H264 PLUGIN in H323Plus
by ooi khai chin 19 Mar '10

Hi All, In my latest status, I able to have the conference with polycom and other softphone using H.264 plugin. But I face the problem of delaying (my movement only show on the other endpoint after around 5 seconds in local network). I think this problem occur because of fragmentation of 1 encoded picture that has size greater than 1.4KB to multiple slices, then sent it out. Currently, my default frame rate is 10fps. My question is how to solve the delaying problem because I see polycom PVX 8.0.2 and other softphone do not have any delay? Another question, If my default frame rate is 10fps, is it means that my program will call Codec Encode function 10 times in a second? As I know, inside the encode function, every time it will check for remanding frame length for last packet, if exist it repeatably packet it with size less than 1.4KB until finish, then it only start to encode a new frame. So, Let say I have one encoded picture that consist of 10 slices, is it means that I only able to sent one complete picture in 1 second (if my fps=10)? Thanks.

Re: [h323plus] [h323implementers] How does the H323Plus handles the codecs

This should be on the h323plus mailing list. You place the plugins directory next to src and header directories in the h323plus directory and then compile them seperately. This will create seperate **_p[t-w]libplugin.so files in the /release or /debug directory which you copy to your application directory or set the PTLIBPLUGINDIR env variable to point to directory you have placed your plugins. The plugins are automatically detected and loaded when you start your application.

How does it handles with de audio and video codecs? I look the source code and thought that I have to download the plugin and put then at the /include and then compile all together or I compile the source of the plugins and then put the archives *.o at the /include folder? _____ Fique protegido enquanto navega na Internet.
