* avformat/ape: Use 64bit for final frame sizeMichael Niedermayer2024-06-01
| | | | | | | Fixes: CID1505963 Unintentional integer overflow Sponsored-by: Sovereign Tech Fund Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avutil/common: Don't auto-include mem.hAndreas Rheinhardt2024-03-31
| | | | | | | | | | | 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/internal: Move FF_FMT_INIT_CLEANUP to demux.hAndreas Rheinhardt2024-03-26
| | | | | | | | | and rename it to FF_INFMT_INIT_CLEANUP. This flag is demuxer-only, so this is the more appropriate place for it. This does not preclude adding internal flags common to both demuxer and muxer in the future. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* 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 AVStreamInternalAndreas Rheinhardt2021-09-17
| | | | | | | | | | Do this by allocating AVStream together with the data that is currently in AVStreamInternal; or rather: Put AVStream at the beginning of a new structure called FFStream (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVStreamInternal altogether.

* lavf: move AVStream.*index_entries* to AVStreamInternalAnton Khirnov2020-10-28
| | | | | | | Those are private fields, no reason to have them exposed in a public header. Since there are some (semi-)public fields located after these, even though this section is supposed to be private, keep some dummy padding there until the next major bump to preserve ABI compatibility.

* avformat: Remove unnecessary av_packet_unref()Andreas Rheinhardt2020-02-10
| | | | | | | | | Since bae8844e the packet will always be unreferenced when a demuxer returns an error, so that a lot of calls to av_packet_unref() in lots of demuxers are now redundant and can be removed.

* avformat: Forward errors where possibleAndreas Rheinhardt2019-12-12
| | | | | | | | | | 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.

|\ | | | | | | | | | | | | * commit '83548fe894cdb455cc127f754d09905b6d23c173': lavf: fix usage of AVIOContext.seekable Merged-by: James Almer <jamrial@gmail.com>
| * lavf: fix usage of AVIOContext.seekableAnton Khirnov2016-09-30
| | | | | | | | | | | | | | | | It is supposed to be a flag. The only currently defined value is AVIO_SEEKABLE_NORMAL, but other ones may be added in the future. However all the current lavf code treats this field as a bool (mainly for historical reasons). Change all those cases to properly check for AVIO_SEEKABLE_NORMAL.

| * lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.
