* avformat/movenc: write the colr atom by defaultMichael Bradshaw2020-08-21
| | | | | | | | | | | | | | | | | 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., http://ffmpeg.org/pipermail/ffmpeg-devel/2020-March/259334.html) This fixes https://trac.ffmpeg.org/ticket/7961 Signed-off-by: Michael Bradshaw <mjbshaw@google.com>
* avfilter/formats: Remove unused functionsAndreas Rheinhardt2020-08-21
| | | | | | | | | | | | | | 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 d1c49bcae9b7fd41df5c6804ac7f6a5c271a7c2e. And the one and only caller of ff_query_formats_all_layouts() (the asyncts filter) has been removed in commit a8fe8d6b4a35c95aa94fccde5f001041278d197c.

* avfilter/audio: Remove unused array, move used-only-once arrayAndreas Rheinhardt2020-08-21

* dnn_backend_native_layer_avgpool: Fix invalid assignment, use av_assertAndreas Rheinhardt2020-08-21
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* avfilter/vf_overlay: Remove superfluous ;Andreas Rheinhardt2020-08-21
| | | | | | | | | | | | | | | | 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.

* avfilter/fifo: Remove unused functions and headersAndreas Rheinhardt2020-08-21
| | | | | | | | | | | | | 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 b077d8d9082d057d4c7abd9e0b1a98f9651cfaa8 and channel_layout.h is since fdd9663781e3ebc8ebed0704607abd174095a905. Both headers have therefore been removed, too.

* avfilter/formats: Factor checking for mergeability out of ff_merge_*Andreas Rheinhardt2020-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Reviewed-by: Nicolas George <george@nsup.org> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avfilter/formats: Avoid code duplication when merging sampleratesAndreas Rheinhardt2020-08-20
| | | | | | | | | | 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. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
