Build using Docker

Since the repo provides a Dockerfile, you can build a Go2TV Docker image and run it with just Docker installed (no build requirements and deps above needed). Also, no Git repo cloning is needed (Docker will do it behind the scenes). Just issue:

$ docker build --force-rm [--pull] -t go2tv github.com/alexballas/go2tv#main

Notice the branch name after the #, as the above will build main. You can also build devel if you want to build the latest code. Usage under Docker is outside this document's scope, check Docker docs for more information, specially volume mounts and networking. x11docker might come handy to run GUI mode, although it's not tested, since main Docker usage is CLI.

Download the app here https://github.com/alexballas/Go2TV/releases/latest. A single executable. No installation or external dependencies.

Transcoding (ffmpeg required)

Go2TV supports live video transcoding, if ffmpeg is installed. When transcoding, SEEK operations are not available. Transcoding offers the maximum compatibility with the various file formats and devices. Only works with video files.

MKV/MP4 Subtitle Selection Support (ffmpeg required)

Go2TV also supports selecting subtitles for video files that have embedded subtitle tracks. This functionality requires ffmpeg to be installed. You can choose the desired subtitle track when casting your media files, enhancing your viewing experience on UPnP/DLNA Media Renderers and Smart TVs.
