DCCP for gstreamer-1.0

[Jiaqi Gao]

Hi,

I'm trying to build a simple streaming pipeline over DCCP to do some
experiment and measurement. But I noticed the DCCP plugin is unavailable in
the Gstreamer-1.0 version. The old DCCP plugin code is still available in
1.10 version, but only works for Gstreamer 0.10.

Does there any unofficial version available? Or can I just modify based on
the TCP plugin?

I also tried using Gstreamer 0.10, and try to transfer file using following
command:

Client:
gst-launch-0.10 filesrc location=~/video.mpg ! dccpclientsink port=8000
host=x.x.x.x

Server:
gst-launch-0.10 dccpserversrc port=8000 ! filesink location=~/video.mpg

This gave me 0 loss and the file is complete. But when I tried doing
something else, things are different:

Client:
gst-launch-0.10 filesrc location=~/video.mpg ! dccpclientsink port=8000
host=x.x.x.x

Server:
gst-launch-0.10 dccpserversrc port=8000 ! decodebin ! ffmpegcolorspace !
pngenc snapshot=false ! multifilesink location=~/frame%05.jpg

There are 177 frames in the video.mpg, I can only extract around 150 frames
out. And the result differs between each execution.

The problem doesn't exist just change DCCP to TCP. The experiment
environment is two servers under the same subnet.

Does anyone has idea on why this happens and has any solution? Can I solve
it by switching to Gstreamer 1.0?

Thanks,

Jiaqi
