This reverts commit 63d03f586bb668f72113b61030ec0930aa192010. Reason for revert: Breaks downstream project (not backwards compatible API change) Original change's description: > Unify access to SDP codec parameters > > which come from the a=fmtp:<pt> lines in the SDP and were used as either > std::map<std::string, std:string> > with three aliases, > cricket::CodecParameterMap > SdpAudioFormat::Parameters > SdpVideoFormat::Parameters > > Use webrtc::CodecParameterMap in all places. > > BUG=None > > Change-Id: If47692bde7347834c349c6539b43309d8770e67b > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/330420 > Reviewed-by: Florent Castelli <orphis@webrtc.org> > Reviewed-by: Harald Alvestrand <hta@webrtc.org> > Commit-Queue: Philipp Hancke <phancke@microsoft.com> > Cr-Commit-Position: refs/heads/main@{#41375} Bug: None Change-Id: I841735d98533d3b66850b9cfcf7ee0a99ddde078 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/331400 Commit-Queue: Mirko Bonadei <mbonadei@webrtc.org> Auto-Submit: Mirko Bonadei <mbonadei@webrtc.org> Owners-Override: Mirko Bonadei <mbonadei@webrtc.org> Bot-Commit: rubber-stamper@appspot.gserviceaccount.com <rubber-stamper@appspot.gserviceaccount.com> Cr-Commit-Position: refs/heads/main@{#41377}
