Stuttering playback on Intel Bay Trail over NFS/SMB

Hello

Did an update after a long while from a previous < 8 version to git pull from yesterday as I hoped it would fix some crashes on the Minix Z64A platform...

When playing back a file over NFS share I see after few minutes in the logs:

10:53:08.293 T:140132057757440 DEBUG: CVideoPlayerVideo::CalcDropRequirement - hurry: 1

Playing locally from uSD card or USB is fine...

Has anything been changed in networking since version >= 8.0 ?

With previous 7.xx version playback was flawless with Bluray ISO rips....

That is not a log, that is only a very tiny snippet of a log.

We ask for the kodi.log, the whole kodi.log, and nothing but the kodi.log, so help us Kodi.

Here you go:

LFYL

The scrambled chars at the end are when the system freezes totally during playback...

And yes...the NFS share can delivery > 500MBits/sec....

Can't be network performance on the device itself...

When mounting the NFS share directly and doing a "dd" I get:

LibreELEC:~ # dd if=/var/media/movies/animation/Despicable.me.mkv of=/dev/null

38298419+1 records in

38298419+1 records out

Seems definitively something broken with kodi's NFS support...

When playing the same movie from a locally mounted NFS share it plays just fine...

Just few of those messages here and there:
