The serviio people get upset when someone posts their experience with serviio.
I consulted a friend who works in a computer department where there are over 2000 PC’s in use, specialised networking and competent professional support staff. They have a dedicated professional state of the art video editing centre using the latest technology. The centre is used to train students in professional video editing. I doubt that the average user would possess or have access to the technology or networking centre.
My friend did a mathematical calculation on the limitations of using a 100mbps LAN to stream video. There are also professional software tools to verify the LAN speed. The bottleneck is not in the DLNA server software regardless of whether it is freeware, open source or commercial. In fact the DLNA software inbuilt into Windows 7 exhibits identical problems as serviio streaming video through a 100mbps LAN. In view that Microsoft wrote Windows 7 to be used in a professional environment, I doubt Microsoft would display any software incompetence.
I am using the following DLNA Devices: Sony BDP S-370 bluray player Australia (EU profile); WDTV Live - WDXTV 1.03.49; 0.4.5.3; Samsung PS50C550 plasma TV.
The LAN used for video is a TP-Link TG-3269 1000mbps card connected to a Netgear GS605 5 port switch using manufactured cat 6 cables. The video LAN, media switch and DLNA devices are connected independently of the internet LAN. There is no network sharing of files or communication activity between the two LAN networks.
Seviio will stream DVD VOB files to all three DLNA devices without stutter.
Serviio will stream some bluray media through the WDTV Live without stutter. The reference bluray used was Pirates of the Caribbean 3.
Serviio will not stream bluray media through the Sony bluray player or Samsung TV without stutter. The reference bluray used was Pirates of the Caribbean 3.
Observing the Windows 7 Task Manager, the maximum CPU use when streaming bluray video is about 40% with 50% maximum memory use. The TP-Link TG-3269 1000mbps maximum use is 2%. My conclusion is that the 100mbps ports on the Sony bluray player and Samsung TV are good enough to stream DVD video but not fast enough to stream bluray video. The WDTV Live will stream DVD video. Depending on the bluray disk title, the WDTV Live may stream some of the bluray disk content without stuttering.
The bottleneck is not in my computer. The computer idles waiting for the information to be inputted from the 100mbps LAN within the consumer device. The only way to stop video stuttering is for the manufacturers to install a memory buffer in the 100mbps LAN or change to a 1000mpbs LAN. Until then be happy watching transcoded video.
