.4-1ubuntu0~18.04.sav0.1

what can i do ?
regards Steffen

Hello,

PeerTube is not compatible with ffmpeg 4.4. Please install ffmpeg 4.3 or use the latest master branch build

ok i have installed ffmpeg 4.3 via this guide How to Install FFmpeg 4.3 in via PPA Ubuntu 18.04, 16.04 | UbuntuHandbook

but is still not working, the videos are processing in the log .

Failed to load resource: the server responded with a status of 404 ()
https://tv1.gomntu.space/static/streaming-playlists/hls/6eff62cb-fbd8-42a4-87b9-ac7fb77e8b7f/segments-sha256.json

i can see the files in the folder /streaming-playlists/hls/6eff…

the storage is on a nfs mount, i have changed the storage path in the config, so the videos are saved on the nfs mount also the previews

now i have change the line #140 in nginx config
from:
#root /var/www/peertube/storage;
to:
root /mynfsmount; # in this mount are the folders avatars,cache,plugins,preview …

Thanks @Chocobozzz i had same issue for weeks , when i upgraded my ffmpeg to version 3.4 .everything seems to work .Thanks alot

I’m having the same issue but I’m using a docker latest version.
