| | 74 | == Fuzzing FATE tests in libavformat, libavutil and libswscale == |
| | 75 | |
| | 76 | '''Description:''' FATE is FFmpegs self / regression test system. Fuzzing with oss-fuzz is used to find corner cases which trigger anomalies like undefined behavior. FATE tests are sub optimal to be part of fuzzing as they use hardcoded parameters as input for each test. For example libavutil/tests/des.c runs some random and fixed tests but no tests controlled by some data from a fuzzer. So even if a anomaly occurs during a random test, this would not be reproducible nor could a fuzzer direct execution towards more anomalous cases. |
| | 77 | |
| | 78 | '''Expected results:''' Connect most libavformat/tests/*.c libavutil/tests/*.c libswscale/tests/*.c tests to oss-fuzz so that the fuzzer can fully affect the data in each test. |
| | 79 | |
| | 80 | '''Prerequisites:''' Good C and Makefile coding skills, basic familiarity with Git, knowledge of oss-fuzz. |
| | 81 | |
| | 82 | '''Qualification Task:''' Connect 2 of the 60 FATE tests from libavutil / libavformat / libswscale to work under oss-fuzz, one from libavutil and one from libavformat. Passing qualification will be judged by having working code pushed into FFmpeg git and oss-fuzz git before the deadline given to us for choosing projects. |
