Otherwise, there is no guarantee that the various av_log-messages are not interrupted by another log statement. The latter may originate from anywhere else, even the HEVC decoder itself, as happens when one uses frame-threading to decode the BUMPING_A_ericsson_1.bit sample from the FATE-suite. Furthermore, the earlier approach suffered from the fact that various parts of the logmsg were output with different loglevels and that checking stopped after having encountered the first plane with MD5 mismatch, although it is probably interesting to know whether other planes are incorrect, too.
