17ab836a5f libavcodec, libavdevice: Remove unnecessary includes of version.h
xvmc.h used FF_API_* macros before, but they were removed in
1c63aed232, leaving the include
unused.

The ones in android_camera.c and mediacodec_wrapper.c have been
added due to a misunderstanding, fixed in
c0bce367e4 and
13b77af2f0.

The one in mediacodec.c seems to never have been used at all.

because the call to the unavailable avpriv_mpegts_parse_packet()
is not optimized away. Therefore #if the offending code away

d61240f8c9 avcodec/packet_internal: Add proper PacketList struct
Up until now, we had a PacketList structure which is actually
a PacketListEntry; a proper PacketList did not exist
and all the related functions just passed pointers to pointers
to the head and tail elements around. All these pointers were
actually consecutive elements of their containing structs,
i.e. the users already treated them as if they were a struct.

So add a proper PacketList struct and rename the current PacketList
to PacketListEntry; also make the functions use this structure
instead of the pair of pointers.

d82c91ba2f configure, avcodec/Makefile: Add new mpeg4audio CONFIG_EXTRA group
This group is mainly for the users of *_mpeg4audio_get_config2();
it is not for those who only use avpriv_mpeg4audio_sample_rates.
This is in preparation for splitting the latter into a file of its own;
if there were no CONFIG_EXTRA group for *_mpeg4audio_get_config2()
users, one would have to add a dependency to the new file for all
these users on top of the existing dependency on mpeg4audio.o.

Adding a new CONFIG_EXTRA group only takes effect after a reconfigure;
so in order to force a reconfigure some unnecessary headers from
libavdevice/alldevices.c have been removed.

3d53cefb49 avcodec/raw: Reduce number of avpriv symbols
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.

e84d8ba441 avdevice/dshow: ensure pin's default format is set
Fixes regression in a1c4929f: there apparently are devices out there
that expose a pin default format that has parameters outside the
capabilities of any of the formats exposed on the pin (sic?). The
VirtualCam plugin (v 2.0.5) of OBS-Studio (v 27.1.3) is such a device.
Now when a default format was found, but not selected when iterating all
formats, fall back to directly setting the default format.

20b0d24c2f Makefile: Redo duplicating object files in shared builds
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.)

a1c4929f65 avdevice/dshow: select format with extended color info
Some DirectShow devices (Logitech C920 webcam) expose each DirectShow
format they support twice, once without and once with extended color
information. During format selection, both match, this patch ensures
that the format with extended color information is selected if it is
available, else it falls back to a matching format without such
information. This also necessitated a new code path taken for default
formats of a device (when user didn't request any specific video size,
etc), because the default format may be one without extended color
information when a twin with extended color information is also
available. Getting the extended color information when available is
important as it allows setting the color space, range, primaries,
transfer characteristics and chroma location of the stream provided by
dshow, enabling users to get more correct color automatically out of
their device.

937de260eb avdevice/dshow: set no-seek flags
avdevice/dshow is a realtime device and as such does not support
seeking. Therefore, its demuxer format should define the
AVFMT_NOBINSEARCH, AVFMT_NOGENSEARCH and AVFMT_NO_BYTE_SEEK flags.
With these flags set, attempting to seek (with, e.g.,
avformat_seek_file()) correctly yields -1 (operation not permitted)
instead of -22 (invalid argument).

This actually seems to apply to many other devices, at least the
gdigrab, v4l2, vfwcap, x11grab, fbdev, kmsgrab and android_camera
devices, from reading the source.

7dc33aad45 avdevice/dshow: implement option to use device video timestamps
The dshow avdevice ignores timestamps for video frames provided by the
DirectShow device, instead using wallclock time, apparently because the
implementer of this code had a device that provided unreliable
timestamps. Me (and others) would like to use the device's timestamps.
The new use_video_device_timestamps option for dshow device enables them
to do so. Since the majority of video devices out there probably provide
fine timestamps, this patch sets the default to using the device
timestamps, which means best fidelity timestamps are used by default.
Using the new option, the user can switch this off and revert to the old
behavior, so a fall back remains available in case the device provides
broken timestamps.

add use_video_device_timestamps to docs.

645f705d6a av(codec|device): Don't cast pointers to int
C99/C11 6.3.2.3 5: "Any pointer type may be converted to an integer
type. [...] If the result cannot be represented in the integer type,
the behavior is undefined." So stop casting pointers to int; use
uintptr_t instead.

db932241ee */version.h: define FF_API macros unconditionally
There is no reason to wrap them in #ifndef guards, they should only be

9b17273c77 avdevice/xv: Increase array size
av_image_copy() expects an array of four pointers according to its
declaration; although it currently only touches pointers that
are actually in use (depending upon the pixel format) this might
change at any time (as has already happened for the linesizes
in d7bc52bf45).

This fixes ticket #9264 as well as a warning from GCC 11.

fd101c9c3b avformat/internal: Move ff_read_line_to_bprint_overwrite to avio_internal.h
It only uses an AVIOContext and an AVBPrint.

When doing so, it turned out that several non-users of
ff_read_line_to_bprint_overwrite() and ff_bprint_to_codecpar_extradata()
relied on libavformat/internal.h to include bprint.h or avstring.h
for them. In order to avoid a repeat of this and in order to reduce
unnecessary dependencies, a forward declaration of struct AVBPrint is
used instead of including bprint.h.

b2d0826513 avdevice/pulse_audio_dec: do not read undersized frames
Keep on reading fragments until we got fragment_size amount of data, otherwise
we might get frames with 1-2 samples only if pa_stream_peek is called slightly
less frequently than sample rate.

Note that fragments might contain a lot less data than fragment_size, so
reading multiple fragments to get fragment_size amount of data is intentional.
