Reason for revert: Necessary calls were "protected" by RTC_DCHECKs, that were optimized away in some release builds. Replacing the RTC_DCHECKs with EXPECTs. Original issue's description: > Revert of Add optional visualization file writers to VideoProcessor tests. (patchset #4 id:220001 of https://codereview.webrtc.org/2700493006/ ) > > Reason for revert: > Breaks downstream project. > > Original issue's description: > > Add optional visualization file writers to VideoProcessor tests. > > > > The purpose of this visualization CL is to add the ability to record > > video at the source, after encode, and after decode, in the VideoProcessor > > tests. These output files can then be replayed and used as a subjective > > complement to the objective metric plots given by the existing Python > > plotting script. > > > > BUG=webrtc:6634 > > > > Review-Url: https://codereview.webrtc.org/2700493006 > > Cr-Commit-Position: refs/heads/master@{#16738} > > Committed:872104ac41> > TBR=asapersson@webrtc.org,sprang@webrtc.org,kjellander@webrtc.org > # Skipping CQ checks because original CL landed less than 1 days ago. > NOPRESUBMIT=true > NOTREECHECKS=true > NOTRY=true > BUG=webrtc:6634 > > Review-Url: https://codereview.webrtc.org/2708103002 > Cr-Commit-Position: refs/heads/master@{#16745} > Committed:2a8135a174TBR=asapersson@webrtc.org,sprang@webrtc.org,kjellander@webrtc.org # Skipping CQ checks because original CL landed less than 1 days ago.
