live stream encoding problem

[Former user]

I am using ffmpeg 3.3 and x265 ver. 2.3 on debian 9 setup. I can encoding live dvbs SD streams without problem but When I try to encoding live dvbs HD streams FFmpeg stop a few seconds later I have tried with tvheadend and astra same result.

is this FFmpeg or x265 issue?

Sounds like something to do with ffmpeg or your system as between HD and SD, the only difference is in the amount of memory that is allocated. We've been able to use ffmpeg + x265 to encode hours of video without any problems.

Not able to reproduce in x265; seems like an ffmpeg issue.
