How to cast and download TRT Çocuk videos
Tested October 27, 2026 with Castmate for Chrome.
- Open the TRT Çocuk video in Chrome and start playing it.
- Click the Castmate icon in the toolbar. The video shows up with its title, length and quality.
- Press Cast and pick your TV. The TV plays the stream itself, in full quality, so you can close the laptop.
- Or press Download, then Save to computer, to keep it as one MP4 file. (Saving comes with the next Castmate update, 1.0.5.)
What we found
- Casting works directly. The TV fetches the stream itself; nothing else needs to run on your computer.
- Saving works: one MP4 file with picture and sound.
