/**
* <p>QuirkSummary
* Bug Id: b/306557279
* Description: Quirk denotes that the codec gets stuck when the {@link MediaCodec#flush()}
* method is called. The issue only occurs when the mime type is "video/mp4v-es";
* "video/avc" works fine. This could be a timing issue in the codec
* implementation that arises after continuously calling the
* {@link MediaCodec#signalEndOfInputStream()} and {@link MediaCodec#flush()}
* methods. One workaround is to call the {@link MediaCodec#flush()} method
* until the end-of-stream output buffer has been received. This can
* defer the timing to call {@link MediaCodec#flush()} and can avoid
* the issue by experimental results.
* Device(s): Nokia 1
