Android video thumbnail: h264 video thumbnail not working on emulator

Project Member Reported by xingliu@chromium.org, Oct 3 
Chrome Version: 71.0.3569
OS: Android

On a Android emulator, go/crow

(1) Enable downloadhomev2 feature.
(2) Download h264 video.
(3) The video thumbnail backend yields a bitmap with all 0 pixel data.

This works on real devices.

On emulator, egl surface throws some error. The egl surface is needed to render the video frame texture into pixel data. The texuture might be in a good state since the video playback works.

This is mostly depend on if the graphic driver works for the egl surface we trying to create.

Seems the emulator using google's h264 decoder also throws some error: UnsupportedSetting(0x80001019)

Lower priority of this, but we still need to investigate if h264 hardware thumbnail code path works on all devices.
