* 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/utils: Move ff_get_packet_palette() to rawutils.cAndreas Rheinhardt2022-05-10
| | | | | | | | | | ff_get_packet_palette() and ff_reshuffle_raw_rgb() belong together: E.g. the former takes the return value of the latter as argument. So move ff_get_packet_palette() to rawutils.c (which consists solely of ff_reshuffle_raw_rgb()). Also add a separate header for these two functions.

* avcodec/raw: Reduce number of avpriv symbolsAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libavcodec currently exports four avpriv symbols that deal with PixelFormatTags: avpriv_get_raw_pix_fmt_tags, avpriv_find_pix_fmt, avpriv_pix_fmt_bps_avi and avpriv_pix_fmt_bps_mov. The latter two are lists of PixelFormatTags, the former returns such a list and the second searches a list for a pixel format that matches a given fourcc; only one of the aforementioned three lists is ever searched. Yet for avpriv_pix_fmt_bps_avi, avpriv_pix_fmt_bps_mov and avpriv_find_pix_fmt the overhead of exporting these functions actually exceeds the size of said objects (at least for ELF; the following numbers are for x64 Ubuntu 20.10): The code size of avpriv_find_pix_fmt is small (GCC 10.2 37B, Clang 11 41B), yet exporting it adds a 20B string for the name alone to the exporting as well as to each importing library; there is more: Four bytes in the exporting libraries .gnu.hash; two bytes each for the exporting as well as each importing libraries .gnu.version; 24B in the exporting as well as each importing libraries .dynsym; 16B+24B for an entry in .plt as well as the accompanying relocation entry in .rela.plt for each importing library. The overhead for the lists is similar: The strings are 23B and the .plt+.rela.plt pair is replaced by 8B+24B for an entry in .got and a relocation entry in .rela.dyn. These lists have a size of 80 resp. 72 bytes. Yet for ff_raw_pix_fmt_tags, exporting it is advantageous compared to duplicating it into libavformat and potentially libavdevice. Therefore this commit replaces all library uses of the four symbols with a single function that is exported for shared builds. It has an enum parameter to choose the desired list besides the parameter for the fourcc. New lists can be supported with new enum values. Unfortunately, avpriv_get_raw_pix_fmt_tags could not be removed, as the fourcc2pixfmt tool uses the table of raw pix fmts. No other user of this function remains.

* 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: 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.

| | | | | | | | | | | | Writes one set of field framing information for progressive streams and two sets for interlaced streams. Fixes ticket #6383. Unfortunately the OpenDML v1.02 document is not very specific on what value to use for start_line when frame data is not coming from a capturing device, so this is just using 0/1 depending on the field order as a best-effort guess.

| | | | | | | | | | | | | | | | 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.
* | avformat/avienc: add reserve_index_space optionTobias Rapp2017-01-31
| | | | | | | | | | | | | | | | | | | | Allows the user to reserve space for the ODML master index. A sufficient sized master index in the AVI header avoids storing follow-up master indexes within the 'movi' data later.

| * 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.
