Set shebang to bash (default sh on debian is dash) and uses simpler call to shell script in makefile Please test!

Debian 13 and bld_prepare.sh
by Andrew Randrianasulu 08 Dec '25

08 Dec '25

Installed Debian 13.2.0 amd64 on qemu. Now trying to see bugs reported by users our script blds/bld_prepare.sh might need some additions debian-13 is vasically same as debian just wothout 2to3 package (it was python thing). I am not sure how to best handle this: make new case for debian-13 or just delete 2to3 from debian section (I think our python script in guicast was python3 ready for some years)?

nvenc settings ?

I wonder if this OBS forum thread can help you? https://obsproject.com/forum/threads/true-constant-quality-mode-for-h264_nv… ==== rc=constqp and cq=2 ==== While how it work under the hood is question worth many threads .... our profile is veeeery basic, but it worked for me on GT710, so I suggest to put more advanced settings into another, new profile... mp4 h264_nvenc # encode for nvidia graphics hw only preset medium profile main

errors encountered when building using thirdparty/ libraries
by Rob Prowel 07 Dec '25

07 Dec '25

FYI: gcc-14 sees the bitshift of a negative value as an error. SimpleModule.h:126:47: error: left operand of shift expression ‘(-1 << 31)’ is negative [-fpermissive] 126 | static const int kMinSignedValue = -1 << kScaleBits; | ~~~^~~~~~~~~~~~~ make[6]: *** [Makefile:361: ALAC.lo] Error 1 make[6]: Leaving directory '/6TB/storage/programming/cingg/cinelerra-5.1/thirdparty/audiofile-0.3.6/libaudiofile/modules' make[5]: *** [Makefile:657: all-recursive] Error 1 make[5]: Leaving directory '/6TB/storage/programming/cingg/cinelerra-5.1/thirdparty/audiofile-0.3.6/libaudiofile' This appears to have been fixed in upstream github master, although there was some differing of opinion between maintainer and patch submitter about the specific bit manipulation operations to fix it. build using (cingg internal libs) ./configure \ --prefix=/sharebin/cingg2511 \ --with-thirdparty \ --with-nv \ --with-gl \ --with-xv \ --with-alsa \ --without-cuda \ --enable-audiofile \ --with-jobs=1 \ now succeeds, but cingg version of ffmpeg/libavcodecs does not seem to implement nvenc correctly. ie there is little difference in encoding times between h264 and nvenc when using identical target bitrates. However, when using my Debian supplied or custom compiled ffmpeg command line transcode there is a 3:1 to 5:1 performance rate increase in nvenc. I think nvenc needs to be FAST so it can serve as the a default intermediate high-bitrate render format in projects. -Rob

Patch for audiofile-0.3.6 in cinelerra-gg
by Andrew Randrianasulu 07 Dec '25

07 Dec '25

It builds locally on gcc 11.2.0 i586 ... Reason why it was unnoticed probably because audiofile build disabled by default and probably only needed for in-tree esound build ...

duplicate code in cinelerra that also exists in support libraries
by Rob Prowel 06 Dec '25

06 Dec '25

Please help me to understand why. This is my make-config and I'm building from scratch on Debian-13(trixie). I've re-run autoconf and aclocal to support the newer macros/features. Also note that I'm leveraging the distro libraries over the in-source thirdparty ones. I have sucessfully built this way several years ago. ----------------------------------------------- #! /bin/bash CUDA_PATH=/usr \ ./configure \ --prefix=/sharebin/cingg2511 \ --with-cuda \ --with-nv \ --with-gl \ --with-xv \ --with-jobs=8 \ --with-alsa \ --enable-audiofile \ --with-thirdparty=no ----------------------------------------------- build fails due to function redeclaration of int GifQuantizeBuffer(unsigned int Width, unsigned int Height, int *ColorMapSize, GifByteType * RedInput, GifByteType * GreenInput, GifByteType * BlueInput, GifByteType * OutputBuffer, GifColorType * OutputColorMap); in filegif.h and filegif.C...but this method also exists in the thirdparty library giflib. The reason it fails is that in the library the pointers are const (as they should be) but in the duplicated code under cinelerra directory they are not...and simply adding const in the included code is not a fix, IMHO. Lets please evaluate why the library code was duplicated within the project source in the first place. giflib is not only available under the thirdparty directory, but is a common library on most linux distros. It seems odd that it's both referenced from the library AND duplicated in-source. So far the only dependency I've had to use from the thirdparty directory is libdpx since it is quite obscure and not a standard part of Debian. -Rob

Based on Georgy's email ( https://www.mail-archive.com/[email protected]/msg09216.html) and his further explanations, I would like to propose an addition to the manual regarding an important aspect of CinGG's operation. I am attaching a document and an image. If you can improve, correct, and add information, we can then consider modifying the manual.[image: AV_sync.png]

I think? At least when using ffmpeg from git ...

Vulkan prores decoding in ffmpeg.git
