TCPCam is a video and audio point to point conference program for Linux that is very easy to use and modify. The connection uses a single TCP port that needs to be open on only one of the two ends.
TCPCam is possible to change the video compression and resolution at run-time to match the available bandwidth.
It uses the Speex encoder for audio compression (in both narrowband and wideband), JPEG compression for video, and works with most video4linux devices and audio boards supporting the OSS API.
Here are some key features of "TCPCam":
- It works using a single TCP port (port 7766). In order for TCPCam to work between two users, one of the users can be completly firewalled, while the other one must have port TCP 7766 open to the outside.
- Audio frames are encoded using the Speex encoder/algorithm.
- Video frames are encoded using JPEG at high compression level.
- The user can switch between ten different video quality levels at runtime using keys from 1 to 0.
- Support for multiple video resolution (up to 640x480), the user can switch at runtime using the right keys (see usage)
- Full screen mode (just press 'f' to toggle).
- Capture screenshots in JPEG format (just press 'enter').
- Audio works in narrowband (8Khz) and wideband (16Khz).
- The protocol is very simple to implement in most operating systems and programming languages. It is based on frames with a simple header containing audio or video and transimtted over a TCP channel.
