* avformat/matroskaenc: Disable MKV-only code if MKV muxer is disabledAndreas Rheinhardt2022-01-08
| | | | | | | | The Matroska muxer has quite a lot of dependencies and lots of them are unnecessary for WebM. By disabling the Matroska-only code at compile time one can get rid of them. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat: reuse the common code for v210/v210xLimin Wang2022-01-05
| | | | | | | | As suggested by Andreas Rheinhardt, most code of v210 demuxer is common code which is duplicated from rawvideodec, so it's better to move v210/v210x demuxer code to rawvideodec.c and reuse the common code. Signed-off-by: Limin Wang <lance.lmwang@gmail.com>
* avcodec/utils: Unavpriv avpriv_toupper4()Andreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | | This function is quite small (96B with GCC 11.2 on x64 Ubuntu 21.10 at -O3), making it more economical to duplicate it into libavformat instead of exporting it as avpriv: Doing so saves 2x24B in .dynsim, 2x16B in .dynstr, 2x2B .gnu.version, 24B in .rela.plt, 16B in .plt, 16B in .plt.sec (if enabled), 4B .gnu.hash; besides the actual duplicated code this also adds 2x8B .eh_frame_hdr and 24B .eh_frame. In other words: Duplicating is neutral size-wise (it is also presumed neutral for other systems). Given that it avoids the runtime overhead of dynamic symbols, it is advantageouos to duplicate the function. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpegaudiodata: Unavpriv mpa_bitrate and mpa_frequency tabsAndreas Rheinhardt2022-01-04
| | | | | | | | | | | These arrays have a size of 180 resp. six bytes. This does not make it worthwhile to export them due to the overhead this occurs; for x64 Elf/Linux/GNU: 2x2B version, 2x24B .dynsym, 24B .rela.dyn, 8B .got, 4B hash + twice the size of the name (here 20+23B). Therefore these symbols are unavprived and duplicated for shared builds. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpeg4audio: Unavpriv and deduplicate mpeg4audio_sample_ratesAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | | | | | | | avpriv_mpeg4audio_sample_rates has a size of 64B and it is currently avpriv; a clone of it exists in aacenctab.h and from there it is inlined in aacenc.c (which also uses the avpriv version) and in the FLV muxer. This means that despite it being avpriv both libavformat as well as libavcodec have copies already. This situation is clearly suboptimal. Given the overhead of exporting symbols (for x64 Elf/Linux/GNU: 2x2B version, 2x24B .dynsym, 24B .rela.dyn, 8B .got, 4B hash + twice the size of the name (here 31B)) the object is unavprived, i.e. duplicated into libavformat when creating a shared build; but the duplicates in the AAC encoder and FLV muxer are removed. This involves splitting of the sample rate table into a file of its own; this allowed to break some spurious dependencies (e.g. both the AAC encoder as well as the Matroska demuxer actually don't need the mpeg4audio_get_config stuff).

* avcodec/jpegtables: Unavpriv MJPEG-tablesAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | | There are seven MJPEG-tables, five small (1x12, 4x17) and two not small (2x162). These are all avpriv, despite this not being worthwhile due to the overhead of exporting a symbol: The total overhead for each symbol consists of two entries in .dynsym (24B each), one entry in the importing library's .rela.dyn (24B) and one in .got (8B) as well as 2x2B for symbol versions and 4B for symbol hashes in the exporting library; in addition to that, the name of the symbol is included in both exporting and importing libraries, using 2x210 bytes in this case. (The above numbers are for a x64 Elf/Linux/GNU system. Other platforms will give different numbers.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/dca: Unavpriv dca_sample_ratesAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | Said table is 64 bytes long and exported so that it can be used both in libavcodec and libavformat. This commit stops doing so and instead duplicates it for shared builds, because the overhead of exporting the symbol is bigger than 64 bytes. It consists of the length of the name of the symbol (2x24 bytes), two entries in .dynsym (2x24 bytes), two entries for symbol version (2x2 bytes), one hash value in the exporting library (4 bytes) in addition to one entry in the importing library's .got and .rela.dyn (8 + 24 bytes). (The above numbers are for a Linux/GNU/Elf system; the numbers for other platforms may be different.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/ac3tab: Unavpriv ac3_channel_layout_tabAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | | | It is small (16 B) and therefore the overhead of exporting it more than outweighs the size savings from not having duplicated symbols: When the symbol is no longer avpriv, one saves twice the size of the string containing the symbols name (2x30 byte), two entries in .dynsym (24 bytes each on x64), one entry in the importing libraries .got and .rela.dyn (8 + 24 bytes on x64) and two entries for the symbol version (2 bytes each) and one hash value in the exporting library (4 bytes). (The exact numbers are of course different for other platforms (e.g. when using dlls), but given that the strings saved alone more than outweigh the array size it can be presumed that this is beneficial for all platforms.)

* Makefile: Redo duplicating object files in shared buildsAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case of shared builds, some object files containing tables are currently duplicated into other libraries: log2_tab.c, golomb.c, reverse.c. The check for whether this is duplicated is simply whether CONFIG_SHARED is true. Yet this is crude: E.g. libavdevice includes reverse.c for shared builds, but only needs it for the decklink input device, which given that decklink is not enabled by default will be unused in most libavdevice.so. This commit changes this by making it more explicit about what to duplicate from other libraries. To do this, two new Makefile variables were added: SHLIBOBJS and STLIBOBJS. SHLIBOBJS contains the objects that are duplicated from other libraries in case of shared builds; STLIBOBJS contains stuff that a library has to provide for other libraries in case of static builds. These new variables provide a way to enable/disable with a finer granularity than just whether shared builds are enabled or not. E.g. lavd's Makefile now contains: SHLIBOBJS-$(CONFIG_DECKLINK_INDEV) += reverse.o Another example is provided by the golomb tables. These are provided by lavc for static builds, even if one uses a build configuration that makes only lavf use them. Therefore lavc's Makefile contains STLIBOBJS-$(CONFIG_MXF_MUXER) += golomb.o, whereas lavf's Makefile has a corresponding SHLIBOBJS-$(CONFIG_MXF_MUXER) += golomb_tab.o. E.g. in case the MXF muxer is the only component needing these tables only libavformat.so will contain them for shared builds; currently libavcodec.so does so, too. (There is currently a CONFIG_EXTRA group for golomb. But actually one would need two groups (golomb_avcodec and golomb_avformat) in order to know when and where to include these tables. Therefore this commit uses a Makefile-based approach for this and stops using these groups for the users in libavformat.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/utils: Move demuxing code out into a new fileAndreas Rheinhardt2021-09-17
| | | | | | | | | | | | | libavformat/utils.c has over 4800 lines and is supposed to contain "various utility functions for use within FFmpeg". In reality it contains all that and the whole demuxing core of libavformat. This is especially bad, because said file includes the FFMPEG_VERSION (the git commit sha) so that it is rebuilt whenever the commit HEAD points to changes. Therefore this commit makes it smaller by moving the demuxing code out to a new file, demux.c (in analogy to mux.c for the muxing code).

Also remove the isom.h header; and while just at it, remove an unused mathematics.h inclusion. (isom.c actually depends upon mpeg4audio from libavcodec for avpriv_mpeg4audio_get_config2 and avpriv_mpa_freq_tab; yet there is no configure dependency for iso_media which leads to failure of shared builds.)
