Any alternative? > > Tests in the library's test folder can and usually include the actual .c > file from the module they are testing, so making it static will work fine. Ok. To summarize: - functions used only by "imf_.c" should be static in "imf_.c, and tests should include "imf_.c" - any function/structure used by both "imf_.c" and "imf_.c" should be declared in "imf.h", even if the function/structure is not intended to be used beyond "imf_.c" and "imf_.c" In other words, splitting imf-related functions into "imf.h" (functions potentially for use beyond the IMF demuxer) and "imf_internal.h" (functions not for use beyond the IMF demuxer) is not desirable. Ok? Happy either way, just want to make sure I get the next patch version right :) > ___ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email > ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe". ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".

On 10/31/2021 3:34 PM, Pierre-Anthony Lemieux wrote: The functions are not static and are defined in imf_internal.h. They are used in both libavformat/imfdec.c and the tests at libavformat/tests/imf.c. Ok? If they are used in libavformat only it should be static. AFAIK static functions are only available in the compilation unit where they are defined, so if a static function (e.g. `parse_imf_asset_map_from_xml_dom()`) is defined in libavformat/imf_dec.c, it will not be available in libavformat/tests/imf.c. Functions that can be used by other FFMPEG modules are declared in "imf.h", whereas functions that are intended to be used only by the IMF demuxer are declared in "imf_internal.h". For example, both "libavformat/tests/imf.c" and "libavformat/imfdec.c" include "libavformat/imf_internal.h" so they can access `parse_imf_asset_map_from_xml_dom()`. Does that work? Any alternative? Tests in the library's test folder can and usually include the actual .c file from the module they are testing, so making it static will work fine. ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".

From: Roman Arzumanyan

Here's my revised version of the patch.
It brings its order of operation much more in line with normal scale/scale2ref.
Also gets rid of differences in option parsing between the 2ref and non-2ref
version of the filters.
I also added some more options, like the eval option or size, size it was used
anyway, just not exposed.
If no further issues or comments arise, I will apply this patch in a few days.
I also plan to come up with a similar patch for scale_cuda.

will help grepping in the future if there needs to be a change to the

Oh, nevermind, i missed the v2.
