There are many problems of current qsv trellis option: 1. Duplicated with AVCodecContext definition 2. MFX_TRELLIS_XXX is introduced by MSDK API 1.17 Currently Without MSDK API checking thus may cause compilation issue. 3. user is inclined to enable trellis when set "-trellis 1", but actually it is to disable since MFX_TRELLIS_OFF is equal to 1. 4. It is too complex for user to enable trellis for every frame(I/P/B). Just simply remove the private option, and switch to the AVCodecContext definition. Compatibility should not a big problem (except can't exact map) since the option name is same as AVCodecContext.
