[FFmpeg-devel] [PATCHv2 2/2] avcodec/vda_h264_dec: use multichar literal portably

[Ganesh Ajjanagadde]

Multichar literals are implementation defined, and thus trigger -Wmultichar:
http://fate.ffmpeg.org/log.cgi?time=20150918202532&log=compile&slot=x86_64-darwin-gcc-5.
This patch uses AV_RB32 to silence such warnings.
