Hi all.<br>
<br>
I have many TV streams (Mpeg2) in udp multicast.<br>
I want to have stream in H264+AAC in udp multicast with 3
resolutions: 1:1 (original),1:2,1:4. Now I do it with 3 processes of
gst-launch, but for optimization of CPU usage I think I can do it in
one process.<br>
After several tries I get 3 videos with 3 resolutions, but i can't
get audio for all threads, only for one.<br>
I'm using gstreamer 1.00+ version:<br>
$ gst-launch-1.0 --version<br>
gst-launch-1.0 version 1.8.3<br>
GStreamer 1.8.3<br>
<br>
My configuration:<br>
<code class="java plain">gst-launch-</code><code class="java value">1.0</code>
<code class="java plain">udpsrc uri=udp:</code><code class="java

<br>
I can't join mpedtsmux and tee.<br>
<br>
So I want to decode video, get 3 copies, each copy scale to some
resolution, encode, decode + encode audio and join to each copy of
video, output each copy in udp unicast to some port.<br>
<br>
Help, maybe someone have working solution for my task.<br>
