What information is showing in the “now playing” tile for that playback on the Plex server dashboard? Is the stream actually „local“ (not remote or indirect)? Any transcoding going on that might be too much for your server?
Good call…It said I was transcoding both video and audio. I changed the setting for that file to “allow direct play” and “allow Direct Streaming” (not sure what the difference is between them) and it is playing much better.
direct play → file is streamed as is: container, video, audio, subtitle streams are served as-is
direct stream → file is remuxed for streaming: container is adjusted on-the-fly to a compatible format while video, audio, subtitle streams are served as-is.
so… if your Plex app is on a client that cannot deal with WMV files but the embedded video/audio/subtitle streams are fully compatible, Plex might be placing the video/audio/subtitle streams into a new container. There’s no transcoding involved… just a “change of envelope”.
