Reason for revert: Broke all Chromium libFuzzer builds https://bugs.chromium.org/p/chromium/issues/detail?id=645069 Original issue's description: > Setting up an RTP input fuzzer for NetEq > > This CL introduces a new fuzzer target neteq_rtp_fuzzer that > manipulates the RTP header fields before inserting the packets into > NetEq. A few helper classes are also introduced. > > BUG=webrtc:5447 > NOTRY=True > > Committed: https://crrev.com/2d273f1e97cd5030ed1686f27ce1118291b66395 > Cr-Commit-Position: refs/heads/master@{#14103} TBR=ivoc@webrtc.org,kjellander@webrtc.org # Skipping CQ checks because original CL landed less than 1 days ago.
