Problem Description:
Live TV stream video freezes - Audio Continues
Hardware:
Frontends are AppleTV1's (3) that are running Crystalbuntu 2 with crystalHD cards. SSD harddrives. XBMC 13.2
TV signal source is HDHomerun Plus running beta firmware 2014623beta1. This also occurred on current firmware 20140606. Signal strength is >85. symbol quality is rock steady 100. Data signal quality is >85. Transcode profile is heavy, but problem remains when using mobile profile.
Backend is Win7 PC with a quad core processor. CPU load never exceeds 10% and typically is <5% when problem occurs. 8GB ram with ~30% free. Network LAN connection load is <5%.
Network is a wired gigabit connection to AppleTV's and Backend. Managed gigabit switch and all connections are direct to switch (no intermediate switches) and QOS tagging on AppleTV's and Backend server is set to highest priority. Problem remains when QOS is set to disabled. Network line analysis show no alignment or collision errors.
Further info:
Problem is intermittent. Sometimes the stream will play for an hour or so uninterrupted. Most times the problem will occur within 10 minutes of starting a stream. It occurs most frequently on one particular station (7.1) which is the highest bandwidth station, but also occurs on other stations. When playing this station directly on WMC on the backend it does not occur. Also playing this station on the ATV's through the UPnP connection HDHomerun it does not occur. Playing the HDHomerun on mobile devices using InstaTV has no problems. Thus my belief that the problem is centered around ServerWMC.
If I wait long enough (>5 minutes) the video stream will restart by itself, but will then freeze again. Most times when the freeze occurs, a "buffering" window will briefly pop up, but occasionally it will just freeze without notice.
Log file for ServerWMC can be found here: http://pastebin.com/RCSqVJiy
What I have done so far:
Bumped the Timeout_WaitForTS_MS to 20000 from the default 10000. No help from this. Also tried 30000 with no results.
ServerWMC version is 1.0.0.36 Build 1154. Frontend pvr versions are 0.2.99. Crystalbuntu version 0.3.100
AppleTV's run 1080p movies (streaming and local network NAS) files flawlessly, so I don't think the issue is there. The CPU load on the ATV's is around 55-60% when streaming Live TV. Free memory is ~125MB at idle. ~30MB when streaming.
Please help. I have ditched cable and am trying to convince my wife that this will work, but the freezing issues are a pain. Constantly restarting the stream is not a solution to her.
Thanks for the work you have done on this product. It really is a great product with just a few small problems.
