We tried to update cinelerra-gg to ffmpeg 7.1 and ran into two problems: First, vf_scale now declares dynamic input and was filtered out by code in cinelerra/pluginfclient.C
int flag_mask = AVFILTER_FLAG_DYNAMIC_INPUTS | AVFILTER_FLAG_DYNAMIC_OUTPUTS; if( filter->flags & flag_mask ) return AVERROR(EPERM); ok, it was easy to workaround just by commenting this line out But then it turned out our vaapi/qsv profiles stopped working, anytime there was "profile=high" line. Oh, dang. Looked around and found this thread on Narkive https://ffmpeg-user.ffmpeg.narkive.com/FRd15m7B/ffmpeg-1-0-null-0xcb4700-eval-0x7fff0d95cf00-undefined-constant-or-missing-in-wpred replaced "profile" with "vprofile", now it appear to work again. But this was a bit unexpected, I do not think both changes were mentioned as breaking in release notes? It sort of sad to see this "hidden" breakage every release. Ffmpeg is not only library that does so, and tracking them all is not fun anymore. If you can't avoid making breakage - put it up front in release notes, not hide it like in bad commercial advertisement. our source: git://git.cinelerra-gg.org/goodguy/cinelerra.git you can build ffmpeg 7.1 into /usr/local and then ./auto gen.sh + configure --without-thirdparty --with-single-user --without-libdpx + make + make install. if it does not work on your system - look around in blds directory for various scripts adding --disable-component switches to configure. binaries and profiles will be in $cin_src_root/bin _______________________________________________ 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".
