Renders the W3C IMSC test suites side by side, frame by frame.

Reference

Media3 1.11.1

Tests: w3c/imsc-tests v1.0.0-33-g14dfb67. Media3 frames are pre-rendered on the JVM (SubtitleView under Robolectric, native graphics); imscJS 2.0.0-rc.2 is rendered live. Both are sampled at the same media times (taken from imscJS). Keyboard: left and right arrows change frame.
