![]() No stuttering and trustd usage should not be using 50% of CPU.Here are two YouTube videos of what I have described: Nor does the error occur on other devices, only on Mac. This error does not occur when playing the video directly from the Mac, only through Plex media player. When playing another video this will not occur on most TV and Films.īoth are using Direct play for audio and video and are not being transcoded on the server. This high trustd usage will continue until I stop playing one of the affected media. In this image I am playing an episode from the Big Bang Theory:Īs you can see from the media info the episode from the Big Bang Theory is using a lower bitrate and lower quality than 1917, yet The Big Bang Theory stutters and 1917 does not. Up to approximately 50% CPU usage (Note that this only occurs on episodes that are stuttering, other media work fine). This is accompanied with high trustd (I think one of Apples bundled processes) usage in activity monitor. Stuttering on the video making it unwatchable.Although the exact show is probably not relevant, there's a mix of file types that I am experiencing this on.) In such a situation, make sure the whole file names were being recognized by Plex. If random named MKV video not showing in Plex, you may find it in 'rencentlyadded' column. Play a TV or film (Media that I know stutter on Plex Media Play for Mac are: The Big Bang Theory, 300, X-Men. Poor named MKV movies might have been matched as a different movie.Ensure that you are using Plex Media player.Use a Macbook Air (Tested with Early 2014 13'3 inch version and later 2020 with Apple M1).Platform: macOS version 11.0.1 Steps to reproduce If your Jellyfin server does not support hardware acceleration, but you have another machine that does, you can leverage rffmpeg to delegate the transcoding to another machine.PMP Version: Plex Mac version: 1.24.-714cba36 The hardware acceleration is available immediately for media playback. Supported codecs need to be indicated by checking the boxes in Enable hardware decoding for and Hardware encoding options. Select a valid hardware acceleration method from the drop-down menu and a device if applicable. Hardware acceleration options can be found in the Admin Dashboard under the Transcoding section of the Playback tab. I know Plex transcodes on their server so considering the Pi (even though. The current state of hardware acceleration support in FFmpeg can be checked on the rpi-ffmpeg repository. Im a newbie to Pis and a relative newbie to audio and visual technicals so. Jellyfin will fallback to software de/encoding for those usecases. This decision was made because Raspberry Pi is currently migrating to a V4L2 based hardware acceleration, which is already available in Jellyfin but does not support all features other hardware acceleration methods provide due to lacking support in FFmpeg. Video Scaling & Format conversion (optional)Īs of Jellyfin 10.8 hardware acceleration on Raspberry Pi via OpenMAX OMX was dropped and is no longer available. The transcoding pipeline usually has multiple stages, which can be simplified to: Raspberry Pi Video4Linux2 (V4L2, Linux only) Intel/AMD Video Acceleration API (VA-API, Linux only) The supported and validated video hardware acceleration (HWA) methods are: It enables the Jellyfin server to access the fixed-function video codecs, video processors and GPGPU computing interfaces provided by vendor of the installed GPU and the operating system. The Jellyfin server uses a modified version of FFmpeg as its transcoder, namely jellyfin-ffmpeg. The Jellyfin server can offload on the fly video transcoding by utilizing an integrated or discrete graphics card ( GPU) suitable to accelerate this workloads very efficiently without straining your CPU.
