Plex version: 1.25.2.5319
This occurs when I am streaming on my Roku TV, but only once it gets close to the end of the file (timing doesn’t seem consistent, but anytime within the last 5 minutes).
After it crashes playback stops, I can restart playing but it will again crash when it gets close to the end. It does not crash at the same place every time.
I have to explicitly change the stream settings to be Direct Play → Force in Roku in order to watch a video without it crashing.
When it segfaults is when it is transcoding:
Video
1080p (H.264) → 1080P (H264)—Transcode
Audio
English (AAC Stereo) → EAC3—Transcode
