avdec_h264 seg fault

[Gary Metalle]

Hi


I am getting a segmentation fault trying to use the avdec_h264 decoder in the libav plugin.


I am running on an ARM platform running Linux with kernel 4.14.78-mx6+ge692c3062368.

Gstreamer 1.14.4

LSB Version:    core-5.0-noarch:core-5.0-arm
Distributor ID: fslc-framebuffer
Description:    FSLC FrameBuffer 2.6
Release:        2.6
Codename:       thud


libavcodec     58. 18.100 / 58. 18.100?

If I use a Freescale implemented imxvpudec hardware decoder then it works fine (see below).


I appreciate the platform is very specific, I will speak to my boss on Monday who built the distribution and see if he can rebuild it. Just wanted to know if sort of issue anyone has seen or can recommend some further investigation.
