Karsten Suehring authoredAMVR (formely IMV) now has only one mode, which used to be mode #2 - remove SPS imv_mode parameter - remove encoder configuration for mode #1 (mode #2 replaces mode #1) - adapt config files to refer tp mode #1 - rename SPS syntax elements and access functions to AMVR Note: IMV to AMVR renaming in other parts of the software should be done by proponents.
