Hello,<br>
<br>
I noticed that encoder_set_options of h263-ffmpeg plugin only works
while codec initialising. So if you are interested to change bandwidth
or quality setting during a videocall you must modify the plugin.<br>
<br>
<br>
in encoder_set_options: add<br>
<b><br>
context->Lock();<br>
context->CloseCodec();<br>
<br>
/* here options changing ... */<br>
<br>
context->OpenCodec();<br>
context->Unlock();</b><br>
<br>
Then add two function Lock and UnLock to H263_Base_EncoderContext with
a mutex to ensure no encoding frames while openning or closing a codec!<br>
<br>
<b><i> CriticalSection _mutex;<br>
void Lock() { _mutex.Wait(); }<br>
void Unlock() { _mutex.Signal(); }</i><br>
</b><br>
Add a mutex signal to the beginning of <br>
<i><br>
<b>H263EncoderContext::~H263EncoderContext()<br>
{<br>
WaitAndSignal m(_mutex);</b></i><br>
<br>
/* function code...*/<br>
<br>
and<br>
<b><br>
<i>int H263EncoderContext::EncodeFrames(const BYTE * src, unsigned
& srcLen, BYTE * dst, unsigned & dstLen, unsigned int &
flags)<br>
{<br>
WaitAndSignal m(_mutex);</i></b><br>
<br>
/* function code...*/<br>
<br>
<br>
So the parameters of ffmepg h263 become usable at least! <br>
<br>
Anyone tried with h263-1998 ? I'm still not able to make it working for
h323 for same reasons I mentioned in my first post. Could be
interesting to share some ideas!<br>
<br>
<br>
Greetings,<br>
Carlo<br>

Hello Everyone,<br>
<br>
I've been experimenting Opal plugins on h323plus stack. I would like to share
you my experience as it seems to me that most opal plugins doesn't work for
h323plus.<br>
<br>
I compiled plugins along with correct ffmpeg and x264 revisions, on both
windows and linux platforms. Here is my test results:<br>
<br>
H.261vic
OK<br>
H.263_ffmpeg OK<br>
<br>
H.263_1998 * Crashes before
packetising process, it works after I delay the packetiser function.<br>
* Video pixels are melting strikes, even while disabling all h263 annexes.<br>
<br>
<br>
MPEG4 * AVCodec crashes
on encoder function<br>
<br>
H.264 * It doesn't
compile at all after activating H323_H264_TEST<br>
* Complains about some missing constants, which I added<br>
* Compilation errors in structure definitions (h323 capabilities)<br>
<br>
Theora
Not tested<br>
<br>
<br>
I'm unsure about the development priority and/or status of video plugins, as no
document states that. Anyone tried to experiment video codecs using h323plus?!
do you have same results as me?! <br>
<br>
Thanks, I appreciate.<br>
