[gst-devel] Transform variable in constant framerate

[Armando Taffarel Neto]

Hi!

I think the problem is that videorate is discarding the rfbsrc frames.
See this (gstreamer debug):

0:00:01.621653000 12058 0x813b838 WARN             videorate
gstvideorate.c:722:gst_video_rate_chain:<videorate0> Got buffer with
GST_CLOCK_TIME_NONE timestamp, discarding it
0:00:01.629480000 12058 0x813b838 WARN             videorate
gstvideorate.c:722:gst_video_rate_chain:<videorate0> Got buffer with
GST_CLOCK_TIME_NONE timestamp, discarding it
0:00:01.635486000 12058 0x813b838 WARN             videorate
gstvideorate.c:722:gst_video_rate_chain:<videorate0> Got buffer with
GST_CLOCK_TIME_NONE timestamp, discarding it
0:00:01.646278000 12058 0x813b838 WARN             videorate
gstvideorate.c:722:gst_video_rate_chain:<videorate0> Got buffer with
GST_CLOCK_TIME_NONE timestamp, discarding it



The patch below seems to solve the problem:

cvs diff: Diffing gst/librfb
Index: gst/librfb/gstrfbsrc.c
===================================================================
RCS file: /cvs/gstreamer/gst-plugins-bad/gst/librfb/gstrfbsrc.c,v
retrieving revision 1.18
diff -r1.18 gstrfbsrc.c
398a399,400
> //  GST_BUFFER_TIMESTAMP (*outbuf) = gst_clock_get_time
(GST_ELEMENT_CLOCK (src)) - GST_ELEMENT_CAST (src)->base_time;
> 


Is this the correct way?


Hug!
