This reverts commit 7dd83e2bf73a7f1746c5ee976939bf52e19fa8be. Reason for revert: This wasn't the cause of the break. Original change's description: > Revert "Refactor FrameDecryptorInterface::Decrypt to use new API." > > This reverts commit 642aa81f7d5cc55d5b99e2abc51327eed9d40195. > > Reason for revert: Speculative revert. The chromium roll is failing: > https://ci.chromium.org/p/chromium/builders/try/linux-rel/64388 > But I can't figure out exactly what is failing, this looks suspecious. > > Original change's description: > > Refactor FrameDecryptorInterface::Decrypt to use new API. > > > > This change refactors the FrameDecryptorInterface to use the new API. The new > > API surface simply moves bytes_written to the return type and implements a > > simple Status type. > > > > Bug: webrtc:10512 > > Change-Id: I622c5d344d58e618853c94c2f691cf7c8fb73a36 > > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/131460 > > Reviewed-by: Steve Anton <steveanton@webrtc.org> > > Reviewed-by: Fredrik Solenberg <solenberg@webrtc.org> > > Reviewed-by: Rasmus Brandt <brandtr@webrtc.org> > > Reviewed-by: Stefan Holmer <stefan@webrtc.org> > > Commit-Queue: Benjamin Wright <benwright@webrtc.org> > > Cr-Commit-Position: refs/heads/master@{#27497} > > TBR=brandtr@webrtc.org,steveanton@webrtc.org,solenberg@webrtc.org,ossu@webrtc.org,stefan@webrtc.org,benwright@webrtc.org > > Change-Id: Ia9ec70263762c34671af13f0d519e636eb8473cd > No-Presubmit: true > No-Tree-Checks: true > No-Try: true > Bug: webrtc:10512 > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/132013 > Reviewed-by: Henrik Boström <hbos@webrtc.org> > Commit-Queue: Henrik Boström <hbos@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#27510} TBR=brandtr@webrtc.org,steveanton@webrtc.org,solenberg@webrtc.org,hbos@webrtc.org,ossu@webrtc.org,stefan@webrtc.org,benwright@webrtc.org Change-Id: I8e4b7965cf1d1a1554c3b46e6245f5ad0d2dcbb4 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: webrtc:10512 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/131982 Reviewed-by: Benjamin Wright <benwright@webrtc.org> Commit-Queue: Benjamin Wright <benwright@webrtc.org> Cr-Commit-Position: refs/heads/master@{#27529}
