Original commit message from CVS: 2005-08-16 Andy Wingo <wingo@pobox.com> * ext/raw1394/gstdv1394src.c (gst_dv1394src_iso_receive): Note license info in the source code -- was only in the commit log before. * ext/dv/gstdvdec.h: * ext/dv/gstdvdec.c: Only decodes systemstream=FALSE dv video -- old pipelines using dvdec should probably have a dvdemux first. * ext/dv/gstdvdemux.h: * ext/dv/gstdvdemux.c: Split out from dvdec, chunks the incoming systemstream=TRUE data into frames, sets caps data, and spits out PCM audio in addition to systemstream=FALSE video frames. Operates in chain mode only for now; should make a getrange version as well. * ext/dv/gstdv.c: New file, registers the libgstdv plugin. * ext/dv/Makefile.am: Library name changed to libgstdv. Split dvdec into dvdemux and dvdec.

* ext/raw1394/gstdv1394src.c (gst_dv1394src_iso_receive): Note
|
||||||
|
license info in the source code -- was only in the commit log
|
||||||
|
before.
|
||||||
|
|
||||||
|
* ext/dv/gstdvdec.h:
|
||||||
|
* ext/dv/gstdvdec.c: Only decodes systemstream=FALSE dv video --
|
||||||
|
old pipelines using dvdec should probably have a dvdemux first.
|
||||||
|
|
||||||
|
* ext/dv/gstdvdemux.h:
|
||||||
|
* ext/dv/gstdvdemux.c: Split out from dvdec, chunks the incoming
|
||||||
|
systemstream=TRUE data into frames, sets caps data, and spits out
|
||||||
|
PCM audio in addition to systemstream=FALSE video frames. Operates
|
||||||
|
in chain mode only for now; should make a getrange version as
|
||||||
|
well.
|
||||||
|
|
||||||
|
* ext/dv/gstdv.c: New file, registers the libgstdv plugin.
|
||||||
|
|
||||||
|
* ext/dv/Makefile.am: Library name changed to libgstdv. Split
|
||||||
|
dvdec into dvdemux and dvdec.
