GoChromecast

GoChromecast is a simple tool to stream your videos to your Android TV or google Chromecast device.

Requirements

Since chromecast supports only certain formats I have prepared a small open source video spring_original you can cast found in data_dir

Casting to tv

To use it run go run ./cmd/mdns/mdns

It will try to discover devices for 5s and output results.

In last log lines it will output device names that it finds on network.

2025/02/23 20:34:00 got devices on your network names:'[]string{"myAndroidName", "Iskon\\"}' url:'192.168.0.149:8009'
2025/02/23 20:34:00 got devices on your network names:'[]string{"myAndroidName2\\ tv", "TPM192E"}' url:'192.168.0.141:8009'

After that pass that device name to cast command

    go run ./cmd/cast/cast.go -device myAndroidName

You should now see your movie spring_original beeing played on your tv together with subtitles.

Future development

I might improve the chromecast thing adding features to it, however i don't plan on adding ffmpeg support at this time.
