| Post subject: | Multiple connections to MythTV cause pauses and freezes |
Hi, I set up a Knoppmyth server in order to stream training programs over a LAN. I installed Knoppmyth R5E50 on a system with an AthlonXP 2600+ processor, 1 GB RAM, 110 GB hard drive and a Hauppauge PVR-500 encoder card. Both the backend and frontend are on this same box, which is connected to my LAN via a 100mps full duplex connection. The client PCs run Window$. I am using the MythTV Player as a client to access video streams. This is the only player that appears to work on a Window$ workstation. I have had no luck using the Mythweb browser based interface to stream video. The Everything works great when 1 to 3 people access recordings simultaneously. But once that number goes 4 simultaneous users, the stream being fed to the MythTV Player experiences pauses, and occasionally the stream just freezes. When I test this situation, 5 people are accessing different recordings on the Knoppmyth server. I first used the default settings for the player (version 0.3.4). Then I upgraded to version 0.3.5. I changed the MythTV player settings so that it connects via a samba share rather than the myth protocol, and I disabled stream buffering as recommended in a thread on the MythTV Player forum. My question is this: Is MythTV made to support multiple simultaneous connections? If so, what is the limit, and are there settings I can change on the backend that would help create more stable viewing performance when several people are simultaneously accessing video? Any assistance with this issue would be greatly appreciated. Thanks, Ken |

What sort of network backbone do you have? You may just be running out of network bandwidth. At the bitrate I use for my PVR350, it takes sustained throughput of about 4-5Mbps to stream a program. An "11Mbps" wireless link can just barely keep up. It only takes a few streams like that to max out a 100M Ethernet link -- particularly if it's half-duplex or is running through a cheap switch. |
