* commit '07a2b155949eb267cdfc7805f42c7b3375f9c7c5': Bump major versions of all libraries A few API deprecated ~2 years ago or more are also postponed here for varying reasons. FF_API_LOWRES: Since this functionality depends on AVStream->codec, i figure the two can be removed at the same time in the next bump or so. FF_API_AVCTX_TIMEBASE: Couldn't get this one to work. Not just libavcodec but apparently also libavformat and ffmpeg.c expect AVCodecContext->time_base to be set for decoding. Upon removal some tests report a different generic stream time base (like 1/25), and others lose packet duration values. I guess it's somehow tied to the AVStream->codec clusterfuck. It can be dealt with alongside FF_API_LAVF_AVCTX in the next bump. FF_API_OLD_FILTER_OPTS_ERROR: This one is meant to remain after FF_API_OLD_FILTER_OPTS is removed. Its purpose is displaying the corrected command line using the new syntax as a suggestion as part of the error message. Merged-by: James Almer <jamrial@gmail.com>
