Bug#831909: gstreamer coredumps when playing wavs since the libavcodec upgrade

[Carl Eugen Hoyos]

Thank you for the backtrace!

Could you check if removing some or all entries from 
vaapi_encode_h264_defaults in libavcodec/vaapi_encode_h264.c 
fixes the issue? I was unable to quickly find the vaapi 
source file containing the option strings and I don't 
have a cpu with vaapi capabilities.

Thank you, Carl Eugen
