| <p>Attempt to seek out of the buffered range. If supported, this |
| should cause a waiting and seeking event to be fired for each seek. |
| This test makes assumptions on the size of the input file, the bitrate |
| of delivery, and the duration of the file. |
| </p> |
| <p> |
| Source is assumed to be about 188k with a uniform bitrate, > 4 |
| seconds in length, and served at 25kb/s. This should make seeking one |
| second ahead every 200ms always leave the buffered region. |
