Is Ultra-Videoconferencing RTP-compliant?
No. Ultra-Videoconferencing is not RTP-compliant, nor do we have any immediate plans to make it so. The software uses its own transport mechanism that was developed specifically for our needs, some of which are incompatible with RTP. • What video modes are supported by Ultra-Videoconferencing? Ultra-Videoconferencing supports video input from either frame grabbers using v4l or v4l2 interfaces (e.g. Bt878 chipset), digital video (DV) cameras, DCAM (raw, uncompressed video) 1394 devices, and standard or high-definition Serial Digital Interface (SDI). • Why do I see frequent reports of bad frames or missing fragments when receiving video, even though I believe I have plenty of network capacity? The default IP buffers provided by the system are generally far too small to support the demands of video reception, even for compressed video such as DV. In order to correct this, you should (as root) increase the buffer temporarily with sysctl -w net.core.rmem_max=500000 or permanently, by adding
