The nvidia drivers for linux have always been very powerful.

It was just the updating process and the lack of need why I swapped to nouveau.

If @chapolin says nvenc works very well I would switch from nouveau to nvidia proprietary.

edit: I changed to proprietary nvidia-driver at the mobile workstation with Quadro P4000.

Also I see that histogram and probably other plugins are slowing down playback dramatically. Maybe GPU acceleration would improve playback performance too.

edit: histogram doesn't seem to profit of GPU acceleration.

I have AMD graphics and so I cannot advise you directly.
I don't think noveau supports cuda/nvenc/nvdec. However having a Quadro card with noveau means sacrificing it; unfortunately the graphics/video world does not have good support in the Open.

Though I prefer my CPU Xeon 14c/28t rendering at desktop (and the quality) I would like to have a quicker solution for my mobile workstation 4c/8t with Quadro P4000 to do some quick previews.

Can you say whether it plays out for you?

I don't like to install proprietary nvidia drivers but I would if you say nvenc plays out well for you.

With nouveau drivers I don't need to care of anything. With the nvidia drivers there probably is more to take care of.

Yes, using the ...-nvenc preset will use the GPU, unless there are problems.

If that doesn't seem to work, try running CinGG from a terminal and report the messages on the hardware.

@andreapaz So if I understand correctly, in this case, during rendering, if we use "nvenc" it will still be the graphics card that will be used?

But as I wanted to test on a small selection because my project is really big, in the timeline I made a small selection of one minute and in the render box, in the “render range” parameter I indicated “selection”. As a result, I got render files that don't really correspond to my selection, which is a bit weird.

So glad you reported this bug which has been in the code since 2019. Fortunately, Andrew-R has found a fix for it and it will be in next month's release. So now it will start/stop according to your In/Out points or a selection. The whole project and single frame work as they have been.

Notice, however. The message is only about decoding, that is, playback on the timeline. Cuda/Vdpau settings (and vaapi) are also about decoding. For rendering you can only use the various rendering presets and if you want to customize them or create new ones.

Thanks for the clarification.

"HW device init failed, using SW decode" just means that instead of using your graphics board to handle the video, it will just use the software the same as it would have if not setting the hardware capability.

set to “jpeg” try putting it to “mpeg”

I've tried several combinations but the alerts are still there. So I use cuda which doesn't cause any alerts.

HW device init failed, using SW decode.

About this message, what happens next? rendering uses h264 (I imagine with settings similar to those initially selected for h265-nvenc?) for problematic files like png? and h265-nvenc at the same time for files that work?
