* avformat/avformat: Add FFInputFormat, hide internals of AVInputFormatAndreas Rheinhardt2024-03-07
| | | | | | | | | | | | | | | | | | | | | 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.)

* avformat: Avoid allocation for AVFormatInternalAndreas Rheinhardt2021-09-17
| | | | | | | | | | | | | Do this by allocating AVFormatContext together with the data that is currently in AVFormatInternal; or rather: Put AVFormatContext at the beginning of a new structure called FFFormatContext (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVFormatInternal altogether. The biggest simplifications occured in avformat_alloc_context(), where one can now simply call avformat_free_context() in case of errors.

* avformat/adp, svs: Remove redundant av_shrink_packet()Andreas Rheinhardt2021-03-12
| | | | | | | | | av_get_packet() already makes sure that the packet size is accurate and that the packet data is zero-padded even when one could not read as much as desired. Reviewed-by: James Almer <jamrial@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
