What File Formats Does Chromecast Support?

Trying to cast a video and not sure if the file format will work? Here’s what Chromecast and Google Cast devices support today.

Supported Video and Audio Formats

• Video codecs: H.264, VP8, VP9, and HEVC (H.265) on newer Chromecast and Google TV devices
• Audio codecs: AAC, MP3, Opus, and FLAC
• Containers: MP4, WebM, MPEG-DASH, and HLS
• Subtitles: WebVTT and TTML

What If Your File Won’t Cast

If a video won’t play, the easiest fix is usually casting through an app that handles conversion for you, like YouTube, Google Photos, or a streaming app, rather than casting a raw video file directly.

Quick Tips

• Newer Chromecast with Google TV devices support more formats, including AV1, than older Chromecast dongles.
• If you’re casting from a phone or computer using a casting app, that app’s own format support matters too, not just the Chromecast’s.

Sticking to common formats like MP4 and H.264 gives you the best chance of trouble-free casting on any Chromecast device.
