Stefan is correct that gcc auto-vectorization will not give any significant gain
in acceleration of the video encoders. Moreover, if you are thinking of encoding
on mobile devices, you need to spend several months writing/optimizing encoder
using NEON, and end of day you might end up with something which is not realtime
encoding. FFMPEG's usefulness is limited to Desktop PCs. You may contact some
codec company which provides encoder on iPhone or Android. That should help.
