My NVIDIA and FFMPEG configuration is as follows: Linux TestBox1 6.8.0-41-generic #41-Ubuntu SMP PREEMPT_DYNAMIC Fri Aug 2 20:41:06 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

My efforts usually work in terms of the scale but not the crop, here is an example of the type of problems I have been having: The source file in this example is a short mpeg2 video (960x540 with black bars top and bottom). The command is currently run from a bash script. ffmpeg -y -hwaccel cuda -hwaccel_output_format cuda -c:v mpeg2_cuvid - crop 960x408x0x66 -i $1 -vf scale_npp=1280x544 -c:a copy -c:v h264_nvenc -b:v 2M -preset slow $2 This is throwing the following error: [mpeg2_cuvid @ 0x5e6d9deb56c0] cuvid decode callback error [vist#0:0/mpeg2video @ 0x5e6d9de85b40] [dec:mpeg2_cuvid @ 0x5e6d9de7b7c0] Decoding error: Generic error in an external library I have looked around the web but none of the solutions offered have worked for me. Do I have a problem with my ffmpeg build, should the list of filters include something like crop_cuda or crop_npp or have I just got the wrong syntax to perform everything on the GPU (is it even possible). Thanks for any suggestions. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
