Test Results

Sony Xperia z3c w/ b2g

Playback is with Gaia's video player. Currently a bug causes WebM to playback in the wrong aspect ratio. The Snapdragon 801 in the z3c has hardware H.264 playback, but VP9 playback is provided via software.

Nexus 7 2013

The Nexus 7 has a hardware H264 decoder, but only software VP9. MX Player is used for playback.

Lenovo Thinkpad W540

TBD, the power connector I ordered is missing the middle pin so the laptop won't charge.
