suggestion for new feature ( seekable stream)

[publicocean0]

Now the buffer is appended with chunks so the stream is incremental.
This has limitations:
-song buffer can be big (above all in mobile device (my android phone is crashed for out of memory)or for long files)

• if multiple players are embedded in a html page( i think a facebook template example) the problem get more critical
  A more generic solution is to permit to append a chunk from a specific file offset:
• append call might add a parameter append(offset,buffer)
• the buffersize must be fixed (maybe configurable)
• player.buffered might be a object like {start:x , end:y} ,x<y. for defining a segment inside the time line.
  -demuxer seek(time) might return the file offset from where to upload the chunks (the upper limit could be handled automatically by demuxer (merging or skipping or replacing)) or seek(time) return a range (missing segment)

I use a similar logic for another decoder and it works
