The reader ignores the size of the ASF data object and keeps on

The reader ignores the size of the ASF data object and keeps on
reading even beyond it.
Therefore if the ASF file includes an index object at its end, the
reader will treat the index like data, but of course will fail since
it thinks that the data is corrupted.
When reading an asf file with an index object, ffmpeg will
complain at the end of the file that it read an invalid header.
