* avformat/mux: Add flag for "not more than one stream of each type"Andreas Rheinhardt2024-03-221-3/+2
| | | | | | | | | | | | | | | | More exactly: Not more than one stream of each type for which a default codec (i.e. AVOutputFormat.(audio|video|subtitle)_codec) is set; for those types for which no such codec is set (or for which no designated default codec in AVOutputFormat exists at all) no streams are permitted. Given that with this flag set the default codecs become more important, they are now set explicitly to AV_CODEC_ID_NONE for "unset"; the earlier code relied on AV_CODEC_ID_NONE being equal to zero, so that default static initialization set it accordingly; but this is not how one is supposed to use an enum.

* avformat/avformat: Avoid including codec.h, frame.hAndreas Rheinhardt2023-09-071-0/+1
| | | | | | | | | | | | | | | | AVCodec is only ever used as an incomplete type (i.e. via a pointer to an AVCodec) in avformat.h and it is not really part of the core of avformat.h or libavformat; almost none of our internal users make use of it (and none make use of hwcontext.h, which is implicitly included). So switch to use struct AVCodec, but continue to include codec.h for external users for compatibility. Also, do the same for AVFrame and frame.h, which is implicitly included by codec.h (via lavu/hwcontext.h). Also, remove an unnecessary inclusion of <time.h>.

* avformat/avformat: Move AVOutputFormat internals out of public headerAndreas Rheinhardt2023-02-091-6/+7
| | | | | | | | | | | | | | This commit does for AVOutputFormat what commit 20f972701806be20a77f808db332d9489343bb78 did for AVCodec: It adds a new type FFOutputFormat, moves all the internals of AVOutputFormat to it and adds a now reduced AVOutputFormat as first member. This does not affect/improve extensibility of both public or private fields for muxers (it is still a mess due to lavd).

* avformat/yuv4mpegenc: Simplify writing global and packet headersAndreas Rheinhardt2020-09-041-14/+7
| | | | | | | | | | | | | | YUV4MPEG writes a string as header for both the file itself as well as for every frame; these strings contain magic strings and these were up until now included in the string to write via %s. Yet they are compile time constants, so one can use the compile-time string concatentation instead of inserting these strings at runtime. Furthermore, the global header has been written via snprintf() to a local buffer first before writing it. This can be simplified by using avio_printf().

| * lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-231-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * lavf: switch to AVStream.time_base as the hint for the muxer timebaseAnton Khirnov2014-06-181-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | Previously, AVStream.codec.time_base was used for that purpose, which was quite confusing for the callers. This change also opens the path for removing AVStream.codec. The change in the lavf-mkv test is due to the native timebase (1/1000) being used instead of the default one (1/90000), so the packets are now sent to the crc muxer in the same order in which they are demuxed (previously some of them got reordered because of inexact timestamp conversion).
