  checkasm: Fix defining CHECKASM_HAVE_GENERATED_H Commit 4569ab7eaa0d709fa9b578bc86d703212638a16c tried to set this only on the object files for the checkasm library itself, but missed that EXT_CHECKASMOBJS lacks the path prefix, thus this wasn't set at all. Alternatively, for simplicity, we could keep passing this for all checkasm object files, not only the checkasm library objects; the other object files don't use it in any case.

  configure: filter out -D options from msvc link The linker does not understand or require -D (define) options, and unknown options are treated as errors. Fixes building with MSVC and SChannel, which regressed after 1e031d4af713168259ea3fd82c54a25f30b7bada

  avcodec/decode: Move exif declarations to exif_internal.h It is (arguably) a slightly better place for them and avoids a forward declaration of enum AVExifHeaderMode which is not possible in ISO C before C23 (and requires specifying the underlying type with C23).

  swscale/tests/swscale: add -scaler/-scaler_sub parameters to set scaler algorithm The -unscaled parameter has been removed in favour of "-scaler none". Some legacy scalers cannot be selected with these options (i.e.: SWS_X and SWS_FAST_BILINEAR). To test these, the -flags parameter shoule be used instead. This option sets the scaler/scaler_sub fields in SwsContext. There is a comment about these fields in struct SwsContext: Note: Does not affect the legacy (stateful) API. This comment is not entirely correct, since scaler/scaler_sub are taken into consideration to select the algorithm, but that doesn't update the flags field, which is still used to select implementations: libswscale/x86/swscale.c:574: if (c->opts.flags & SWS_FAST_BILINEAR && c->canMMXEXTBeUsed) { libswscale/ppc/swscale_vsx.c:2033: if (c->opts.flags & SWS_FAST_BILINEAR && c->opts.dst_w >= c->opts.src_w && c->chrDstW >= c->chrSrcW) { libswscale/swscale_unscaled.c:2465: && (!needsDither || (c->opts.flags&(SWS_FAST_BILINEAR|SWS_POINT)))) libswscale/swscale_unscaled.c:2650: if (c->opts.flags&(SWS_FAST_BILINEAR|SWS_POINT)) { libswscale/utils.c:1279: && !(sws->flags & SWS_FAST_BILINEAR) libswscale/utils.c:1388: (flags & SWS_FAST_BILINEAR))) libswscale/utils.c:1417: && (flags & SWS_FAST_BILINEAR)) { libswscale/utils.c:1437: if (flags & SWS_FAST_BILINEAR) { libswscale/utils.c:1648: if (c->canMMXEXTBeUsed && (flags & SWS_FAST_BILINEAR)) { libswscale/swscale.c:678: if (c->opts.flags & SWS_FAST_BILINEAR) { Sponsored-by: Sovereign Tech Fund Signed-off-by: Ramiro Polla <[email protected]>

  avformat/tls_{gnutls,mbedtls,openssl}: Add config_components.h Forgotten in fb5dd6ec60f42cd19ce5e59d745e72fdb73731f8, effectively disabling the #if CONFIG_UDP_PROTOCOL block; it triggered a -Wundef warning as well as an unused-variable warning in tls_openssl.c. Also use the TLSShared* in tls_openssl to avoid an unused variable warning if the UDP protocol is disabled. Signed-off-by: Andreas Rheinhardt <[email protected]>

  swscale/tests/swscale: add -api parameter (supersedes -legacy parameter) The "-legacy 1" option was added in 101a2f6fc60 to run the main conversion with the legacy scaler. This was done by forcing the use of the legacy API. This way, it was possible to pass "-flags unstable" and still ensure the legacy scaler path was being taken. New legacy-related parameters will be added to the test tool, so it makes sense to rename the -legacy option to reflect what it was actually doing.

  avcodec/utils: Don't attempt to derive CodecID name from de/encoders The list of codec descriptors is supposed to encompass all codec IDs; it certainly encompasses all codec IDs used by de/encoders (this is checked in the avcodec test program which is run via FATE). So the avcodec_find_decoder()/avcodec_find_encoder() are pointless. Signed-off-by: Andreas Rheinhardt <[email protected]>
