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.
My test with own build Cingg to use my system ffmpeg 7.1, shows that
hdv.m2t and hd.mov rendering with high (or 1) profile to av1_vaapi.webm
works on Arc A750, when tweeking the av1_vaapi profile as follows:
change "profile" to "vprofile" and rc_mode from "QVBR" to "CQB" (both
according to ffmpeg output)
(just profile=main also works, possibly due to main is default?)
-------------
# Nvidia 4000+ series (better nvenc/vdpau)
# AMD Radeon 7000+ series
# Intel Xe2, Arc+ series
cin_hw_dev=vaapi
g=30
vprofile=high #(main, professional)
rc_mode=CQP
Then this seems to fit with

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
<http://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
