* avformat/avformat: Add FFInputFormat, hide internals of AVInputFormatAndreas Rheinhardt2024-03-071-18/+19
| | | | | | | | | | | | | | | | | | | | | 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.)

* Revert "all: Don't set AVClass.item_name to its default value"Anton Khirnov2024-01-201-0/+1
| | | | | | | Some callers assume that item_name is always set, so this may be considered an API break. This reverts commit 0c6203c97a99f69dbaa6e4011d48c331e1111f5e.

* avformat: Forward errors where possibleAndreas Rheinhardt2019-12-121-11/+13
| | | | | | | | | | It is not uncommon to find code where the caller thinks to know better what the return value should be than the callee. E.g. something like "if (av_new_packet(pkt, size) < 0) return AVERROR(ENOMEM);". This commit changes several instances of this to instead forward the actual error.
