Codec Tables
The goal is to Direct Play all media. This means the container, video, audio and subtitles are all compatible with the client. If the media is incompatible for any reason, Jellyfin will use FFmpeg to convert the media to a format that the client can process. Direct Stream will occur if the audio, container or subtitles happen to not be supported. If the video codec is unsupported, this will result in video transcoding. Subtitles can be tricky because they can cause Direct Stream (subtitles are remuxed) or video transcoding (burning in subtitles) to occur. This is the most intensive CPU component of transcoding. Decoding is less intensive than encoding.
