x265 segmentation fault???

[fifer55]

Hello,

I am currently running:
yuv [info]: 3840x1714 fps 24000/1001 i420p10 frames 0 - 340 of 341
x265 [info]: HEVC encoder version 1.5

x265 [info]: Internal bit depth : 10
x265 [info]: CTU size / RQT depth inter / intra : 64 / 1 / 1

Using the following source (Tears of Steel - "4K" rendered):
http://ftp.nluug.nl/pub/graphics/blender/demo/movies/ToS/

When I try to run my commands, I get the following error:
Segmentation fault: 11

No other errors.

I have tried to run in 8b mode, tried to reduce the number of switches and make bare-bones but nothing seems to work.

Any ideas would be appreciated.

Compiling x265 in debug mode and posting a crashdump / backtrace would be a first step :) .

Also may we have your tested command line?

Hello All,

After thinking about it, I just removed any/all traces of ffmpeg, its libraries and x265, recompiled in high bit depth mode and it is working now.

Also, updated to the latest version of x265:

Thanks all!

Now I just have to deal with the VBV underflow errors:
