The dvbsubtest_filter.ts sample is a filtered version of the Videolan
sample database (samples/sub/dvbsub/dvbsubtest.ts) using Project X. It
originates from ticket #8844.
The write_colr flag has been marked as experimental for over 5 years.
It should be safe to enable its behavior by default as follows:
- Write the colr atom by default for mp4/mov if any of the following:
- The primaries/trc/matrix are all specified, OR
- There is an ICC profile, OR
- The user specified +write_colr
- Keep the write_colr flag for situations where the user wants to
write the colr atom even if the color info is unspecified (e.g.,

This commit removes ff_parse_sample_format(), ff_parse_time_base() and
ff_query_formats_all_layouts() from libavfilter/formats.c. All of these
functions were completely unused. ff_parse_time_base() has not been used
at all since it had been added in 3448404a707b6e236a2ffa7b0453b3300de41b7b;
the last caller of ff_parse_sample_format has been removed in commit
d1c49bcae9. And the one and only caller of
ff_query_formats_all_layouts() (the asyncts filter) has been removed in
commit a8fe8d6b4a.

ff_planar_sample_fmts_array is unused (and was unused since it was added
in 4d4098da00) and therefore this commit
removes it; ff_packed_sample_fmts_array meanwhile is used only once (in
the amerge filter) and therefore it has been moved to this place.

dnn_execute_layer_avg_pool() contains the following line:
assert(avgpool_params->padding_method = VALID);
This statement contains an assignment where obviously a comparison was
intended. Furthermore, *avgpool_params is const, so that the attempted
assignment leads to a compilation failure if asserts are enabled
(i.e. if DEBUG is defined which leads libavutil/internal.h to not define
NDEBUG). Moreover, the enumeration constant VALID actually has the value 0,
so that the assert would be triggered if a compiler compiles this with
asserts enabled. Finally, the statement uses assert() directly instead
of av_assert*().
All these errors have been fixed.
Thanks to ubitux for providing a FATE-box [1] where DEBUG is defined.

In a function body, a redundant ; is just a null statement that does
nothing. Yet outside a function body, a superfluous ';' like one that
exists if one adds a ';' immediately after a function body's closing
brace is actually invalid C that compilers happen to accept. Yet when
compiled in -pedantic mode, both GCC as well as Clang emit warnings for
this like "ISO C does not allow extra ‘;’ outside of a function
[-Wpedantic]".
The scenario described above existed in vf_overlay.c as a result of
macro expansion. This commit fixes it.

The functions were forgotten in 03c8fe49ea3f2a2444607e541dff15a1ccd7f0c2;
removing them also means that the avassert.h and samplefmt.h headers are
no longer used any more, so they have been removed, too.
Moreover, video.h is unused since b077d8d908
and channel_layout.h is since fdd9663781.
Both headers have therefore been removed, too.

The callers of the ff_merge_*() functions fall into two categories with
quite different needs:
One caller is can_merge_formats() which only wants to test for mergeability
without it merging anything. In order to do so, it duplicates the lists
it intends to test and resets their owners so that they are not modified
by ff_merge_*(). It also means that it needs to receive the merged list
(and not only an int containing whether the lists are mergeable) to
properly free it.
The other callers want the lists to be actually merged. But given the
fact that ff_merge_*() automatically updates the owners of the lists,
they only want the information whether the merge succeeded or not; they
don't want a link to the new list.
Therefore this commit splits these functions in two: ff_merge_*() for
the latter callers and ff_can_merge_*() for the former.
ff_merge_*() doesn't need to return a pointer to the combined list at all
and hence these functions have been modified to return an int, which
allows to distinguish between incompability and memory allocation failures.
ff_can_merge_*() meanwhile doesn't modify its arguments at all obviating
the need for copies. This in turn implies that there is no reason to
return a pointer to the new list, as nothing needs to be freed. These
functions therefore return an int as well. This allowed to completely
remove can_merge_formats() in avfiltergraph.c.
Notice that no ff_can_merge_channel_layouts() has been created, because
there is currently no caller for this. It could be added if needed.

Right now, ff_merge_samplerates() contains three instances of the
MERGE_REF() macro, a macro which reallocates an array, updates some
pointers in a loop and frees several buffers. This commit makes it
possible to contain only one instance of said macro in the function,
thereby reducing codesize.

In listener mode the first fd is not closed when libsrt_close() is called
because it is overwritten by the new accept fd. Added the listen_fd to the
context to properly close it when libsrt_close() is called.
