The logic in mov_seek_fragment for matching track_ids to AVStream ids is almost certainly wrong, and should be corrected (by someone who knows more about the relevant structures) before this is merged. Fixes trac #3842 --- libavformat/isom.h | 1 + libavformat/mov.c | 181

Also disable the mmx/iwht optimization when the bitexact flag is set. With synthetically coded coefficients (i.e. these that lead to a residual well outside the [-255,255] range), our optimizations will overflow. It doesn't make sense to fix the overflows, since they can only occur on synthetic
