maybe but its implementation is unacceptable (i will kill whoever applies it)
it hacks the demxuer to linearly read O(n) style until the requested timestamp

1. this can be done generically for all demuxers at lavf core level
2. as packets do have timestamps and lots of redundancy O(log n) seeking
   is possible
