Subtract the calculated dts offset from the requested timestamp before seeking. This fixes an error "Error while filtering: Operation not permitted" observed with a short file which contains only one key frame and starts with negative timestamps. Then, av_index_search_timestamp() returns a valid negative timestamp, but mov_seek_stream bails out with AVERROR_INVALIDDATA. Fixes ticket #6139.
