Original commit message from CVS:
Totally new bytestream code, works well for non-spannable buffers, there's
some refcounting problem still when used with filesrc (spannable buffers).
To test, set the bytesperread or blocksize parameter of disksrc or filesrc
(resp), attach it to gstbstest (in this dir) with byte_size and count
parameters set, and pipe to fakesink or something. gstbstest will exit(1)
after count buffers have been read from the bytestream.
disksrc location= bytesperread= ! gstbstest byte_size= count= ! fakesink
