* lib*/version: Move library version functions into files of their ownAndreas Rheinhardt2022-05-10
| | | | | | | This avoids having to rebuild big files every time FFMPEG_VERSION changes (which it does with every commit). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* Keep including the full version.h when headers are included externallyMartin Storsjö2022-03-19
| | | | | | | | | This avoids unnecessary churn and build breakage for users, by making sure the whole version.h is included like it has been so far, while keeping the benefit of not needing to rebuild most files in the ffmpeg tree on minor/micro bumps.

* 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>

* libswresample/swresamplec: Err num(negative-size) was used as a function ↵Yu Yang2021-12-09

* swresample/swresample: Remove array size hint from swr_convert()Andreas Rheinhardt2021-12-03
| | | | | | | | | | | | | | SWR_CH_MAX is internal only and the arrays are therefore not required to have that many elements (and they typically don't do it). So remove this potentially confusing hint. (Newer versions of GCC emit -Warray-parameter= warnings for this, because the definition with explicit size differs from the declaration (which leaves the size unspecified); this is IMO a false-positive, because definition and declaration didn't conflict, but anyway it is fixed by this commit.)

* swresample/rematrix: handle 22.2 as a 9 channel layoutJan Ekström2020-08-18
| | | | | | | | | | | This is as far as 22.2 follows the same channel order as WaveFormatExtensible's channel mask (and the AV_CH_* defines). After LFE2 the side channels would follow, but that offset of one stops us from utilizing them without further tweaks. This change was verified by using swresample to downmix to 5.1, and then feeding that to WASAPI.
* swresample/rematrix: treat 22.2 as 5.1 (back) when mixingJan Ekström2020-08-04
| | | | | | | | | Only this sub-set of channels actually follows the bit mask order in the official 22.2 channel mapping. Additionally, the 5.1 channels are there for backwards compatibility with the previous system. This enables the utilization of 22.2 content until a proper down/up matrix is added into swresample.
* swresample/matrix: switch internal clean_layout function to not drop high bitsJan Ekström2020-08-04
| | | | | | These bits are utilized by channel layouts such as 22.2. If those are dropped, the returned channel layout is no longer a match against the AV_CH_LAYOUT define when returned from this function.

* swresample: Use channel count in rematrix initializationMarcin Gorzel2018-07-26
| | | | | | | | Rematrixing supports up to 64 channels. However, there is only a limited number of channel layouts defined. Since the in/out channel count is currently obtained from the channel layout, for undefined layouts (e.g. for 9, 10, 11 channels etc.) the rematrixing fails. This patch changes rematrix init methods to use in (used) and out channel count directly instead of computing it from channel layout. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* swresample/arm: remove unintentional relocation.Rahul Chaudhry2018-04-19
| | | | | | | | | | | | | | | | | | Branch to global symbol results in reference to PLT, and when compiling for THUMB-2 - in a R_ARM_THM_JUMP19 relocation. Some linkers don't support this relocation (ld.gold), while others can end up truncating the relocation to fit (ld.bfd). Convert this branch through PLT into a direct branch that the assembler can resolve locally. See https://github.com/android-ndk/ndk/issues/337 for background. The current workaround is to disable neon during gstreamer build, which is not optimal and can be reverted after this patch: https://github.com/freedesktop/gstreamer-cerbero/commit/41556c415739fbc3a72c7eaee7e70a565b719b2f Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| | | | | | | | | | | | | | | | | | | | | | | | | | | * commit '07a2b155949eb267cdfc7805f42c7b3375f9c7c5': Bump major versions of all libraries A few API deprecated ~2 years ago or more are also postponed here for varying reasons. FF_API_LOWRES: Since this functionality depends on AVStream->codec, i figure the two can be removed at the same time in the next bump or so. FF_API_AVCTX_TIMEBASE: Couldn't get this one to work. Not just libavcodec but apparently also libavformat and ffmpeg.c expect AVCodecContext->time_base to be set for decoding. Upon removal some tests report a different generic stream time base (like 1/25), and others lose packet duration values. I guess it's somehow tied to the AVStream->codec clusterfuck. It can be dealt with alongside FF_API_LAVF_AVCTX in the next bump. FF_API_OLD_FILTER_OPTS_ERROR: This one is meant to remain after FF_API_OLD_FILTER_OPTS is removed. Its purpose is displaying the corrected command line using the new syntax as a suggestion as part of the error message. Merged-by: James Almer <jamrial@gmail.com>
