Research direction

The crash is in the video info callback StreamBase$getVideoData$1.onVideoInfo, reached from VideoEncoder.requestKeyframe (VideoEncoder.java:263) during checkBuffer. Start by reading how StreamBase.getVideoData sets up that callback and why a field it uses can be null when the encoder emits an output buffer. The issue has no reproduction steps and no test, so 'done' needs a device or emulator run that reproduces the NPE, then a fix that stops it. Expect to ask the maintainer for steps first.
