on2 vfw vp6 bonkers guied for idjits

i'm sorry i like my video right side up.

on2 vfw vp6 bonkers "flv" guide for the rest of us

work around

( mux flv example source sound ) with ffmpeg. ==================== (0) CRAP CRAP CRAP CRAP avs crap example $ wine ffmpeg -b 128 -ac 2 -ar 44100 -i "temp-vp6.avi" -vcodec copy -i "example.avs" "example-vp6.flv" CRAP CRAP CRAP CRAP. fixthis crap :? move on to part one. skip part zero. fix: (1.........................) fix this by using my ffmpeg taget vcd-ntsc workaround. (2.) open vcd with " virtualdub mod ". flip the video with virtualdub streem filters. save as on2's vp6 / avi. (3) now use sh0dan's patched win ffmpeg binary. fix: new: $ wine ffmpeg -b 128 -ac 2 -ar 44100 -i "new-vdub-vp6.avi" -vcodec copy "new-ffmpeg-vp6.flv" ====================== it all worked after some detective work. LINKS-1: http://sh0dan.blogspot.com/2006/09/command-line-flash-8-flv-encoding.html LINKS-2: (patched ffmpeg) http://klauspost.googlepages.com/ffmpeg-VP6-FLV.zip ===================

mencoder allso works nicely.

(4) CODE: mencoder *.avi -oac copy -ovc vfw -xvfwopts codec=vp6vfw.dll -o out2.flv (5) #OR: $ mencoder *.avi -nosound \ -vf flip -ovc vfw -xvfwopts codec=vp6vfw.dll -o out1.flv ================== so why waste all this time tweaking with ffmpeg with wine on my linux system ? while a native mencoder feels a little easier. But virtualdub is fun to play with some times. ooh pretty gui fun. 10moy2009

youtube h.264 flv codec sucks

youtube h.264 flv codec sucks. h264 hates old slow computers and FLV players are pigs. Work around this with ffmpeg. ./ffmpeg input.flv -vcodec copy -acodec copy "output-mpeg4--6moy2009.mp4" (LQ) ./ffmpeg -i *.FLV -vcodec flv -acodec libmp3lame -ar 44100 -ab 32 \ -s 320x240 -aspect 16:9 -b 350 -r 25 \ "OUTPUT-LQ_4tube-vcodec-flv--b350--ver3-mp3.flv" ------------------------------ //////////// ////// /// youtube safe? video format " will look like crap. SO TRY Qscale for averAGE-quality... NON-youtube videos ============= ./ffmpeg -i *.FLV -vcodec h263 -s 352x288 -aspect 16:9 -b 350 -r 25 -qscale 4 \ -acodec libmp3lame -ar 44100 -ab 124 \ "OUTPUT--averageQ-h263--avi-.avi"
