* avformat/avformat: Move AVOutputFormat internals out of public headerAndreas Rheinhardt2023-02-09
| | | | | | | | | | | | | | 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/internal: Don't include avcodec.hAndreas Rheinhardt2022-09-26
| | | | | | | | | | | | | | | The general demuxing API uses parsers and decoders. Therefore FFStream contains pointers to AVCodecContexts and AVCodecParserContext and lavf/internal.h includes lavc/avcodec.h. Yet actually only a few files files really use these; and it is best when this number stays small. Therefore this commit uses opaque structs in lavf/internal.h for these contexts and stops including avcodec.h. This also avoids including lavc/codec_desc.h implicitly. All other headers are implicitly included as now (mostly through codec.h). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/avio: Move internal AVIOContext fields to avio_internal.hAndreas Rheinhardt2021-08-25
| | | | | | | | | | | | | | Currently AVIOContext's private fields are all over AVIOContext. This commit moves them into a new structure in avio_internal.h instead. Said structure contains the public AVIOContext as its first element in order to avoid having to allocate a separate AVIOContextInternal which is costly for those use cases where one just wants to access an already existing buffer via the AVIOContext-API. For these cases ffio_init_context() can't fail and always returned zero, which was typically not checked. Therefore it has been made to not return anything.

* avformat/riffenc: indicate storage of flipped RGB bitmapsGyan Doshi2020-07-15
| | | | | | | | | | | | | Some legacy applications such as AVI2MVE expect raw RGB bitmaps to be stored bottom-up, whereas our RIFF BITMAPINFOHEADER assumes they are always stored top-down and thus write a negative value for height. This can prevent reading of these files. Option flipped_raw_rgb added to AVI and Matroska muxers which will write positive value for height when enabled. Note that the user has to flip the bitmaps beforehand using other means such as the vflip filter.
* avformat: convert some avio_flush() calls to ↵Marton Balint2020-01-07
| | | | | | | | | | | | | | | | | avio_write_marker(AVIO_DATA_MARKER_FLUSH_POINT) Converting explicit avio_flush() calls helps us to buffer more data and avoid flushing the IO context too often which causes reduced IO throughput for non-streamed file output. The user can control FLUSH_POINT flushing behaviour using the -flush_packets option, the default typically means to flush unless a non-streamed file output is used, so this change should have no adverse effect on streaming even if it is assumed that after an avio_flush() the output buffer is clean so small seekbacks within the output buffer will work even when the IO context is not seekable. Signed-off-by: Marton Balint <cus@passwd.hu>
* avformat: remove more unneeded avio_flush() callsMarton Balint2020-01-07
| | | | | | | | | | | | These instances are simply redundant or present because avio_flush() used to be required before doing a seekback. That is no longer the case, aviobuf code does the flush automatically on seek. This only affects code which is either disabled for streaming IO contexts or does no seekbacks after the flush, so this change should have no adverse effect on streaming. Signed-off-by: Marton Balint <cus@passwd.hu>
* avformat: remove avio_flush() calls from the end of write_header functionsMarton Balint2020-01-07
| | | | | | | | | | | | | | To make it consistent with other muxers. The user can still control the generic flushing behaviour after write_header (same way as after packets) using the -flush_packets option, the default typically means to flush unless a non-streamed file output is used. Therefore this change should have no adverse effect on streaming, even if it is assumed that the first packet has a clean buffer, so small seekbacks within the output buffer work even when the IO context is not seekable.

* 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.

| | | | | | | | | | | | | | | | 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.

| * lavf: Replace the ASF demuxerAlexandra Hájková2015-06-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old one is the result of the reverse engineering and guesswork. The new one has been written following the now-available specification. This work is part of Outreach Program for Women Summer 2014 activities for the Libav project. The fate references had to be changed because the old demuxer truncates the last frame in some cases, the new one handles it properly. The seek-test reference is changed because seeking works differently in the new demuxer. When seeking, the packet is not read from the stream directly, but it is rather constructed by the demuxer. That is why position is -1 now in the reference. Signed-off-by: Anton Khirnov <anton@khirnov.net>
