Dears ,

Hello , I am working on a video conference project , in the client side I need to broadcast my audio and video and receive 4 audio/video from 4 another users . I have to use lead tools video conferencing SDK , in the first step I have to know what PC hardware I need to use for the best result ( CPU , RAM , etc.. ) ? ( I have to use H264 video codec and for audio codec I don't know what audio codec is better for me ) . in the second step , I should control my bandwidth usage , I have bandwidth limited to 512 Kbps .

Thanks .

Hello,

About your machine specifications, I think your machine is good enough to implement the video conferencing module.

However, to get more
information about how to use and implement the video conferencing
module in your application, please refer to the LEADTOOLS Multimedia documentation and read the following topics:
- How to do Video Conferencing using the LEADTOOLS Video Streaming Module.
- Video Conferencing FAQs.
- A Complete Example: Server and Client.

Please let me know if this helps.

Thanks,

We ship a complete Client/Server example that addresses each one of these questions in the Multimedia V15 SDK. They can be found in the below directories. I uses pre-defined compressor settings to achieve specific bit rates based on a video size of 320x240 and also shows how to change these settings programmatically.
