From 78eeb6636e3e8297a9d739c8dd1196f57f91a085 Mon Sep 17 00:00:00 2001 From: David Schleef Date: Sun, 13 Sep 2009 12:30:34 -0700 Subject: [PATCH] multifilesink: Add next-file property Add a property to allow control over what event causes a file to finish being written and a new file start. The default is the same as before -- each buffer causes a new file to be written. Added is a case where buffers are written to the same file until a discontinuity in the stream. --- gst/multifile/gstmultifilesink.c | 141 ++++++++++++++++++++++++++++++++++----- gst/multifile/gstmultifilesink.h | 7 ++ 2 files changed, 131 insertions(+), 17 deletions(-) diff --git a/gst/multifile/gstmultifilesink.c b/gst/multifile/gstmultifilesink.c index f8c604a..e11e709 100644 --- a/gst/multifile/gstmultifilesink.c +++ b/gst/multifile/gstmultifilesink.c @@ -110,6 +110,7 @@ # include "config.h" #endif #include +#include #include "gstmultifilesink.h" static GstStaticPadTemplate sinktemplate = GST_STATIC_PAD_TEMPLATE ("sink", @@ -129,6 +130,7 @@ GST_ELEMENT_DETAILS ("Multi-File Sink", #define DEFAULT_LOCATION "%05d" #define DEFAULT_INDEX 0 #define DEFAULT_POST_MESSAGES FALSE +#define DEFAULT_NEXT_FILE GST_MULTI_FILE_SINK_NEXT_BUFFER enum { @@ -136,6 +138,7 @@ enum PROP_LOCATION, PROP_INDEX, PROP_POST_MESSAGES, + PROP_NEXT_FILE, PROP_LAST };
