Choppy / unsmooth playback when casting YouTube

Problem

If you cast from YouTube app on your phone, you will notice the playback performance is quite bad. The video is not smooth, and there may be an error message displayed on the screen. This is a known issue.

Temporary Solution

Use SmartYouTube instead:

• First, turn off Google Cast by going to Projector Settings > Mirroring > iOS > Google Cast and pressing OK on it to uncheck the option.
• Next, open SmartYouTube, on the left side go to Settings at the bottom and choose either Link with WiFi or Link with TV code (recommended). Then follow the on-screen instructions.

Once you’ve linked your phone to the projector using this method, wireless YouTube casting will have perfect playback performance.

You can also press [OK], then go to QUALITY - VIDEO and choose a better quality. We suggest using 1920 x 1080 at up to 60 fps, and the vp9 codec.

Background

Due to a bug, the built-in YouTube cast implementation is not using hardware decoding on the projector. The video playback uses software decoding, which has bad performance. We plan to fix this in an update. In the meantime, using SmartYouTube’s casting feature will give you perfect playback, since it does use hardware decoding.
