Reason for revert: This breaks iOS GYP generation as described on http://www.webrtc.org/native-code/ios I'm going to drive getting the build_with_libjingle=1 setting removed from the bots to match the official instructions. See https://code.google.com/p/webrtc/issues/detail?id=4653 for more context, as this is exactly what that issue tries to solve. Original issue's description: > Add aecdump support to audioproc_f. > > Add a new interface to abstract away file operations. This CL temporarily > removes support for dumping the output of reverse streams. It will be easy to > restore in the new framework, although we may decide to only allow it with > the aecdump format. > > We also now require the user to specify the output format, rather than > defaulting to the input format. > > TEST=Bit-exact output to the previous audioproc_f version using an input wav > file, and to the legacy audioproc using an aecdump file. > > Committed: https://crrev.com/bdafe31b86e9819b0adb9041f87e6194b7422b08 > Cr-Commit-Position: refs/heads/master@{#10460} TBR=aluebs@webrtc.org,peah@webrtc.org,andrew@webrtc.org NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true Review URL: https://codereview.webrtc.org/1423693008 Cr-Commit-Position: refs/heads/master@{#10523}
