The following table will help you determine the most probable reason of the ingest failure and tune your ingest hardware.
Slow connection to the Cinegy video server
The ingest station is not capable of writing back the ingested streams. The output buffer size in some of the ingest encoder plug-in windows grows until it reaches a limit (normally, a few hundred frames), then the ingest stops.
Check your connection to the Cinegy servers.
Cinegy video server is not fast enough
To differentiate the situation from the previous one, test the ingest when there is no other load on the video server.
If the ingest works under lesser load on the server, consider increasing its I/O performance.
Encoder station is not powerful enough
The input buffer size in some of the ingest encoder plug-in windows grows until it reaches a limit (normally, around 100 frames), then the ingest stops.
Consider a more powerful computer.
Slow connection among the cluster machines
The output buffer of the capture plug-in overflows. The input buffer of some of the encoders falls to 0.
Problems with the capture device
The input buffer of the capture plug-in falls to 0. The plug-in reports frame drops.
Consider optimizing the PCI slot of the capture device; refer to the device documentation to learn about possible workarounds.
The buffers of the remote machines are not sufficient
From time to time you see the buffer overflow on some of the remote computers.
Consider adding some RAM to the computers. Increase the NumBuffers parameter in the IngNet.ini file.
