Server Version#: 9.2.1.32664 Player Version#: 4.76.1 Trying to run a transcode on a DVR recording from an HDHomeRun device. The transcode is able to start/create an output file. The transcoded file has a black video when played from any plex client.

> [@DV2K](#): > > from an HDHomeRun device Which model? I don’t see anything obviously wrong in file info. I’m assuming you mean you were trying to make an Optimized for Mobile version. Does it do the same if you choose Optimized for TV? ---

> Which model? > HDHomeRun EXTEND (HDTC-2US) and HDHomeRun PRIME (HDHR3-CC) > Does it do the same if you choose Optimized for TV? > Yup, video issue happens with any of the default options and played with the custom settings as well ,same BLACK video after running the Optimize command. The source video will record/play on any plex client (shieldTV/phone/pc/web) . On a test client using LTE the source file will transcode (on the fly) if I set the plex client Settings → Quality → Remote steaming quality 2 mbps. The blank/black video issue seems to be linked to the Optimize feature. 2 speed up testing, ran the following command to create a 30 sec test file, then hit ‘Scan Library Files’ to update plex with the new test file. ffmpeg -i “The.Late.Show.With.Stephen.Colbert.(2015)-S07E136.ts” -ss 00:00:00 -t 00:00:30 -c:v copy -c:a copy The.Late.Show.With.Stephen.Colbert.(2015)-S07E130.ts happy to share the 30 sec source file if needed, its around 36 mb in size. PS Had to explain what a “BigWheel” was to my kid, then I showed him a Huffy Green Machine was, his mind was blown ! ---
