Besides, the article focuses on the details that may be easily missed when decoding video, and finally, it briefly explains how to package a VideoDecoder with basic video decoding functions.

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.This article firstly introduces the main process and basic principle of decoding video with FFmpeg as the topic secondly, it also describes the simple applications related to FFmpeg video decoding, including how to play video in a certain timeline order based on the original FFmpeg video decoding, and how to add the logic of seek when playing video. 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. The current state of hardware acceleration support in FFmpeg can be checked on the rpi-ffmpeg repository. 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.
