Help with dv1394src pipeline

[Ramiro Blanco]

Found the problem by running the pipeline with "GST_DEBUG=2"
I got:

0:00:00.161635749  5217  0x8af6bb0 WARN           basetransform
gstbasetransform.c:1304:gst_base_transform_setcaps:<audioconvert0>
transform could not transform audio/x-raw-int, rate=(int)48000,
depth=(int)16, width=(int)16, signed=(boolean)true, channels=(int)2,
endianness=(int)1234 in anything we support

I've added audioresample and some other tweaking and finally ended up with:

gst-launch-0.10  dv1394src ! queue ! dvdemux name=demux demux.video ! queue
! dvdec ! ffmpegcolorspace ! aspectratiocrop aspect-ratio=16/9 ! x264enc
pass=pass1 threads=0 bitrate=536 tune=zerolatency ! queue ! flvmux name=mux
demux.audio ! audio/x-raw-int !  queue  ! audioresample ! audioconvert !
lame ! audio/mpeg ! mux. mux. !
rtmpsink location='rtmp://x.x.x.x/live/cdn_live_1324358201415'

Which seems to work as expected.

Hope it helps someone.

Cheers!
