But as nvenc can take yuv420p input, this is not necessary in most cases. This should perform the exact same operations as adding the de/interleaving functionality to the transpose_npp filter itself, and thus not perform worse in any way. smime.p7s Description: S/MIME Cryptographic Signature ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
