* avformat/internal: Hide BSF stuff only used by the core APIsAndreas Rheinhardt2022-05-12
| | | | | | | | | | | | | | | | | | | | | The general demuxing API uses bitstream filters to extract extradata and the muxing API uses them in order to transform packets into the format desired by the target format. Therefore FFStream contains pointers to AVBSFContexts and lavf/internal.h includes lavc/bsf.h. Yet actually, only a few files files are supposed to use these, namely avformat.c, demux.c and mux.c. For all the other files, it should be an opaque type that they should not touch and that they need not know anything about. This can be achieved by not including these headers and using the structs instead of the corresponding typedefs. This also forces translation units that really use the BSF API themselves to include lavc/bsf.h directly instead of relying on indirect inclusions (a few other files also use the BSF API; they already abided by this). Of course, it also avoids unnecessary rebuilds when bsf.h changes. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/internal: Hide stuff only used by the core decode APIAndreas Rheinhardt2022-05-12
| | | | | | | | | | | | | | | | | | | | | | The general decoding API uses bitstream filters and an AVFifo and therefore AVCodecInternal contains pointers to an AVBSFContext and to an AVFifo and lavc/internal.h includes lavc/bsf.h and lavu/fifo.h. Yet actually, only two files are supposed to use these, namely avcodec.c and (mainly) decode.c. For all the other files, it should be an opaque type that they should not touch and that they need not know anything about. This can be achieved by not including these headers and using the structs instead of the corresponding typedefs. This also forces translation units that really use the BSF and the FIFO APIs themselves to include the relevant headers directly instead of relying on indirect inclusions (up until now, even avcodec.c and decode.c relied on fifo.h to be included by internal.h). Of course, it also avoids unnecessary rebuilds when bsf.h or fifo.h change. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/texturedspenc: Fix invalid shiftAndreas Rheinhardt2022-05-12
| | | | | | | | Left shifts of signed types are UB unless the results fit into the type. (Furthermore the value to be shifted need to be nonnegative.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* lavc: drop a confusing message about "thread emulation"Anton Khirnov2022-05-11
| | | | There is no such thing.
* lavc/pthread_frame: do not copy AVCodecInternal contentsAnton Khirnov2022-05-11
| | | | | None of its fields have meaningful values at that point that would need to be copied to frame thread workers.
* lavc/avcodec: only allocate decoding packets for decodersAnton Khirnov2022-05-11
|
* lavc/encode: add an encoder-specific get_buffer() variantAnton Khirnov2022-05-11
| | | | | | | | | | | Several encoders (roqvideo, svq1, snow, and the mpegvideo family) currently call ff_get_buffer(). However this function is written assuming it is called by a decoder. Though nothing has been obviously broken by this until now, that may change in the future. To avoid potential future issues, introduce a simple encode-specific wrapper around avcodec_default_get_buffer2() and enforce its use in encoders.
* lavc/snow: only allocate mconly_picture for decodingAnton Khirnov2022-05-11
| | | | It is not used in the encoder.
* doc/ffmpeg: fix typo in ffmpeg.texiNetSysFire2022-05-10

* avfilter/avfilter: Fix compilation with TRACE definedAndreas Rheinhardt2022-05-10
| | | | | | | | av_get_pix_fmt_name() is used in an ff_tlog(), which is only compiled if TRACE is defined. Fixes a regression caused by f2b79c5b855b7450c8f3c15b9ec11b439cd2a294. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/utils: Move ff_format_io_close.* to options.c, avformat.cAndreas Rheinhardt2022-05-10
| | | | | | | These are not pure avio-functions, but auxiliary AVFormatContext functions. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/utils: Move avpriv_set_pts_info() to avformat.cAndreas Rheinhardt2022-05-10
| | | | | | It is an essential auxiliary function for both demuxing and muxing. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/utils: Move ff_copy_whiteblacklists to avformat.cAndreas Rheinhardt2022-05-10
| | | | | | This is an auxiliary function for AVFormatContexts. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/utils: Move ff_format_set_url to avformat.cAndreas Rheinhardt2022-05-10
| | | | | | | An auxiliary function for AVFormatContexts (mainly muxers, but potentially (e.g. rtsp) also demuxers). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/utils: Move ff_is_intra_only to avformat.cAndreas Rheinhardt2022-05-10
| | | | | | | It is an auxiliary function only used by the generic muxing and demuxing code. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/utils: Move ff_find_stream_index to demux_utils.cAndreas Rheinhardt2022-05-10
| | | | | | | It is only used by demuxers (and it is generally demuxers who have to translate format-specific IDs to stream indices). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/asf: Move ASF GUIDs to a new fileAndreas Rheinhardt2022-05-10
| | | | | | | | | | | They are also needed by the MMSH and MMST protocols and therefore the file they are in is pulled in when these protocols are enabled and used. By moving them to a separate file, linking statically to libavformat while only using AVIO no longer pulls in all the muxers/demuxers (and also no longer any AVCodecs when linking statically to libavcodec). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/utils: Move av_find_best_stream to avformat.cAndreas Rheinhardt2022-05-10
| | | | | | | | | It is not forbidden to call this with a muxer, so it is moved to avformat.c and not demux_utils.c. ff_find_decoder(), which is used by av_find_best_stream() is also moved as well, despite being even more geared towards demuxers. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/utils: Move av_find_default_stream_index to avformat.cAndreas Rheinhardt2022-05-10
| | | | | | | | While it is clearly written with demuxers in mind, it is not forbidden to call it with muxers, hence avformat.c and not demux_utils.c. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/utils: Move av_find_program_from_stream to avformat.cAndreas Rheinhardt2022-05-10
| | | | | | It is potentially used with both demuxers and muxers. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/utils: Move guessing frame rate/SAR to avformat.cAndreas Rheinhardt2022-05-10
| | | | | | | | | It is not explicitly forbidden to call these functions with muxers (although it is probably intended to be only called by demuxers; av_guess_sample_aspect_ratio even says that "the stream aspect ratio is set by the demuxer"). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/utils: Move matching stream specificiers to avformat.cAndreas Rheinhardt2022-05-10

* avformat/utils: Move ff_get_extradata to demux_utils.cAndreas Rheinhardt2022-05-10
| | | | | | | | It is only used by demuxers (although it is hypothetically possible that some day e.g. a protocol might need it, but that is unlikely given that they don't deal with AVCodecParameters). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/internal: Make AVFormatContext* a logctx in ff_get_extradataAndreas Rheinhardt2022-05-10
| | | | | | | I.e. use void* instead of AVFormatContext*, because it is only used for logging. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/utils: Move ff_add_attached_pic to demux_utils.cAndreas Rheinhardt2022-05-10
| | | | | | | It is demuxer-only: It potentially adds an AVStream and it sets AVStream.attached_pic. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/utils: Move avformat_queue_attached_pictures to demux_utils.cAndreas Rheinhardt2022-05-10

* avformat/utils: Move av_format_inject_global_side_data to demux_utils.cAndreas Rheinhardt2022-05-10
| | | | | | | This function is only intended for demuxers (as calling it doesn't have any observable effect for a muxer). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/utils: Move avpriv_new_chapter to demux_utils.cAndreas Rheinhardt2022-05-10
| | | | | | | It is demuxer-only: Muxers deal only with chapters given to them; they don't create any of their own. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
