@ -30,11 +30,39 @@ Who: Adrian Bunk <bunk@stusta.de>
|

---------------------------
|
||||
|
||||
What: raw1394: requests of type RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN
|
||||
When: November 2006
|
||||
Why: Deprecated in favour of the new ioctl-based rawiso interface, which is
|
||||
more efficient. You should really be using libraw1394 for raw1394
|
||||
access anyway.
|
||||
Who: Jody McIntyre <scjody@modernduck.com>
|
||||
When: June 2007
|
||||
Why: Deprecated in favour of the more efficient and robust rawiso interface.
|
||||
Affected are applications which use the deprecated part of libraw1394
|
||||
(raw1394_iso_write, raw1394_start_iso_write, raw1394_start_iso_rcv,
|
||||
raw1394_stop_iso_rcv) or bypass libraw1394.

|
||||
---------------------------
|
||||
|
||||
What: dv1394 driver (CONFIG_IEEE1394_DV1394)
|
||||
When: June 2007
|
||||
Why: Replaced by raw1394 + userspace libraries, notably libiec61883. This
|
||||
shift of application support has been indicated on www.linux1394.org
|
||||
and developers' mailinglists for quite some time. Major applications
|
||||
have been converted, with the exception of ffmpeg and hence xine.
|
||||
Piped output of dvgrab2 is a partial equivalent to dv1394.

|
||||
What: ieee1394 core's unused exports (CONFIG_IEEE1394_EXPORT_FULL_API)
|
||||
When: January 2007
|
||||
Why: There are no projects known to use these exported symbols, except
|
||||
dfg1394 (uses one symbol whose functionality is core-internal now).

When: January 2007
