CVSROOT: /sources/libcvd
Module name: libcvd
Changes by: Georg Klein <georgklein> 08/07/14 00:03:55
Added files:
cvd/Linux : dvbuffer3.h
cvd_src/Linux : dvbuffer3_dc1394v1.cc dvbuffer3_dc1394v2.cc
Log message:
Added DVBuffer3, which is yet another DC1394 buffer.
The interface for this one does abstracts away the libdc1394 headers.
There are two implementaions: One is new and uses libdc1394v2; this
supports a large range of DC1394 fixed-modes and frame-rates. The other
implementation provide compatibility for libdc1394v1, and this one just
wraps (rather messily) the existing DVBuffer2 code.
n.b. No updates to configure scripts or makefile yet.
