Removing Commercials with Mencoder and EDL

DV 720x576
by GeBu 02 Apr '06

02 Apr '06

Hi, I have DV camera and when I download video to PC it has resolution 720x576 (5:4) but inside it has 16:9. When I play the video the picture is tapered in many players (mplayer, VideoLAN). Windows Media Player is Ok. I would like to change it without reencoding (to let it in DV format). Is it possible? I used "-force-avi-aspect 16/9" with -ovc copy. It helps for playing in mplayer, but VideoLAN it show tapered video again. Do I need to resize to 1024x576 maybe to 720x405. I would like to change aspect to 4:3 and resize video to 720x576, 640x480, 360x288 or 320x240 without reencoding (to let it in DV format). Is it possible? Any idea how to work with video from DV camera? Jirka (GeBu)

Mencoder report error when trying to use b-frames with lavc mpeg1/2/4 codec
by yong 27 Mar '06

27 Mar '06

Here are the example options i using: -audio-preload 2.0 -oac copy -ovc lavc -lavcopts vcodec=mpeg2video :autoaspect:keyint=300:vbitrate=1200:naq:lumi_mask=0.3:dark_mask=0.3 :p_mask=0.1:dc=11:trell:mv0:mbd=2:qprd:cbp:predia=2:dia=2:preme=2 :vb_strategy=1:vmax_b_frames=0 -of mpeg -o "%userprofile%\desktop\%~n1.mpg" if i set vmax_b_frames equal or more than 1 mencoder will report this repeatly: [mpeg2video @ 00D8CC98]Error, Invalid timestamp=0, last=0V:0.000 [0:0] Muxer frame buffer cannot allocate memory! ... and end up with a 0kb of file. im sure the cvs version of libmpcodecs(ve_lavc.c?) have problem, because the older version of libmpcodecs works fine with b-frames encoding.

x264 file playback is too slow!
by some one 26 Mar '06

26 Mar '06

Hi, I'm running debian sid @ P4 2,3 GHz CPU. I encoded a raw DV file to x264 using the following command: mencoder -ovc x264 -oac mp3lame -aspect 4/3 -x264encopts subq=6:4x4mv:8x8dct:me=3:frameref=5:bframes=3:b_pyramid:weight_b -lameopts q=0:preset=insane -vf pp=ci -o mencoder.mp4 dvgrab-001.dv Now when I try to play the file with mplayer, it's too slow and I get this message: ************************************************ **** Your system is too SLOW to play this! **** ************************************************ I tried all the recommendations like: -framedrop -nodouble -lavdopts skiploopfilter=all -nosound (with this option the slow CPU warning doesn't show up, but playback is still too slow) -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all I cut 10 secs out of the x264 file, so here I paste the link: http://s53.yousendit.com/d.aspx?id=0IUHBNNSVPXIA0DGYBMN7RNU27 Please help me out with this. why is the playback so slow? Did I do the encoding wrong or what's wrong with the playback? I don't think the CPU is too slow, and it's %95 idle before I play the file. thanks! long live mplayer + x264 _____________________________________________________________ Send an Online Greeting Card http://www.UltimateEcards.com Get your Free Patriotic Email account NOW! http://www.ProudAmericanEmail.com 100s of FREE email addresses ---> http://www.UltimateEmail.com

Strange FF behavior
by mrrs 25 Mar '06

25 Mar '06

I am burning dvds using a pvr-350, ivtv, mencoder, dvdauthor and growisofs. After much trial and tribulation, I have managed to get a dvd that is actually usable on my two standalone dvd players. The problem that I have now is that when Fast Forwarding through the video, rather than smoothly skipping through the video, I get slow motion, then jump, slow motion, then jump. I can't really tell, but I don't think it is proceeding through the file at the correct rate either ( 2x,4x,8x, etc). I copy from /dev/video0. non default ivtv settings are: ivtvctl -u 0x3000 ivtvctl -p 6 ivtvctl -f width=720,height=480 I am using the following for mencoder: inputfile=$1 outputfile=$2 bitrate=$3 # added deinterlace filter # changed volume from -10 to 10 # removed volume entirely, added options from mencoder docs # changed vqmin=1 to vqmin=2 mencoder -fps 30000/1001 -of mpeg -oac copy -ovc lavc \ -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:\ vbitrate=$bitrate:keyint=15:trell:mbd=2:precmp=2:subcmp=2:cmp=2:\ dia=-10:predia=-10:cbp:mv0:vqmin=2:lmin=1:dc=10 \ -mpegopts format=dvd:vaspect=4/3 \ -vf lavcdeint,harddup -noskip -o $outputfile $inputfile ( if anyone sees anything else stupid that I am doing, feel free to let me know that as well - I am really new at this. ) dvdauthor script: inputfile=$1 cat > dvdauthor.xml << EOF <dvdauthor> <vmgm /> <titleset> <titles> <pgc> <vob file="$inputfile" /> </pgc> </titles> </titleset> </dvdauthor> EOF dvdauthor -o $inputfile.dvd.d -x dvdauthor.xml growsisofs script: inputdir=$1 growisofs -Z /dev/cdwriter -dvd-compat -dvd-video $inputdir eject /dev/cdwriter Any assistance would be greatly appreciated! Thanks in advance.. markus __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
