Hi resent got a new audio unit for the car that also plays video's. I have some music videos that i want to recode for the unit, I would to like to resize and change the sound down to mp3.
Now I have had a been doing a bit of encoding but with no real confidence or 100% knowledge of the tools and the terminology. I recently used mencoder to reencode a vob file from the local ultra sound (having a new baby soon) and I thought I had encoded to dixX INPF=$1 mencoder "$INPF" -sws 2 -oac mp3lame -lameopts vbr=3 -ovc lavc -lavcopts vcodec=mpeg4:v4mv:mbd=2:trell:vpass=1 -ofps 25 -o /dev/null mencoder "$INPF" -sws 2 -oac mp3lame -lameopts vbr=3 -ovc lavc -lavcopts vcodec=mpeg4:v4mv:mbd=2:trell:vpass=2 -ofps 25 -o "$INPF.avi" but when I tried to view it with divx codec on windows it barfed, I need some other drivers. So I thought come to the experts first and try and get it done right the first time this is the information i have gotten from the manual of the unit # Kenwood 7039 # format: MPEG1, MPEG2, DivX # Picture Store # MPEG1: 320x240, 352x240 # MPEG2: 640x480, 704x480 # Divx: 352x240, 352,288, 720x450, 720x576 # Audio # MPEG1/2: MPEG audo layer 2 # Divx: MP3, Dolby Digital # Audio sampling freq: 32/44.1/48 kHz # Audio bit rate: 32-384 kbps (only constant bit rate)o # # must have mpg, mpeg, mpe, m1v, m2v extensions # # Screen specifications # 156.2 x 82.4 # pixela # 336,960 = 480Hx234Vx RGB I am thinking the process I want to do is 1) extract out the sounds, to wav and then re encode ? or if already in mp2/3 save it and use it later as is. Maybe normalise the sounds level as well, I hate having to turn volume up and down when I change tracks 2) re encode/ transcode the video into one of the acceptable formats, so I am thinking divx because it seems to be a better compression with mp3 inside a mpg file ? I was thinking to try and keep the aspect ratio but to change the size down to the actual screen size - there for I can keep more files on the DVD Any help would be appreciated Thanks Alex 2)
