Re: [FFmpeg-user] OVERLAY_CUDA and PGS Subtitle burn
Hi Community, Updated to the Cuda 11.1 (latest) and NVD drivers 455.23.04 (latest beta), FFmpeg Git and nv-codec-headers from today. Same result. no subtitles. So i will take a break on this option, maybe some bugs somewhere , which will have to wait until a dev has a look on this :) Is it something I can highlight on the Dev FFmpeg list, or the dev list is only reserved/exclusive for the dev ? So, i'm using now the traditional overlay filter, which give me the result i'm looking for: /ffmpeg -y -init_hw_device cuda=cuda -hwaccel cuda -i input.mkv -filter_complex "[0:v][0:s]overlay[vid];[vid]hwupload,scale_cuda=w=-1:h=720[vid]" -map "[vid]" -c:v h264_nvenc test.mkv i'm running around 400 fps (x16) on this command on my gear. Not sure if this is considered slow or fast, but for my own requirements it's nice already. Question related to this part only: -filter_complex "[0:v][0:s]overlay[vid];[vid]hwupload,scale_cuda=w=-1:h=720[vid]" : - based on this simple command, any tips/tricks to increase the FPS or it's considered already optimal.

Re: [FFmpeg-user] OVERLAY_CUDA and PGS Subtitle burn
Hi Dennis, thanks for the link. I have rebuild ffmpeg with all the latest version of any source i can find, update to the latest cuda 11 patch 3 and NV headers... Also included the latest vulkan sdk and support for ffmpeg. overlay_cuda and overlay_opencl, same issue: video appear but not subtitle. overlay_vulkan -> direct crash dump from ffmpeg. :( Any change from your side ?

Re: [FFmpeg-user] OVERLAY_CUDA and PGS Subtitle burn
Hi,
Changed the input format:
Video -> yuv420p
Sub -> yuv*a*420p (to include Alpha Channel)
Now the video is showing, but still no subtitles.
Still get the error message:

[FFmpeg-user] OVERLAY_CUDA and PGS Subtitle burn
Hi everyone,
i'm trying to use the OVERLAY_CUDA function to burn PGS titles over a video
and the result is not working.
i might misunderstand the usage of this function, so some help is welcome.
The result of this command is a black screen with audio, using 'standard'
overlay filter is working fine, but slow ...
Notice this message at the end of the log file (ffmpeg version
N-99194-g142ae27b1d ( compiled myself from git) ):
*Error while add the frame to buffer source(Internal bug, should not have
happened).*
Thanks for any help.

Re: [FFmpeg-user] overlay_cuda
Ok, thanks for answering.If any one read this email and want to create overlay_cuda filter then contact me please (kirpasaccess...@gmail.com), and I can pay for it!

As user only, I have no idea of the complexity of the task, and it depends on the rate of the freelance you hire. You first have to find some freelance (I know there exists platforms but never used one, neither know a name of one) who has the abilities to work on such project (which sounds not trivial, expect several days because of environment setup, build times and tests in addition to the implementation itself), and discuss with this person the price. Depending of the developer you manage to find and their abilities and experience, it might charge more or less and take more or less time. I am afraid I could not help more here, I do not have experience in this domain.

Re: [FFmpeg-user] overlay_cuda
Hi! Thanks for answering. How much, do you think it will be cost to develop overlay_cuda filter if we already have scale_npp, etc (cuda) filter for quick start? 8 ноября 2019, 16:41:35, от "JackDesBwa" < jackdes...@desbwa.org >: 2019-11-07 22:39, Paul B Mahol : > No. > Nice top-posted answer, clear, concise, but totally empty of meaning. :-/ Do you realize that in mailing-list you are interacting with humans ? Such answer, as well as the one you gave recently for the color specification bug (that I was sarcastic about in my answer), are perhaps acceptable for dictators and assholes, but certainly not in sane social interactions with human beings. A concise rational is the absolute minimum IMHO. By the way Alex, ffmpeg developers are volunteers human beings, not slaves that develop what you might need. It is a tremendous money-equivalent job you asked to do for free (well, actually whatever the feature, most people find it very pricey when they discover the true price it costs). However, I am almost sure that if you develop such filter (or pay a freelance to do so) and propose it to the community, it will be reviewed and integrated in the software if well designed.

[FFmpeg-user] overlay_cuda
We have overlay, overlay_qsv, overlay_opencl filters but don't have overlay_cuda for speed up transcoding videos on nvidia GPU only. Using sw overlay filter is slow down the transcoding because frames copied between CPU and GPU ram. Can You implement overlay_cuda filter, please?
