Our company recently began using Wowza to stream out collections of video files as looped "virtual channels". We schedule the files as a playlist in a .smil file and then broadcast them via UDP multicast to the local network. These are then played by Amino STBs. The videos are all H.264/AAC.
The files play and loop correctly, but we get occasional video stutters, where the video will lock up for a few seconds while the audio continues smoothly. We are currently testing with 5 standard-definition channels.
The load seems very low on the server, so I'm looking for ideas on troubleshooting the performance. Any help would be greatly appreciated.
