Hi,
here at microskills we've built a simple videochat web application with
openlaszlo and it works fine. Now we have the need to record the
conversations so thought I'd simply use the mediastream's and/or
videoview's record() method - instead of broadcast()/play().
For the streams of the "local" camera and microphone this works,
although the sound is a very strange, but I can't record the "remote"
streams. The .flv files are created but have size 0.
Can anyone help me out? Thank you for your time.
Take care.
Here is the source code:
...
<!-- local streams, this works fine -->
<mediastream id="local_rec" url="${parent.user_local_rec.text}" type="rtmp">
<camera id="cam_rec" show="false"/>
</mediastream>
<mediastream id="local_mic_rec"
url="${parent.user_local_mic_rec.text}" type="rtmp">
<microphone id="micro_rec" capturing="false"/>
</mediastream>
<button text="broadcast">
<attribute name="text" value="${micro.capturing == false ? 'Broadcast'
: 'Stop'}"/>
<method event="onclick"><![CDATA[
if (micro.capturing == false) {
cam.setAttribute("show", true);
micro.setAttribute("capturing",true);
micro_rec.setAttribute("capturing",true);
local_mic_rec.record();
local_rec.record();
local_mic.broadcast();
local.stream.broadcast();
} else {
local_mic.stop();
local.stream.stop();
local_mic_rec.stop();
local_rec.stop();
micro_rec.setAttribute("capturing",false);
micro.setAttribute("capturing",false);
cam.setAttribute("show", false);
}
]]>
</method>
</button>
...
<!-- remote streams, this doesn't record -->
<!--Mostra a stream de video do outro participante no chat-->
<videoview name="remoto" bgcolor="black"
url="${parent.user_remoto.text}" type="rtmp" width="200" height="200"/>
<!--Reproduz a stream de audio do outro participante do chat-->
<mediastream name="remoto_mic"
url="${parent.user_remoto_mic.text}" type="rtmp"/>
<!--Indicar o nome do outro participante no chat-->
<edittext name="user_remoto">test</edittext>
<edittext name="user_remoto_mic">test_mic</edittext>
<edittext name="user_remoto_rec">test_rec</edittext>
<edittext name="user_remoto_mic_rec">test_mic_rec</edittext>
<view>
<simplelayout axis="x" spacing="10" />
<button text="Receive">
<method event="onclick"><![CDATA[
// parent.parent.remoto_mic.play();
// parent.parent.remoto.stream.play();
parent.parent.remoto_mic.record();
parent.parent.remoto.stream.record();
]]>
</method>
</button>
<button text="Stop">
<method event="onclick"><![CDATA[
parent.parent.remoto_mic.stop();
parent.parent.remoto.stream.stop();
]]>
</method>
</button>
</view>
</view>
