* avutil/common: Don't auto-include mem.hAndreas Rheinhardt2024-03-311-0/+1
| | | | | | | | | | | There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/avformat: Add FFInputFormat, hide internals of AVInputFormatAndreas Rheinhardt2024-03-071-3/+3
| | | | | | | | | | | | | | | | | | | | | This commit does for AVInputFormat what commit 59c9dc82f450638a3068deeb1db5c56f6d155752 did for AVOutputFormat: It adds a new type FFInputFormat, moves all the internals of AVInputFormat to it and adds a now reduced AVInputFormat as first member. This does not affect/improve extensibility of both public or private fields for demuxers (it is still a mess due to lavd). This is possible since 50f34172e0cca2cabc5836308ec66dbf93f5f2a3 (which removed the last usage of an internal field of AVInputFormat in fftools). (Hint: tools/probetest.c accesses the internals of FFInputFormat as well, but given that it is a testing tool this is not considered a problem.)
