Keep handle_side_data available in all cases as this way X264_init does not require additional version based conditions within it. Finally, add a FATE test which verifies that pass-through of the MDCV/CLL side data is working during encoding. --- configure | 2 + libavcodec/libx264.c | 80 ++++++++++++++++++++++++++++++++++++ tests/fate/enc_external.mak | 5 +++ tests/ref/fate/libx264-hdr10 | 15 +++++++ 4 files changed, 102 insertions(+) create mode 100644 tests/ref/fate/libx264-hdr10 diff --git a/configure b/configure index 2b4c4ec9a2..44be4ef819 100755 --- a/configure +++ b/configure @@ -2531,6 +2531,7 @@ CONFIG_EXTRA=" jpegtables lgplv3 libx262 + libx264_hdr10 llauddsp llviddsp llvidencdsp @@ -6925,6 +6926,7 @@ enabled libx264 && require_pkg_config libx264 x264 "stdint.h x264.h" x require_cpp_condition libx264 x264.h "X264_BUILD >= 122" && { [ "$toolchain" != "msvc" ] || require_cpp_condition libx264 x264.h "X264_BUILD >= 158";
