Title: trying to get mplayer to play mpeg4/ogg/vorbis
Post by: ninsei on August 06, 2004, 09:48:10 am

Hi.  got MPlayer 0.90pre10-2.95.2 and i wanna convert DVDs to mpeg4 using ogg/vorbis sound.  I THINK i managed to convert the file right cause the video plays brilliantly but no sound.  mplayer says:

Detected OGG file format!
==========================================================================
*** Try to upgrade /root/.mplayer/codecs.conf from etc/codecs.conf
*** If it still does not work, read DOCS/codecs.html!
Can't find codec for audio format 0x200!
==========================================================================
==========================================================================
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffodivx] vfm:ffmpeg (FFmpeg MPEG-4)
==========================================================================
Audio: no sound!!!

any help is appreciated.

Do you have libogg (and libvorbisdec) installed?

I can play .ogg files fine with mplayer.


Si

May I ask how you converted the movies for the Z?  I'm interested in doing this too.  Is there any websites that explain this?  Preferably, convert them in linux?

mencoder -ofps 8 "$1" -o "$2" "${@:3}" -lavcopts vhq:vcodec=mpeg4:vbitrate=40:vrc_maxrate=70 -ovc lavc -lavcopts vbitrate=150 -oac mp3lame -lameopts abr:br=32 -zoom -vf scale=320:-3,expand=-1:-1:-1:-1:1,rotate=1 -sws 9 -af resample=22050 -srate 22050

Have fun with this script... I have another script to play them (sortof a hack) which should be simple to figure out, but let me know if you want me to look it up..

If you want to convert to ogm (encode audio to ogg vorbis and video to mpeg4) check out my site on the bottom of this text.

Sorry, didn't mean to hijack the thread.  Thanks for the pointers guys.

How is it coming along ninsei?  Would the vorbis stuff in the xmms package allow mplayer to play them?

got them to convert, installed the right libs (sorry i missed that).  mplayer plays them but sound is garbled.  i wanted to try ogg stead of MP3 cause i heard MP3 slows down the 5500.  and something to do with sound is definitely slowing down my mpeg4 videos.  The BEST results i've gotten so far is:

mencoder dvd://1 -srate 24000 -vop scale=320:240 -o office_space.avi -oac mp3lame -lameopts preset=15 -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate=150 -ofps 15 -sws 2

that works best with Dr. Z Video and even then it's not really watchable cause there's a lot of frame drops/hangs.  I'm about to try the mencoder opt that Luke-Jr2 posted.  thx for all the help folks.

Luke-Jr2's command line works fine.  Thx a lot!
