The following series of patches fix cross-compilation linking errors
in the openHEVC code for ARM targets. The patches aim at resolving
undefined references during linking while generating hevc_sdl2 execu-
table which links to libLibOpenHevcWrapper.so library as a result of
missing function definations from ffmpeg libavcodec. The corresponding
files have been merged into existing code to resolve linking time
dependencies.
I request the maintainers to please check the patch and verify that it
doesn't breaks any existing functionality or causes build instability.
