* avutil: remove deprecated FF_API_FRAME_PKTJames Almer2025-03-281-10/+0
| | | | | | Deprecated since 2023-03-20. Signed-off-by: James Almer <jamrial@gmail.com>
* lavd/lavfi: stop using avfilter_graph_create_filter() incorrectlyAnton Khirnov2024-09-281-6/+12

* avformat/internal: Move FF_FMT_INIT_CLEANUP to demux.hAndreas Rheinhardt2024-03-261-1/+1
| | | | | | | | | 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 Rheinhardt2024-03-071-5/+6
| | | | | | | | | | | | | | | | | | | | | 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.

* avdevice/lavfi: Fix double-free on errorAndreas Rheinhardt2023-09-301-4/+5
| | | | | | | | | | | After the AVFrame has been wrapped into a buffer, it is owned by the buffer and must not be freed manually any more. Yet this happens on subsequent errors. This bug was introduced in 6ca43a9675d651d7ea47c7ba2fafb1bf831c4d0b. Reviewed-by: Timo Rothenpieler <timo@rothenpieler.org> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* lavu/frame: deprecate AVFrame.pkt_{pos,size}Anton Khirnov2023-03-201-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | These fields are supposed to store information about the packet the frame was decoded from, specifically the byte offset it was stored at and its size. However, - the fields are highly ad-hoc - there is no strong reason why specifically those (and not any other) packet properties should have a dedicated field in AVFrame; unlike e.g. the timestamps, there is no fundamental link between coded packet offset/size and decoded frames - they only make sense for frames produced by decoding demuxed packets, and even then it is not always the case that the encoded data was stored in the file as a contiguous sequence of bytes (in order for pos to be well-defined) - pkt_pos was added without much explanation, apparently to allow passthrough of this information through lavfi in order to handle byte seeking in ffplay. That is now implemented using arbitrary user data passthrough in AVFrame.opaque_ref. - several filters use pkt_pos as a variable available to user-supplied expressions, but there seems to be no established motivation for using them. - pkt_size was added for use in ffprobe, but that too is now handled without using this field. Additonally, the values of this field produced by libavcodec are flawed, as described in the previous ffprobe conversion commit. In summary - these fields are ill-defined and insufficiently motivated, so deprecate them.
* avdevice/lavfi: pass forward video framerateTimo Rothenpieler2022-07-181-0/+5
|
* avdevice/lavfi: output wrapped AVFramesTimo Rothenpieler2022-07-181-54/+35
| | | | | | | | | | | | | This avoids an extra copy of potentially quite big video frames. Instead of copying the entire frames data into a rawvideo packet it packs the frame into a wrapped avframe packet and passes it through as-is. Unfortunately, wrapped avframes are set up to be video frames, so the audio frames continue to be copied. Additionally, this enabled passing through video frames that previously were impossible to process, like hardware frames or other special formats that couldn't be packed into a rawvideo packet.
