> > Maybe someone can explain how to use in filters?
This seems to be a gap in documentation, because it comes up every now and then on the mailing list. I'll try to be brief. When using "-hwaccel cuvid" the hw-decoded frames stay in GPU memory and are passed onto the hw-encoder. The filters that you are trying to use are software filters. They require decoded frames to be in CPU memory (and a format that is compatible). To remedy this, you have two choices: remove "-hwaccel cuvid" from your commandline (removing it causes decoded frames to be copied from GPU->CPU memory and then CPU->GPU for encoding) OR add 'hwdownload,format=nv12' to the beginning of filter.txt and 'hwupload_cuda' to the end. The first option definitely reduces performance. I have not specifically benchmarked the second, but it likely has the similar performance. The filters you are applying will likely cause more reduction than either though so it's moot. Hope that helps. -James _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
