You're looking a little skinny in that photo

Thank you! You are very kind.

Life smacked me hard last night. Still reeling. I did watch some GTC speeches. Quite amazing progress. Oh, and I downloaded the Video SDK. Swept up the litter and now off to the nest.

Latest Video SDK and CUDA 11:

Again, ran into lots of dependencies and non-obvious environment variable settings. Definitely not for your average moose!

Next, I will try to bring up DG's stripped down decoder that served as the basis for all the CUVID work. That will prove that everything is in place to bring up DGSource(). We'll also need to install Avisynth+ and Vapoursynth. But first, it's backup time.

It's encouraging that things have gone so well.

Nice.
Installing VS is easy thing actually, as well as Avisynth+ on Linux. VS uses generic "./configure && make" solution while Avs+ is a CMake project.

Would it be possible to join up all the great hints, like installing AVS+ and VPY, for future reference

Assuming that was directed at DJ. If so, I second that motion.

If it was directed at moi, I'll post instructions after I figure it out.

Vapoursynth

Code: Select all

git clone https://github.com/vapoursynth/vapoursynth.git
cd ./vapoursynth
git clone https://github.com/sekrit-twc/zimg.git --branch v3.0
./autogen.sh
(if you want to build ffms2 plugin, make sure ffmpeg stuff is installed before next step)
pip3 install -r python-requirements.txt
./configure --enable-pic
make -j$(nproc)
sudo make install

Avisynth

Code: Select all

git clone https://github.com/AviSynth/AviSynthPlus.git
cd ./AviSynthPlus
mkdir build && cd build
cmake ..  
make -j$(nproc)
sudo make install

Actually meant for Rocky, but thank you DJATOM

Boy, would the Linux sub-forum be handy about now

Posted: **Fri May 21, 2021 8:23 pm**

Yes, indeed, thank you DJ!

Sherman is missing in action. I'll send a PM to Mr Peabody. He keeps Sherman on a pretty short leash.

pretty short leash

cute joke

Posted: **Sat May 22, 2021 10:58 am**

You never miss a trick.

Successfully built and ran the minimal decoder with NALU feeding:

don@debian:~/cuVideoDecode$ g++ -static-libstdc++ -static-libgcc -O3 -o decode cuh264dec.cpp nalu.cpp /usr/lib/x86_64-linux-gnu/libnvcuvid.so /usr/lib/x86_64-linux-gnu/libcuda.so
don@debian:~/cuVideoDecode$ ./decode Alba.264 Alba.yuv
GPU in use: NVIDIA GeForce RTX 2080 Ti
Processed 580 frames
don@debian:~/cuVideoDecode$ ls -l Alba.yuv
-rw-r--r-- 1 don don 1817395200 May 22 12:10 Alba.yuv
don@debian:~/cuVideoDecode$

:belly-laugh:

Next step: Install and test Avisynth+ and Vapoursynth.
Next-next step: Port DGSource().
Next-next-next step: Create linux native CLI indexer (to avoid DGIndexNV under wine).
Next-next-next-next step: Port the other filters in DGDecodeNV.dll.

A Linux subforum is currently being created. Material in this thread will be moved and split by tool. Closing this thread.

Posted: **Sat May 22, 2021 1:28 pm**

Sherman and I have split the original linux thread into two in the new Linux subforum. The split may not be perfect but it should be good enough moving forward. Please use the appropriate thread based on the respective tool.

Sherman is on a probation period for moderator status. He will be supervised during this period and if all is well he will be promoted to moderator.
