sending svg picture over tcp lost alpha channel

[xxrici]

Hi All,

I've to send svg picture over tcp but I don't know why this causes lost of alpha channel.

when I try
gst-launch -vvv filesrc location=./srcimage.svg ! rsvgdec ! alphacolor ! pngenc ! filesink location=./target-image.png
I get right formed png image; for this reason I was thinking about command lines like
gst-launch -vvv filesrc location=./srcimage.svg ! rsvgdec ! alphacolor ! imagefreeze ! theoraenc ! oggmux ! tcpserversink
and
gst-launch tcpclientsrc host=localhost ! oggdemux ! theoradec ! alphacolor ! pngenc ! filesink location=./target-image.png.

Thanks to all in advance for every advices.

If you just want to send image to other end. I guess this would be sufficient.  

gst-launch  filesrc location=./media/image.svg ! rsvgdec ! alphacolor !  pngenc ! tcpserversink

gst-launch tcpclientsrc host=localhost !   filesink location=./target-image.png.

Thank you so much, but, with your pipelines, server don't wait for one or more clients, and it ends; infact the output is:
Impostazione della pipeline a PAUSED ...
La pipeline è in PREROLLING ...
La pipeline è in PREROLLED ...
Impostazione della pipeline a PLAYING ...
New clock: GstSystemClock
Ottenuto EOS dall'elemento «pipeline0».
Execution ended after 40125480 ns.
Impostazione della pipeline a PAUSED ...
Impostazione della pipeline a READY ...
Impostazione della pipeline a NULL ...
Esecuzione di free sulla pipeline...
....0,4 sec....
I've to transmit alpha channel and the compression (not necessarily theora) is not important, but desiderable...
please help me :D

Then use imagefreeze between alphacolor and pngenc.
