how do you get this working on windows?!

[doubledrat]

sorry to have to ask, but I've just spent 2 hours trying to get vulkan to work on windows and just keep getting this when I use your code -

python DoVi2.py -i E:\downloads\dolby-vision-people.mp4 -o dvpeople.mp4 --bitrate 8000 --type hdr10 ['ffmpeg.exe', '-nostdin', '-loglevel', 'error', '-stats', '-y', '-init_hw_device', 'vulkan=vk:0', '-filter_hw_device', 'vulkan', '-i', 'E:\\downloads\\dolby-vision-people.mp4', '-vf', 'hwupload,libplacebo=peak_detect=false:colorspace=9:color_primaries=9:color_trc=16:range=tv:format=yuv420p10le,hwdownload,format=yuv420p10le', '-c:v', 'libx265', '-map_chapters', '-1', '-an', '-sn', '-b:v', '8000k', '-x265-params', 'repeat-headers=1:sar=1:hrd=1:aud=1:open-gop=0:hdr10=1:sao=0:rect=0:cutree=0:deblock=-3-3:strong-intra-smoothing=0:chromaloc=2:aq-mode=1:vbv-maxrate=160000:vbv-bufsize=160000:max-luma=1023:max-cll=0,0:master-display=G(8500,39850)B(6550,23000)R(35400,15650)WP(15635,16450)L(10000000,1)WP(15635,16450)L(1000000,100%):preset=slow', 'dvpeople.mp4_hdr10_slow.mp4'] Device creation failed: -12. Failed to set value 'vulkan=vk:0' for option 'init_hw_device': Cannot allocate memory Invalid filter device vulkan.

Error opening output files: Filter not found

I know it's not a problem with your code, but I'm hoping you can point me to a solution.

I have vulkan installed and vulkancube works, but I have no idea how to install the libplacebo filter and all the distributions I can find are just for un*x. I also don't know how to tell ffmpeg that I have vulkan. the only instructions I can find say go to the display part of the config program, which doesn't exist.

thanks in advance

@frankivsk1 you can send me a message to discord if you like( discord user: wks_uwu ) , in the message you send indicate that you are the github user because I don't usually reply to messages.

@doubledrat the issue is simple to answer, you do not have vulkan installed and/or you do not meet some of the requirements.

I had some trouble getting it to work and blamed the ffmpeg.exe in my PATH

I got

Unrecognized option 'x265-params'.
Error splitting the argument list: Option not found

I downloaded https://github.com/BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-master-latest-win64-gpl.zip and extracted it in "C:\Program Files" Then I put it in my System's path (right-click this computer -> advanced -> environment variables -> Path)

then did ffmpeg -hwaccels and it gave me this:

ffmpeg -hwaccels
