No source file or test is named. Reproduce playback on Android 4.2 with ijkplayer 0.8.4 using the provided initIjkPlayer settings, especially mediacodec hardware decoding, then trace the relevant playback behavior. Done means identifying the cause of the flickering and verifying stable video playback.
