A couple of notes about the implementation: 1. I added functions for updating MOVStreamContext::current_sample - inc / dec / set, all changes to this field are done using these functions. In addition to applying the change to current_sample, these functions keep track of the frame index in a new field called current_index. 2. mov_fix_index initializes a new array 'index_ranges' with the start/end values of each edit. The array is null terminated (end = 0). 3. A new field called auxiliary_info_index keeps track of the index of the frame whose auxiliary info matches auxiliary_info_pos - these 2 fields are always updated together. 4. In cenc_filter, if the auxiliary info index does not match the current frame index, the auxiliary info position is recalculated, using the code that was added previously for supporting seek.
