Original commit message from CVS:
New bytestream fileio style api has landed, along with some minor fixes:
- implement gst_bytestream_tell
- prevent buffers from being gobbled after a seek
Original commit message from CVS:
Added gst_bytestream_get_timestamp() call to get timestamp of data at
the front of the stream. If no data in stream, loads 1 byte to get a
new buffer and uses its timestamp.
Does nothing to handle readers that try to read data lengths that span
buffers with multiple timestamps.
_get_timestamp() now used when creating new buffers.
