Hello How to solve this ?

[adamjw24]

Could you please paste a full log of what it is you're doing?

Do you open a project through "Open CMake dir" or generate it with make configure or cmake ... or the CMakeGUI?

Looks like a broken MSVC installation, but cannot be sure without more info.

I installed CMake on Visual Studio 2019 Community and Cloned the Git Repository Im using the Paper to install the vvdec step by step when i open the folder with the project i even cant debug like vvenc I get the following error in the error list

The problem is, your build fails before it actually starts processing VVdeC, it fails at checking your environment, which makes it hard for me to understand.

Can you download some sample C++ project (I'm sure MSVC or CMake have stuff like that) and see if you can build it?

Otherwise, I see you checked out the project to OneDrive, which as I understand is cloud storage, right? Maybe try cloning properly to local hard-disk?

Last but not least, please use the latest version of VVdeC.

[asqarkababi]

I build vvenc before just fine without any problems with the last builing i will try vvdec again this time with cloning it again there persist the same problem it seems that ome files are missing or something that were present in the vvenc repositor

[adamjw24]

Strange. I'll ask around if someone has seen this problem. What if you do it from the console?

# git clone ...
# cd vvdec
# make distclean
# make install-release

[asqarkababi]

make functions dont work on the VS Console because of the Cmake proble

If you want to use make/Makefiles on Windows be sure to install gnuwin32. Please have a look into the wiki to see how you can build via make or via cmake: https://github.com/fraunhoferhhi/vvdec/wiki/Build

You can also build with cmake by using e.g.: cmake -S . -B build/static -A x64 -DCMAKE_CONFIGURATION_TYPES=Release cmake --build build/static --config Release -- /maxcpucount:8 /verbosity:minimal /nr:false

Thank you very much i installed mingw32 and in the commandline in VSS2019 i wrote instead of make mingw32-make install-release and it worked i decoded a video to yuv and watched the video on yuvplayer but it looks like this and its very small

[adamjw24]

About how the video looks, did you have a look at? https://github.com/fraunhoferhhi/vvdec/discussions/50

[asqarkababi]

Could you give me a hint how to decode it properly i encoded it with the simple app and not with the professional app is there a difference between their results ? is it possible to decode the encoded file with the simple app with vdecapp ?

[adamjw24]

You probably decoded it properly, you just need to view it properly now. Your format is yuv420p10le, and not yuv420p.

Could you do a list of the steps you did (exact command lines) as well as list the files and files sizes of all used files (input, bitstream, reconstruction)?

[asqarkababi]

For the vveec i made this command i found on the internet the file is 720p but i dont know if its really now converted to 1080p

And the filesizes are as follows

I hope i understood your question correct and sent you the correct files

[adamjw24]

This will not work. You cannot feed an mp4-file to VVenC. You could for example use the following script to transcode an mp4-file to .266: https://github.com/fraunhoferhhi/vvenc/discussions/116

Alternatively, decode the mp4 to a YUV using: ffmpeg -i R.mp4 -f rawvideo -pix_fmt yuv420p10le R.yuv

Than, repeat the process using -i R.yuv instead of -i R.mp4 in the VVenC command-line.

[asqarkababi]

Thank you very much i will try it out and report you the outcome One question should i use this coomand in the vvenc : vvencapp -i R.yuv -s 1920x1080 -c yuv420 -r 30 --preset medium --qp 31 --qpa 0 -ip 64 -t 4 -o R.266 ?

[adamjw24]

Wait, no. If you convert mp4 to yuv as yuv420p10le, you have to use -c yuv420_10. So: vvencapp -i R.yuv -s 1920x1080 -c yuv420_10 -r 30 --preset medium --qp 31 --qpa 0 -ip 64 -t 4 -o R.266

[asqarkababi]

I converted the mp4 file to yuv file but vlc player doesnt play it even in the documentation of VLC it ia compatible with it

[adamjw24]

And ffplay? ffplay -f rawvideo -pix_fmt yuv420p10le -i R.yuv

I'm not an expert on VLC so don't know how to make it play.

[adamjw24]

Why don't you just use YUView or other yuvplayer to play the yuv?

[asqarkababi]

And ffplay? ffplay -f rawvideo -pix_fmt yuv420p10le -i R.yuv

I'm not an expert on VLC so don't know how to make it play.

I will try the command

Why don't you just use YUView or other yuvplayer to play the yuv?

I used yuvplayer and i got that pixelated output i will try YUVIEW too to see how the result is

[adamjw24]

Change the input format of your yuvplayer from 8 to 10 bit

[adamjw24]

Or maybe actually more simply, use an 8-bit pipeline: Convert R.mp4 to R.yuv: ffmpeg -i R.mp4 -f rawvideo -pix_fmt yuv420p R.yuv Encode with VVenC, 8-bit: vvencapp -i R.yuv -s 1920x1080 -c yuv420 -r 30 --preset medium --qp 31 --qpa 0 -ip 64 -t 4 --internal-bitdepth 8 -o R.266 Decode with VVdeC: vvdecapp -b R.266 -o R2.yuv

Now both R.yuv and R2.yuv are 8-bit YUVs. I think this would be more suited for your testing.

Thank you very much i will try it out and will see if its working

[asqarkababi]

I tried it out video is not playing no pixelation anymore

[adamjw24]

With the 8-bit pipeline you should be able to just use yuvplayer.

[asqarkababi]

With the 8-bit pipeline you should be able to just use yuvplayer.

Strange its still pixelated

[adamjw24]

I don't know than. For YUView you have to set the correct size in the right pane. I don't know what yuvplayer is. Did you set the correct video size? yuv is a format that does not contain any metadata whatsoever (no width/height, nothing), so you have to tell your player explicitly how to interpret this.

Please make sure you can actually view your raw YUV input properly before we continue discussing usage of VVenC and VVdeC.

[asqarkababi]

So i changed the video size to the Original of the Video i had and its working and im sorry as im still a beginner My Question is : is not the video after we used ffmpeg and changed the resolution is not the display resolution changing to the desired resolution that is 1080p ?

[adamjw24]

Your source it what it is. Just set the proper resolution while encoding (-s 540x360).

[asqarkababi]

Thank you very much i will add the proper resolution in vvenc the next time i will encode

[asqarkababi]

it seems both encoder and decoder work properly I thank you so much for your help I close this issue now
