Hello, since my Nokia N97 cannot play av1 codec videos I have to change the podcast to h264. I found this command on the net and tried it: mencoder -ovc x264 100124_sendung_neues_p.mp4 -x264encopts level_idc=12:bitrate=128:bframes=2:subq=7:partitions=all:8x8dct:me=hex:me_range=16:frameref=1:trellis=0:b_pyramid:weight_b:mixed_refs:threads=0:qcomp=0.6:keyint=250:min- keyint=25:direct=spatial -oac lavc -lavcopts acodec=libfaac:abitrate=56 -srate 48000 -af channels=2 -of lavf -ofps 25 -lavfopts format=mp4 -o 100124_sendung_neues_p-h264.mp4 But, it does not work, mencoder says "FATAL: Cannot initialize video driver" What is wrong with that command? I do not fully understand the h264 options, I just found this command on the net and it says these options are for average quality. I use version MPlayer dev-SVN-r30099-4.3-openSUSE Linux 11.1 (i686)-Packman Thanx Malte
