* avcodec/ffv1: Move ffv1_template.c inclusion to dec/enc templatesAndreas Rheinhardt2022-10-20
| | | | | | | | | | | | | | | | | | | Both the FFV1 decoder and encoder use a template of their own to generate code multiple times. They also use a common template, used by both decoder and encoder templates which is currently instantiated in ffv1.h (and therefore also in ffv1.c, which doesn't need it at all). All these templates have the prerequisite that two macros are defined, namely RENAME() and TYPE. The codec-specific templates call the functions generated via the common template via the RENAME() macro and therefore the macros used for the common template must coincide with the macros used for the codec-specific templates. But then it is better to not instantiate the common template in ffv1.h, but in the codec specific templates. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
