Live streaming starts but then fails with access denied

[TheFonz]

I am getting access denied on live streams but recordings seem to working
here is my config

Code:

docker run -d \
    --name nextpvr \
    --user root \
    --volume /root/config:/config \
    --volume /mnt/livetv:/recordings \
    --volume /mnt/livetv:/buffer \
    --restart unless-stopped \
    --publish 16891:16891/udp \
    --publish 8866:8866 \
    nextpvr/nextpvr_amd64:stable

I then get receiving data for a a tiny bit, sometimes get video+audio but for a max of about 10 seconds,  before a massive dump of the following error:

Code:

2025-05-13 00:23:51.528 [ERROR][29] Unexpected error writing to OutputSink: System.UnauthorizedAccessException: Access to the path '/buffer/live-Channel 9-1-2.ts' is denied.
---> System.IO.IOException: Permission denied
  --- End of inner exception stack trace ---
  at System.IO.RandomAccess.WriteAtOffset(SafeFileHandle handle, ReadOnlySpan`1 buffer, Int64 fileOffset)
  at System.IO.Strategies.BufferedFileStreamStrategy.WriteSpan(ReadOnlySpan`1 source, ArraySegment`1 arraySegment)
  at NShared.Writer.OutputSink.Write(Byte[] data, Int32 offset, Int32 length)

I even tried the buffer folder the same as the recording folder to no avail.
both the buffer & recording folders are the same SMB share.

I am running NextPVR on a docker LXC in proxmox.
I have confirmed the permissions and read+write access to the mnt to be working.

Any ideas would be appreciated!
Cheers,

Although you say you you confirmed the permissions, i will still be Linux permissions on /mnt/livetv or on the mount itself. You can likely confirm that by using /tmp instead of /mnt/livetv

Yep changing to /tmp works fine - however the drive for the nextpvr lxc is only 14gb and not networked in anyway, so trying to avoid that. I have followed a few tuts re lxc smb shares and permissions but something is still hinky.
When starting a live stream the ts file(s) get created, which proves read+write doesn't it??

[mvallevand]

That was was simply to show you you have a permission error. If you can write to the local file system maybe focus on smb and the server itself. Sorry I cant help further.
