This makes the code 7 times faster with the testcase from libfuzzer
and should reduce the amount of timeouts we hit in automated fuzzing.
(for example 438/fuzz-2-ffmpeg_VIDEO_AV_CODEC_ID_RV40_fuzzer)

The code is also faster with more realistic input though the difference
is small here as that is far from the worst cases the fuzzers pick out
