Thanks for the tip, Vouk , re not needing to use cuda-pixels to do standard GPU accelerated workflows. And for your assistance!

If this is the wrong place for this post, please let me know and I can move or re-create in the right place.

I'm trying to switch to VoukoderPro 1.2.3 from Voukoder Classic 13.4.1. I've successfully used NVIDIA NVENC HEVC hardware encoding with Classic (multiple versions) without issue for over a year now, to encode HDR videos.

I thought I had my scene designed correctly, but when I do a Performance Test, the test fails, and VoukoderPro crashes.

The end of logfile 01-voukoderpro-1.2.3-scene-test-video-nvidia-nvenc-hevc-cuda-upload-filter-encode-cuda-format-logfile.txt, attached, has these lines:

2024-05-27 00:01:38 (trace)	[FFmpeg:0] Changing video frame properties on the fly is not supported by all filters.
2024-05-27 00:01:38 (trace)	[FFmpeg:0] filter context - w: 3840 h: 2160 fmt: 0 csp: unknown range: unknown, incoming frame - w: 3840 h: 2160 fmt: 0 csp: bt2020nc range: tv pts_time: 0
2024-05-27 00:01:38 (trace)	[FFmpeg:0] Assertion ((src_linesize) >= 0 ? (src_linesize) : (-(src_linesize))) >= bytewidth failed at libavutil/imgutils.c:350

I tried 2 more iterations of the scene file to try to get it working.

Log file 03-voukoderpro-1.2.3-scene-test-video-nvidia-nvenc-hevc-encode-yuv420p-format-logfile.txt, attached, ends with the same 3 lines as above.

Log file 02-voukoderpro-1.2.3-scene-test-video-nvidia-nvenc-hevc-cuda-upload-filter-encode-yuv420p-format-logfile.txt, attached, ends differently:

2024-05-27 01:03:10 (trace)	[FFmpeg:0] auto-inserting filter 'auto_scale_0' between the filter 'Parsed_hwupload_cuda_1' and the filter 'Parsed_format_2'

I reviewed forum threads Unable to start VoukoderPro: FFmpeg error. and NVENC resolution scaling (scale_cuda) and wasn't able to find a way around the crash. I used scene2.zip Joe24 provided, from forum thread "Unable to start VoukoderPro ffmpeg error", as the base of my scene design.

What am I missing?

Attached are the 3 logfiles, the 3 scene files (in voukoderpro-1.2.3-scene-test-video-nvidia-nvenc-hevc-scenes.zip, attached), and 2 screen shots of Designer Performance Test settings used for all 3 scene tests.

The logs files and scene files have the same names, with different file extensions.

I'm using Windows 11 Pro and Nvidia 555.85 drivers.

Thanks for any help or insight!
