Now applying the patches has worked. I simply had a double patch with two different numbers in the title. Once I removed one of them, it worked without any problems. Now, however, I'm having problems with ./configure; I get this result:
./configure --prefix=/usr --with-single-user --with-config-dir=/home/paz/.bcast6 --enable-libsvtav1 --with-vulkan [...] configure: error: Please install autoconf-archive package and re-run autoreconf
After installing autoconf-archive, ./configure worked normally. What is autoconf-archive used for?
For fancy macro to check if compiler can shut up -Woverloaded-virtual (some compilers just stop if you give them wrong disable switch) Local thing on my Termux due to clang there and fact it was NOT working right last time Phyllis tried it on her machine with Fedora ...
The “YUVA-16 Bit” color model applies without errors and playback works, but none of the native filters in the “Color Correction” section work. The error message is:
VFrame::to_texture: unsupported color model 16.
Ah, was it with X11-OpenGL? I only tested lightly on X11 without "Use direct" checked ... Thanks anyway, more pieces to enable even for testing ...
(Note: Using the compositor's videoscope works fine; using the videoscope filter on the timeline does not work.)
Regarding rendering presets with Vulkan:
When I use your preset (ffv1_vulkan.mov, with pix_fmt=nv12), I get this error:
cant find codec ffv1_vulkan:/home/paz/test_vulkan.mov Render::render_single: Session finished.
You probably should compile with enabled libplacebo, too? It will drag in shaderc compiler, used for ffv1 encoder.
If I use one of my presets (e.g., hevc_vulkan.mov). I get:
Specified pixel format nv12 is not supported by the hevc_vulkan encoder.
Even if I change the value nv12 --> vulkan, rendering fails with the same error I've always had and can't resolve:
A hardware frames reference is required to associate the encoding device.
I think you still can try just set cin_pix_fmt to nv12, form preset and not from GUI (there is some problem with Vulkan specificailly so encoder must be opened early, earlier than all other hw encoders so far)
I have never been able to understand my problems with Vulkan, which are beyond my capabilities, so there is no point in continuing to try. Sorry.
Well, this is still new, cutting edge technology.Do not feel completely discouraged. But do not push yourself too hard in testing that ...
