Tvheadend

Don't know exactly what the problem could be... but better to describe and experts will tell.

Since advanced encode options of nvenc are yet to be implemented on tvheadend i been using or spawn profile in tvheadend or transcoding 100% outside tvheadend.

So if i run ffmpeg outside tvheadend and with more than 7-10 streams playing simultaneous pulling from tvheadend after a few seconds i start getting this messages on tvheadend:

2018-02-10 23:15:18.108 tbl-pass: pass-eit: -: invalid checksum (len 3825, errors 2)

2018-02-10 23:16:06.976 tbl-pass: pass-eit: -: invalid checksum (len 543, errors 2)

note that i don't have any problem on source (satipaxe with 0 cc errors).

as soon as this messages begin on tvheadend the ffmpeg output become a mess full of macroblocks and freezing.

This is all being done in same machine and cpu doesn't even pass the 30%.

I tried exactly the same amount of streams with spawn profile and no problems with output... however tvheadend with this amount of streams begin to be unresponsive.

So in my last try i tried the same amount of streams but split between outside command line and spawn... same problem... this is the output of spawn:

this is exactly the same errors i also see in ffmpeg running outside.

A small apart: when i use tvheadend stream as source of ffmpeg between the play command and to start seing image it takes around 5-8secs. This is probably related with this messages:
