The following FFmpeg hardware-acceleration script works fine. But when I try to apply a fade in and out to the overlayed image it breaks. Is there a solution?
Working: ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i vidTest.mp4 -hwaccel cuda -hwaccel_output_format cuda -i imgTest.png -filter_complex “[0:v]scale_npp=960:540:format=yuv420p,hwdownload,hwupload_cuda,scale_npp=format=nv12[base];[1:v]scale_npp=470:-1:format=nv12[A];[base][A]overlay_cuda=515:80” -c:a copy -c:v h264_nvenc -y outTest.mp4
Breaks: ffmpeg -hwaccel cuda -hwaccel_output_format cuda -i vidTest.mp4 -hwaccel cuda -hwaccel_output_format cuda -i imgTest.png -filter_complex “[0:v]scale_npp=960:540:format=yuv420p,hwdownload,hwupload_cuda,scale_npp=format=nv12[base];[1:v]scale_npp=470:-1,fade=st=0:d=2:alpha=1,fade=out:st=9:d=2:alpha=1,trim=0:15,setpts=PTS+4/TB,format=nv12[A];[base][A]overlay_cuda=515:80:enable=‘between(t,4,15)’” -c:a copy -c:v h264_nvenc -y outTest.mp4
Error: [Parsed_overlay_cuda_10 @ 0x355b340] Timeline (‘enable’ option) not supported with filter ‘overlay_cuda’ [AVFilterGraph @ 0x2ebc880] Error initializing filter ‘overlay_cuda’ with args ‘515:80:enable=between(t,4,15)’ Error initializing complex filters. Not yet implemented in FFmpeg, patches welcome
Thank you in advance for any guidance you may have.
