* avformat/movenc: Use dedicated pointer for access to MOVTrackAndreas Rheinhardt2022-01-04
| | | | | | | | | Improves readability and slightly decreases codesize. While just at it, also remove a check whether the packet list is nonempty before freeing it, as freeing an empty list is fine and basically a no-op. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* 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/(aiff|flac|mov|mp3|tta)enc: Don't create unnecessary referencesAndreas Rheinhardt2022-01-04
| | | | | | | | | The packet given to muxers is not used afterwards; it is always unreferenced by libavformat. Ergo muxers are allowed to keep the references in the packets and e.g. move the ownership to a packet list. This is what this commit does.

* avformat/matroska{dec, enc}: Parse BlockAdditionMapping elementsquietvoid2022-01-04
| | | | | | | | | | | | | Adds handling of dvcC/dvvC block addition mappings. The parsing creates AVDOVIDecoderConfigurationRecord side data. The configuration block is written when muxing into Matroska, if DOVI side data is present for the track. Most of the Matroska element parsing is based on Plex's FFmpeg source code.

* avformat/dovi_isom: Implement Dolby Vision configuration parsing/writingquietvoid2022-01-04
| | | | | | | | | | | | | | Both parse/write implementations are based on mov/movenc. This only adds support for the "Dolby Vision configuration box". Other configuration boxes, such as "Dolby Vision enhancement layer configuration box" are not supported. The new functions will be used to implement parsing/writing the DOVI config for Matroska, as well as to refactor both mov/movenc to use dovi_isom functions.

* avformat/mov: add option max_stts_deltaGyan Doshi2021-12-31
| | | | | | | | | | | | | | | | Very high stts sample deltas may occasionally be intended but usually they are written in error or used to store a negative value for dts correction when treated as signed 32-bit integers. This option lets the user set an upper limit, beyond which the delta is clamped to 1. Values greater than the limit if negative when cast to int32 are used to adjust onward dts. Unit is the track time scale. Default is UINT_MAX - 48000*10 which allows upto a 10 second dts correction for 48 kHz audio streams while accommodating 99.9% of uint32 range.
