seg fault on 64 bit ARM

Thu Jan 19 17:38:51 UTC 2017

Hello,

I am trying to run a gst-launch pipeline on 64 bit ARM architecture. The only warning I see is from libde265dec. "dec.c:860:gst_libde265_dec_handle_frame:<libde265dec0>[00m warning: Cannot run decoder multi-threaded because stream does not support WPP (code=1000)"

Can you tell what the problem is from the following debug output?

The pipeline:

gst-launch-1.0 -v -e  --gst-debug-level=3  qtmux name=m ! filesink location=uhd1280x720swenc.mp4 filesrc location=uhd.trp ! tsdemux name=dem dem. ! queue ! h265parse ! libde265dec ! videoscale ! 'video/x-raw, width=(int)1280, height=(int)720, format=(string)I420' ! x264enc dct8x8=true ! m. dem. ! queue ! avdec_aac ! audioconvert ! voaacenc ! m. 

The output:
