Hey guys
First i'd like to say that i know flash players can run x264 .mp4 files, but the site im uploading the videos has some bug with MP4 videos at the moment, im trying to convince them to fix that issue, but for now i have to stick to .flv files.
Im converting from divx/xvid to .flv, but without much success, im only getting very blocky videos.
I tried ffmpeg command line, megui, mencoder on command line, but i could only use pre-made commands i found on my searches, and found those commands only on old pages. Since everyone is using MP4 today, theres few discussions about getting the best quality/size ratio out of flv files.
As for Megui, i i couldnt get it to output a flv, i think its not possible, right ??
The requirements i needed are: conversion cant be too slow, around 250fps is fine (i know some avisynth filters can drastically slow the conversion down), size of flv output should be around 4mb / minute (max 5mb / minute), and i also wanted a 2 pass conversion. I tried to do a 2 pass conversion o ffmpeg, but i cant figure it out, seems like it needs some .mcf file with settings on it, and i dont know to create that file, and not a clue what settings to use in those mcf files.
Also, it seems that some people managed to get a x264 file in a flv contanier, is it really possible ??
I also tried converting divx to mp4 using Megui, it converted fine, and had good quality, so i renamed the .mp4 to flv uploaded it to the video site, but the flash player wont run it, no video and no audio, stays on black screen.
Please know that this site does not reconvert the uploaded files.
Thats it guys, i basically i needed 2 pass command lines for ffmpeg or mencoder to convert divx/xvid to flv with 2 pass, that doesnt take too long to convert (around 250fps) and results in decent quality flash video.
Sorry if im asking much hehe, hope anyone can help, thanks a lot.
