This reverts commit2ea9af2275. Reason for revert: The problem will be fixed by https://chromium-review.googlesource.com/c/chromium/src/+/1261122. Original change's description: > Revert "Export symbols needed by the Chromium component build (part 1)." > > This reverts commit9e24dcff16. > > Reason for revert: Breaks chromium.webrtc.fyi bots. > > Original change's description: > > Export symbols needed by the Chromium component build (part 1). > > > > This CL uses RTC_EXPORT (defined in rtc_base/system/rtc_export.h) > > to mark WebRTC symbols as visible from a shared library, this doesn't > > mean these symbols are part of the public API (please continue to refer > > to [1] for info about what is considered public WebRTC API). > > > > [1] - https://webrtc.googlesource.com/src/+/HEAD/native-api.md > > > > Bug: webrtc:9419 > > Change-Id: I802abd32874d42d3aa5ecd3c8022e7cf5e043d99 > > Reviewed-on: https://webrtc-review.googlesource.com/c/103505 > > Commit-Queue: Mirko Bonadei <mbonadei@webrtc.org> > > Reviewed-by: Niels Moller <nisse@webrtc.org> > > Reviewed-by: Karl Wiberg <kwiberg@webrtc.org> > > Cr-Commit-Position: refs/heads/master@{#24969} > > TBR=mbonadei@webrtc.org,kwiberg@webrtc.org,nisse@webrtc.org > > Change-Id: I01f6e18f0d2c0f0309cdaa6c943c3927e1f1f49f > No-Presubmit: true > No-Tree-Checks: true > No-Try: true > Bug: webrtc:9419 > Reviewed-on: https://webrtc-review.googlesource.com/c/103720 > Reviewed-by: Mirko Bonadei <mbonadei@webrtc.org> > Commit-Queue: Mirko Bonadei <mbonadei@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#24974} TBR=mbonadei@webrtc.org,kwiberg@webrtc.org,nisse@webrtc.org Change-Id: I83bbc7f550fc23e823c4d055e0a6f60c828960dd No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: webrtc:9419 Reviewed-on: https://webrtc-review.googlesource.com/c/103740 Reviewed-by: Mirko Bonadei <mbonadei@webrtc.org> Commit-Queue: Mirko Bonadei <mbonadei@webrtc.org> Cr-Commit-Position: refs/heads/master@{#24980}
