As usual, I can't appplicate the 4 patches:
0001-Add-lcms2-2.13.1-for-testing.patch
noclamp_in_histogram.diff
ffmpeg-6.1.patch10
opengl3_patch_very_small_speedup.patch
you put all additional source files in thirdparty/src ?
For first lcms2 patch i just "cd .." away from root of cin directory, "cat path_to_lcms2_patch/patch_itself | patch -p1"
if patch starts with cinelerra-5.1/ then apply it from directory above one with ./autogen.sh
if you want to compile with ffmpeg-6.1 and/or lcms2 you also need to re-run ./
autogen.sh/configure steps .
May be wait until Phyllis put out ffmpeg 6.1 and patches to git, so it will be less patching on your end?
Even making the changes manually, the build always fails. Could you
point me to the exact commands to apply them?
