NOTE: "/dev/dsp" can probably be swapped out with [/dev/audio] .
mepis8 is built on debian lenny repos.
Debian's ffmpeg is missing alot of codecs but it works better than MENCODER for av sync web cam recording because mencoder did not keep the audio in sync.
for /dev/dsp to work it may require "alsa-oss.deb" the legacy compliance ap layer is likely needed. "?"
------------------
[check] "capture" control on it needs to be used to grab mic sound recording.

$ ffmpeg -i *yourvideo.AVI -vcodec msmpeg4 -ab 128 -b 592 -bufsize 4096 -mbd 1 -precmp 0 -cmp 2 -subcmp 2 -s 576x416 -padtop 32 -padbottom 32 -padleft 32 -padright 32 -qmin 4 -qmax 4 -pass 2 [q4-4-mbd1]new-p2-simple-msmpeg4.avi
/* I should now have a medium qualty copy with padding
for my TV dvd/divx player. */
-------------------------------------------
I some times just do a simple one pass encode set at -mbd 2 and I end up with the same quality that looks good on standard def TV. " What works well for me is the setting " ( -qmin 4 -qmax 4 ) my standard def TV dose not realy display quality set below 4. BEST quality is ( -qmin 2 -qmax 2 ) and setting the quality to belowe 4 makes the compressed file bigger... Pluss it takes longer to encode...
---------------------------------
I'm using a old pc with a 788mhz intel chip and it takes me over 30min to encode medium quality video set a qualtity 4 if i do a simple one pass encode using the old msmpeg4 Div3 codec... BUT if i try to encoded with divx in HQ it takes me for-ever on my slow pc.
---------------------------------
I wrote this and tagged it as ffmpeg
then posted it here at http://wardcraft.blogspot.com
so i can refer to this post in the future
when I wont to cut and paste instead of typing ever switch into terminal.
===================================== some ffmpeg NOTES :
ffmpeg -i *.avi -acodec mp3 -ab 96 -vcodec msmpeg4 -b 720 -ar 24000 -mbd 2 -aic 2 -cmp 2 -subcmp 2 -s 480x352 -padtop 32 -padbottom 32 -padright 32 -padleft 32 -r 23.98 -title X -f avi -qmin 3 -qmax 10 -t 00:02:00 new-480x352div3-tube.AVI
===================================== i coded the video like like this back when "?" i downloaded the video because i was trying to make the video aspect the same size as youtubes embedded flv player. But i don't think i like the aspect now. I had the file siting around so i uploaded it. it looks ok on veoh. I have some other file siting on cd's that i can dig up and upload later this week.
======================================
thx for reading.
I uploaded this video to veoh I used ffmpeg for the transcoding.
----------------------------------------
ffmpeg -i *.avi -acodec mp3 -ab 128 -vcodec msmpeg4 -b 720 -ar 44100 -mbd 2 -aic 2 -cmp 2 -subcmp 2 -s 476x342 -padtop 32 -padbottom 32 -padright 32 -padleft 32 -r 23.98 -title X -f avi -qmin 3 -qmax 10 -t 00:02:00 new-veoh-540x406div3-tube.AVI
------------------------------------------
it took a long time to upload but it looks ok
a lot better then it would on youtube.
i shrunk the embedded player to fit the blog 440x420 but
it's larger sized @ veoh.
-------------------------------------------
i padded the video so i can burn a copy to cd and play on divx/dvd player without the overscanning cutting of the English subs.
-------------------------------------------
This is one of my favorite eps of bleach . watch it . thx bleach ep 114
-
normally i use linux with ffmpeg and mENCODER to convert video into [xvid - avi] but it can be done with windows XP.
-
download pspvideo9
install pspvideo9
and then click my computer and browse the the program folder
till you find the folder with ffmpeg in it.
drag a copy of the ffmpeg folder to your desk top.
-
also grab a copy of cmd.exe from yor system folder and place it in the ffmpeg folder.
-
place video in the ffmpeg folder . -
click on cmd.exe it will bring up a command shell
that you can type into.
@command line.
ffmpeg.exe -i inputfile.avi -vcodec xvid -vtag XVID
-s 320x240 -r 23.98 -b 592 -maxrate 728 -qmin 3 -qmax 3
-mbd 2 -acodec mp3 -ab 192 -ar 48000 NEW-VIDEO-XVID.AVI
ffmpeg runs in emulation on windows
I only used it a few time on windows it works if you wont to view the video your going to need a player like vlc video lan client or mplayer.
-
another free video tool that works with ffmpeg is super do a google search for [super and flv]
super uses ffmpeg and mENCODER.
Mencoder can be used to copy video made by ffmpeg.
i use mencoder to fix audio sync and the codec header.
@commandline
mencoder.exe old-video.AVI -ovc copy -oac copy -o new-video-xvid-XVID.avi -ffourcc XVID
NOTE: -fforcc XVID will make the codec header
xvid in capt XVID when i use linux ffmpeg
only vtags the video in lowercase xvid and
some of my players will not play the video.
so i run Mencder on the video to fix it.
-
so before you buy $$ a video encoder try some of the free ones
you don't need the gui's their just front ends for
ffmpeg command line or some other command line encoder.
#
I don't test a lot of widows apps
but " pspvideo9 and super "
are keepers because i like using
ffmpeg and mENCODER.
but i to lazy to build them from source.
