We’re having a problem with webcam publishing taking very long to clear the client buffer. Our flash player is using a modified form of the web cam recorder example given with the Wowza installation. The quality is still set to camera.SetQuality(0, 88). We’ve played with these numbers (plus the buffering setting) and can occasionally hit it where our testers are all pleased with the results, but eventually something changes and the video becomes pixelated or the video becomes jerky. So we’re back to (0, 88) and things are fine. This afternoon though, I recorded a 40 second video that began filling the buffer immediately, so that at 40 seconds, there were 20 seconds of buffer filled. It then took almost 60 seconds to unload the buffer before receiving the NetStream.Unpublish.Success status and unpublishing.
My frustration is that I can’t seem to tune these settings so that everyone is happy. Our client bandwidth seems to be fairly decent (outbound speeds range from 350 Kb/s to 500 Kb/s). Mine is at 415 Kb/s and I just don’t get why the buffer fills and takes so long to unload.
When I analyze the stats on the published file, the datarate seems to be 410 Kb/s or so. I’ve read the manuals and am struggling to keep all our testers happy with the results. Is such a delay in unloading the buffer normal? Maybe I should just accept it and move on…
Any thoughts?
Thanks,
Dono.
