And because your hardware is not very powerful, you have bad performance. At least choose a codec that has hardware support and on your hardware, the only valid choice is H264 which is the only codec having hardware support for both encoding and decoding on your hardware.I don't know if it has any importance, but I am doing the encoding on a powerful AMD computer. The files are normally shared via NFS, but I have also tried copying them to the laptop.
You did not ask for it, I did not know you wanted it, sorry. Which of them do you want, all? I'll post the one for libx264 that you suggested. cer@Telcontar:/mnt/nfs/Isengard/xfsRaid/Videos/tmp> time ffmpeg -t 10:0 -i movie.mkv \
