Malloc Check Failed core dump on Qnx/armv7le

Postby Melody » Tue Sep 05, 2017 6:35 am

I am suffering from a core dump when I run ffmpeg on qnx6.5/armv7le. I just want to modify a resolutiion of the input vedio.
It occurs occasionally.

Here is the command:

#ffmpeg -i input.mp4 -y -sn -an -c:v mpeg4 -r 25 -b:v 1000k -vf scale=-1:338 output.mp4

console output:

Malloc Check Failed: :/builds/workspace/PSP_kernel-libc-nvidia_brCustom_be650SP1/svn/lib/c/alloc/dlist.c:1171
Abort (core dumped)

report log:

Please show the complete console output from your command. Use the code button to format it so it's easier to read due to my laziness threshold.
Get an answer more quickly by providing your actual ffmpeg command and the complete console output. Use the code button to format your command and output or your question will be ignored.
