 This folder includes test fixtures associated with testing video encoder and decoder components such as simple encoding of a raw clip or decoding of an elementary stream, end of stream test, timestamp deviations test, flush test and so on. These tests are aimed towards testing the plugin that connects the component to the omx core.
