[FFmpeg-user] 4K 60Hz Directshow Video Capture

Windows 10 Intel i7-8700K GTX 1050Ti 16GB DDR4 SATA Samsung Evo I'm using a Yuan 4K60 capture card with the end goal of capturing the video in a lossless format. I need it to be lossless as the clips will be used to test hardware h264 encoders. Product page:

Re: [FFmpeg-user] 4K 60Hz Directshow Video Capture

I've tried all manner of encoders but get the same buffer error. I've actually gotten a 64-bit fork of VirtualDub to work and capture everything but it occasionally drops frames and I like the CLI of ffmpeg. I guess I could use the VD CLI. Can anyone advise? I could use Linux but I'd rather

Hi James, ffmpeg -f dshow -video_size 3840x2160 -framerate 6/1001 -rtbufsize 21 -pixel_format bgr24 -i video="MZ0380 PCI, Analog 01 Capture" -c:v h264_nvenc -preset lossless -f null - Gives me the same error ffmpeg -f dshow -video_size 3840x2160 -framerate 6/1001 -rtbufsize

Re: [FFmpeg-user] 4K 60Hz Directshow Video Capture

Hi Alex, I looked at your attached log. It appears to me that using libx265, your computer cannot encode fast enough. It appears your computer is encoding about 10.5 fps, but your input is about 60fps. So a lot of frames get buffered every second while they're waiting to be encoded. This leads to

Re: [FFmpeg-user] 4K 60Hz Directshow Video Capture

Hi James, I get the same issue with this command: ffmpeg -f dshow -video_size 3840x2160 -framerate 6/1001 -rtbufsize 21 -pixel_format bgr24 -i video="MZ0380 PCI, Analog 01 Capture" -c:v h264_nvenc -preset lossless -f null - Is there a way to accelerate the decoding of rawvideo?

[FFmpeg-user] FFmpeg hanging on complex filter

Hello all, Recently I upgraded my FFMPEG version to the latest release. In doing so, a command I previously used does not work anymore. Here is the command ffmpeg.exe -y -i -filter_complex "[0:v]trim=start_frame=0:end_frame=100,setpts=PTS-STARTPTS[a0];
